The The existence of black holes was first predicted in 1916 by the German physicist Karl Schwarzschild., based on Albert Einstein’s equations of general relativity. Since then, scientists and space enthusiasts have been obsessed with finding out what’s inside.
Based on current theories, the interior of a black hole is an incomprehensible place for human beings. Gravity is so strong that not even light can escape, which means we can’t see anything inside a black hole.
However, we can make some assumptions about what might be inside a black hole. Scientists who are experts in the study of these objects have theorized that one possibility is that within these stellar regions there is empty space, with a singularity in the center. This singularity is a point of infinite density, where the laws of physics break down.
Another possibility is that the interior of a black hole is a parallel universe. This is based on the idea that black holes could act as portals to other universes. It sounds crazy, but the window of possibilities is really wide.
If we could see inside a black hole, chances are we would witness something very strange and unknown. Gravity would be so strong that anything entering the black hole would be crushed and destroyed.
It is also possible that we saw some kind of quantum effect, since the laws of physics change inside a black hole.
The only way to know what is inside a black hole is to go there and see for ourselves. However, this is something that is impossible for humans, since the gravity of a black hole is too strong for us to escape.
In any case, we have this illustration that shows animatedly in a video, what it would be like to go inside a black hole.
