How strong must an object at the center of the black hole be to withstand the pull of the black hole and escape the black hole?

In fact, the object we are looking for must be strong enough to withstand and escape the drag of time without reaching the future, for example, not reaching eight o'clock tomorrow morning. This is a serious answer to this question.
We know that once an object crosses the black hole's event horizon to reach the "center" (i.e., singularity) of the black hole, it no longer exists in the original universe. (In fact, this isn't true.) However, it has inevitably lost sight of us in the future.
The strength of the object does not help. Within the event horizon of a black hole, you're basically in a collapsing little universe. All the paths to the future ended at that strange moment. From the moment you enter the interior of the event horizon of a black hole, it already heralds the end of time. After that moment, time itself ceases to exist.
The more you struggle, the faster you get there: the path with the longest "intrinsic time" (i.e., time measured relative to the traveler's stationary time) is the inertial path, that is, the path without acceleration. So, before the gradient of the gravitational field gets bigger and bigger, so much so that tidal forces tear you apart (the famous "ramen effect"), enjoy the beauty as much as you can.
Is this an old speculation, or is it a reality? Theoretically, any matter that enters a black hole is torn apart by an infinite force, and all particles disappear into infinity at the "singularity" and never come back.

In fact, it's a ring-shaped active galactic nucleus whose gravitational pull is so strong that all objects are shredded during their entry (once the object reaches a certain size or speed), and the resulting particles are blown back into space in jets from the poles of the "quasar." The reality is largely the opposite of the old mathematical model.
In the center is "will cut point" or "Z-hoop", where two spirals meet and rotate around the ring (the spiral of the jet is generated), which is probably the hottest place in the universe! Even in the face of overwhelming evidence, it will take a long time for human perceptions to change. So it could take decades to argue before the Big Bang and black holes finally calm down. But in the long river of time in the universe, decades of time is hardly a blink of an eye.
Therefore, only particles with intrinsic energy will fall into the black hole. Once inside the center of the black hole, nothing can escape. Regardless of the strength of the object, since nothing can withstand the tidal forces outside the accretion disk (or even the nearby spatial structure), then nothing escapes from inside the black hole. Anything but particles with little or no mass fall into a black hole. Therefore, it is impossible to escape from a black hole. There is no doubt that when a black hole erupts and is surrounded by a whirlpool or whirlwind, it does not spew out material like an active volcano.
In the accretion disk of a black hole, escaping from the extreme gravitational pull of the black hole requires a greater speed than the speed of light, and even light cannot escape from the accretion disk on its own.

Nothing escapes a black hole. The tidal forces produced by star-sized black holes can tear almost anything apart. Large black holes at the galactic level are milder, and a person can enter them without being pulled into "spaghetti" — but still can't leave.
While the "singularity" at the center of the black hole is likely to invalidate general relativity, we still predict that there are strong force field gradients in the black hole that can tear most things apart.
Can it withstand the pull when it falls into a black hole?
The gravity at the center of the black hole gravity well is zero. All you need is enough strength to reach the center of the gravity well. When you arrive you will become the heaviest thing in the Gravity Well. You just need to have a higher intensity than everything else in the area.
It is impossible to escape in this case.
When planets or other black holes are drawn into gravity wells, their surfaces are torn apart. Therefore, you need to be at least as strong as the gravity that can hold the surface of the star.
Unless something is colder than the energy in a black hole, no matter how powerful it is, it cannot withstand the gravitational pull of a black hole.
