Why can we hear sound on earth but not in space?

Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

Do you need an atmosphere to hear sound?

For this to happen, sound needs a medium like air, which contains molecules that can move and conduct the wave onwards. When sound hits a physical structure, like an eardrum, the structure vibrates.

Why we Cannot hear sound produced from an explosion in outer 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.

Can you hear waves in 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).

How can there be sound in space?

Space is a vacuum. With no molecules in the vacuum of space there is no medium for the sound waves to travel through. So there is no sound. And that is the reason nobody can hear you shout in space.

Can you hear in space if you scream?

That infamous tag line from 1979’s Alien, “In space no one can hear you scream.” No one can hear you because the audible sound waves from that scream can’t pass through space. And once sound waves drop below 20hz, they become infrasounds and are not audible to humans.

How quiet is space?

Space isn’t completely quiet — in fact, it’s rather loud. That being said, if you scream in space, the sound will still technically travel; just at too low a frequency for our ears to be heard. In essence, there’s no medium for the vibrations to travel through.

Why is there no sound in space?

They say that there is no sound in space and that it is because there is no air in space. For instance if someone were talking to you, you couldn’t hear what they were saying. Answer by Lynn: You’re right that there are gases in space, and it’s true that these gasses can propagate sound waves just like Earth’s air allows sound to travel.

Can sound travel through the vacuum of space?

Of course, if someone were in space without any protection against the vacuum, hearing any sound waves would be the least of their problems. Light waves (that aren’t radio waves) are different. They do not require the existence of a medium in order to propagate. So light can travel through the vacuum of space unimpeded.

Why does the Earth’s spokes make noise in space?

When observed using a radio astronomy receiver, the process of the spokes’ rotation gave off radio emissions, which astronomers processed to create ghostly “sounds”, although no such sound was heard in space.

Can space make music?

Without air there is no sound. But if that’s true, what was space physicist Don Gurnett talking about when he stated at a NASA press conference in Sept. 2013 that he had heard “the sounds of interstellar space?” It turns out that space can make music … if you know how to listen.
