There is no theory that can prove that passing through a black hole can travel through time and space. Nowadays, a big topic of human research is how to travel through space and time. Some people say that as long as the speed of light is exceeded, one can gradually go back to the past, but it is very difficult to go beyond the speed of light. In the end, some people proposed how to To travel through space is to pass through the black holes in the universe.
The great physicist Einstein and or experience, they all believe that black holes can be used as a bridge to traverse, and such a traverse speed is simpler and faster than the speed of light, and finally there is a support for this academic Physicists said during the interview on the earth that the black hole is actually not a point, but a ring-type structure. That is to say, there is a relatively large space inside the black hole. There may even be a direct connection to another dimension.
However, there is another faction of people who believe that once humans really enter the black hole, they will lose their direction, because there may be endless darkness inside the black hole, and it will never be possible to escape after losing their direction. Humans will be trapped in it forever, and not only humans are also trapped in it, but also all things in the universe. This is different from a maze. There are mazes, but the black hole is just a dark mass, which cannot be seen clearly. East, west, north, south, up, down, left, and right, even if they found an exit, it was because of the strong suction that they couldn't escape at all.
The third theory refers to the fact that there is an independent world inside the black hole, and even another universe inside the black hole. The black hole we see now is the entrance to another universe, but there is still a lot of understanding and research about black holes. The downside is that people have no hope of entering the black hole, at least for hundreds of years.
