How to escape the gravitational pull of a black hole?
The answer, not hastily, is that it must be similar to being able to withstand and escape the pull of time, like something at 8 a.m. tomorrow morning.
You see, once an object passes through the event horizon of a black hole, the "center," or singularity, is no longer a location in space. (In fact, this is never realistic either). Rather, it is an inevitable future when.
Forces have nothing to do with this. Within the event horizon, you're basically in a pocket universe that's collapsing. All future paths end at that peculiar moment: for the interior of the event horizon, that moment is really the end of time, beyond which time itself ceases to exist.
The more you struggle, the sooner you get there: the longest path at "proper time" (i.e., time measured by the traveler) is the inertial path, that is, the path without acceleration. So, before the growing gradient of the gravitational field becomes so powerful that its tidal forces tear you apart, indulge in the scenery (like the famous "spaghetti").
In the old theory? Or in reality? In any case, in theory, all matter is infinitely powerful, because all matter is pulled apart in the process of entering, and its particles disappear to the "singularity" of infinity and never come back.
In fact, it is a ring-shaped active galactic nucleus with infinite strength because all the material is pulled apart during the entry process (once it reaches high mass/velocity) and its particles are blasted back into space in polar quasar jets. Therefore, it is diametrically opposed to the old mathematical artefacts.
At the center is the "spike" or "z-hoop", where two spirals around a ring-shaped object meet and travel around each other, (giving the jet helix found) probably the hottest place in the universe! Even in the face of overwhelming evidence, it will take a long time for human cognitive beliefs to change, so it could take decades for the Big Bang and black holes to eventually be buried. But this is hardly a blink of an eye in cosmic time.
Therefore, only what falls into a black hole is a particle with intrinsic energy. Once inside the black hole, and certainly in the center of the black hole, nothing will escape. Strength and durability have nothing to do with it, because if nothing can resist the tidal forces generated by its accretion on the outside, even the nearby spatial structure, then nothing will escape from the inside.
Nothing but particles with so little mass to no mass can fall into a complete black hole. Similarly, escaping from a black hole is impossible. This is even less likely than something surrounded by a whirlpool or tornado to escape during an active volcano eruption, which is almost impossible.
To get rid of the extreme gravitational pull of the black hole's accretion, you need to go faster than the speed of light. Even light cannot escape from accretion on its own.
Nothing escapes a black hole. A star-sized hole creates a tidal force that can tear almost anything apart. The big Milky Way black hole is fairly gentle, and you can get into a black hole without "spaghetti" — but still can't get out.
The central "singularity" is most likely the product of the incompleteness of general relativity, but it still suggests that there may be strong gradients there, and almost everything will be torn to pieces.
Can it withstand tension at its most central?
The force at the center of the gravitational well is zero. All you need is to be "strong and durable" enough to get to the center. Being there means you're the heaviest of all the people in that well. You just need to be "better" than anyone else in the range.
Escape is impossible under these premises.
At least as durable as gravity and the surfaces of stars, planets, and other black holes that are pulled into it, their surface torn apart, and pulled into a whole!
Nothing, no matter how powerful, can resist the gravitational pull of a black hole unless there is something more "cold" than the energy in the black hole.
