[–] lath@lemmy.world 28 points 2 years ago (1 child) It does. We can't hear it, but it does. permalink fedilink source hideshow 2 child comments replies: [–] degen@midwest.social 19 points 2 years ago (1 child) Well, I think technically it doesn't. There's no medium to propagate pressure waves, so at no point would the mechanics of sound actually exist, I would think. permalink fedilink source parent hideshow 2 child comments replies: [–] prime_number_314159@lemmy.world 20 points 2 years ago (1 child) The sun itself is a medium that can propogate sound waves. Someone standing on the Moon could equally well make the case that there is no medium to propagate pressure waves from the Earth, so the Earth must not make a sound. permalink fedilink source parent hideshow 2 child comments replies: [–] degen@midwest.social 5 points 2 years ago* (last edited 2 years ago) (1 child) Aye, true. Though I would consider that case different (slightly, but not fundamentally wrt waves existing) from the sun because on earth there are atmospheric sound waves that just don't reach out to the moon. But I hadn't thought of the possibility of waves going into the sun, so there would be existing waves there too. More akin to making a sound on the moon by vibrating the moon itself I suppose. Edit: and really, I'm talking out of my ass lol. There could very well be gases or some such to vibrate around the sun, even coming out of the sun and carrying vibrations, but I don't know enough. permalink fedilink source parent hideshow 2 child comments replies: [–] Bumblefumble@lemm.ee 6 points 2 years ago (1 child) The sun has an atmosphere so there are soundwaves coming out of it. It's actually all one big atmosphere getting thinner and thinner as you go out just like ours. permalink fedilink source parent hideshow 2 child comments replies: [–] degen@midwest.social 3 points 2 years ago (1 child) That makes me wonder where the sun ends and it's atmosphere begins! Stars are weird. permalink fedilink source parent hideshow 2 child comments replies: [–] Bumblefumble@lemm.ee 6 points 2 years ago Technically there is no boundary, it's atmosphere all the way in. But what we might call the "surface" is the photosphere. That is where the density becomes "low" (read not insanely high) enough that light can escape in a free path. permalink fedilink source parent
