There is a model that a black hole is a group of particles that are whirling or rotating in a warp bubble. In gravitational models, gravitation is radiation, the sender is so small that it travels through particles and pulls them in the smaller size. In that model, a hypothetical graviton is an elementary particle that sends a very thin superstring. The superstring pulls the quantum or Higgs field from the elementary particle. And that pulls its shell near to the center of that particle. In some models, the black holes have two event horizons. The outer and inner event horizons deny seeing things that happen in the heart of a black hole. The event horizon is the place where the escaping velocity reaches the speed of light. And at that point, the photons are whirling around the black hole. The inner event horizon is the point, where the escaping velocity reaches 2X the speed of light. And if we think about the light cone and the hypersurface as the event horizon. We can think. That th
