Don't take "virtual particles" too seriously. Quantum Field Theory for a single (non-interacting) field is quite easy to solve. One of the things that can be calculated is the Feynman propagator $G_F(x,y)$, wich describes the probability amplitude for the propagation of a particle from spacetime point $x$ to spacetime point $y$. Obviouslly, the Feynman ...

Virtual particles are not real. They come, as I've said in many answers on this site, from a naive interpretation of Feynman diagrams which should not be taken as an actual, exact description of how the physics works. The actual description of an interaction in the quantum field theory is more complicated than "photons are exchanged". In particular, ...

Lots of questions here, I can answer a few of them. The question might sound very easy - Hawking radiation, however I was pondering that as you get closer and closer to a black hole, time dilates exponentially where the surface of the black hole is "timeless". So how can anything even anti-matter destroy a black hole if it cannot touch the ...

The popular description of Hawking radiation with one a particle from a virtual pair falling in and the other escaping is just a pretty picture, "in another model, the process is a quantum tunneling effect, whereby particle-antiparticle pairs will form from the vacuum, and one will tunnel outside the event horizon." In fact, one does not even need the first ...
