How would one exit a black hole?
Feeling like taking a vacation.
You go into a white hole, duh
The only direction is forward. Better hope it leads somewhere.
You just pop out the white hole on the other end.
One wouldn't
Through a white hole.
(not kidding)
Space time gets so curved that literally every direction around you is the center of the black hole.
You look forward? Black hole center.
Behind you? Center
Up down? You guessed it
From your perspective, the center literally is the only direction you can go, deeper.
Vacation is seeming further and further away.
Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.
When you're ready, you should see a bookshelf. Start messing with the books to send a message to your daughter and maybe she will help you.

don't fight against gravity by trying to fly directly towards the universe. Instead, fly parallel to the universe until you are out of the black hole's pull, then angle back towards the universe.
No no no. You need to take the u-turn at the other end of the universe.
Through the gift shop.
You evaporate over billions of years via Hawking radiation.
Try more like trillions of trillions of trillions... repeat a few more times.
As if being shredded to 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.
Literally, impossible. To exit the event horizon of a black hole, you'd have to travel faster than the speed of light. We know for a fact that anything with mass cannot travel at the speed of light. (And anything without mass MUST travel at the speed of light) Once you cross the event horizon, you've been entirely and irreversibly separated from the rest of the universe.
And anything without mass MUST travel at the speed of light
You're not the boss of me! I do what i want!
It's not even about needing to exceed the speed of light. Once you cross the event horizon, spacetime around you is so warped that "out" doesn't exist anymore. Point your ship in any direction and fire up your FTL engine; it doesn't matter. No matter which way you try and fly your ship, you'll be getting closer to the center. Once you cross the event horizon, there is literally no way out.
I love how mind bending it is imagining what lies inside a black hole. Everything we know about physics may essentially go right out the window beyond the event horizon.
Does this also mean that black holes are totally indestructible?
Well, there's the hypothesis of a "naked singularity" whereas if enough charge or spin could be added to a black hole, the event horizon, aka, the black part of a black hole, could just vanish. This would expose the singularity at its center but its just a hypothesis. Or better yet, a thought experiment at best. This wouldn't eliminate its mass though.
Basically.
They slowly decay as hawking radiation, but there’s nothing you can do to speed up the process.
Just use the same technology that allowed you to enter a black hole without dying.
With super massive 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.
Which technology? Become a bigger AH than the black hole?
I mean... kind of.
That's actually not that hard, if we're talking about a rotating black hole that's sufficiently large (like the supermassive ones are).
go to the other end
Exactly, when you're going through hell, keep going. Maybe you'll find a white hole in the other end with a new universe to explore.
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.
Do they do that? Is that what the Big Bang was?
They don't. They do evaporate though.
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=mc2).
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.
With the assumption that we are alright in there, wait until it evaporates naturally. I hope you brought a lot of books, cause depending on its mass, it can take some time.
Only from an outside perspective. Inside the black hole it’s already next Tuesday.
with a stronger blackhole next to your blackhole. just have a stronger pull.
its like how do u have bribed politicians not vote according to that bribe: bribe them with a bigger bribe.
Spaghettified... Mostly.
feed it taco bell
The singularity will pull you in, feet first, then the tidal effect will spaghettify you. You will be ripped apart atom by atom by those same tidal forces. You cannot escape the event horizon.
Good luck!
Perhaps op can escape in a form of electromagnetic radiation....
by entering a black hole nested in that black hole
Hmm. You might be causally disconnected from the grandparent reality, but you're technically still inside both child and grandchild.
isn't that a direct contradiction? If I'm causally disconnected from a region, in what sense am I "inside" that region? I am causally disconnected from the past, am I in the past? I am causally disconnected from regions of space that are expanding away from me faster than the speed of light, am I "in" those regions in any sense?
Magic
You just need water and magnets
You throw a big party in a place as far as your eyes can see. You call it the event horizon.
As a jet of energy, assuming you haven’t actually crossed the event horizon
