You evaporate over billions of years via Hawking radiation.

    Generally speaking, as Hawking Radiation.

    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.

    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.

    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.

    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=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.

    Wouldn't the hawking radiation need to be a higher rate than the black hole is absorbing matter?

    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.

    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.

    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.

    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.

    You'll be slowly radiated out one half of an entangled pair of particles at a time. Arranging for reconstruction might prove difficult.

    Are you capable of moving faster than the speed of light?

    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.
