Some little details about black holes and the event horizon
Because we cannot see black holes, we cannot say that we know things, what is happening in that particle. The end of our ability to make observations is the event horizon, and after that everything, what we see is theory. Black holes are the tightest objects in the Universe, and that is what we know about that strange particle.
The Event horizon
The last time, when we see the object before it falls in the black hole is when it touches the event horizon. In that point, the speed of the dropping object would be the speed of light, and this means that the time would stop in the particle. And what is behind that point, what is called "Event horizon", is only theory, and we cannot know if the black hole would touch the event horizon, or is there some space, where the fallen object can travel to the center of black hole, because we cannot get observations from another side.
The thing what we would see, when we are dropping in a black hole is a mystery. We might feel that everything would be stopped and after that, we cannot imagine, what the world inside the event horizon would look like. Because time stops at the point of the Event horizon, we would feel, that we would be in that point forever, and actually, we don't know are we elding during that moment, what takes forever. But that is the thing, what we can think about.
When we are talking about black holes, we are talking about points or objects, where information disappears. That means that the information, what goes in the black hole would not come out, or we cannot see that information anymore. There is sometimes claimed, that the black hole would destroy material, and that is not true in the physical meaning.
If we would think that in the Earth atmosphere would forming the tennis-ball-sized stable black hole the thing would be, that this object would crush the form of the material. But the physical form of the material remains, but the entire planet would be crushed, when it would be pulled in the black hole. The molecules would be destroyed by the tidal forces, and that means that the molecular form of the material would be destroyed.
But atoms would remain. If the black hole would be supermassive, it can suck entire solar systems in it. There have been theories that the black holes might have solar systems, and the thing is that the transform disk around that object would give energy in a similar way as the regular star. And if the planet would orbit at enough big distance it would have lifeforms, but the X-ray radiation of the black hole would be very powerful, and that means the species must be more protected against that radiation than we are. But theories are an interesting thing.
