I've heard too many people saying "Yeah u cnont fire a gun in spaec gos no oxygen/overheatlolol" and such.
I'm here to educate atleast some of you why firearms would work in space.
First they work much better than on earth: the bullet will go straight and true cause there's no gravity or wind to alter it's course. It will also go faster and not stop unless it hits something cause there's no air to give it any friction. Thanks to recoil, so will you.
Now for misconseptions
[B]Guns Can't Fire In Space Cause There Is No Oxygen To Let Gunpowder Burn[/B]
This is false, cause since the dawn of time gunpowder has had oxydiser in it.
Gunpowder is made of Charcoal, Sulphul and Potassium Nitrate
Potassium nitrate contains the oxygen, it's formula is KNO3.
Think about it, if gunpowder dind't contain any oxygen, how would it fire from a completely sealed cartridge?
[B]Guns Can't Fire In Space Cause They Will Overheat[/B]
Issue with this is that people assume there's no air in space to take the heat away.
There are 3 types of heat transfer:
[quote]
* Convection transfers heat by moving matter, usually a gas, around. A fan blowing on you is convective cooling.
* Diffusion is the transfer of heat through contact, like putting your hand on an ice cube.
* Radiative transfer uses photons (light or infrared photons) to transfer heat.

Space is vacuum and does not indeed have any air. Space is temperatureless. But all objects that don't recive any radiation for stars and such get colder than a witches tit. In fact they can get as cold as 3 degrees above absolute zero colder-than-a-witches-tit.
Reason for that is beacuse the only way for heat to transfer is via radiation, it radiates into various wavelenghts, mainly infrared. For human it would take some hours to start completely and throughoutly freezing, but a gun is much smaller and not made of metal, if it's a proper one.
[quote= A dude from NASA: Dr. Eberhard Moebius] Have you ever stood in front of a campfire on a very cold winter night? While facing the fire you may feel roasted in your face, while your back feels frigid. The fire radiates heat at you, and your back radiates heat into the cold night. Of course, the cold air around you plays a role, but if there is no wind, the major heat exchange is radiation.
In space this is turned to the extreme. Without any star or planet nearby the temperature of space (as defined by radiation) is 3 K (-270 centigrade), the temperature of the ubiquitous background radiation from the Big Bang, i.e. extremely cold indeed. A spacecraft is roasted on the side that faces the sun and very effectively cooled on the opposite side. [/quote]
Now you know he is right, cause he works for NASA and his name is motherfucking Moebius.
for further proof: during the moons day circle the moon reaches temperatures of 107C during day and cools down to -157C during night cause there's no atmosphere to bounce the heat back to keep it from cooling.
The problem with overheating is true when you are trying to fire it when exposed to sunlight, the radiation will be so itense that the gun will heat up to temperatures where the ammo will go off in the magazine, effectively turning a firearm into a grenade. The problem also persist if you want to do sustained fire. I don't think pulling off 3 or so shots would cause any significant issues.
Also when you are not in the way of any radiation the gun will cool down, and if you're firing something like Glock which is mainly made from some plastic shit, it'll be in a world of pain cause when cooling, stuff also shrinks and metals and plastics srhink differently. In the end the gun would simply fracture.
[B]The Lubrication Issue[/B]
That's one issue that fucks up things in long term: On earth guns are lubricated cause there's air between the parts that keeps the friction resistance lower than it would in space, in space there is no air to do that.
Also all regular lubrication vaporizes without atmosphere. This causes a bigger problem cause metal works differently in space. If two pieces of metal that don't have a layer of oxyde on them are put together, they instantly and perfectly join together.
So once that oxydised layer wears off, the parts will join and the gun will simply no longer work. ever.
Soviets sent some armed spacestations and conducted some experiments on a 23mm antiaircraft gun.
It worked well only they had to use silicone balls or something and lubricate the weapon before each shot.
So there, guns can work perfectly well in space when they don't freeze to pieces, explode or turn into one piece metal.
[B]The Recoil As Explained By Swebonny When Firing A 5.56 Nato[/B]
[QUOTE=Swebonny;27244213]To prove it I'm just going to show the things ThePuska talked about.
The momentum created by a bullet with the weight 5 grams and the velocity 1000 m/s is only 5 kgm/s.
p = mv -> 0.005 * 1000 = 5 kgm/s.
Now what speed can that bullet give a person in space wearing an EMU suit?
Suit weight = 115 kg, add the person, let's say 80 kg = 195 kg.
Now how much speed will 5 kgm/s give an 195 kg heavy astronaut?
5 kgm/s = 195 * V
V = 5/195 = 0.0256 m/s
So, not really sending you deep deep into space, but giving you a slight push.
2.5 cm / s is still noticeable.[/QUOTE]
If you manage to prove me wrong, I'll happily make changes.
Thanks for setting me straight on this, I was jetting off into orbit tomorrow and was up in the air as to whether or not to take my gun. Cheers.
There would be gravity unless in totally 'Middle of fucking nowhere' space.
i have a better idea: lets keep killing each other to the earth and keep space peaceful
[QUOTE=RubberFruit;27238566]There would be gravity unless in totally 'Middle of fucking nowhere' space.[/QUOTE]
yeah, gravity is just such a weak force that being far away from stuff hardly effects it. yet space is rather big so when the bullet flies 100 million km you'd see the impact of gravity
They work, but they don't work well is my understanding.
Phone NASA and they'll launch a terrorist up there within the next week.

So how long does it take for the preparation process between each shot?
I'm pretty sure blowback action guns won't work.
What about pumpaction Supersoakers?
You'd also have to consider recoil in zero g.
You fire at someone and you're gonna end up flying backwards with no way of stopping unless you shoot the other way :v:

Let's consider a hypothetical part of space, where object with gravity is hundreds of lightyears away.
It's like asteroids:
Firing will push you back so you have to waste precious brass by firing behind you to go back again
Guns in space :smug: i'm in!

[QUOTE]Some sources claim that on January 24, 1975 (after the station was ordered to deorbit) trials of the on-board 23 mm Nudelmann aircraft cannon (other sources say it was a Nudelmann NR-30 30 mm gun) were conducted with positive results at ranges from 500 m to 3000 m.[1] Cosmonauts had confirmed that a target satellite was destroyed in the test.[citation needed] Firings were conducted in the direction opposite to the station's velocity vector, in order to shorten the "orbital life" of the cannon's shells. A total of three firings were conducted during the flight of the Salyut 3.[/QUOTE]
And there we have it. The answer.

Gravity is everywhere, any atom attracts every other atome, only the distance makes it almost 0, but it is still there.

Well perhaps your time is better spent at NASA and not on FP?
This is stupid, realistically, what use will we have a gun for in space?
There's "no" gravity in space so we will all just bounce around and float. By the time someone threatens to hit you, you'd be in your spaceship or rocket and be gone already.
Also by the time EVERYONE can just go into space for the hell of it, I'm sure we will have LASER guns.
