as a non astrophysicist, or just a non astronomer in general. it weirds me out every time i remember that there is literally a part of the universe that apparently exists, of which we will never be able to see, because the light from that part of the universe, quite literally hasn’t reached us yet.
The observable universe is inconceivably massive. But it just keeps going.
And to think it’s not an improbable concept for humanity to recreate the physics behind a big bang in a controlled setting, somewhere down the line from here, is certainly an interesting thought.

:0 how can you be inside a star and not know it? I thought they all had a surface like our Sun

See my response below to Captain Aggravated about how dilute those large stars are.
It’s an interesting question whether anybody would actually feel spaghettification 😁 I actually don’t know. You can use physics to calculate the proper time derivative of the tidal forces, but you need biology to define the start (and end…) of the process. My intuition says that it probably happens too fast, so once the tidal forces are strong enough to be perceptible, they grow strong enough to rip you apart before you realize (again, just a hunch).

Right? How can you not know it?
Hmm, am I in the star yet? I mean my body is now made of million degree hot plasma, but I’m still not sure…
