How fast can a bullet go in space?

Well, it would simply drift into the blackness, forever alone, while the galaxies around it sped further away. Those galaxies are travelling at around 200km/s (124 miles/sec) as the Universe expands, whereas a travelling bullet can reach speeds of only 1km/s (0.62 mile/sec).

Will a bullet lose speed in space?

"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.

Would a bullet travel faster on the moon?

So, neglecting air resistance, the bullet will go about 6 times farther on the Moon than on Earth.

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.

Can a bullet reach space from Earth?

No. There is not sufficient muzzle velocity for a bullet fired from any civilian or military firearm to reach space (escape velocity). This is an extremely dangerous practice and you are risking harm to other people. Do not ever do this!

Guns in Space

Can a gun be fired on the moon?

Despite the abundance of oxygen on Earth, however, most gun ammunition comes with its own oxidizer "built in", so to speak. The result is that a gun can fire even in the absence of oxygen, such as on the Moon.

Will a gun fire underwater?

If you're wondering how it's even possible to shoot a gun underwater, gunpowder contains oxygen — a key element in the firing process — the gun still goes off exactly as it would on land.

Can a Glock melt?

Well, if you're talking semi-auto fire, like the Glock was designed for, no human will ever get to the melting point.

Do Navy SEALs have waterproof guns?

But do they still have them? In the early 1970s, U.S. Navy SEALs and Underwater Demolition Teams got a special new weapon. The Mk. 1 Underwater Defense Gun helped combat swimmers defend themselves beneath the waves.

Can you shoot a shark underwater?

This led to the development of the APS underwater assault rifle, fielded in 1975 with an effective range of 100 feet underwater. The APS can also be used to shoot from air to water or vice versa. One of the stated uses is dealing with dangerous animals including, presumably, sharks.

Can we hear sound in space?

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would hear nothing.

Can you have a spark I space?

Lighter flints would probably not spark in space because the small metal particles need oxygen in the air to glow brightly however a fast grindstone grinding steel may produce rather dim sparks because the particles of metal ripped off by the grindstone are initially red hot but they cannot burn in space.

Does oxygen burn in space?

Fires can't start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways.

Would an M16 work in space?

In real life, however, a weapon like the M16 would be extremely difficult to operate in space. Using weapons in the extremes of space, including wild temperature swings and low gravity, would present challenges for both those who design and carry the weapons.

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.

What happens if you shoot an arrow on the Moon?

The moon isn't really zero-gravity, it is 1/6 Earth normal gravity. If there were no gravity on the Moon, the bullet and arrow would travel a tangential path along the surface and eventually leave the moon and go off into space.

Can you move in space by yourself?

If you are stationary in space with nothing around you to push off on, you cannot move yourself by pushing on yourself. But you can twist your body around its center of gravity - you just can't move your center of gravity. On Earth, we can walk forward because we push on the Earth and it pushes back on us.

Can a spark exist without oxygen?

A fire cannot burn without oxygen. You can show this for yourself, in fact: if you light a small candle and then put a clear glass upside-down over that candle (without touching the flame), you can watch the flame slowly extinguish as it uses up all of the oxygen that you have trapped around it with the glass.

How far can a spark travel?

A spark will spontaneously jump across a gap of 1 cm if there is a potential difference, of about 10,000 V across it. A larger gap needs a bigger potential difference so a spark will jump across a 3 cm gap if there is a potential difference of 30,000 V and so on.

How cold is space?

The Cosmic Background Explorer (COBE) satellite has refined temperature measurements taken way back in 1964. According to data from the Cosmic Background Explorer (COBE) satellite, the temperature of space is 2.725K (2.725 degrees above absolute zero).

Do you age faster in space?

Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

What happens if you fart in space?

On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you're an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.

What guns can fire underwater?

However, there are some Rare Guns that have been designed to work underwater. These include the Heckler and Koch P11 pistol and the APS Underwater Assault Rifle.

How far can a bullet travel underwater?

Typical bullets can travel just a few feet through the water before they're slowed to a stop. CAV-X bullets can reportedly travel 60 meters underwater, and can go through 2 centimeters of steel fired from 17 meters away, indicating that it could even be used to penetrate submarines.
