What will happen to humanity through cosmic black holes?

Black holes have always been the most mysterious celestial objects in the universe, and their huge gravitational pull can bend space-time, and no object can get rid of it, not even light, so black holes are super scary objects.

Black holes are shrouded by an event horizon, and space-time is divided into inside and outside the event horizon. The horizon of a black hole is a one-way channel, and anything can get in, but nothing can get out. Because black holes can't send information, we currently know very little about what's going on inside them.

We can't know for sure what exactly will happen to the people who pass through the black hole, but only based on limited guesses.

Black holes need to be discussed on a case-by-case basis because black holes exhibit different properties depending on their mass. For stellar black holes, which are only a few to tens of times more massive than the Sun, their singularity creates a powerful tidal action outside the surface, causing any object close to their surface to break down into atoms. Therefore, when people get close to this kind of black hole, they will be crushed to pieces and turn into atoms, and people will not be able to pass through stellar black holes.

If a supermassive black hole with a mass of at least hundreds of thousands of times that of the Sun is safe, it is safe outside the surface of the black hole and within a certain range of the surface of the black hole. Therefore, if someone passes through the event horizon of a supermassive black hole, he can safely enter the black hole. But what happens to this person after entering the black hole?

In "Interstellar", after the protagonist Cooper falls into Kagantuya's supermassive black hole, he is not killed, but enters the five-dimensional space. Of course, this is not to say that supermassive black holes are connected to the five-dimensional space, but that "they" put the five-dimensional space inside the black hole. Otherwise, as you get closer to the singularity, the tidal action will become stronger.

When close enough to the singularity, the human body is likewise torn apart into atoms.

In addition, a recent study showed that if someone falls into a Lesna-Nordström black hole, then, that person may have an infinite future instead of being destroyed by the black hole. However, this is only a theoretical possibility, and in practice we cannot go inside a black hole.

Humans are torn to shreds, or powdered, by tremendous pressure. Scientists have long studied that black holes have a huge attraction, oppressive force. As soon as an object approaches, it will be sucked in and will never be able to get out.

A black hole swallows everything, so a person who falls into a black hole may die, because there is no oxygen in the black hole, and a person cannot survive.

Humanity may be wiped out, and the attraction of black holes is too great for humans to necessarily survive in them.
