No, there is no sound in space because there is no air.Without air sound will not travel anywhere. Sound is created by a wave moving. For a wave to move, it needs a medium. Sound travels in air or water. There is no air or water in the vacuum of space.

Believe it or not...this is actually false.

An amazingly sensitive microphone, in a sense, was used to discover the constant B-flat coming from a black hole. (This found on NASA's website. Based on research from NASA's Chandra X-ray Observatory."

This comes from the Space.com website...

"Sound can travel through space, because space is not the total vacuum it's often made out to be. Atoms of gas give the universe a ubiquitous atmosphere of sorts, albeit a very thin one. Sound, unlike light, travels by compressing a medium. On Earth, the atmosphere works well as a sound-carrying medium, as does water. The planet itself is very adept at transmitting an earthquake's seismic waves, a form of sound. Space, though not as efficient, can also serve as a medium. If a brave and clever astronaut could safely remove her helmet and shout into the cosmos, her voice would carry."

Also do keep in mind that actually their are tons of particles in space. Just not near as many parts per million as here on Earth. As a matter of fact NASA has even released such research on this to attempt to solve a problem with near light speed travel. Hydrogen atoms would bombard the front of the craft at high rates of speed. Essentially such a collision of particles would break up the vehicle in a short amount of time. This alone proves space isn't a pure void. Besides...their is nothing to force all the molecules in the universe to stay attached to everything. Therefore it only seems logical to assume some do escape into the "void" we know as space.

Why are we unable to hear sound in outer space?

There is no sound in outer space because space is a vacuum. Sound needs matter to travel through and vibrate in order for us to hear it. Air vibrates in our ears to make us hear sound. Since space has no air we wouldn't be able to hear anything.


Can sound waves be used to propel a ship through space?

Sound waves cannot be used to propel a ship through space because sound requires a medium, such as air or water, to travel through. In the vacuum of space, where there is no air or other medium, sound waves cannot propagate. Propulsion in space relies on different principles, such as Newton’s third law of motion, where thrust is generated through the expulsion of mass, typically utilizing rocket engines. Therefore, sound waves are not a viable means of propulsion in the vacuum of space.


Do sound waves travel through space?

Not unless there's some material matter in the space.


Is space silent?

Quite easy to understand, really. Sound needs a material substance to travel through from place to place. The one we're most familiar with is air, but sound travels very easily through steel, glass, wood, water, etc. There's no material substance in space, so sound just can't travel from place to place. And that's all there is to the whole story.


Can you here in outer space?

No. Sound is distributed by the collision of molecules/atoms transferring energy to each other. Space or vacuum, by definition is completely empty, with no molecules to facilitate this transfer, and hence sound cannot propogate through space. The movie 'Alien' famously had the line 'In space, no one can hear you scream' or something along those linesThis answer is perfectly correct, but to those who do not (the very few) understand this text, this answer is, literally: In space or vaccum, sound does not travel because sound is transferred through cells, molecules/atoms, as you say, and there is nothing there, no cells or atoms or molecules, therefore the sound cannot be passed on. -.- that was absolutely pointless, but I'm currently, very, very bored.Sound does not travel through a vacuum.Sound requires a medium to travel thru. Since there is nothing in a vacuum, there are no particles to transmit the sound.
