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.
the sheer scale of the universe makes me want to get into astronomy.
Do it! It’s a fantastic science, with ever expanding horizons! That being said, if working in the field is a bit too much, amateur astronomy is a fabulous and friendly hobby - if a bit expensive
it does sound like a fascinating field, but im not sure there’s much in it for me outside of a hobby. I guess i need to look into what the field actually does lol.

Pun appreciated.
That’s a stellar joke.
It’s out of this world funny.

He’s a wonderful person :)
I guess I have a new one!
Astrum, history of the universe and PBS spacetimes content is soooo good they absolutely get money from me regularly and I hope they stick around for decades to come!
Yes. HOTU is the best channel I swear. They are so professional and so polished.
That last bit is a little poetic to say the least.
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.
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.

Probably be a big roar. Like hurricane wind.
I imagine it would be kind of like the hypnotoad sound
Obey the giant burning floating orb
All hail Almighty Ra!

Nah my mind went to Stargate
I’ll admit I’ve never watched Stargate, but I thought it was scifi? I didn’t realise it engaged with Egyptian mythology.
It heavily features a race of creatures that have posed as gods throughout most of human history, so it touches on almost all the mythologies. Egyptian mythology features very heavily, with Ra being the first of this alien race that the series engages with.
Oh neat. I should get around to watching it.
Dang, we’d have to wear ear protection all day!
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/
The sun apparently vibrates, but at frequencies too low to hear anyway. https://www.nasa.gov/solar-system/sounds-of-the-sun/
That’s funteresting to think about.
Just one small hitch: if there was an atmosphere in space dense enough to carry sound, the earth would burn up in minutes.
And apparently it would be quite loud during the burning!
Well yeah, I wouldn’t expect people and other animals to be quiet while the entire planet is burning up.
JACKHAMMERS I TELL YA!!
The planet could simply exist further back from the sun where the R^2 property renders the energy more diffuse.
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.
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.
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.
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.
If it takes 13 years for sound how long would it take for us to reach the sun on a rocket
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 need 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.
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
Found the KSP player
Easy to spot, huh
You sound like a modern shaman
I’ll take that as a compliment :D
As the other person called out, it’s the KSP experience coming in clutch
Wow I didn’t think it’d be that complicated haha, I imagined we’d just swirl towards it like going down thr toilet
Sometimes I wish the earth did that
We can go faster than sound that’s what a sonic boom is.
I thought a Sonic boom was when Sonic drops the mic

Evolution would say: nope. And the surviving class would be deaf. No one is able to accept a permanent jackhammer.
Or evolve the ability to echolocate with the reflections of the background noise. Like our eyes does with light.
Evolution might just block out certain frequencies. No need to go completely deaf.
Like the frequency dying plants make? Makes sense. Looks like evolution could already did this in the past.
Thanks for making me aware 🙇
Wait you mean you guys can’t hear that?
I’m sorry what the fuck now
alright that’s it, I’m never eating plant based food again.
What… What’s let to eat then?
Fungi.
meat, exclusively
I can hear this image
I scrolled slow and mentally imagined it.
