Feeling like taking a vacation.

You evaporate over billions of years via Hawking radiation.
Try more like trillions of trillions of trillions… repeat a few more times.
Luckily time flies fast inside.
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.
Well your information is preserved in the universe and that’s all any of us can really lay claim to anyway.
What if I have somewhere to be before then?
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.

Generally speaking, as Hawking Radiation.
what if i want to use my legs afters
You’d have to build them first.
Anything more complex than an atom is going to be disintegrated before it even enters a black hole due to the intense energies at play at the interface.
Anything as complex as an atom will be disintegrated too.
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.
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.
And anything without mass MUST travel at the speed of light
You’re not the boss of me! I do what i want!
You wait for it to reach a critical mass and explode. Might take a little while.
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.
Wouldn’t the hawking radiation need to be a higher rate than the black hole is absorbing matter?
Yes, the effect is extremely tiny and easily offset when a black hole is “feeding”.
Which will eventually happen to all black holes because the last things remaining will be black holes, so there would be no matter to absorb.
Which begs the question, what happens to the estranged particle that escapes the black hole from hawking radiation.
They’ll wander forever through an ever expanding space, meaning they probably won’t ever come across a different particle.
Eventually everything will reach equilibrium, aka the state where nothing moves anymore because everything it could react with is too far away to cause any reaction.
Which is why it would work with a small black hole, but not with a large one
depends how close you are, and not getting spaghettified.
Through the gift shop.
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.
So if you walk backwards, every direction leads out. Easy!
So if you walk backwards, every direction leads further in. Easy!
Exactly!
Vacation is seeming further and further away.
The good news though is that so does work. So does anything, really.
Well, the end of it is, at least.

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?
deleted by creator
That’s actually not that hard, if we’re talking about a rotating black hole that’s sufficiently large (like the supermassive ones are).
Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.
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 a white hole.
(not kidding)
One wouldn’t
You can eveporate your way out of it, given enough time.
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.
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.
