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

    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.

    Prerequisites: daughter

    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.

      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.

    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.

        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.

    Have 5D future humans put you in the tesseract, then you exit seeing your daughter on their deathbed while you barely aged a day.
