| It would contiune until another force acted upon it. It would continue at speed, for an infinite amount of time, or until the above stated event would occur. No question is stupid only the ones that are unasked, horrible cliche I know. |

Could you even shoot the gun? The sparts used to ignite the gunpowder would need oxygen to last and there is no oxygen in space.....or air(which is almost the same thing) So...could it even shoot? |

| Total void in space doesn't really exist as there still is very dilluted gases (mostly hydrogen). So there still is friction. Now, as there is most likely to be another body that will interact with the bullet, I don't think that the friction force becomes revelant. |

You can shoot a gun in space if the powder has it[s own oxidizer to make it burn. A bullet fired in space will continue to travel at is' initial velocity and is sybject to gravity and fruiction. Still it ouwld lake a very long time for the bullet to change velocity unless it was acted on.  |

The net momentum of a system will NEVER change unless acted on by an external force. Given any sufficiently long time, this still holds true.
