Could the Schwinger effect in black holes be the source of mysterious Hawking radiation? Is there some outcoming radiation that comes out from the black hole? And could that thing turn the event horizon invisible? Could that outcoming radiation be the thing called "dark energy"? If that strange wave motion is coming from the fourth dimension. That radiation is invisible to detect. There is the possibility that dark energy tunnels through superstrings that are forming all elementary particles. There is a theory that black holes are particles. That is in the fourth dimension. The idea is that when a particle jumps to the fourth dimension or otherways saying energy level that means the fourth dimension. It leaves a hole behind it. That hole is the channel where the radiation from that fourth dimension comes from that super-high energy level. And the reason why we cannot see the singularity is that there is some kind of counter-radiation or wave motion that will pull energy fr
