    Just one small hitch: if there was an atmosphere in space dense enough to carry sound, the earth would burn up in minutes.

        Nah. It starts out like THUD! THUD! and then slowly after a couple minutes of warming up, that goes all muffled and it becomes that familiar high-pitched ringing noise.

    On the plus side, if we evolved on Planet Sunblaster then our hearing would have evolved to either dial down the volume or filter it out completely.

      I mean we hear the sound of our blood rushing through the veins of our ears at all times, but our brain filters it out. That the “sound of the ocean” you hear when listening into a conch, it just amplifies the bloodwaves. Other fun stuff our brain does: Our eyes are actually perceiving the world upside down and with a blind spot right in the middle.

      Or perhaps we’d use the reflected soundwaves to navigate with echolocation much like we use reflected light waves to see.

    If the sun were to go out it would take 8 minutes for the light to stop but 13 years for the sound to stop.

    Kind of like when you kill an enderman. 🤔

    Evolution would say: nope. And the surviving class would be deaf. No one is able to accept a permanent jackhammer.

    You wouldn’t, of course. Hearing, the way we hear, in such an environment would be useless. We wouldn’t have evolved that. This is like saying “ultraviolet radiation from the sun would be everywhere, all the time, can you imagine?” It is everywhere all the time, but as such it isn’t a useful sense to possess, so we don’t.

    This also makes some very weird assumptions about what the sound would be like. If space were a medium sound could travel through then it would–like all mediums capable of carrying a sound wave–alter the wave in many ways. Intensity, frequency, etc. But since we don’t know what kind of medium that would be, and since the comment doesn’t posit any particular medium, we don’t know what the sound would sound like or even how loud it would be.

    imagine … hearing the jackhammer scream of our star

    Sounds are a form of energy. If we were bombarded by sound waves for the entire existence of the planet, I assume life would have adapted to harness this abundant power source and made it instrumental to how we survive and thrive.

      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.

        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.

          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.

    This seems like bullshit to me. I don’t think the noise level of the sun is something we have solid data on

      I traced down this loud sun theory, and it comes from a post from reddit of a guy who did the maths and obtained a volume level of 100dBA, although with one bold assumption, which is that the sound of the sun would propagate just as well as its light, which would absolutely not be true if there was an atmosphere between the sun and the earth. This reddit post has then been cited in a few articles. Sauce for anyone interested https://www.reddit.com/r/askscience/comments/33xuxu/comment/cqpsap8/

    A bullet fired from a gun goes more or less at Mach 1, correct?
    It’s thirteen years to the sun at the speed of a bullet?

    Spacecraft towards Mercury, or the Parker Solar Probe go much faster than that, take a few years to make it there, but they are doing so picking up speed in flybys of first Earth, then Venus, then Mercury, in several, ever tighter orbits.

    It’s both fun and illuminating to try and visualize these things in new ways. In this case, from the viewpoint of a bullet.
