Feeling like taking a vacation.

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.
Spaghettified… Mostly.
With space time snapshot machine I guess, you setup space time snapshot machine to take snapshot and setup detector on your body particles to roll you back from snapshot after your every particle is altered and it rolls you back to previous state. I think this should work.
And never trust it when it says “quick save” always make a manual backup!
You just need water and magnets
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.
Does this also mean that black holes are totally indestructible?
Basically.
They slowly decay as hawking radiation, but there’s nothing you can do to speed up the process.
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.
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!
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…
feed it taco bell
Through the gift shop.
As a jet of energy, assuming you haven’t actually crossed the event horizon
Magic
One wouldn’t
You can eveporate your way out of it, given enough time.
Find the Myotrope, invert your orthocameral orbit, grab your ankles, and hold on!
You wait for it to reach a critical mass and explode. Might take a little while.
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=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.
They don’t. They do evaporate though.
You’re maybe thinking of white dwarfs. Black holes don’t do that.
depends how close you are, and not getting spaghettified.
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.
The good news though is that so does work. So does anything, really.
Well, the end of it is, at least.
So if you walk backwards, every direction leads out. Easy!

Exactly!
That’s the fun part, you don’t.
