supernova explosion

because we recorded the radio waves, and then played it back as if it was a radio channel.

Technically there is no audiable sound in space because space is a vaccum and sound cannot travel through a vaccum SO....
why did we hear the radiation of the left over from the Big Bang?

As stated before, for sound to travel it needs a medium and space DOESN'T have any gas, plasma, or other particles apart from the obvious planets and stars and things of that sort. Space is SPACE as in, there is nothing in it. It's just vast emptiness. Sound waves travel by bumbing into molecules which i turn bump into other molecules and so forth. The molecules are the medium. There are no particles in space. Therefore, sound cannot travel and you would not hear a supernova explosion in space.

Well you need to understand what you call "sound in space". You can register impacts of helium atoms from solar wind... And the impacts technically is a sound. You wouldn't hear it with your ear but with special apparatus. Why not?
In case of this vid. Considering proximity to the the exploding star you would be hit by shockwave from explosion and that would be gas. Lots of molecules. So sound is an option here also. Assuming you survive teh event:)

shot balla3310, you obviously don't know anything if you think there is sound in space. sound is a longitudinal wave which needs a medium such as air, water etc to travel through. as space is exactly that, empty space. longitudinal waves like sound cannot pass travel through it. you are getting confused with transverse waves such as light which do not need a medium to travel through. next time learn basic physics before commenting. retard.

Well obviously this video is edited Im not stupid, and yes there is sound in space but there is no air so no way for it to travel, if you were in space near an explosion you would not hear it.

yes that is true but still only if you stuck a speaker to an asteroid and listened on the other side it would work or a stream of water going from your ear to a speaker but in just plain space there are no particles just a void no forces 'cept gravity from planets and stars at times but no way for sound to travel vibrations dont work if there isnt anythin to vibrate duh.

YOUR AN IDIOT. Are you saying there are no particles in space? There's no dust? No rock? Your wrong gtfo. It can vibrate of anything.

yes but vibration needs a state of matter to travel through it needs particles to vibrate, air is a gas which vibrates strongly allowing sound to pass hhowever in space there is no gas,solid,liquid,or plasma.
