Can you have compression waves that propagate through dense areas of stuff but the “stuff” isn’t very structured (structured like rocks, gas, etc)... like particles or photons?
Post Body
I was thinking about how sound doesn’t propagate through vacuum because it needs a substance. What if you were really close to a star where photons are dense or something like that? Would you hear sound? Maybe like the sound of the sun?
I guess I kinda struggle to understand the difference between something like that and what we’d call an atmosphere, albeit atmospheres tend to be a little less fleeting.
