Do you want to have your mind blown? Because: actually THERE IS sound in space - really, really, REALLY quiet. Because - deep space is not really a perfect vacuum - there is about 1 atom of hydrogen per cubic centimetre. So, explosions such as a supernova DO create a sound wave - they are very quiet and very slow moving, but they definitely exist.

Exactly! Sound does travel through the vacuum of space, just not at a high enough frequency for human hearing to perceive. The frequency is very low; so low that it might be hard to describe it as sound at all. And sound travels very slowly in space, slower than a typical walking pace.

Sound, as it is conventionally understood, requires a medium to propagate which can reasonably be approximated as a continuum. That isn't true in the vast majority of space. Events like supernovas create shocks, not sound.

Oh well if you want to get really technical, geez. Haha just kidding yes you're right of course. Thanks for clarifying.
