Black Holes are So Much Fucking Scarier than you probably think they are
So, everyone has at least heard of black holes, abominations of gravity whose pull is so strong that nothing can escape. But that description actually undersells the true horror of what a black hole really is, and how you'd experience falling into one.
You might have heard that not even light can escape a black hole, and because light is the fastest thing in the universe that means they're impossible to escape. Its easy to imagine the gravity of a black hole pulling you down incredibly hard so that you can't jump away, but that's not exactly what's happening.
Imagine that you have a science fiction magic spaceship that can accelerate arbitrarily hard in any direction, and even travel faster than the speed of light. Since you know that the escape velocity of a black hole is the speed of light, you feel secure that your magic spaceship can rocket you away from any pull of gravity. To make doubly sure that you don't get lost you bring an instrument to help you navigate. This instrument measures the gradient of the local gravitational field, and points towards wherever the gravity is strongest, so that you can always tell which way is "down", towards the black hole.
So, with your magic spaceship and black hole compass you allow yourself to fall into the black hole and have a look around. Hopefully you picked a supermassive black hole so that the tidal forces just beneath the event horizon are relatively mild, so your spaceship--and more importantly your body--isn't torn apart. After you've made your observations and are satisfied, you decide its time to use your magic spaceship to head back out of the black hole.
There's a problem though, your gravitational gradient instrument that was supposed to tell you which way was down into the black hole is spinning wildly, seemingly randomly. It is profoundly unclear which way is out, and which way is further in. Maybe you decide no matter, you'll just pick a direction and see what you find. If you fire the engines of your magic space ship you find that the needle now points down in the direction you're traveling! So, you do the logical thing and turn around and try again, except to your horror the needle swings around to once again point towards where you're going.
Black holes don't just pull really hard, they distort spacetime until its normal geometry doesn't really apply any more. Inside the event horizon of a black hole, spacetime is so warped that the space and time components essentially switch places. Instead of space being stationary, and time flowing ever forward, in a black hole the intense gravity makes time slow towards a stop, while space is pulled inexorably towards the center. The singularity of a black hole isn't so much point in the center of a black hole as it is a final moment in the future of time. The event horizon is the boundary of the area where all worldlines--all trajectories it is physically possible to follow through spacetime--end at the singularity. Within the event horizon the singularity isn't a location in space, it is an inevitable moment in your future.
This means that if you're inside the black hole's event horizon, the direction of "out" simply does not exist.
Every direction is deeper in.
There is no angle you can rotate to that is out, that direction was closed off to you when you crossed the event horizon.
If you want to live as long as possible before you hit the singularity, you're actually best off doing nothing and simply allowing yourself to free fall. Because all directions are further in, attempting to accelerate in any direction will only send you deeper in faster. You might explore more space, but you'll live for less time.
Black holes are pocket dimensions pinched off from the rest of the universe where the door closes behind you as soon as you enter. There is no exit, and trying to find one only gets you more trapped.
