Would a bullet in space travel forever?

Once shot, the bullet will keep going, quite literally, forever. "The bullet will never stop, because the universe is expanding faster than the bullet can catch up with any serious amount of mass" to slow it down, said Matija Cuk, an astronomer with joint appointments at Harvard University and the SETI Institute.

How fast would a bullet travel if fired in space?

If you were to fire a gun in space, what would happen to the bullet? At 9000km altitude, escape velocity is about 7.1km/s. A rifle's muzzle velocity is around 1km/s, so a bullet fired from a stationary position would either be caught in an orbit or eventually fall to Earth, depending on the direction of fire.

Would a bullet float in space?

Assuming you are floating freely in space the gun will work just as it does on Earth. However, the bullet will continue moving for many thousands of years, eventually coming to a stop due to the friction from the diffuse material found in 'empty' space (or when it encounters another object).

Can guns be fired in space?

Fires can't burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.

Would guns recoil in space?

What this means is that if you were floating in space and fired a gun, the recoil of the gun — that force that pushes against your shoulder on Earth, but which your feet and gravity help to stop — would push you backward, though you wouldn't really feel it.

What Happens If You Fire a Gun in Space?

Could a bullet escape the Moon?

The moon's escape velocity is about 2.38 km/s, but a bullet typically travels at only about 1 km/s. So take cover - even in this case, what goes up must come down!

Can a bullet escape gravity?

Even a bullet, fired straight up at the maximum speed a gunpowder blast can accelerate it to, will never leave the lowest layer of Earth's atmosphere. A combination of gravity and air resistance will slow it down until it reaches a maximum height, whereupon it will fall back down to Earth's surface.

Do astronauts carry guns?

Guns were never carried aboard U.S. spacecraft. Instead, a sharp machete served as the most serious armament for a jungle landing. Besides, with a worldwide U.S. network of bases and existing air-sea rescue forces, odds were that any downed astronauts would be found and rescued pretty quickly.

What happens if a space suit is punctured?

An astronaut can die many ways, but decompression is one of the more gruesome. A punctured space suit means a race to sanctuary, before the envelope of pure oxygen surrounding the body bleeds away and hypoxia causes the person to black out.

Why do astronauts need a knife?

The Astro knife was strong enough to open the capsule hatch with force if needed (try that with a folding knife) and ready for survival situations. Cooper knew that astronauts could find themselves in inhospitable areas like desert, jungle and even oceans after a bad landing.

How do ISS get water?

Water recycling on the ISS is controlled by the Environmental Control and Life Support System (ECLSS). This system of machines provides both clean air and water to the ISS crew and laboratory animals. The part of the ECLSS that controls water reclamation is the Water Recovery System (WRS).

How far can a bullet go straight up?

A bullet fired straight up, with no wind, might reach a height of 10,000 feet (about three kilometers), but will come back down at only around 150 miles per hour: just 10% of the speed and with only 1% of the energy as the originally fired bullet.

Can a bullet escape the Earth's atmosphere?

Even a bullet, fired straight up at the maximum speed a gunpowder blast can accelerate it to, will never leave the lowest layer of Earth's atmosphere. A combination of gravity and air resistance will slow it down until it reaches a maximum height, whereupon it will fall back down to Earth's surface.

How far will a 22 bullet travel before dropping?

22 caliber. It can travel around 1.5 miles at a 12,000 foot altitude," Paskiewicz said. Many factors go into where a bullet travels like wind, obstacles, weight of bullet and trajectory.

Can you throw a rock from the moon to Earth?

Even if all other conditions were identical to those on Earth, this alone would be enough to send it farther, but the lack of atmosphere and reduced gravity would contribute even more distance. To get the maximum horizontal distance, you would have to throw the rock at a 45-degree angle.

Can you hit a golf ball from the moon to Earth?

There is no air resistance on the moon to slow the ball's travel. The faster one hits a golf ball, the farther it moves as no fluid resists it. As for making a ball leaving the moon altogether, well, a human truly couldn't. The moon's gravity is weaker than Earth's, but still quite strong.

Can you hit a golf ball into orbit on the moon?

No, you cannot hit a golf ball into orbit on the moon.

How many miles does it take to escape Earth's gravity?

At 11km/s you can successfully break orbit and escape the gravitational pull of the Earth. At 10km/s the Earth will eventually slow down your ascent till you begin falling back towards the ground. These values are at ground level.

Why do you have to go so fast to escape Earth gravity?

Escape velocity is a mathematical definition. What initial speed do you need to reach infinite distance to the planet. It takes infinite time to get there, but the escape velocity has the necessary kinetic energy for infinity. To reach a low or higher orbit, less energy and velocity is needed.

Can you dodge a bullet?

Bullet dodging, Scientific American reports, is one such make-believe ability invented by Hollywood. Regardless of your speed and finesse, no human can dodge a bullet at close range. The bullet is simply traveling too fast. Even the slowest handguns shoot a bullet at 760 miles per hour, SciAm explains.

How fast is the fastest bullet in mph?

The fastest bullets travel more than 2,600 feet per second. That's equivalent to over 1,800 miles per hour. To put that in perspective, it's amazing to realize that bullets travel over twice the speed of sound!

Does a bullet break the sound barrier?

In fact, bullets can move fast enough to break the sound barrier. Contrary to what the name might suggest, the sound barrier is not an actual wall or barrier. Rather, it is the hypothetical limit to the speed an object can travel before it exceeds the speed of sound.

Can astronauts drink alcohol in space?

Alcoholic drinks are generally disallowed in spaceflight, but space agencies have previously allowed its consumption. NASA has been stricter about alcohol consumption than the Roscosmos, both according to regulations and in practice. Astronauts and cosmonauts are restricted from being intoxicated at launch.

Can you poop in space?

To poop, astronauts used thigh straps to sit on the small toilet and to keep a tight seal between their bottoms and the toilet seat. It didn't work very well and was hard to keep clean. So in 2018, NASA spent $23 million on a new and improved toilet for astronauts on the International Space Station.
