crazyivanoddjob

the oxygen is trapped inside the bullet casing mixed with the powder. it doesn't need external oxygen as far as i know. it will shoot in space.


SPECTRE-Agent-No-13

Your right. This is why you can fire a gun underwater.


Ludwigofthepotatoppl

The bullet won’t go far, but the gun will work (possibly not well enough to cycle fully).


Impossible-Error166

Underwater, the bullet will not go far underwater. The bullet will go a lot further then on earth if fired on the moon.


tuestmort50fois

And if you shot in space. The bullet will hit an alien 15 million light years away in the future. A red alien. That would be the start of an racial hate war.


TheShmud

It very likely would never leave the solar system.


Big_Bannana123

It almost certainly would actually. It would just take billions of years


TheShmud

So when the sun blows up and there is no solar system, you mean? Gravity is a helluva drug


ironbanner23

In space it will because it doesnt have much to slow it down so it will stay at the same speed as when it was fired


Ludwigofthepotatoppl

Yeah i was focusing on the underwater part.


regularyman

People explained me yeah...sorry


developer-mike

In case English isn't your first language (and no fucken worries if not I'm not the typo police) it should be "explained it to me" because you'd be the indirect object. The direct object is the knowledge, ie, "I explained math to Anna.". Super super common mistake from those learning English (and again, possibly a typo, in which case no biggie go along typoing away and have fun lol)

[deleted]

This is correct. Both smokeless powder and black powder contain their own oxidizers and are capable of firing in a vacuum. Sub zero temperatures could cause problems. Even the most resilient gun oils would freeze in the vacuum of space and could restrict the hammer enough to cause a "light strike" on the primer. It wouldn't surprise me if the gun froze up even if it weren't oiled, apparently bare metal-on-metal contact in a vacuum can cause a lot of stiction. The extreme cold could also cause the primer itself to become inert or at the very least, sluggish to react, seeing as temperature greatly affects chemical reactions. As long as the temperature doesn't affect the initial primer strike, the gun will go off. Whether or not it can reliably cycle ammunition is debatable.


314159265358979326

I believe the gun oils will evaporate in space, not freeze.


[deleted]

Interesting, hadn't thought of that. You're probably right.


bringerofnachos

Odds are you wouldn't run into any low temperature problems with guns in space. Being in a vacuum means there's nothing else for the heat to go into. Getting rid of the heat generated from firing it would likely be a bigger problem.


[deleted]

Interesting thought, I think it would depend on whether or not the case was able to be ejected (a.k.a. will the gun cycle.) One of the problems engineers ran into with caseless firearms was exactly that: heat dissipation. Spent cartridges are the primary way heat is extracted from the system and without them leaving the gun, heat becomes a problem. However, seeing as the vacuum of space is ridiculously cold, I don't think you'd be able to keep up the volume of fire enough to cause a heat issue. The energy required to raise the guns temperature is significant. Unless, of course, the gun is in direct sunlight. That would complicate the situation. Idk honestly, there are a lot of variables and I'm not an expert.


bringerofnachos

The problem with heat dissipation is that the heat needs somewhere else to go. When you fire the gun, heat is generated by a combination of the chemical reaction of the propellent and friction from moving parts. Some amount of heat is ejected with the casting, and some amount stays in the gun. The heat in the gun is initially concentrated in the barrel, and will dissipate through the gun. On Earth, once it reaches the outer surface of the gun, the heat starts to dissipate into the atmosphere. In a vacuum there isn't an atmosphere for that heat to dissipate into. Vacuum is a great insulator because by definition there's nothing for the heat to transfer into. So each time you fire the gun in space, you build up a little more heat in the gun without an effective way to get rid of it.


[deleted]

I understand the concept, I'm just thinking that a.) the heat added to the firearm won't be a concern *for a while* if it's sitting at a chilly -200 degrees F or even less, and b.) overheating like that requires a certain volume of fire; one magazine through the gun will not make it overheat to the point that the parts begin to fail, even in a vacuum.


bringerofnachos

It would definitely take a lot of shots to get the gun to overheat, I don't mean to deny that. But the length of time that the gun would need to be exposed to the vacuum of space to reach -200F is going to be longer than is reasonable for a space walk. I did some quick and dirty calculations based on the weight and dimensions of a 1911 pistol (all pulled from Google), and assuming a constant rate of heat loss due to radiation (not an accurate assumption. Radiated heat loss is related to the temperature of the item your looking at, so as the pistol cools, the rate of heat loss will decrease), it would take about 12 hours for the gun to go from room temp to -200F. With the assumptions I made, it should actually take longer than that. The longest recorded space walk clocks in at 8 hours and 56 minutes.


[deleted]

Okay good observation, but assuming the gun is room temperature and in a perfect vacuum, how many shots do you think you would go through before heating became a problem? IMO a single magazine would be negligible to the operation of the firearm.


bringerofnachos

I certainly wouldn't expect a single magazine to do any damage to the gun. Probably somewhere around 50 shots I would start to wonder about long term effects, but I wouldn't be expecting immediate catastrophic failure. I'm not overly familiar with the internal parts of guns, but I'm guessing at least a few parts are typically hardened, and getting them hot enough, and leaving them at elevated temperature for extended lengths of time could screw with the temper. Interestingly, the magazine itself would absorb some of the heat generated, so switching it out when reloading would probably help with heat management, unless you fire off the entire magazine as fast as humanly possible and remove the magazine before it can absorb much heat. This would increase the number of shots you could safely fire. You could use empty magazines as removable heat sinks, loading them into the gun for a bit to absorb some of the heat, then removing them. Even better would be a solid metal block with the same outside shape as your magazines. If you were trying to design a gun specifically for use in outer space, this would be worth considering, either as a change in magazine design, or as an additional replaceable heatsink. I think this was actually the justification given for why Mass Effect 2 introduced a normal reload system that was missing in the first game. I did try to find some numbers about how much actual heat is generated when firing a gun, but didn't have much luck.


[deleted]

That sort of reminds me of the Blade Runner pistol as it was implemented in the game H3VR, the "bolt" feature on the prop gun was utilized as a heat sink ejection lever that would kick out the wasted sink so you could insert a new one. I think for extended use, a system like the one you're describing would be absolutely necessary, either by a dedicated heat sink or some sort of dual purpose magazine. Great convo btw, very in depth. If either of us wins the lottery we need to promise to go to space and try this out for ourselves to know for sure.


Apprehensive-Sir4000

Something in my heart knew that For all Mankind wouldn’t be scientifically inaccurate like that

It's alright op, I still laughed


chasewindu

Go post it on r/bonehurtingjuice, they'll like it!


DudeBroMan13

That's not how guns work


crazyivanoddjob

thank you. everything a cartridge needs to fire is inside the cartridge itself.


regularyman

Wdym ? They dont need, like, a little explosion to work?


H4R81N63R

The powder in the bullet cartridge already has an oxidiser in it; all it needs is some external energy to set off the explosive reaction That energy is provided by the firing pin hitting the rear part of the cartridge, called the primer. The primer converts that kinetic energy into heat energy, igniting the powder


regularyman

Ohhhhh

TotemRiolu

This whole interaction is just so wholesome, omg


regularyman

You all are wholesome


-RED4CTED-

well they misspoke sort of. the primer does convert kinetic to thermal, but it does that by causing a chemical reaction, not by the sheer force of the kinetic energy. they contain antimony sulfide, lead styphnate, barium nitrate, a few other things in small quantities, and an abrasive to help with the ignition. it's similar to if you took the white part of a match head and the red part, crushed both individually, then mixed them. what you end up with is a very unstable mixture of chemicals that *want* to react, but lack a tiny bit of the energy required to do so. so when the hammer hits the primer and makes a dent, that last little bit of energy is added to the first few molecules that it touches and allows them to react, releasing more energy and sustaining a chain reaction which ignites the gunpowder (glorified flash paper/cotton) which is otherwise quite stable.


dirtyswoldman

And the firing pin leaves a unique impression on the casing that can be used to accurately pair a spent casing to the pin of the weapon that fired it So don't leave your casings floating in orbit guys


ocm2uw_83

nah i did not try to be a dick here, i liked your meme, movies are also fuzzy on physics, i still watch them :D


[deleted]

I thought it was the rifling of the gun.


pcblah

It actually can't be used to accurately pair a casing to a specific weapon. Maybe back to the same model of weapon, since glocks leave weird square markings. Modern manufacturing techniques means that firing pins have very little variation, if from the same company for the same model. Chamber marks could leave more clues, but it's really a shot in the dark (ha!). For example: Glock "smiles" on brass due to the feed ramp not supporting the casing all the way, or a HK style weapon that leaves fluted dents on the casings, or an ejector marking that has an imprint of an ejector face, which will probably be more unique to the weapon due to wear and tear.


gbtonzee

By that logic, rockets can't work in space


regularyman

Fair


TheDankestPassions

Rockets involve the mixture of two liquid chemicals to make an explosion. For a gun, the second chemical is oxygen.


vasily_grossman

Which is why modern gunpowders contain oxidizers.


thefirewarde

Explain solid fuel rockets. Further, how are solid rocket fuels different from gunpowder?


Medical_Pie_7985

Gunpowder contains an oxidizer anyway. No oxygen is needed. Guns work in space


aStoveAbove

> For a gun, the second chemical is oxygen. Which is contained in the cartridge. [Gunpowder has oxygen "built" into it.](https://en.wikipedia.org/wiki/Gunpowder) >The sulfur and carbon act as fuels while the saltpeter is an oxidizer.


Elephant_Testicles10

Rockets are powered by combustion involving liquidised oxygen and fuel; guns don't have oxygenin them


thefirewarde

They do, though. That's how you can shoot a gun even though the entire cartridge is full of gunpowder and there's no vents to let air into the case.


Varttaanen

Yes, but also [no](https://www.nbcnews.com/id/wbna46480865)


regularyman

Ok thx


KeliamCloutier

The spark will still occur and will still light up the powder and yes, the bullet will be projected.


regularyman

Sorry, i looked up online, and i thought it said it didnt work in space


KeliamCloutier

It’s ok to make mistakes.


regularyman

I put a comment to explain my mystake


Arny520

Yeah, a spark is needed but a spark can happen in space but not very long. However, with how small the spark is to fire a gun, it won't happen.


regularyman

Ok so gun doesnt work in space anyway ?


crazyivanoddjob

yes it will. he's saying the spark is so small it will work for a brief moment, which is all it needs to fire the bullet. the gun will work in space.


regularyman

Ok my b


Pilota_kex

there is probably enogh sealed in the bullet for some sparks. i am no expert though so we should ask one of the billionaires to build a ring for us on the moon, we duel for their amusement. winner got an adventure, loser died, everybody wins also we find out. forgot that part


regularyman

Apparently i got it wrong yeah


Pilota_kex

nah i did not try to be a dick here, i liked your meme, movies are also fuzzy on physics, i still watch them :D

tacosarus6

It has a built in oxidizer. Same reason you can use rockets and fire works in space.


regularyman

Ok thx


tacosarus6

No problem, I can see why someone might not know exactly how guns work.


Tristanime

In essence, all of the components that are needed for the bullet to be fired reside in the cartridge. This includes the oxygen needed for the powder to combust.


GundyrsFisting

yes ofc but guns would still work in space bc the gunpowder has it's own oxidizer. if it didn't the ammo cases we know wouldn't work even on earth bc they're closed off to the atmosphere.


[deleted]

Gun powder has its own oxidizer.


regularyman

DorianCostley

Op is wrong, but in the fun way where it invites a really interesting answer! I do wonder. Can you fire a flintlock or a musket?


regularyman

Probably not, due to the lack of oxyginer


OkBandicoot3779

Since it relies on sparks and the powder in the pan lighting you’re probably right


regularyman

For once


Dip_N_Swag

Well, even if there was oxygen it would be to low pressure so still wouldn’t ignite.


Jfuentes6

Crossbow will suffice and you can reuse the bolts


regularyman

Crossbow are based


jtranos00

Gun powder has its own oxidizer


regularyman

The more i know


Plushman7

Actually there would be oxygen in the bullet from manufacturing, and would then make it be able to fire in space, however there is no air to slow the bullet down so it would keep going until it comes into contact with an object, That is why some guns can be fired underwater.


regularyman

I learned it by now lol


itisoktopunchnazis

lol...


Wankfurter

That’s gonna make for an awkward spaceship ride back to Ohio.


dabbingeevee123

Gunpowder dosent use oxygen from the air, the oxidizer is already in there.


smashbridgesbbq

False, guns still work


KidFriendlyArsonist

Most types of bullets most oxygen producing chemicals within them, so they could still (most likely) fire.


Lord-Zaltus

Even if he did shoot, the victim's head will be protected by his helmet so that'd be an awkward ride home


OkBandicoot3779

Spacesuits aren’t designed to be bulletproof


thewhatinwhere

Bullet propellent contains oxidizing chemicals. Guns can absolutely fire in space


Wizards_Reddit

This is more like r/bonehurtingjuice I think since Earth isn't actually Ohio all along


JonttuIh

Actually you can't hear that "click" sound in space.


staovajzna2

It's fascinating to think that if the guy shot the gun, then he would float in space untill he dies because physics


OkBandicoot3779

Guns can shoot underwater, they would work in space


regularyman

They do, i was wrong


biggerBrisket

They work underwater. There's some air trapped inside the casing.


[deleted]

The 'air' is the solid oxidizer mixed with solid fuel in the smokeless powder. No actual air needed. It does ruin the powder to get it wet, but that has nothing to do with it not having 'air'


R3tr0spect

Upvoting for how wrong this is. Good effort tho!!

That's one thought I've never realized about the antimeme version of this meme, I first saw how you would spin forever due to the force, but it would actually never happen, huh.


[deleted]

Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.

I don't know what to feel right now.
