How would one exit a black hole?

Which technology? Become a bigger AH than the black hole?

With super massize black holes, you could pass the event horizon and not even know it. To you, everything would remain relatively (no pun intended) comfortable. You could live for a couple days, falling towards the singularity before the gravitational gradient becomes enough to rip you apart, thus ending your life.

Now I have a doubt. Could you have a stable orbit around the singularity but inside the event horizon?
Maybe you could live a comfy life there.

That’s actually not that hard, if we’re talking about a rotating black hole that’s sufficiently large (like the supermassive ones are).

You evaporate over billions of years via Hawking radiation.

That assumes black holes aren’t the Big Bang white hole events of new pocket universes of the fizzy foam multiverse.
You could be part of a whole new universe! You wouldn’t know it, but how fun!

What if I have somewhere to be before then?

As if being shredded atoms wasn’t harsh enough, you don’t even get keep your neutrons and electrons in this process. I guess it still counts as “exiting” the black hole, but just barely.

Well your information is preserved in the universe and that’s all any of us can really lay claim to anyway.

Try more like trillions of trillions of trillions… repeat a few more times.

Luckily time flies fast inside.

by entering a black hole nested in that black hole

You wait for it to reach a critical mass and explode. Might take a little while.

depends how close you are, and not getting spaghettified.

You’re maybe thinking of white dwarfs. Black holes don’t do that.
victorz@lemmy.world 8 months ago
Do they do that? Is that what the Big Bang was?

More or less. In my layman’s understanding: Black holes ‘evaporate’ slowly through Hawking radiation, losing mass as a function of their surface area (simplistically, particle/anti-particle pairs ‘pop out of nothing’ near the event horizon, one gets swallowed up the other escapes, this means a net loss of energy, which has to ‘paid’ by the black hole losing mass, think E=mc^2^).
Since a black hole behaves (geometrically) like any other sphere, the proportion of its area to its volume will grow as the black hole loses mass (i.e. it will have more and more relative area the smaller it gets), this process speeds up over time thus ending in what I guess you could call an explosion (more a whimper than a bang, to borrow a phrase).
Part 2 of your question: We don’t know.
