It's not because of gravity there Bill Nye. It's called oxygen. Gunpowder + spark needs flame to ignite, generating the pressure to send the projectile down the barrel. The question is, can bullet casings hold enough oxygen to provide enough air to cause a flame? Have you ever even fired real gun buddy? Obviously not. Well, your probably too young or some other factor.
Wouldn't gravity stop a speeding commit or asteroid then too?
I don't mean to harp on you man but it's very easy to get real info if you don't know instead of posting what you THINK is the right answer.
sorry "JEDI MASTER YODA" you watch to much star wars lol no offence
The oxygen is contained within the gunpowder, so it would work, not the same as on earth but it would fire, I still think there would be a muzzle flash just probably less than normal.
Yes you can use a gun in space. Yes it will fire. The Primer/Blast-cap fires from a CHEMICAL reaction. The real question is what about compression's?
Sorry for the edit forgot to add the link Duhuh!
There would be no muzzle flash (when refering to muzzle flash as the fancy flash appearing outside of a gun barrel), simply because of there being no air (or oxygen) in that place. If a gun can be fired then by the very nature of the event there will be a minor burst of light within the barrel.
As for the rest, it's arbritrary. The guns presented as being used in space could in theory have been adapted or optimised - as could be done for any environment. It's easier to think about the basics.
Sound doesn't travel through a vacuum, light does but requires a mass to be absorbed and therefore for it's path to be visible.
The laws of gravity apply everywhere, gravity is a universal constant. The force of gravity, however (which is where people are getting misunderstood) is dependent on mass (as per the laws) and so in space (by it's very name) there's not as much mass to pull on matter. If you're in deep space between solar systems (or even more incredibly between galaxies) you'll float around and feel no sense of pull or of "gravitation". If you're just outside the Earth's atmosphere, you'll basically head towards Earth, accelerating as you do so, until resisting forces slow you or combust you.
I found this thread fun, unfortunately as with most discussion threads, the disagreements turn to slander. Perhaps, that though is part of the process of threads, communication and discussion on this forum.
