    But where are they coming from and going to if matter and energy cannot be destroyed? Appear and disappear just means they merely become detectable/detected?

      Think of particles as bundles of conserved quantities like charge, energy, mass, etc.

      In interactions, these quantities can be shuffled around and re-bundled into different particles—but the re-bundling isn’t creating or destroying the conserved quantities themselves.

      From nothing. No new energy is created because virtual particles are always created in a way that does not disturb the total energy of the universe. For example, one particle and one anti-particle. It can’t be any other way.
