Black holes are at the center of the thing. 

Black holes are the first and the last objects in the universe, and that thing makes them so interesting. The thing that makes it difficult to search and observe black holes is that nothing can leave from that thing. And this is the reason why the black hole remains a mystery and everything we know about black holes and what happens beyond the event horizon bases theories and calculations. So there is no real proves about things, what we have thought as fact. 

When we are thinking about the event horizon, the point where the escaping velocity reaches the speed of the light, we might forget that there is possible the electromagnetic version of the "sonic black hole" at the front of the event horizon. The electrons or photons that are orbiting the event horizon and black hole would not allow photons or other particles to leave from that area, which is inside this whirl, where the speed of the particles is near the speed of the light. 

That means the object like an electron or proton would disappear before it falls through the event horizon, even it could otherwise escape from that area. But the most fascinating theory is that in the middle of the universe is the giant black hole and the most gigantic galaxy that we ever can imagine. 

The idea is that when the Big Bang happened part of the material that Big Bang released during that thing dropped in the black hole, which formed from the energy of the Big Bang. When somebody says that there is no galaxy because we haven't seen that thing. There is a possibility that the galaxy is formed by dark matter. 

But sometimes there is introduced theories that in the eldest galaxies the hydrogen of stars ended a long time ago, and the entire galactic structures like star clusters are turned to black holes. So if every star in the galaxy is turned into a black hole, that thing can make the galaxy invisible. When the first stars were formed they were blue supergiants, which used their fuel extremely fast. 

This process formed all other elements than hydrogen. The nuclear fusion inside the stars formed heavier elements. The first stars are exploded as supernova a long time ago. But maybe some of those stars remain as black holes, and that thing means that there could be stored particles from the first moments of the universe remaining near those black holes, and that thing makes them so fascinating objects.
