  • leadore@lemmy.world ⁨8⁩ ⁨months⁩ ago

    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. 🤔

    source
  • xantoxis@lemmy.world ⁨8⁩ ⁨months⁩ ago

    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.

    source
    • stephen01king@lemmy.zip ⁨8⁩ ⁨months⁩ ago

      By your logic, light isn’t a useful sense to possess since it’s everywhere all the time thanks to sunlight and moonlight, is that correct?

      Actually, since ultraviolet radiation and light are both electromagnetic waves, they should be treated the same, shouldn’t they? It’s as if there could be a different reason why we can detect one but not the other.

      source
      • chatokun@lemmy.dbzer0.com ⁨8⁩ ⁨months⁩ ago

        Yes, and some animals (mostly birds iirc) do see UV. Boring brown/black birds aren’t so boring in UV. I don’t know the evolutionary pressure necessary for UV, but it could have developed. Red, for instance, is believed to have been useful for us to pick out berries. Wolves, being carnivorous, wouldn’t necessarily need it, so see in yellow blue… or so I read as a theory a while ago.

      I assume that this thought experiment posits a space filled with the same average density of particles found at ground level on Earth. Obviously such a thing is nonsensical, but it serves to illuminate one aspect of the raw power of the Sun that we ignore, because we’re insulated from it by 93 million miles of vacuum.

      source
    • SapphironZA@sh.itjust.works ⁨8⁩ ⁨months⁩ ago

      If the sound is more of a loud hiss, you might find that echolocation can work very well. Much like our eyes collect available light bouncing off surfaces, similar techniques can be used with sound.

      source
  • Etterra@lemmy.world ⁨8⁩ ⁨months⁩ ago

    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.

    source
    • CitizenKong@lemmy.world ⁨8⁩ ⁨months⁩ ago

      I mean we hear the sound of our blood rushing through the veins of our ear 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.

      source
      • filcuk@lemmy.zip ⁨7⁩ ⁨months⁩ ago

        The way senses are processed is almost unbelievable.

        When your eyesight is partially damaged (by a laser, for example), your brain will fill in the spots, so you won’t even realise there’s a problem until it’s too late.
        As the above stated, there’s a blind spot (although I don’t think it’s smack in the middle) - there are tests online you can try to ‘see’ it.
        Your sight also automatically enhances objects it thinks are important, e.g. a baseball you’re trying to hit.
        There’s also no colour in peripheral vision, although the brain does colour it in.

      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.

      source
      • prime_number_314159@lemmy.world ⁨8⁩ ⁨months⁩ ago

        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.

    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.

      Okay just to be clear. The sun not only went out. The sun will explode and we too.

      source
      • chatokun@lemmy.dbzer0.com ⁨8⁩ ⁨months⁩ ago

        A lot of the suppositions are done with impossible to happen stuff, like the sun literally disappearing, or collapsing into a blackhole with no added mass (a sun mass blackhole would be stable, but I don’t know how one could be created).

        If it disappeared, then we’d still feel even gravity for those 8 mins, as the effect of gravity propagated at the speed of light. If it somehow magically became a black hole, we’d still orbit it the same even after 8 mins, but losing all the head would eventually kill us.

        The expected explosion wouldn’t be what makes the earth uninhabitable either. The sun increases in luminosity by ~1% every 100 million years, and it’s estimated that between 700 million and 1.5 billion years the surface of the planet will be too hot for liquid water. An astronomer also says photosynthesis would be impossible in 500-600 million years.

      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 www.reddit.com/r/askscience/comments/…/cqpsap8/

      Interesting question.

      You’d have to cancel out the sideway movement of the earth, and it’s going roughly 85000km an hour.

      Once you cancel that out, you’ll simply fall down to the sun. But you’d never a very powerful rocket. It’s way easier to get to mars, as comparison.

      It’s more realistic to do gravity assists from venus and other bodies, and in that case it’d take years. Just a rough guesstimate would be 10 years I guess? But maybe you’d have to even sling past jupiter or something to really slow down, so then it might be decades.

      source
      • itslilith@lemmy.blahaj.zone ⁨8⁩ ⁨months⁩ ago

        If the planets line up correctly, you can do it in way less, like 4 or 5 months. I’d need to get some orbital calculations out for the whole thing

        But simplest case, you lower your perihel to Venus orbit, that’ll take you less than half a year. With a perfect gravity assist you can then head straight for the sun at more than orbital speed, accelerating as you go. Free fall time is a fraction of orbit time, and you’re going in with a high initial velocity, so a month or two more, max. That’s 6-9 months total, but it’ll be faster with more Δv

    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.

    so, someone did the math on that?

    no vacuum, that means atmosphere. so lets say 1 atmospheric pressure the whole way.

    which would be sad, because rain, clouds, ozone layer and countless other atmospheric phenomen would be impossible. so no life on the planet anyway.

    en.wikipedia.org/wiki/Acoustic_attenuation

    how loud is the sun? does anybody know? what is the acoustic pressure on a certain orbit near the sun, iof there is atmosphere?

    so, the acoustic presssure needs to reach earth. it needs to travel 13 years.

    overcoming this much atmosphere between sun and earth eats energy, since there is a resistance. because there is an atmosphere, see? thats why sound gets softer and softer, the more away you are from the source.

    so I guess the whole idea is bullshit.

    but i am just a construction worker, maybe someone else will do the math.

    i doubt any light rays would make it here. it would be pitch black dark.

    the light would be scattered by the atmosphere.

    the vaccum does not block sound. it just doesnt transmit it. there is nothing what can block.

    same as vacuum does not suck. never. the key is pressure differential, the higher pressure dictates what will happen, not the lower pressure.
