#I can hear this image
I scrolled slow and mentally imagined it.
Just one small hitch: if there was an atmosphere in space dense enough to carry sound, the earth would burn up in minutes.
The planet could simply exist further back from the sun where the R^2 property renders the energy more diffuse.
Ah, so this isn’t tinnitus, I can actually hear the sun!
That or you’re standing next to a jackhammer.
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…
I’m not sure what kind of jack hammer you’ve used, but they sound nothing like Tinnitus.
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.
Mine is more of a mixture of static and a hum. Maybe what tingly would sound like.
I imagine it would be kind of like the hypnotoad sound
Obey the giant burning floating orb
All hail Almighty Ra!

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. 🤔
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.
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 (too much damage to cover up).
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, and will predict movementsand patterns, e.g. a baseball you’re trying to hit.
There’s also no colour in peripheral vision, although the brain does colour it in.Oh, didn’t know the one with no color in peripheral vision, that’s fun!
Or perhaps we’d use the reflected soundwaves to navigate with echolocation much like we use reflected light waves to see.
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.
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.
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.
Bees see UV too, it supposedly helps them navigating around flowers.
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.
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.
instrumental
Heh.
When I was little, I thought the sound of cicadas came from the sun.
They always did seem to get louder when a wave of heat would roll over the area.
It does. We can’t hear it, but it does.
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.
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.
That makes me wonder where the sun ends and it’s atmosphere begins! Stars are weird.
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.
Noone would live for longer than a few weeks after the sun went out.
Noone is one tough mf. I wish more of us could be like him.
Nah, I’m different tho
If it takes 13 years for sound how long would it take for us to reach the sun on a rocket
We can go faster than sound that’s what a sonic boom is.

This seems like bullshit to me. I don’t think the noise level of the sun is something we have solid data on
The sun apparently vibrates, but at frequencies too low to hear anyway. https://www.nasa.gov/solar-system/sounds-of-the-sun/
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/
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.
https://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.
That’s funteresting to think about.
