""Can something appear from nothing?", to which, I replied "Actually, yes, particles are known to appear in vacuum. It is called the 'Casimir Effect'"."

Zonder, the "nothing" in a vacuum is different from the nothing that existed before the universe came into being. Any particle that appears in a vacuum came from somewhere else in this universe, I think, which is distinct from a particle that appears in the void that existed before there was a universe. The latter particle would truly come from nothing, whereas the former appears out of "nowhere" but is of this universe. So when it is said, something appears from nothing, that is not exactly correct unless that "something" is a new addition or mass that did not exist in the universe before. Is that correct? I love it when you share your physics knowledge.
