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.
I thought a Sonic boom was when Sonic drops the mic

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
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.
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.
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!!
Ah, so this isn’t tinnitus, I can actually hear the sun!
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.
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…
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.
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.

I scrolled slow and mentally imagined it.

No love for Anton Petrov?
I guess I have a new one!
He’s a wonderful person :)
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!
i’ll definitely have to come back and check some of these out sometime.
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’s a fantastic science, with ever expanding horizons!
Pun appreciated.
That’s a stellar joke.
It’s out of this world funny.
Probably be a big roar. Like hurricane wind.
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.
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.
Noone rides the alot.
That’s great, thank you for that
My team. 🤘🏽
I like this alot
Nah, I’m different tho
Mama says.
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.
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. 🤔
That’s funteresting to think about.
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.
Or perhaps we’d use the reflected soundwaves to navigate with echolocation much like we use reflected light waves to see.
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!
