In space no one can hear you scream

Sound needs molecules in order to set up a vibration.
Air and water are great, metals too … but space.
Space is near empty as far as molecules of anything goes.
So there is no way for a sound wave to propogate.

Now we are talking about sound waves we can hear.
There are “electromagnetic waves” in space and they can be translated to something we can hear.

As for sound waves … no molecules … no sound.

Just to remind you where it all came from …
