CAN YOU SHOOT A GUN IN THE SPACE?

Shooting a gun in space is possible. Clear that there will be no fire, because there is no oxygen, but the mechanics of a weapon works equally well in the ground and space. However, if there is no fire, what happens?

It is rather complicated to explain:

The orbit of a body around another in space is as everyone knows the effect of gravity; when a body that is moving in a certain direction attracts another by gravity, this is directed toward him permanently, i.e. that when an object orbiting another in reality it is doing is falling steadily; is able to stay so thanks to the normal acceleration, parallel to the gravitational force.

On a planet like Earth, with the force of gravity that has, this only has effect on certain bodies located some distance and to move at a certain speed, but in a small satellite as it is the Moon, the same effect can be a powerful enough weapon firing. i.e., if you shot at the moon with a weapon that can reach certain speed (in this case 1600 m/s), the bullet would do an orbiting satellite, and if you don't move, this would end up hitting you in the back.

It can also happen that the third Newton law establishes that the force exerted on the bullet imparting a force equal and opposite on the gun and due to that is holding the weapon… and with no place on which to rely, you will begin to move rearward (although you wouldn't have no way of knowing that you are moving). If the bullet out of the barrel of the gun to 1,000 meters per second, you would travel in opposite direction to only a few centimeters per second, due to the difference in mass between the bullet and the person who shot it is enormous.

As the universe expands to a much greater speed to which the bullet could travel, therefore the bullet could never come to any side. The same would happen with you, that after shooting the weapon you will displace in the opposite direction to the bullet at a lower speed. This means that in relation to your speed the universe would expand faster, therefore neither should you go to any side.
