I was playing ghosts a few minutes ago and when it got to the part where you shoot guns in open space, I started laughing at the absurdity of it. There are many people on here much smarter than me, so I thought it would be fun to make a thread about how a gun would function in space, how it could function in space and what would happen if you were to use a gun in space.

as long as u shoot it in glass u ok

They are literally shooting in open space. Shooting each other while floating around in space suits.

Guns don't need oxygen to function, everything you need to detonate a round is inside the casing. It cotains it's own oxidizer (saltpeter or niter). A gun would shoot in space and because there's nothing to slow it down (no gravity or atmosphere) it would probably travel forever until it hit something.

Like Air's mom, modern guns are tight little packages. It's almost like they have their own airtight atmosphere inside of them.
I don't take a gun to bed with me, just Air's mom.

Wait...everyone claims they have slept with my mom tho, so I don't think she is a "tight little package".

I was talking about her bum. She only lets me in there. Tight little package.

Ohhh I see.

Wouldn't you be sent at the same velocity in the opposite direction if you fired a gun in space because no gravity and no air so no drag?

Mass is energy, and the energy it takes from a gun to send a bullet out of the barrel is not enough to move you that fast (as fast as it sends the bullet) as well. This is because you are much more massive than a bullet (and the force launching the bullet is amplified because the barrel of the gun concentrates energy right onto it). In zero gravity, shooting a gun WOULD send you in the opposite direction; it just wouldn't be all that much and the amount depends on the gun, your weight, what you're wearing, etc.
I could see a big ass sniper rifle giving you a pretty good jolt of motion, just nothing close to what it gives the little bullet.
Shameless plug: Kerbal Space Program is an awesome game to watch videos of or play to learn about energy, mass, gravity, thrust, etc. :)

Look up Space Engineers

These physics equations are easy, might actually try them. LOL or not: http://www.1728.org/energy.htm (http://www.1728.org/energy.htm)
Using a weight of 8 grams (for a 9mm bullet), with a speed of about 340m/s as it leaves the gun, that gives it ~460 joules of energy. That 460 joules of energy is enough to push a 75kg person back at 12km/h (a bit faster than average walking speed). You could say the arm will absorb some of the shock but there is no ground to shift that shock into, so you will take all that 460 joules as kinetic energy, however some of it will likely cause you to spin so the final speed will be lower.
Another way to think of it is if you burnt 1kg of wood, one inside a large bottle, another in a huge room. The same amount of energy is released in both cases, but the smaller area has the energy more concentrated, so the bottle will end up much hotter than the large room. Same why the bullet will go faster than you with the same energy.
Gunpowder doesn't need air to burn, it already has a very strong oxidant in it. The activation energy to trigger the burning reaction is fairly low, so don't throw bullets hard or drop kegs of gunpowder lol.
Basic gunpowder formula and reaction is
2 KNO3 + S + 3 C → K2S + N2 + 3 CO2.
Basically this is two parts potassium nitrate, one part sulphur and three parts pure carbon (from charcoal). It burns into potassium sulfide, nitrogen gas and carbon dioxide.
Also hello NSA spies, who are probably reading this now it mentions gunpowder formula, guns, space, air's mum, packages and who knows what other key words 8)

ALLAHU AKBAR! AMERICA WILL BURN! BOOM BOOM BANG BANG!

You guys are dorks.

im cool tho

Ammo is fairly safe...Even if you throw a bullet really hard at a wall, it won't go off, even if you hit the primer. You need a firing pin to detonate that primer or lots of heat.
Fun fact: I remember sticking .22 rounds face down in the dirt and pouring alcohol on them, blazing dat shit and making them shoot...I had a weird childhood. I also tried it with a 9mm round but it didn't work for some reason.

12km/h is 3.33 m/s, which isn't a lot in space. The ISS is travelling at about 7800m/s.
If you were slowly floating away from the ISS and needed to get back, you could probably use a gun to propel you back. Or a jetpack, whatever.

No problem for you with those tacos then ;)

I just finished the game, it was a lot more fun than some of the others. I loved the silly plot and ridiculous settings. Game play was what you would expect and the graphics were top notch. Overall out of cod games I give it a 10 and out of video games in general I give it a 7.5 , maybe 8. Only thing I don't like is that you don't get the same sort of guide map like in other cod games that shows you where to go.

I bought it on Steam and the multiplayer wasn't bad. It's been a while since i've played a retarded fast paced FPS like COD and it was pretty refreshing :D
