Virtual Particles in Quantum Physics are particles that can form in any place, including a vacuum, and are created in a pair of particles opposite each other, and are usually eliminated. When these particles are formed on the horizon of a Black Hole, Hawking radiation occurs, when one particle falls into the black hole, while the other escapes. The particles are supposed to have 0 energy, and since one exists and continues to affect things around it, the black hole must lose energy.
My explanation with reverse time travel for this is that the particle that now exists is a particle that previously in the black hole, and escaped through reverse time travel.
To begin, first visualize a road that curves as below:
(Equal signs and "Arrows" represent roads, .s are placeholders)
If your point of view cuts through the middle of the road, than there is three roads, and in your point of view, there is indeed 3 roads, and no way to disprove it. If your point of view moves along the right, two road merge into each other and disappear, while one continues.
Basically, imagine the first the first two roads happening within the black hole, and you moving to the right with a vertical line as moving through time with one slice of space. "Virtual particles" appear at the second turn in the road, and at the first turn, the mass inside the black hole and one of the virtual particles eliminate each other, while the other virtual particle escapes.
To a person which looks at the whole road, it's a single road bending back and back around on itself. Likewise, to a fourth dimensional being (with time being the fourth dimension), they can see that it's only a single particle going back through and around time to escape the "inescapable" gravity of the black hole.
P.S. Self eliminating pairs of virtual particles would just be circles in time-space.
P.P.S. Since virtual particles are in antimatter and matter pairs, perhaps particles travelling back through time have reversed gravity and reversed charge?
So basically, the question is "Is this possible?" and "If so, why would this happen?" , and "Does it have any Implications?
(Tell me if this should go on Physics instead, I was thinking that this was a bit too Sci-fi-ish)
