Sound travels at the speed of light through space
there is no sound in the vacuum of space because there are too few molecules to propagate a wave.

Here let me clear this up. Sound is obviously waves that are in the form of decibles...
Radio waves and all the other em waves are the transmission of sound waves. If i'm standing on the moon and I cought through the transmitter your gonna hear it on earth. I made a sound on the moon you heard it on the earth.
Therefore sound is everything!

Em waves are proof that sound can exist in many forms! Down at the quantum level no matter what we are talking about everything is produced by vibrations. Those vibrations are caused by sound!
It's unbeatable!
Sound waves can travel only through matter. Since there's almost no matter in interstellar space, sound can't travel through it. The distance between particles is so great that they would never collide with each other. Even if you could get a front seat for the explosion of the Death Star, you wouldn't hear anything at all. Technically, you could argue that there are ways a human could hear in space. Let's address a few scenarios:
Radio waves can travel through space. So, if you're wearing a space suit that contains a radio unit and one of your buddies sends you a radio message that there's pizza in the space station, you'd be able to hear it. That's because radio waves aren't mechanical -- they're electromagnetic. Electromagnetic waves can transmit energy through a vacuum. Once your radio receives the signal, it can convert the signal into sound, which will travel through the air in your space suit without a problem.
Let's say that you're drifting through space while wearing a space suit and you accidentally bump your helmet into the Hubble Space Telescope. The collision would make a sound that you could hear, even though you're in space. That's because the sound waves would have a physical medium to move through: Your helmet and the air inside your space suit. You'd still be surrounded by a vacuum, so an independent observer wouldn't be able to hear anything, no matter how many times you rammed your head against a satellite.
Imagine that you're an astronaut on a space shuttle mission. You've decided to step out into space but forgot to put on your space suit. You press your face against the space shuttle. You wouldn't have any air in your ears, so you couldn't hear in the traditional sense. However, you might be able to make out a few sounds through bone conduction before the perils of space caused you to expire.
In bone conduction, sound waves travel through the bones of the jaw and skull to the inner ear, bypassing the eardrum. There's no need for air, so you could hear your fellow astronauts partying inside the shuttle for about 15 seconds. After that, you'd likely be unconscious and well on your way to asphyxiation. So despite the wisdom of Hollywood filmmakers, it's impossible to hear noises in space. We suggest the next time you watch a science fiction film, you plug up your ears whenever anything happens within the vacuum of space. It'll make the film seem more realistic and probably work as a great conversational topic with your friends once the movie's over.

And I said they do as em waves!
