imagine living on a cold dead earth for thirteen years

you'd be dead in a week

I guess the sun being loud shouldn't really be all that strange; if I recall correctly the sun has explosions happening on it everywhere all the time, the strange part though is the whole sound lasting for thirteen years part.

That’s funteresting to think about.

First time I saw the North Lights in person I also expected something other than complete silence. I don't know what, but they're so surreal and massive I thought you'd hear something.

That last bit is a little poetic to say the least.

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.

Probably be a big roar. Like hurricane wind.
