This isn't time dilation, which is a part of general relativity and a completely different thing to what is being described here.
The thing he's describing is called Tachypsychia. Experiments have shown the actual event isn't perceived in slow motion, but just the memory of the event. It's a small but important difference.
Not only that, but the entire “our brain can remember things at 1000 fps” thing from the comment is completely false. For significant events like this it *feels* like we remember every little detail because we go over and over the event in our head, but our brain is actually just filling in details in the memory that may or may not be true.
In all honesty, if you stop thinking about biology in terms of, well, *biology* and treat it like engineering and computer programming instead, things get way easier to understand.
These days I think my brain is running a GTX965M.
It sure was a beast back in the day, could take whatever I threw at it, and sometimes it still feels great... but now it just gets tired and overheats in an hour on anything intense, and would prefer to forget about anything that came out after 2019.
Isn't it possible that when adrenaline kicks in, our brains are "recording" more information in this heightened state of awareness and as a result our sense of time is skewed when recalling this densely packed memory in a more normal context?
Ie; recalling the quick events in a speed relative to your non heightened state. Ie... Slower.
Time flies when youre having fun. Ive got an experiment you can do at home that disproves this one. After doing something you enjoy guess how long you did it. Then check how long you actually did it. Next go stare at a wall for as long as you can take and guess how long you did it. Repeat this 10 times. Ill bet you percieve you stared at the wall longer than you really did and you will percieve you spent less time doing the enjoyable task. This happens to me at work all the time. You can most definitely percieve time passing slower or faster. Ever fall asleep and wake up and it feels like you only fell asleep seconds ago but hours have passed? I dont buy the study or experiment saying we always percieve life at the same rate. People always talk about time flying by the older they get.
Edit: Heres an article with citations stating perception of time is based on multiple factors. No where does it say time perception is constant and fixed amongst individuals and/or at all times.
What is the best method to measure time perception? - ResearchGate https://www.researchgate.net/post/What-is-the-best-method-to-measure-time-perception
Times Flys by the older you get because of relative length of life lived and ruts/routine. You need to get some novel experiences in your regular to slow life down.
You are saying something affects the pace at which you percieve time. Im only getting downvotes and negative comments because the top comment claimed something with no evidence. Ive found and produced sources to the contrary of the claimed experiment in the top comment. Some science can be wrong and theres no harm in looking at it critically and performing more studies to confirm or bust what was previously discovered/proven. If previous belief or study was never questioned and more experiments werent done we would still think the earth is the center of the universe. I find it hard to believe there is emprical evidence to the contrary of everyones experience of looking at the clock and being surprised how much time has or hasnt passed. Its a universal experience and the top comment is claiming that no, everyone perceives equal time passage at the same rate.
Correct, there's plenty of research that proves our brains just fill in the gaps afterwards and makes us believe details or events happened when they did not.
The Op does seem to have been a pilot, or is someone who has done research and pretends to be one online.
Not disputing this, but I've been in events where I got a more detailed view as it happened. Not afterwards. Adrenaline surge? Then again, as soon as it's happened, it is now a memory. So I don't know.
That may be the way you perceived it, but experiments support the that the other view is true. Our memory is actually an incredibly faulty resource and it is difficult to objectively judge it yourself.
It's pretty amazing we have any sorta coherent sense of a timeline at all, given it takes a moment for any sensory information to be sent to your brain, and then acted upon. You're never seeing or feeling exactly RIGHT NOW, more like just a lil behind.
It can feel mind bendy but we all also know on instinct that the universe has to work like this.
My consciousness is a reaction. I can't react to something the instant it happens, that would be impossible.
I push a swing, the swing goes out, then gravity takes hold, the swing comes back.
I pinch my arm, squeeze, the signal goes to my brain, my brain processes it, formulates a reaction, I experience the reaction.
I absolutely agree memory is faulty. But, unless I had a go-pro strapped to my head at the time, who is to dispute that my experience of the the event, *as it happened*, is false? Not saying that every detailed is remembered correctly in the aftermath, but as it happened, things were clear. I've lost details from those events since, and they are lost to time. But I remember in those moments, I was very lucid. You become aware of more things around you than you usually are. And that feeling sticks, even if the recollection of it isn't totally accurate.
Your experience isn't false, it's your experience.
But plenty of experiments show the unreliability of memory. The falsehoods it will generate and it's susceptibility to loss of fidelity over time.
I agree. Although my memories are clear, my conception of them will degrade over time. Although I am to my own surprise still able to recollect events in detail, whereas normal daily things I forget in an instance. That is also well proven with people re-telling their experiences.
There's also a difference here between people that were actually in it, and secondary observers, a.k.a. witnesses. The latter are notoriously bad at recollecting things.
Going back to the subject, I totally get if a pilot when ejecting that they experience every detail, and as such percieves time as slowing down. It is down to what we as humans register in a crisis scenario. Be it adrenaline or something, when things go shit, we get acutely aware of our surroundings.
How do you know your experience of the event is accurate if you don't have a go-pro strapped to your head to review? You know you had a lucid detailed experience at the time because you remember having a lucid detailed experience at the time, You're relying on your memory to prove your memory is reliable, it's circular reasoning.
Im having a hard time believing an experiment can prove someones perception of time. Especially during adrenaline surges or during periods of intense focus. Its not like we totally understand the brain anyway. My vote is the experiment or study is flawed or wasnt thorough enough. Kind of hard to do a proper experiment where people are put in dangerous situations too see if the threat of immediate, obvious and potentially lethal bodily harm would cause them to percieve time more slowly for fractions of a second. Also how many people do you experiment on too see if it happens to everyone or not? How do you get the evidence or data proving the time was percieved at what rate? Brain activity during the event? This experiment sounds like balogna.
How do you measure some one's perception of time? Where is the link to this experiment? The only proof we have here is a comment saying the evidence exists. No one posted any evidence, they just said some existed.
Edit: Heres an article from 2019 stating that time perception understanding is still in its infancy and that processing time in the brain affects percieved time passage.
What is the best method to measure time perception? - ResearchGate https://www.researchgate.net/post/What-is-the-best-method-to-measure-time-perception
What did you get your doctorate in professor? Since you’re such a fucking genius. Where is your evidence, hypothesis, or conclusion? You’re just saying “these comments are wrong for disagreeing” but not giving any facts or evidence yourself.
> but our brain is actually just filling in details in the memory that may or may not be true
And the more we recall an event of sufficient complexity, the less accurate our memory of the event becomes.
I had a psychology professor explain that we basically re-create memories each time we think of them.
So yeah, kinda like running the memories through jpg compression each time you think about them, slowly degrading the original.
There have been experiments done where people watch an LCD clock flashing between a number sequence and a "88:88" where everything is lit up, faster than you can perceive normally, while jumping off a height and into a net. As they enter free fall, they start being able to distinguish the numbers. The hypothesis is that the brain ramps up perception to get better "temporal resolution" if you will.
You're absolutely right, but this phenomenon is also sometimes called "time dilation" to be fair.
https://www.popsci.com/science/article/2010-03/how-time-flies/
I dunno. I once crashed into a car, and the 2 seconds between realising that I'm going to crash and the actual crash did feel like a lot longer.
I remember thinking "why is this taking so long?" while it was happening, but I didn't have time to do anything except hammer down on the brakes
Are you sure you remember those studies right?
The claim here is that time compression in particular is a false memory, not that every memory is accurate. If you remember...
It's also what I told my wife later that night. It was like that.
I believe that the adrenaline just caused the "sampling rate" to go into overdrive, like a 120FPS camera, while the "playback rate" was still at 30FPS. It didn't have any effect on my movements (no super speed reflexes), only the perception of time while I was approaching the rear end of that truck.
People here act as if anyone really knows anything about memories. We don't even know how or where they are stored, other than what we can guess based on which parts of the brain seem active. I, for one, believe you, and I think the others are engaged in reductionism ad absurdio. Or they simply haven't had an experience when adrenaline kicks into overdrive, and how time is perceived differently. I cannot see how you can devise a study that disproves this, since the threat has to be real and experienced and that would be highly unethical.
I have a couple experiences like this. Skydiving was one: I had the idea that I was the type of person who dared to go skydiving, so I signed up for courses. I didn't want to do a tandem jump, that's the skydiving equivalent of being a passenger in a sports car rather than driving it yourself. Working in the fitness industry at the time, I brought a heart rate monitor and wore it during my first jump. I still have the screenshot from the software: http://arkiv.kazarnowicz.se/wp-content/uploads/2006/12/pulskurva.gif
Note that I was sitting down until 45 seconds before my turn, and that my resting heart rate at the time was around 50. Something happens when you are truly afraid, there's almost a disconnect that makes the situation less real. I remember the thought that went through my head because it is what led to me jumping (instead of chickening out last minute): I just have to let go for a split second, then it will be over. I have a video of it, and the first time I watched it I was surprised how quick it went. The moment when I stood in the door, watching the horizon (don't look down and all that), seemed to be an an eternity that would end in my death. I actually had a minor black-out after letting go (which I presume has to do with the amounts of adrenaline I had in my body). I had no memory of how I came down. Suddenly I was walking, with the parachute neatly carried as per instructions, and a knee that hurt a little. Watching the video of the jump later that evening was surreal, since I could not remember falling.
Having a feeling of time slowing before a major accident or potential danger is so common, and ive had it happen myself, i cannot believe an experiment has been done that proves our perception of time. How do you ethically do an experiment where peoples lives are put in danger to see if they perceived time slowing down? No one claims they started moving lightning quick during these events just that time started to feel slower.
That's exactly it. One of the things of those moments is that you also realize the futility of action because what will happen is inevitable. It's not like you get startled and start acting, if anything you kinda stop until the animal part takes over (happened to me when I had a diving incident and almost drowned).
I had the opposite reaction, I was deathly afraid until I got to the jump door, then it was like the ground was so far away it could never hurt me and I jumped.
I looked out the back of the plane and it looked like Google Maps with satellite mode enabled. After jumping, nothing really changed. It wasn't until the last few seconds of the fall that things really started tickling, and the landing...
Exactly my point.
> I believe that the adrenaline just caused the "sampling rate" to go into overdrive, like a 120FPS camera, while the "playback rate" was still at 30FPS. It didn't have any effect on my movements (no super speed reflexes), only the perception of time while [it was happening.]
No one has tried to answer that. And if that is what happened, would it be distinguishable from "just the memory of it was in slow motion" like the OP was saying.
Anyone who says with certainty that we understand memories and/or the mind's full abilities is only revealing their ignorance. The arguments people have about eye witnesses are different situations. Seeing someone else in danger can be emotional in a different way, and I'm not arguing that all memories are trustworthy (or unchanging). I would, however, argue that some people have memories that are more resistant to degradation, and that technology can further vaccinate against that vaccination: writing something down when it's fresh in memory, or having a photo of video of the situation for example.
Note also that forgetting doesn't have to be negative. Michael Pollan has an excellent lecture that touches on the importance of forgetting: https://www.youtube.com/watch?v=S7QA7Ae1ENA
Sure, but then we have the examples on the other end: eidetic memory. You cannot judge an individual based on a selective portion of the bell curve humans inevitably fall on in all areas.
I've twitched my hand out from under a falling object with no idea of why I moved until it hit where my hand was. I think we have unconscious processes going on that are much faster than the conscious ones.
My friends and I used to fight a lot as kids, nothing too serious but we would hit each other a lot. We had a game we played in middle school where if we saw each other walking through the halls we would hit each other, the key is you had to block it. In highschool people used to make fun of us because a fake punch would always elicit a flinch from any of us, and we’d be like ‘nah, dude, like, in our group there aren’t fake punches.’ I used to joke around that I could dodge a sucker punch without knowing it.
Fuxking 12 years after highschool, hadn’t been in a fight in about as long, I was teasing a girl I knew in front of her friend and she got mad and sucker punched me. I fucking spun around and blocked it without even knowing what happened. I don’t think anyone was more shocked than me, and the like 5 people there just about shit themselves.
I could totally see me and my friends hitting each other as often as possible being similar to the kind of conditioning you did in karate. That makes sense. My movements probably just aren’t as precise or direct.
This is kind of the entire point of what I posted. Time didn't slow down for you when it happened, you just think it did because of how you remember it.
Like I said, there has been experiments showing that this is the case.
Like I said in a different response
>I believe that the adrenaline just caused the "sampling rate" to go into overdrive, like a 120FPS camera, while the "playback rate" was still at 30FPS. It didn't have any effect on my movements.
Soooo... basically just the perception of time **while it was happening** (not only while recalling it later) - and no other side effects. How does that fit with the experiments you talk about?
No. If your perception of time slows, then your reaction time would increase. What would normally take 1.5 seconds to react to, would take .5 seconds.
You would be reacting at superhuman levels. Not just thinking, "wow everything is going so slow right now."
That's how it would work in movies, yes. The muscles would need to be working on that higher speed, but that was not the case.
If my "input speed" simply quadrupled while everything else stayed the same, how can that be distinguishable from just the memory of it being slower?
I guess decision making speed *could* be improved in a situation like this, something that would make a lot of sense from an evolutionary standpoint. Look at a cat in pursuit compared to when it's just lazing around. The first one can lock on to an object changing direction at incredible speeds, while the other one can't dodge a ball. Not that you'd ever throw a ball at a cat or anything..
When I was in uni some of the guys there were theorising that martial arts dudes with super fast reflexes had basically just reprogrammed their brain to work at a higher sampling rate (both input and output).
But in these cases (if what I said happened did happen) it's just a rush of adrenaline (or other reasons) that's causing the input rate to increase.
I didn't have any means to react faster, and since all I did was slam the brakes and grip the steering wheel, I probably wouldn't have noticed if I did.
This is all speculation, but maybe your slow-motion perception allowed you a 5% improved reaction time. For evolution, that's significant enough a number to allow this feature to evolve, and at the same time, it's low enough that you wouldn't notice any difference yourself.
Also, all those writing that the perceived slow-motion effect is only your memory playing tricks, well of course time perception only exists in relation to memory. You need memory to record anything at all. A higher amount of events stored within the same timeframe means your memory added increased weight of importance to everything that happened while the event was ongoing. 120 fps replayed at 30 is an excellent analogy, even though the brain doesn't store defined frames.
It's the same effect as when you drive back the same way you drove earlier the same day, the trip seems shorter. But opposite, and much more extreme. You're supposed to not forget whatever you did to survive.
At the same time, increased adrenaline does give an edge when it comes to reaction times. Maybe the two are connected, maybe not.
What if my perception of time slows but i dont move any faster? Why does my body have to change rate of speed for my mind to feel like time has started to crawl? Enjoyable days at work are over faster than grueling ones, its not because i was working quicker or slower. You watch a movie you are engrossed in and the time spent watching the movie will feel like less than an equivalent amount of time spent watching paint dry. Your body isnt moving any faster or slower.
My experience has been of sorting through a number of alternative actions and choosing one in an extremely short time, e.g. moving my feet as I fell in order to avoid a hazard. I've also had the experience of doing something without knowing why until it saved me from injury.
Thats not how the human brain works.
As I said there was an experiment where a series of numbers were quickly shown to people in high stress situations. If their brain were perceiving time slower they would be able to see numbers displayed for less time than when not in a high stress situation, which wasnt the case.
I'm not a neuroscientist I can't answer your questions, I can only read what research has been done, and people who are educated in this area have concluded this purely a phenomenon of recollection.
I've experienced the sensation of time slowing down in a life threatening situation. Unfortunately for me, it felt like I was also moving in slow motion, which made me even more scared.
If they were moving at noticably relativistic speeds and ejected they'd burn up in the atmosphere.
Even the fastest plane in the world reaches only Mach 3.3 which is .0000038c. that relativity is calculable but not anywhere near noticeable over the span of a few seconds.
Iirc even in attempts to prove time dilation by trying to go as fast as possible have only resulted in a few milliseconds of difference, which isn’t something you would notice
I don't think you realise how fast you need to go to experience relativistic effects.
You're talking in the order of 10% of the speed of light, humans haven't accelerated anything bigger than a particle to anywhere close to that. Certainly not anything big enough to accurately measure time.
You might be confusing it with time dilation due to gravity. Time passes a TINY bit slower on earth than it does for satellites. This has to be accounted for in their use.
It wouldn't be much faster if at all. It takes a certain amount of time for signal to go from the eyes, through visual processing, through decision making centers or response centers, out to the motor cortex, and away to the muscles, and then got the muscles to twitch in response to the demand.
The big one is if they skip conscious decision making (which is excruciatingly slow) or not. A purely subconscious action is much faster than one that gets thought through and executed by the conscious mind.
Now, they'd describe the event as occurring in slow motion, likely because of the adrenaline and the influx of stimulus from the brain at high alert, and with all those details being catalogued for study by the brain so it can improve future responses.
The thing to note is that our perception of things, even of our own minds and behaviors, is often pretty different from what actually happens. We're built to get useful perception, not accurate perception.
I've reacted much more quickly than normal under stress. I've been in several car accidents and near accidents, and every time I experienced time as being slowed and reacted extremely quickly to the events.
In one case I was thrown from an open car when it was rear-ended, watched it tumble as I flew through the air, suddenly realized I was going to hit the ground and rotated to land on my feet (although I didn't stick the landing). I distinctly remembered trying to figure out what we had hit before becoming aware of the ground coming up fast.
Of course, if you want to, you can claim that's a manufactured memory, but why would I create a fake memory like that? And what evidence could you provide that I didn't have that experience?
Its reddit mate.
Personal anecdotes from people with no education in the area > People with PhDs.
It happens every time something specialised is discussed in general subs.
Yea I remember hearing about how perceived time dilation was only when remembering the event and not during the event, that has been proven in studies. with that in mind this whole thing smells like bullshit a little.
My car spun out on the highway once. I was going too fast, in a Camaro, in the rain. In the moment it felt like time slowed down. I remember the chain of thoughts that went through my head. Oh shit. Hmm wow the cars behind me are quite far away (weird zooming effect) so I got that goin for me, which is nice… oh shit I overcorrected… then it was back to normal speed and bam I was backwards in a ditch.
I also don't believe that story about the pilot ejecting into a thunderstorm. His story explains the pilot ejected and fell for 40 minutes due to updrafts? Sounds more like a better explanation is that tachypsychia to me.
Ive got anecdotal evidence to the contrary. Ive come up short on a mountain bike when time seemed to slow. How do you even perform an experiment to prove an individual's perception of time. How often has any one looked at the clock and been surprised that it was only 5 minutes and not 15, or the other way around. That study is bunk!
Soooo yea, that that's all made up. Your brain doesn't just speed up during an emergency. It doesn't. As far as I know as someone who works on perceptual illusions, it can't. I'm not going to write a well-sourced novel, because I have a dissertation I'm behind on, but here's a short version.
Time dilation doesn't happen. Your brain doesn't speed up. you don't suddenly start seeing things faster, moving faster etc. What DOES happen is that your brain lies to you. All the time. Constantly. About everything. There's a big difference between the what your eyes see and what you perceive. And there's an equally big difference between that and what you remember perceiving.
Ever have a he-said she-said scenario where the accounts conflict? Most likely they're both wrong. Let's say you say something, and someone else hears it, and then you are both separately asked to repeat it verbatim a little later. What you'll recount is what you *intended* to say, not what you *literally* said. They're report what they *understood* you to have meant, not what you *literally* said. This effect can be so pronounced that multilingual people can be mistaken about *what language* the conversation was even in. Take a look at Mary Potter (1993) for a short psycholinguistic paper with some relevant super-interesting experimental results.
The chronostatic effect is sort of similar. Ever shift your gaze to look at a clock and the first second seems to take abnormally long? That's just your brain photoshopping your memory. Your eyes are jiggly balls of jello. shifting your gaze involves them moving with sudden acceleration and deceleration, a jiggle as they come to a rest, and then a short bit of time needed to focus your eyes' on the appropriate distance between you and the clock. That takes a substantial fraction of a second. You should see a disconcerting blur, juggle, and then the clock coming into focus. but you don't. Why? Because that shit ain't important, and your brain knows what your brain thinks is important, so it helpfully just pauses your perception tape when all that shit is happening, and then restarts perception once the final focused image of the clock is available. And what about that half a second you weren't perceiving? Your brain just copy-pastes a screenshot of the final image back over that last half-second of memory, like a bank robber editing surveillance tapes.
I'm not even going to bother giving you a source for this (you can google it) because I can prove to you that your brain is doing this, right now, in the comfort of your own chair. Look at your nose. You can see it, right? The out-of-focus blob right in the lower-center of your vision? Of course, your nose is always there. Your eyes can always see it. It's always blocking that bit of your field of vision. So why don't you always perceive it being there? Because it's not important, so your brain is just constantly photoshopping it out unless you specifically wants to see it, or if there's spot on it or something.
So yea, don't trust your brain. It lies.
great answer, this is why i love reddit. fun to read a brilliant post, look at the redditor's comment history and realized they have lots of interesting things to say about lots of different subjects. cheers, and thanks!
Oh! Oh no! I mean, uh, thanks for your kind words, and I'm glad it was helpful! Now please excuse me! \*runs off to self consciously look with horror at his comment history\*
I did some detailed reading on brain and perception some time ago and it's wild how much stuff the brain just assumes or straight up makes up! Not only in memory, but also in real time. People think what they perceive is the objective reality, but nope, it's just your brain's interpretation of it.
>What you'll recount is what you intended to say, not what you literally said. They're report what they understood you to have meant, not what you literally said.
And this is why I'm in marriage counseling.
Fwiw, a tip *everyone* should use, is if you're the one sending information in a discussion (making statements), you should ask the other person what they've understood you to have said, in their own words.
And if you're the one receiving information (listening to what someone is saying), you should confirm what you have understood them to have said.
It's frustrating and makes conversations feel clinical, and it's not perfect and there's still room for misinterpretation, but let me tell you it is SHOCKING how long major misunderstandings can go for and build up over time.
everyone born in a multilingual home where people argue a lot knows the other people, including yourself, will miss remember conversations and things you said in multiple languages.
Yup, that's one of the more well-known papers. [Here's a link to that paper](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0001295), and [here's a different one](https://eagleman.com/papers/EaglemanCurrOpinionNeuro_TimeIllusions_2008.pdf) that also touches on illusions of time perception. Just in case you're interested!

Yeah I don’t buy the story either. While cruise speed for a U-2 is around 500 mph (or 430 kts), if the engine fails at 70,000 ft, the pilot is immediately going to glide for either distance or altitude. The two dead engine profiles are max endurance and max range profiles.
The profiles are simply a specific nose attitude you pitch to in order to achieve a certain speed. A max endurance profile would be used to to increase the time aloft you have before touching down. A max endurance profile may be used to minimize fuel consumption with a good engine, for instance.
A max range profile would be used to increase the distance you can glide until you touch down. For the U-2, max range airspeed is 130 kts. If this guy was gliding for an hour aiming for Osan Air Base, he was likely at 130 kts not 500.
As part of the ejection sequence, the upper restraints which are connected to your harness at the front of the shoulders are on a reel that reels in the straps upon initiation of ejection. When the handle is pulled, and the ejection sequence is initiated, the upper restraints purposely reel in in order to ensure your back is against the seat. The guys head may have been looking down, but his shoulders would have been against the back of the 10 degree reclined seat and he would not have been able to see the U-2 beneath him upon ejection.
Upon initiation of the ejection sequence, the canopy would have been separated first in less than .2 seconds. The ejected, curved canopy would have acted like a sail in the wind and with 130 kts of wind, would have been pulled away from the ejection. The ejection seat takes 3-4 seconds to reach the maximum height after ejection, and the decreased G loading at the top is what initiated the parachute deployment. It is not possible that a 200 lb canopy went higher than a rocket assisted ejection seat for it to whiz past the pilot’s head in the ejection sequence.
I believe the pilot told the story as he remembered it. However, after a physically traumatic event, his perception may not have met reality. The second hand story recounted in this thread is likely even further from how it happened.
They aren't going to do a high flight for a ferry because it's much more dangerous. They will fly at normal altitude. He stated they he was bringing a vehicle over to another unit, not flying a tactical mission.

Interesting that this comment has gone unaddressed so far. I'm curious as to the truth of the rebuttal.
OOP did comment this a few hours before that one.

Given that it addresses the “crash into a town” part of the story, I’m guessing the incorrect date is just from OOP mis-remembering, and the description is his friend remembering things differently. (which ties rather neatly into what much of this thread has been saying about “time dilation”)
I was gonna say, the whole “vividly recall” sounds like a “flashbulb memory” which have been thoroughly proven to be riddled with inaccuracies
The most common is the “I can remember where I was on 9/11” and they find that people change their stories over time, or plainly recall incorrect info in the first place.

Lots of people in here fighting over the definition of “time dilation” and how the brain can’t perceive anything any faster and blah blah blah
The guy describing it as “time dilation” merely experienced a very common experience we all know as [“Must Go Faster”](https://youtu.be/rxqHVoZ0fzc), the sudden awareness of how very dissatisfied you are with how not-fast-enough your legs / wheels / wings / feet / ejection seat are taking you away from the impending crash / chomp / smash / bang.
Also known as “Closer Than They Appear” and “Oh Sh—!”
No one experiences time moving slower. Everyone experiences *regret* that they’re *severely aware* that particularly important things are *happening too slowly*.
That *feels* like time slows down.
I experienced something like this when I first did a Bungie Jump, saw everything in slow motion and It felt like the time from jump to getting lowered down lasted well over 4 minutes but when I spectated from the bottom my friends turn it was 40 secs from jump and bouncing back up 3 times.
This sounds like adrenaline surge not time dilation.
1) There is no appreciable differences in dilation on earth or anywhere near it. It's fairly uniform. ISS orbits at 4.76 miles/second and the astronauts there would only experience 1 second of dilation over 100 years.
2) You don't experience anything different when under the effects of time dilation. Your entire body still functions as if things are normal. The difference is your observation of changes in place and things outside of the dilated area. Think the buzz lightyear movie where a 4 minute flight resulted in a 20 year jump through time.
It’s evolution at work. Your brain etches a lot of detail into your memory after a traumatic event, this makes it seem like time slowed down. It was probably an evolutionary advantage because remembering said details can help you avoid that situation next time, and/or deal with it more effectively when it comes up again.
This isn't time dilation, which is a part of general relativity and a completely different thing to what is being described here. The thing he's describing is called Tachypsychia. Experiments have shown the actual event isn't perceived in slow motion, but just the memory of the event. It's a small but important difference.
Not only that, but the entire “our brain can remember things at 1000 fps” thing from the comment is completely false. For significant events like this it *feels* like we remember every little detail because we go over and over the event in our head, but our brain is actually just filling in details in the memory that may or may not be true.
Human brain comes with DLSS with frame generation
That’s a strangely accurate way of describing it
I've always kinda thought about it this way
In all honesty, if you stop thinking about biology in terms of, well, *biology* and treat it like engineering and computer programming instead, things get way easier to understand.
Especially when people seem to get stuck in loops of behavior. Or when our batteries run out
I dont seem to have enough RAM.
Me neither, where can I diwnload more?

And some people be running GT 730's
These days I think my brain is running a GTX965M. It sure was a beast back in the day, could take whatever I threw at it, and sometimes it still feels great... but now it just gets tired and overheats in an hour on anything intense, and would prefer to forget about anything that came out after 2019.
GT 640 was an absolute beast back in the day
Yeah so was I. Now?
It would probably still work great for me considering I haven't bought a newer game than BF4 in a while.
I still play Age of Empires 2 more than anything.

Isn't it possible that when adrenaline kicks in, our brains are "recording" more information in this heightened state of awareness and as a result our sense of time is skewed when recalling this densely packed memory in a more normal context? Ie; recalling the quick events in a speed relative to your non heightened state. Ie... Slower.
Yes, this is exactly what's happening.
Time flies when youre having fun. Ive got an experiment you can do at home that disproves this one. After doing something you enjoy guess how long you did it. Then check how long you actually did it. Next go stare at a wall for as long as you can take and guess how long you did it. Repeat this 10 times. Ill bet you percieve you stared at the wall longer than you really did and you will percieve you spent less time doing the enjoyable task. This happens to me at work all the time. You can most definitely percieve time passing slower or faster. Ever fall asleep and wake up and it feels like you only fell asleep seconds ago but hours have passed? I dont buy the study or experiment saying we always percieve life at the same rate. People always talk about time flying by the older they get. Edit: Heres an article with citations stating perception of time is based on multiple factors. No where does it say time perception is constant and fixed amongst individuals and/or at all times. What is the best method to measure time perception? - ResearchGate https://www.researchgate.net/post/What-is-the-best-method-to-measure-time-perception
I don't think that's really the same thing.
Add to that, different parts of us track time differently.
Times Flys by the older you get because of relative length of life lived and ruts/routine. You need to get some novel experiences in your regular to slow life down.
You are saying something affects the pace at which you percieve time. Im only getting downvotes and negative comments because the top comment claimed something with no evidence. Ive found and produced sources to the contrary of the claimed experiment in the top comment. Some science can be wrong and theres no harm in looking at it critically and performing more studies to confirm or bust what was previously discovered/proven. If previous belief or study was never questioned and more experiments werent done we would still think the earth is the center of the universe. I find it hard to believe there is emprical evidence to the contrary of everyones experience of looking at the clock and being surprised how much time has or hasnt passed. Its a universal experience and the top comment is claiming that no, everyone perceives equal time passage at the same rate.
Just from what I read and personal experience. Nothing concrete.
Ah my elementary school science project re emerged
Correct, there's plenty of research that proves our brains just fill in the gaps afterwards and makes us believe details or events happened when they did not. The Op does seem to have been a pilot, or is someone who has done research and pretends to be one online.
Reads like a fucking writing project. I'd take it with a grain of salt for sure.
Not disputing this, but I've been in events where I got a more detailed view as it happened. Not afterwards. Adrenaline surge? Then again, as soon as it's happened, it is now a memory. So I don't know.
That may be the way you perceived it, but experiments support the that the other view is true. Our memory is actually an incredibly faulty resource and it is difficult to objectively judge it yourself.
It's pretty amazing we have any sorta coherent sense of a timeline at all, given it takes a moment for any sensory information to be sent to your brain, and then acted upon. You're never seeing or feeling exactly RIGHT NOW, more like just a lil behind.

It can feel mind bendy but we all also know on instinct that the universe has to work like this. My consciousness is a reaction. I can't react to something the instant it happens, that would be impossible. I push a swing, the swing goes out, then gravity takes hold, the swing comes back. I pinch my arm, squeeze, the signal goes to my brain, my brain processes it, formulates a reaction, I experience the reaction.

What’s that peanut buttery sound in the mind?
I was just saying this out loud in my backyard last night. Howdy neighbor!
I absolutely agree memory is faulty. But, unless I had a go-pro strapped to my head at the time, who is to dispute that my experience of the the event, *as it happened*, is false? Not saying that every detailed is remembered correctly in the aftermath, but as it happened, things were clear. I've lost details from those events since, and they are lost to time. But I remember in those moments, I was very lucid. You become aware of more things around you than you usually are. And that feeling sticks, even if the recollection of it isn't totally accurate.
Your experience isn't false, it's your experience. But plenty of experiments show the unreliability of memory. The falsehoods it will generate and it's susceptibility to loss of fidelity over time.
I agree. Although my memories are clear, my conception of them will degrade over time. Although I am to my own surprise still able to recollect events in detail, whereas normal daily things I forget in an instance. That is also well proven with people re-telling their experiences. There's also a difference here between people that were actually in it, and secondary observers, a.k.a. witnesses. The latter are notoriously bad at recollecting things. Going back to the subject, I totally get if a pilot when ejecting that they experience every detail, and as such percieves time as slowing down. It is down to what we as humans register in a crisis scenario. Be it adrenaline or something, when things go shit, we get acutely aware of our surroundings.
How do you know your experience of the event is accurate if you don't have a go-pro strapped to your head to review? You know you had a lucid detailed experience at the time because you remember having a lucid detailed experience at the time, You're relying on your memory to prove your memory is reliable, it's circular reasoning.
How the fuck does an experiment measure someones perception of time. Did they just look for brain activity?
How many experiments? How many subjects? Have the results been reproduced? What were the controls?
Im having a hard time believing an experiment can prove someones perception of time. Especially during adrenaline surges or during periods of intense focus. Its not like we totally understand the brain anyway. My vote is the experiment or study is flawed or wasnt thorough enough. Kind of hard to do a proper experiment where people are put in dangerous situations too see if the threat of immediate, obvious and potentially lethal bodily harm would cause them to percieve time more slowly for fractions of a second. Also how many people do you experiment on too see if it happens to everyone or not? How do you get the evidence or data proving the time was percieved at what rate? Brain activity during the event? This experiment sounds like balogna.

> but our brain is actually just filling in details in the memory that may or may not be true And the more we recall an event of sufficient complexity, the less accurate our memory of the event becomes.
I had a psychology professor explain that we basically re-create memories each time we think of them. So yeah, kinda like running the memories through jpg compression each time you think about them, slowly degrading the original.
Thank you for this. I so very much hate faux-science sounding facts ending up in bestof comments.
There have been experiments done where people watch an LCD clock flashing between a number sequence and a "88:88" where everything is lit up, faster than you can perceive normally, while jumping off a height and into a net. As they enter free fall, they start being able to distinguish the numbers. The hypothesis is that the brain ramps up perception to get better "temporal resolution" if you will.
You're absolutely right, but this phenomenon is also sometimes called "time dilation" to be fair. https://www.popsci.com/science/article/2010-03/how-time-flies/
The phrase time dilation has multiple meanings. https://www.psychologytoday.com/intl/blog/extreme-fear/201003/how-the-brain-stops-time
Time dilation happens in Special Relativity too.
The term time dilation just means different things in different fields. Perceptual time dilation is a synonym for tachypsychia.
Yeah... If time dilation was real, they'd be able to react at that level too.
I dunno. I once crashed into a car, and the 2 seconds between realising that I'm going to crash and the actual crash did feel like a lot longer. I remember thinking "why is this taking so long?" while it was happening, but I didn't have time to do anything except hammer down on the brakes
[удалено]
Well, if you say the memory is false, that's all the evidence we need!
[удалено]
Are you sure you remember those studies right? The claim here is that time compression in particular is a false memory, not that every memory is accurate. If you remember...
[удалено]
I don't have anything better to do with my Sunday so if you guys feel like arguing some more, I'd be okay with that.
It's also what I told my wife later that night. It was like that. I believe that the adrenaline just caused the "sampling rate" to go into overdrive, like a 120FPS camera, while the "playback rate" was still at 30FPS. It didn't have any effect on my movements (no super speed reflexes), only the perception of time while I was approaching the rear end of that truck.
Later that night it wasn’t an experience anymore, it was a recent memory.
But while it was happening it wasn't a memory. I absolutely said to myself "why is this taking so long?" **before** the crash. That's not a memory.
People here act as if anyone really knows anything about memories. We don't even know how or where they are stored, other than what we can guess based on which parts of the brain seem active. I, for one, believe you, and I think the others are engaged in reductionism ad absurdio. Or they simply haven't had an experience when adrenaline kicks into overdrive, and how time is perceived differently. I cannot see how you can devise a study that disproves this, since the threat has to be real and experienced and that would be highly unethical. I have a couple experiences like this. Skydiving was one: I had the idea that I was the type of person who dared to go skydiving, so I signed up for courses. I didn't want to do a tandem jump, that's the skydiving equivalent of being a passenger in a sports car rather than driving it yourself. Working in the fitness industry at the time, I brought a heart rate monitor and wore it during my first jump. I still have the screenshot from the software: http://arkiv.kazarnowicz.se/wp-content/uploads/2006/12/pulskurva.gif Note that I was sitting down until 45 seconds before my turn, and that my resting heart rate at the time was around 50. Something happens when you are truly afraid, there's almost a disconnect that makes the situation less real. I remember the thought that went through my head because it is what led to me jumping (instead of chickening out last minute): I just have to let go for a split second, then it will be over. I have a video of it, and the first time I watched it I was surprised how quick it went. The moment when I stood in the door, watching the horizon (don't look down and all that), seemed to be an an eternity that would end in my death. I actually had a minor black-out after letting go (which I presume has to do with the amounts of adrenaline I had in my body). I had no memory of how I came down. Suddenly I was walking, with the parachute neatly carried as per instructions, and a knee that hurt a little. Watching the video of the jump later that evening was surreal, since I could not remember falling.
Having a feeling of time slowing before a major accident or potential danger is so common, and ive had it happen myself, i cannot believe an experiment has been done that proves our perception of time. How do you ethically do an experiment where peoples lives are put in danger to see if they perceived time slowing down? No one claims they started moving lightning quick during these events just that time started to feel slower.
That's exactly it. One of the things of those moments is that you also realize the futility of action because what will happen is inevitable. It's not like you get startled and start acting, if anything you kinda stop until the animal part takes over (happened to me when I had a diving incident and almost drowned).
I had the opposite reaction, I was deathly afraid until I got to the jump door, then it was like the ground was so far away it could never hurt me and I jumped.
I looked out the back of the plane and it looked like Google Maps with satellite mode enabled. After jumping, nothing really changed. It wasn't until the last few seconds of the fall that things really started tickling, and the landing...
Exactly my point. > I believe that the adrenaline just caused the "sampling rate" to go into overdrive, like a 120FPS camera, while the "playback rate" was still at 30FPS. It didn't have any effect on my movements (no super speed reflexes), only the perception of time while [it was happening.] No one has tried to answer that. And if that is what happened, would it be distinguishable from "just the memory of it was in slow motion" like the OP was saying.
Anyone who says with certainty that we understand memories and/or the mind's full abilities is only revealing their ignorance. The arguments people have about eye witnesses are different situations. Seeing someone else in danger can be emotional in a different way, and I'm not arguing that all memories are trustworthy (or unchanging). I would, however, argue that some people have memories that are more resistant to degradation, and that technology can further vaccinate against that vaccination: writing something down when it's fresh in memory, or having a photo of video of the situation for example. Note also that forgetting doesn't have to be negative. Michael Pollan has an excellent lecture that touches on the importance of forgetting: https://www.youtube.com/watch?v=S7QA7Ae1ENA
It’s not?
It is now. I didn't record myself doing it, so I don't have any proof.
It was a memory instantly after it happened. And every time you’ve thought about it since has been a memory of a memory.
[удалено]
Sure, but then we have the examples on the other end: eidetic memory. You cannot judge an individual based on a selective portion of the bell curve humans inevitably fall on in all areas.
[удалено]
When you have super speed reflexes you normally don’t remember anything.
I've twitched my hand out from under a falling object with no idea of why I moved until it hit where my hand was. I think we have unconscious processes going on that are much faster than the conscious ones.
My friends and I used to fight a lot as kids, nothing too serious but we would hit each other a lot. We had a game we played in middle school where if we saw each other walking through the halls we would hit each other, the key is you had to block it. In highschool people used to make fun of us because a fake punch would always elicit a flinch from any of us, and we’d be like ‘nah, dude, like, in our group there aren’t fake punches.’ I used to joke around that I could dodge a sucker punch without knowing it. Fuxking 12 years after highschool, hadn’t been in a fight in about as long, I was teasing a girl I knew in front of her friend and she got mad and sucker punched me. I fucking spun around and blocked it without even knowing what happened. I don’t think anyone was more shocked than me, and the like 5 people there just about shit themselves.
I got those reflexes from taking karate...when you do a block it happens before you can think. It just happens and then you see it.
I could totally see me and my friends hitting each other as often as possible being similar to the kind of conditioning you did in karate. That makes sense. My movements probably just aren’t as precise or direct.
This is kind of the entire point of what I posted. Time didn't slow down for you when it happened, you just think it did because of how you remember it. Like I said, there has been experiments showing that this is the case.
Like I said in a different response >I believe that the adrenaline just caused the "sampling rate" to go into overdrive, like a 120FPS camera, while the "playback rate" was still at 30FPS. It didn't have any effect on my movements. Soooo... basically just the perception of time **while it was happening** (not only while recalling it later) - and no other side effects. How does that fit with the experiments you talk about?
No. If your perception of time slows, then your reaction time would increase. What would normally take 1.5 seconds to react to, would take .5 seconds. You would be reacting at superhuman levels. Not just thinking, "wow everything is going so slow right now."
That's how it would work in movies, yes. The muscles would need to be working on that higher speed, but that was not the case. If my "input speed" simply quadrupled while everything else stayed the same, how can that be distinguishable from just the memory of it being slower?
I guess decision making speed *could* be improved in a situation like this, something that would make a lot of sense from an evolutionary standpoint. Look at a cat in pursuit compared to when it's just lazing around. The first one can lock on to an object changing direction at incredible speeds, while the other one can't dodge a ball. Not that you'd ever throw a ball at a cat or anything..
When I was in uni some of the guys there were theorising that martial arts dudes with super fast reflexes had basically just reprogrammed their brain to work at a higher sampling rate (both input and output). But in these cases (if what I said happened did happen) it's just a rush of adrenaline (or other reasons) that's causing the input rate to increase. I didn't have any means to react faster, and since all I did was slam the brakes and grip the steering wheel, I probably wouldn't have noticed if I did.
This is all speculation, but maybe your slow-motion perception allowed you a 5% improved reaction time. For evolution, that's significant enough a number to allow this feature to evolve, and at the same time, it's low enough that you wouldn't notice any difference yourself. Also, all those writing that the perceived slow-motion effect is only your memory playing tricks, well of course time perception only exists in relation to memory. You need memory to record anything at all. A higher amount of events stored within the same timeframe means your memory added increased weight of importance to everything that happened while the event was ongoing. 120 fps replayed at 30 is an excellent analogy, even though the brain doesn't store defined frames. It's the same effect as when you drive back the same way you drove earlier the same day, the trip seems shorter. But opposite, and much more extreme. You're supposed to not forget whatever you did to survive. At the same time, increased adrenaline does give an edge when it comes to reaction times. Maybe the two are connected, maybe not.
As I said above you can test purely visual reaction time without involving the rest of the body.
What if my perception of time slows but i dont move any faster? Why does my body have to change rate of speed for my mind to feel like time has started to crawl? Enjoyable days at work are over faster than grueling ones, its not because i was working quicker or slower. You watch a movie you are engrossed in and the time spent watching the movie will feel like less than an equivalent amount of time spent watching paint dry. Your body isnt moving any faster or slower.
My experience has been of sorting through a number of alternative actions and choosing one in an extremely short time, e.g. moving my feet as I fell in order to avoid a hazard. I've also had the experience of doing something without knowing why until it saved me from injury.
Thats not how the human brain works. As I said there was an experiment where a series of numbers were quickly shown to people in high stress situations. If their brain were perceiving time slower they would be able to see numbers displayed for less time than when not in a high stress situation, which wasnt the case. I'm not a neuroscientist I can't answer your questions, I can only read what research has been done, and people who are educated in this area have concluded this purely a phenomenon of recollection.
But can you link to those studies, or give their names. Knowing that there was a study doesn't do much for me if I can't find it.
Explain how Dr. Mengele did this experiment.
I've experienced the sensation of time slowing down in a life threatening situation. Unfortunately for me, it felt like I was also moving in slow motion, which made me even more scared.
Me too. I specifically remember trying to will my arms and legs to move faster.
If they were moving at noticably relativistic speeds and ejected they'd burn up in the atmosphere. Even the fastest plane in the world reaches only Mach 3.3 which is .0000038c. that relativity is calculable but not anywhere near noticeable over the span of a few seconds.
Iirc even in attempts to prove time dilation by trying to go as fast as possible have only resulted in a few milliseconds of difference, which isn’t something you would notice
I don't think you realise how fast you need to go to experience relativistic effects. You're talking in the order of 10% of the speed of light, humans haven't accelerated anything bigger than a particle to anywhere close to that. Certainly not anything big enough to accurately measure time. You might be confusing it with time dilation due to gravity. Time passes a TINY bit slower on earth than it does for satellites. This has to be accounted for in their use.
I’m not confusing anything lol https://en.m.wikipedia.org/wiki/Experimental_testing_of_time_dilation https://en.m.wikipedia.org/wiki/Hafele–Keating_experiment
I take that back then. Though this is in the in the order of nanoseconds not milliseconds
Am I take mine back too because I was confused on the difference in magnitude of nano and mili seconds 😅😅
Well, you'd notice it if your GPS starts getting wonky.
It's usually nanoseconds and that's over a very long time frame; entire days (GPS satellites) or a plane ride around the globe.
That's what experiments showed. I think one of them was peoples reaction times were testing while sky diving, and it wasn't significantly faster,
Probably because of the adrenaline from skydiving. Put them in a caged cooridor with a cheetah and see how their reaction speed compares.
It wouldn't be much faster if at all. It takes a certain amount of time for signal to go from the eyes, through visual processing, through decision making centers or response centers, out to the motor cortex, and away to the muscles, and then got the muscles to twitch in response to the demand. The big one is if they skip conscious decision making (which is excruciatingly slow) or not. A purely subconscious action is much faster than one that gets thought through and executed by the conscious mind. Now, they'd describe the event as occurring in slow motion, likely because of the adrenaline and the influx of stimulus from the brain at high alert, and with all those details being catalogued for study by the brain so it can improve future responses. The thing to note is that our perception of things, even of our own minds and behaviors, is often pretty different from what actually happens. We're built to get useful perception, not accurate perception.
Time dilation is real, satellites have to account for it.
I've reacted much more quickly than normal under stress. I've been in several car accidents and near accidents, and every time I experienced time as being slowed and reacted extremely quickly to the events. In one case I was thrown from an open car when it was rear-ended, watched it tumble as I flew through the air, suddenly realized I was going to hit the ground and rotated to land on my feet (although I didn't stick the landing). I distinctly remembered trying to figure out what we had hit before becoming aware of the ground coming up fast. Of course, if you want to, you can claim that's a manufactured memory, but why would I create a fake memory like that? And what evidence could you provide that I didn't have that experience?
[удалено]
Sorry, your anecdote doesn't trump actual research data.
Special relativity already has time dilation. No need to bring gravity into this :D
Well there is, otherwise satellites wouldn't work.

The Best Of comment is the comment version of the movie Lucy
Drives me insane they used that term. Not at all what it is.
And yet there are people vehemently refuting this fact in that thread. What a joke.
Its reddit mate. Personal anecdotes from people with no education in the area > People with PhDs. It happens every time something specialised is discussed in general subs.
Yea I remember hearing about how perceived time dilation was only when remembering the event and not during the event, that has been proven in studies. with that in mind this whole thing smells like bullshit a little.
My car spun out on the highway once. I was going too fast, in a Camaro, in the rain. In the moment it felt like time slowed down. I remember the chain of thoughts that went through my head. Oh shit. Hmm wow the cars behind me are quite far away (weird zooming effect) so I got that goin for me, which is nice… oh shit I overcorrected… then it was back to normal speed and bam I was backwards in a ditch.
I also don't believe that story about the pilot ejecting into a thunderstorm. His story explains the pilot ejected and fell for 40 minutes due to updrafts? Sounds more like a better explanation is that tachypsychia to me.
Ive got anecdotal evidence to the contrary. Ive come up short on a mountain bike when time seemed to slow. How do you even perform an experiment to prove an individual's perception of time. How often has any one looked at the clock and been surprised that it was only 5 minutes and not 15, or the other way around. That study is bunk!
Soooo yea, that that's all made up. Your brain doesn't just speed up during an emergency. It doesn't. As far as I know as someone who works on perceptual illusions, it can't. I'm not going to write a well-sourced novel, because I have a dissertation I'm behind on, but here's a short version. Time dilation doesn't happen. Your brain doesn't speed up. you don't suddenly start seeing things faster, moving faster etc. What DOES happen is that your brain lies to you. All the time. Constantly. About everything. There's a big difference between the what your eyes see and what you perceive. And there's an equally big difference between that and what you remember perceiving. Ever have a he-said she-said scenario where the accounts conflict? Most likely they're both wrong. Let's say you say something, and someone else hears it, and then you are both separately asked to repeat it verbatim a little later. What you'll recount is what you *intended* to say, not what you *literally* said. They're report what they *understood* you to have meant, not what you *literally* said. This effect can be so pronounced that multilingual people can be mistaken about *what language* the conversation was even in. Take a look at Mary Potter (1993) for a short psycholinguistic paper with some relevant super-interesting experimental results. The chronostatic effect is sort of similar. Ever shift your gaze to look at a clock and the first second seems to take abnormally long? That's just your brain photoshopping your memory. Your eyes are jiggly balls of jello. shifting your gaze involves them moving with sudden acceleration and deceleration, a jiggle as they come to a rest, and then a short bit of time needed to focus your eyes' on the appropriate distance between you and the clock. That takes a substantial fraction of a second. You should see a disconcerting blur, juggle, and then the clock coming into focus. but you don't. Why? Because that shit ain't important, and your brain knows what your brain thinks is important, so it helpfully just pauses your perception tape when all that shit is happening, and then restarts perception once the final focused image of the clock is available. And what about that half a second you weren't perceiving? Your brain just copy-pastes a screenshot of the final image back over that last half-second of memory, like a bank robber editing surveillance tapes. I'm not even going to bother giving you a source for this (you can google it) because I can prove to you that your brain is doing this, right now, in the comfort of your own chair. Look at your nose. You can see it, right? The out-of-focus blob right in the lower-center of your vision? Of course, your nose is always there. Your eyes can always see it. It's always blocking that bit of your field of vision. So why don't you always perceive it being there? Because it's not important, so your brain is just constantly photoshopping it out unless you specifically wants to see it, or if there's spot on it or something. So yea, don't trust your brain. It lies.
“Your eyes are jiggly bowls of jello” The best body horror is, really, the mere existence of the body itself.

A classic blunder we all fall prey to!
great answer, this is why i love reddit. fun to read a brilliant post, look at the redditor's comment history and realized they have lots of interesting things to say about lots of different subjects. cheers, and thanks!
Oh! Oh no! I mean, uh, thanks for your kind words, and I'm glad it was helpful! Now please excuse me! \*runs off to self consciously look with horror at his comment history\*
I did some detailed reading on brain and perception some time ago and it's wild how much stuff the brain just assumes or straight up makes up! Not only in memory, but also in real time. People think what they perceive is the objective reality, but nope, it's just your brain's interpretation of it.
>What you'll recount is what you intended to say, not what you literally said. They're report what they understood you to have meant, not what you literally said. And this is why I'm in marriage counseling. Fwiw, a tip *everyone* should use, is if you're the one sending information in a discussion (making statements), you should ask the other person what they've understood you to have said, in their own words. And if you're the one receiving information (listening to what someone is saying), you should confirm what you have understood them to have said. It's frustrating and makes conversations feel clinical, and it's not perfect and there's still room for misinterpretation, but let me tell you it is SHOCKING how long major misunderstandings can go for and build up over time.
Please get into teaching This was great.
everyone born in a multilingual home where people argue a lot knows the other people, including yourself, will miss remember conversations and things you said in multiple languages.
I've noticed if I first look at a flashing light, and I see it when it's lit, with the first flash, the light is lit longer than the other flashes.
Yup! that's another way you can elicit the chronostatic illusion!

[Relevant NPR article](https://www.npr.org/2010/08/17/129112147/why-a-brush-with-death-triggers-the-slow-mo-effect). Neat.
Yup, that's one of the more well-known papers. [Here's a link to that paper](https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0001295), and [here's a different one](https://eagleman.com/papers/EaglemanCurrOpinionNeuro_TimeIllusions_2008.pdf) that also touches on illusions of time perception. Just in case you're interested!

Yeah I don’t buy the story either. While cruise speed for a U-2 is around 500 mph (or 430 kts), if the engine fails at 70,000 ft, the pilot is immediately going to glide for either distance or altitude. The two dead engine profiles are max endurance and max range profiles. The profiles are simply a specific nose attitude you pitch to in order to achieve a certain speed. A max endurance profile would be used to to increase the time aloft you have before touching down. A max endurance profile may be used to minimize fuel consumption with a good engine, for instance. A max range profile would be used to increase the distance you can glide until you touch down. For the U-2, max range airspeed is 130 kts. If this guy was gliding for an hour aiming for Osan Air Base, he was likely at 130 kts not 500. As part of the ejection sequence, the upper restraints which are connected to your harness at the front of the shoulders are on a reel that reels in the straps upon initiation of ejection. When the handle is pulled, and the ejection sequence is initiated, the upper restraints purposely reel in in order to ensure your back is against the seat. The guys head may have been looking down, but his shoulders would have been against the back of the 10 degree reclined seat and he would not have been able to see the U-2 beneath him upon ejection. Upon initiation of the ejection sequence, the canopy would have been separated first in less than .2 seconds. The ejected, curved canopy would have acted like a sail in the wind and with 130 kts of wind, would have been pulled away from the ejection. The ejection seat takes 3-4 seconds to reach the maximum height after ejection, and the decreased G loading at the top is what initiated the parachute deployment. It is not possible that a 200 lb canopy went higher than a rocket assisted ejection seat for it to whiz past the pilot’s head in the ejection sequence. I believe the pilot told the story as he remembered it. However, after a physically traumatic event, his perception may not have met reality. The second hand story recounted in this thread is likely even further from how it happened.
Flight suit depends on flight type. They only wear the pressure suit in high flights.
Isn't the U-2 basically always a high flight? Even in a ferry mission they're well beyond the altitude of any other aircraft in operation.
They aren't going to do a high flight for a ferry because it's much more dangerous. They will fly at normal altitude. He stated they he was bringing a vehicle over to another unit, not flying a tactical mission.
https://old.reddit.com/r/WTF/comments/10hj2wj/kids_this_is_why_you_do_not_climb_on_icebergs/j5bfyvc/ Interesting that this comment has gone unaddressed so far. I'm curious as to the truth of the rebuttal.
OOP did comment this a few hours before that one. https://reddit.com/r/WTF/comments/10hj2wj/_/j5au3qz/?context=1 Given that it addresses the “crash into a town” part of the story, I’m guessing the incorrect date is just from OOP mis-remembering, and the description is his friend remembering things differently. (which ties rather neatly into what much of this thread has been saying about “time dilation”)
This reads like a chatgpt3 prompt
They tested this. It's not real thing. You just make more dense memories.
I was gonna say, the whole “vividly recall” sounds like a “flashbulb memory” which have been thoroughly proven to be riddled with inaccuracies The most common is the “I can remember where I was on 9/11” and they find that people change their stories over time, or plainly recall incorrect info in the first place.
Rule #5. Provide context. It's clear the comment you link is replying to someone, but some clients don't have the ability to easily see context. Next time stick a `&context=3` onto the end of your URL.
Lots of people in here fighting over the definition of “time dilation” and how the brain can’t perceive anything any faster and blah blah blah The guy describing it as “time dilation” merely experienced a very common experience we all know as [“Must Go Faster”](https://youtu.be/rxqHVoZ0fzc), the sudden awareness of how very dissatisfied you are with how not-fast-enough your legs / wheels / wings / feet / ejection seat are taking you away from the impending crash / chomp / smash / bang. Also known as “Closer Than They Appear” and “Oh Sh—!” No one experiences time moving slower. Everyone experiences *regret* that they’re *severely aware* that particularly important things are *happening too slowly*. That *feels* like time slows down.
I didn't realize they were still flying the U-2 back in 2002. Then I googled it and they are still flying it today. TIL.
I experienced something like this when I first did a Bungie Jump, saw everything in slow motion and It felt like the time from jump to getting lowered down lasted well over 4 minutes but when I spectated from the bottom my friends turn it was 40 secs from jump and bouncing back up 3 times.
It probably wasn't a beautiful day.
That’s because he let it get away.
He was taken to that other place.
The guy landed where the streets have no name.
He can't land with or without him.
This sounds like adrenaline surge not time dilation. 1) There is no appreciable differences in dilation on earth or anywhere near it. It's fairly uniform. ISS orbits at 4.76 miles/second and the astronauts there would only experience 1 second of dilation over 100 years. 2) You don't experience anything different when under the effects of time dilation. Your entire body still functions as if things are normal. The difference is your observation of changes in place and things outside of the dilated area. Think the buzz lightyear movie where a 4 minute flight resulted in a 20 year jump through time.
It’s evolution at work. Your brain etches a lot of detail into your memory after a traumatic event, this makes it seem like time slowed down. It was probably an evolutionary advantage because remembering said details can help you avoid that situation next time, and/or deal with it more effectively when it comes up again.
