Agujeros negros la frontera del conocimiento

Black holes hide a lot of information about what's inside them. Stephen Hawking discovered that something called Hawking radiation can actually come out of a black hole. This created a problem because it goes against what we thought we knew about black holes. From the outside, you can't tell what is inside a black hole. When you look at a black hole, all you can tell about it are its mass, its charge and its state of rotation. And that's the same for any black hole, no matter what it was made out of. This means that a black hole contains a lot of information that is hidden from the outside world. That was a very weird thing for people to get to grips with and then Stephen Hawking made this amazing discovery of Hawking radiation that says actually stuff comes out of a black hole. And that's where the problem really started.
