Can an explosion be heard in outer space?

Can an explosion be heard in outer space?

In space no one can hear you explode… Many astronomical objects such as novae, supernovae and black hole mergers are known to catastrophically ‘explode’. But as long as the explosion doesn’t require oxygen, then it will work in much the same way in space as on Earth.

Would explosions make sound in space?

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. Exploding bombs, crashing asteroids, supernovas, and burning planets would similarly be silent in space.

Can you hear anything in outer space?

Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).

Can you hear an explosion?

There is no “sound of the explosion” which could be transferred. Even in air at sea level, where explosions do generate sound, these sounds are not stored in macroscopic pieces of debris, moved with the debris and then released at another location.

Can guns fire 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.

Why can’t you hear an explosion in space?

To travel to us from outer space, the wave must be able to travel through regions of space which are essentially vacuum (nothing there). Sound cannot do this, as it requires a medium to propagate in, so we would not be able to hear the explosion.

Does space have a smell?

In a video shared by Eau de Space, NASA astronaut Tony Antonelli says space smells “strong and unique,” unlike anything he has ever smelled on Earth. According to Eau de Space, others have described the smell as “seared steak, raspberries, and rum,” smokey and bitter.

Why astronauts Cannot talk in space?

Sound waves travel by vibrations of molecules. Thus the speed of sound in air is slower as compared to solids and liquids. Now, when the two astronauts are floating close to each other in space, without the use of any special device, they cannot talk to each other because there is vacuum between them.

Can you breathe in space?

We’re able to breathe on earth because the atmosphere is a mixture of gases, with the thickest gases nearest the earth’s surface, giving us the oxygen we need to breathe. In space, there is very little breathable oxygen. This prevents the oxygen atoms from joining together to form oxygen molecules.

Why do you see an explosion before you hear it?

You can observe direct evidence of the speed of sound while watching a fireworks display. The flash of an explosion is seen well before its sound is heard, implying both that sound travels at a finite speed and that it is much slower than light. So a small instrument creates short-wavelength sounds.

Would a bullet travel forever in space?

Once shot, the bullet will keep going, quite literally, forever. (If the universe weren’t expanding, then the one or two atoms per cubic centimeter encountered by the bullet in the near-vacuum of space would bring it to a standstill after 10 million light-years.)

Can you shoot a bullet on the Moon?

The oxidizer is within the gun powder, so a gun will fire in the vacuum of the Moon. The bullet will travel significantly farther, because it will fall slower and there will be no air resistance. That can’t happen on the Moon.

Can you hear an explosion or any other sound in space?

But that isn’t true! Sound needs a medium to travel (such as air), but space generally doesn’t have it. Therefore, sound can’t really propagate in space. So you can’t hear an explosion or any other sound in space.

Why do you hear explosions in space in Star Trek?

Depending on the distance to the explosion, that could produce a considerable amount of sound inside the cabin (which does have air), but not damaging the ship in any significant way. It’s set in a different galaxy with different physics, much more fantastical, where science of our universe has no sway.

Can you hear the radio waves in space?

In the spacecraft, there is plenty of air, so they just talk normally. When they are spacewalking, they talk by means of radios in their helmets. The radio waves, again, have no problem in space, but they’re not sound. They’re radio, which has to be converted into sound by the astronauts’ headsets.

Are there any movies that have explosions in space?

So, out-of-universe, most space sci-fi movies have put sounds in space; the Enterprise whooshing by, sounds of phasers, blasters, and torpedos heard in shots taken from an in-space POV, even the “puff” of thrusters firing in Apollo 13 (1995), which was very technically accurate in most other respects.
