  It does (ok, one catch: if there’s an atmosphere), sound has physical nature. The trick is in asking whether music/art/languages exist after any sentient life is gone

    Can’t sound transfer through the casing even if it’s not vibrating air in the process?

      I think I’ve got your point: that’s not whar we call sound, but yes, the showel and casing will reverberate

      No, there is a well-known experiment: take something that produces sound, put in a glass, suck air out. Won’t hear a thing

    No, sound is a sensation. Sonic disturbances aren’t sound unless someone hears them. That’s why sonic frequencies outside the hearing range aren’t sound.

    You should read Berkeley’s Three Dialogues to properly understand the meme.
