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.
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?
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.
You don’t.
Are you capable of moving faster than the speed of light?
Maybe my farts are
Real
Pretty sure even that wouldn’t work? Once inside all directions become further in, or all futures become further in, or some bullshit like that.
But travelling faster than light you can go to the past before you passed the event horizon.
Doesn’t matter once your breaking constants
or have a time dilation device from sg1, that is modified by replicators
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.
Well, the end of it is, at least.
The good news though is that so does work. So does anything, really.
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.
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.
And anything without mass MUST travel at the speed of light
You’re not the boss of me! I do what i want!
One wouldn’t
You can eveporate your way out of it, given enough time.
You’ll be slowly radiated out one half of an entangled pair of particles at a time. Arranging for reconstruction might prove difficult.
Through a white hole.
(not kidding)
since black holes are incredibly common in the universe, if everything that went into a black hole came out the “other end” from a white hole, then it would logically follow that white holes would also be incredibly common. however, while white holes might exist, nobody has ever observed one, or found any mechanism capable of creating one, or evidence suggesting that they even exist, or have ever existed, or will ever exist. meanwhile, we have directly imaged the accretion disk around a supermassive black hole.
one definitely exists, the other is firmly within the realm of theoretical only, where it is expected to stay indefinitely.
To be fair, we only recently actually saw a black hole, and before that, it was just assumed to exist by its gravitational effects.
Or if every Universe begins with a white hole, you now have a set of keys to the Multiverse.
Through the gift shop.
That’s the fun part, you don’t.
Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.
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.
Now I have a doubt. Could you have a stable orbit around the singularity but inside the event horizon? Or is the orbit speed above c?
Maybe you could live a comfy life there.
I would assume that anything that lies within the photon sphere could never have a stable orbit. The photon sphere is the point that light itself orbits the black hole and its 1.5x the radius of the blackhole itself. Anything closer to the singularity than this boundry is doomed to fall into the singularity as it would require faster than light speeds to maintain any stable orbit.
I wonder if anything could actually cross the photon sphere at all without getting vaporized by potentially billions of years of accumulated light that got stuck orbiting the black hole.
Hell, forget the photon sphere, even. Know that jet of energy black holes are thought to sprew out at their poles due to the material falling in to them? Imagine what that material is doing inside the event horizon. Whatever it is, it’ll be pretty violent, enough to call the moon slamming into the earth “relatively peaceful”. It would probably be more pleasant hanging out in the core of the sun than even an AU away from a black hole’s event horizon (and I mean on the outside).
Also, the event horizon is where light cannot escape. The “spacecraft event horizon”, or the orbital plane surrounding a black hole where a spacecraft couldn’t escape it is going to be much farther out, unless we can figure out ftl travel.
If I recall correctly, the photon sphere orbit is unstable, so there may not be a ton of photons there. “Unstable” in this sense means that photons in adjacent orbits tend to diverge away from the photon sphere orbit rather than toward it.
For Schwarzchild holes, the lowest circular orbit for massive objects is at 3 event horizons, which is above the photon sphere. There are unstable circular orbits down to 2 horizons. Black hole rotation reduces this altitude for prograde orbits asymptotically down to 1 horizon.
…which is why you need technology so powerful it can protect you from a singularity.

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).
