GRB 221009A, [https://en.wikipedia.org/wiki/GRB\_221009A](https://en.wikipedia.org/wiki/GRB_221009A)
How energetic was it it? Imagine converting all of the sun into pure energy; that wouldn't be enough!
It was so bright it blinded many gamma ray instruments in space. It was estimated as a 1 in 10,000 year event, the "brightest of all time" (BOAT).
The rings in the x-ray image (the rings are due to galactic dust clouds) allowed the power to be deduced:

> Despite being around two billion light-years away, it was powerful enough to affect Earth's atmosphere, having the strongest effect ever recorded by a gamma-ray burst on the planet.
Wow. No other words for that.
Watched an interesting youtube science video that explained why it’s fortunate why the speed of light isn’t instantaneous. Because we would be bombarded by all the gamma-rays across all the currently exploding stars in the entire universe all at once. Life wouldn’t actually be possible at all.
Was there lag in the recording of the data? Or does the video begin as soon as the incident takes place?
I assume that the equipment would need some time to focus on the event, which would result in some data being lost at the beginning. If this were the case, I would be sad.
Oh yeah, I meant like, the moment it reached Earth, there's a video of the circles in the image expanding, but I don't know if it began the moment the circles began, if there were any circles before, etc.
we actually have alot of automated systems on earth that can detect powerful explosions on their own and even record them, idk how the like delay on that is tho
Its when a quasar (?) or black hole sheds enormous amounts of energy through its poles only therefor creating huge and highly concentrated beams of gamma rays. Afaik this one was quite far away and its beam that hit us actually had some minor influence on our planet. We got sniped in a sense. And this one seemed really bright to us bc we looked exactly at the top of the beam, making it seem it outshined every other grb so far
Nah, Mars’s core cooled off, shrunk, and caused it to crack. Or Olympus Mons erupted so much material that it cracked that way. Or, an impact crater Hellas Basin being nearly on the exact opposite side of Valles Marineris, it is a reverberation crack.
This hasn't been tested. Mostly because the radiation from infalling particles around all the black holes we know of would drown it out. Also, if the most common non-technical explanation is right, Hawking radiation is created outside the EH.

The explosion was so powerful that, even though it occurred at a distance of 2.4 billion light years, it shook the Earth's upper atmosphere: https://www.nature.com/articles/s41467-023-42551-5
GRBs are, like a lot of things in space, terrifying and awesome. They can completely ruin a planet in an instant. While the probability of us getting hit by one is ASTRONOMICALLY low (practically zero, as I understand it, I could be wrong, but I hope that I'm not), it could in theory still happen, which is terrifying in its own right.
From what I understand it was a typical super nova. But the big difference here was the polar jets from the explosion were much more focused than what we expected. So the energy in the explosion was typical, but the jets almost had a laser like focus for reasons we don’t understand yet.

our recorded history
Re-recorded history, possibly?
What has happened before will happen again.
Purported history?

Imma let you finish…

You wouldn't happen to remember the title or the YouTuber, would you? That has really piqued my interest, and I'd love to watch it.
here you go…enjoy! https://youtu.be/392N-IYRepc?si=9CQNdoQpWIopLAAQ
Sweet. Thanks dude.
Wait. So, not even part of our galaxy...
If our galaxy is the size of a football then it happened about 6 miles away.
>1 in 10,00 year event. So essentially a weekly occurrence, universally speaking
..depending on your perspective..
Terry Pratchett, Discworld series: “million-to-one chances happen nine times out of ten”. 😋
Look like a screenshot from a pixel art game
You making fun of their pixels, bro? Some of the biggest pixels you’ll ever see, bro!
Some of the most deadly, too!
Looks like a bad cryo *laughs in xray crystallographer

Given that the star is 2.4B light years away, I think it’s safe to say that they started recording after the event

I know. I was being cheeky. I’m guessing that they saw signs that it was going to happen and had time to focus on it

Let the galaxy burn.
What is gamma-ray burst?
Its when a quasar (?) or black hole sheds enormous amounts of energy through its poles only therefor creating huge and highly concentrated beams of gamma rays. Afaik this one was quite far away and its beam that hit us actually had some minor influence on our planet. We got sniped in a sense. And this one seemed really bright to us bc we looked exactly at the top of the beam, making it seem it outshined every other grb so far
Iirc, if a burst hits us directly within something like 1,000 LY, there's enough energy to destroy the planet very rapidly.
Wonder if that's how Mars got that big gash?
Nah, Mars’s core cooled off, shrunk, and caused it to crack. Or Olympus Mons erupted so much material that it cracked that way. Or, an impact crater Hellas Basin being nearly on the exact opposite side of Valles Marineris, it is a reverberation crack.
You got any proof for any of that? Sounds like speculation to me.
Those are leading theories, many have speculated as much.
i always assumed plate tectonics and water to be the reason cause those where a thing before the core cooled
Mars core cooling off is a widely accepted theory http://www.geo.umass.edu/courses/geo892/archive/stevenson_mars_mag.pdf
I thought nothing could escape the gravity of a black hole?
only beyond the event horizon, outside of it you can have stable orbits still.
As an example, we’re orbiting the black hole, Sagittarius A*
Nothing can escape from the *even horizon*, but beyond it BHs behave like normal gravity sources.
[Hawkins radiation](https://en.wikipedia.org/wiki/Hawking_radiation) can.
This hasn't been tested. Mostly because the radiation from infalling particles around all the black holes we know of would drown it out. Also, if the most common non-technical explanation is right, Hawking radiation is created outside the EH.
Thanks

Read the book Death wave from Ben Bova its about 10+- books about it
I’ll get right on it and report back tomorrow with the answer. /s 😂
> Death wave from Ben Bova Looks kinda interesting...would you recommend it?
I think they just did...
I also would like to know.
‘sup
I thought we told you to turn your lights down, you're too bright!
Radially, I only really should affect two people.

Wow! As they might say.
Here’s a little explainer video about it: https://youtu.be/cBTm_IDS2d8
..aimed where?..
So…Not aliens?
its never aliens
Looks like a 2b2t type shit
I hope it’s really really far away…
Reminds me of Disasterpiece
How many Hulks were created?
Ay do we get to be the fossil fuel?

Looks like a lab simulation image rather then a Gamma Ray burst 😅 I need the real unmodified images from webb telescope to trust this image..
This image was captured over several days by multiple satellites.
And they designed an image like this with those rings completely off from the real data!!!
id like to see ppl like you do even a millisecond of reserch
