Would that mean that stars like Mu Cephei would be even that much loader. That stars radius is 1000x the size of our sun and it shines 100000x brighter than our sun. Would there be any stars out there that we could hear is sound traveled though space or is everything too far no matter it’s size.

They meant if you were travelling precisely with the same velocity and vector as the wind you wouldn't hear it. Because then the wind isn't hitting anything since it is relatively at rest with your hearing instruments/ears.

I got you u/whatsagoinon1

A positive-pressure suit purged with your favoured blend of N2/O2 will suffice.

I wouldn't consider a solid core to be a solid surface, though.

This is a semantic distinction, though, at this point we would be arguing about what to call whatever is there, not a disagreement about what is actually there.

Though I'd prefer to distinguish between the core and the "surface" such as it is, I do think there's a reasonable argument to be made that "surface" should be identified as "whatever is solid." The problem with this terminology is that it doesn't really recognize any difference between gas giants and rocky planets, which I'd argue is a useful thing to do.

But, when it comes to what's actually there, I think we agree.

ie, a calibrated microphone.

Yes - it's not a trivial piece of engineering - and depends entirely on the altitude region of interest.

And you're best off integrating this onto a sonde/entry probe of some sort - a bare microphone in a tube will need a further other non-trivial items.

<power source, transmitter, etc.>

It depends on the altitude at which you conduct this courageous experiment.

It is a gas giant after all, so there are locales with pressures of 1bar, and altitudes with temperatures of 300K.

Sadly those regions do not overlap.

It is - for certain definitions of habitable.

If you don't mind living in a balloon-lofted city, and having a somewhat higher radiation does, it's quite the place.

No - they didn't "just go through" - they encountered gas that became increasingly denser as one sinks into Jupiter.

There probably is a solid core of rock, but before then you encounter multi-bar pressures, and densities exceeding that of common fluids here.

There is no “on” Jupiter. It’s a gas giant, light on surface.

The wind hits the ears that hear the wind.

PS: And by the way soundwaves are generated as long as any gas isn't traveling at uniform velocity and direction. Same as how waves on water happen without land.

Sounds like the jury is still out on a solid surface https://www.space.com/18388-what-is-jupiter-made-of.html

It depends where you are in the atmosphere. At some height, the pressure is going to be comparable to Earth’s atmosphere

So the metors that plowed into Jupiter years ago just went through? I thought, while small, that in the center there would be a solid something. Not big, because of all the weight and pressure, but something.

I feel like no one in this thread knows that Jupiter doesn't have a surface.

Those calculations assume a lossless atmosphere and that the only attenuation is geometric. Adding in attenuation leads to full thermalization surprisingly close to the photosphere.

Of course, if there were a medium to transport that sound, then it would effectively mean that the sun were just a much larger star, and that medium itself would be turbulent and noisy.

Thank God, I spend so much time hoping that insurance companies are doing OK.

Judging from this graph the temperature would be around 300K where the pressure is ~5 Atm. Pressures of ~5 Atm are found underwater on earth at depths of ~150 feet or so, which is routinely achieved by divers, including saturation divers who live at depths like that (or greater) for weeks at a time.

So definitely survivable, and even comfortable. Neglecting the chemical environment and the wind, of course. But you can be protected from a harsh chemical environment with some pretty simple coverings and depending on the variability of the wind you might be able to ride along with it in a way that's not too uncomfortable.

A few well-aimed bullets should fix it

Don’t tell me what I can’t do.

Oh, thanks. I thought you ment Kalvin, but the rest made no sense. Thank you.

Hmm... do we have any idea what the pressure is at the altitude band averaging 20-30C? Or, heck, even 5-40C? Still tolerable with the right clothes.
