What would happen if a bullet was shot in space?

Some people may think that they can't shoot in space because there is no oxygen in space. In fact, the bullet contains its own oxidant and does not need oxygen to help. If the bomb really needs to be launched by the surrounding oxygen, it will not be able to shoot any bullet except the toy gun. So in space, the gun can be shot normally, so what happens after shooting?

The first combustion smoke will be spherical diffusion, rather than on the earth as the wind wave disturbance. When a bullet is launched, it will move along a straight line. Because there are hardly any other substances in space, the bullet will continue to move down until it hits a planet or a space rock. Of course, this possibility is extremely small. It can be said that there is hardly any reason, because the speed of the bullet is too slow to reach another planet, almost theoretically. Of course, if we are to a planet like Jupiter, shot, even you can no longer poor, as long as the general aim, Jupiter's great gravity will capture the bullet, let it along the curved path shot into Jupiter's atmosphere, the speed will be increased to 60 times the muzzle, and then melt Jupiter in the sky.

If the muzzle velocity is 1000 meters per second, because the universe is expanding, a calculation, from the muzzle of about 40 thousand to 50 thousand light-years, the expansion speed of the bullet is approximately equal to 1000 m / s, which means that the bullet will never catch up with the material here. But space is not an absolute vacuum. There will still be very thin atoms. Every bullet will cause resistance to the bullet, so the bullet will stop after 10 million years.

After the bullet said you, the bullet does not matter fate, after all, it has no life. But when you shoot in space, if you don't have any other devices to help, you will go back in the opposite direction of the bullet. The quality of a rifle bullet is about 5 to 10 grams. If your weight is 70 kilograms, the bullet will be 10 centimeters per second according to 7 grams. It will drift 8640 meters every day in space. If just in front of the earth, you will become a meteor, to bring good wishes for the people; if you just in front of the moon, you will meet with the goddess of the moon in 120 years, but some fast speed, is about 2400 meters per second, even some can not afford Dan Chang oh.
