This is a sub for hard science after all, there's others better suited for creative writing ;)

> what would you think it would sound like if we could hear everything without consequences and death and not universal atmosphere, just like... our ears would be able to hear loud noises just fine and no destruction from sound... just imaginative... just a what if.

Ever been near a rocky seashore on a windy night?

Like that but louder than a jet engine 24/7 (mostly from the sun) with occasional gut-thumping cracks thrown in (from large celestial events) and maybe a couple discernible tones from millisecond pulsars depending on how loud of a sound your medium could carry before hitting vacuum at one extreme.

It would be pretty unpleasant
