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

        Oh hey, thanks! Been hearing it for years, turns out I just never look left!

        I wish they’d give me my driver’s license back…

        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.

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

    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. 🤔

    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.

      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.

    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.

        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.

    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.

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