What Would Happen If You Shot a Gun In Space?
"Post-body-390727235039995500"> Fires can not burn in oxygen-free vacuum of space, but the weapons can shooting. Modern ammunition contains its own oxidizer, a chemical that triggered the explosion of gunpowder, and therefore the firing of a bullet, wherever you are in the universe. Atmospheric oxygen not necessary. The only difference between pulling the trigger on Earth and in space is the shape of the resulting trail of smoke. In space, "would be an expanding sphere of smoke from the tip of the barrel," said astronomer Peter Schultz of Brown University, who researches the impact craters.
The possibility of shooting space allows for all kinds of absurd scenarios. Shooting stars Imagine you are floating freely in the void between galaxies - just you, your gun and one bullet. You have two options. Or you can spend eternity trying to figure out how you got there, or you can shoot the damn cosmos. If you do the latter, Newton's third law states that the force exerted on the bullet will impart an equal and opposite force on the gun, and because it is holding the gun, you. With very few intergalactic atoms which are prepared against yourself, you will begin to move back (not that you would have no way of knowing). If the bullet leaves the barrel of the gun to 1,000 meters per second, which - because you are much more massive than it is -. He will head the other way a few centimeters per second Once fired, the bullet will go on, literally, forever. "The bullet will not stop, because the universe is expanding faster than the bullet can catch up with any serious amount of mass" to slow, said Matija Cuk, an astronomer joint appointments at Harvard University and the SETI Institute . (If the universe expands, then the one or two atoms per cubic centimeter found the bullet in the near vacuum of space would bring to a standstill after 10 million light years.) Hands to information, the universe expands at a speed of 73 kilometers per second per megaparsec (about 3 million light the average distance between galaxies years, o). According to calculations by Cuk, this means that the matter is 40,000 to 50,000 light years away from the bullet would move away from it at about the same speed at which it travels, and it would be so forever out of reach. All over the future of the universe, the bullet will catch only for atoms that are less than 40,000 years or so camera light of his gun. Speaking of you, you be bobbing through space forever, too. [Album: Visualizations of Infinity] giants shooting from the hip The weapons actually carried away into space, though not entirely vacuum between galaxies. For decades, the standard package survival for Russian cosmonauts has included a gun. Until recently, it was not any weapon, but "weapon a luxury all-in-one with three barrels and a folding stock that doubles as a shovel and contains a machete swing-out" according to space historian James Oberg. Space weapons are issued in case astronauts need a return on Earth, so they can protect themselves if emergency landing of their Soyuz spacecraft has left them abandoned in a treacherous region. But still, the cosmonauts theory could fire their weapons before landing. So what if, during a spacewalk, a cosmonaut opened fire on Jupiter? He or she should feel free to shoot from the hip. According to Robert Flack, a physicist at University College London, the huge gravitational field of Jupiter is likely to suck on a bullet even if it is misdirected. "Jupiter is so big, that will capture the bullet and then follow a curved path down on the planet," Flack said. And as it does, it will pick up some serious steam. According to Schultz, if the bullet shot straight to Jupiter, the planet's gravity will accelerate the ammunition to the amazing speed of nearly 60 kilometers per second at the time that crosses the threshold of the gas giant. watch your back shooting someone in the back is an act of cowardice. In space, "theoretically could shoot himself in the back," Schultz said. You can, for example, while in orbit around a planet. Since objects orbiting planets actually are in a constant state of free fall, you have to get the correct settings. It should be horizontally shoot just the right height for the bullet to turn around the planet and fall back to the starting point (you). And we should also consider how much they would pull him kicking back (and, consequently, the amount of your altitude will change) when the fire. "The goal has to be perfect," Schultz said. Such a scenario is not as absurd as it sounds. In fact, Schultz said scientists at a time were considering creating such a self-coup in space in order to investigate the effects of high-speed impacts. However, taking into account all the mathematics involved, Cuk suggests that it might be easier to commit suicide by space standing on a mountain on the moon. " 'Shoot himself in the back' works in principle, if a bullet is fired on the horizon from the top of a lunar mountain, 1600 meters per second or less," he said. He thinks it might work all the time you set your goal to account for bumps and irregularities in the shape of the moon, which would affect the height of the bullet as it travels. With so many frames of movies possible to consider, one question remains: Why is there so little space shoot 'em ups
