WebbIt is argued that essentially all inflationary models lead to (future‐)eternal inflation, which implies that an infinite number of pocket universes are produced. Although the other pocket universes are unobservable, their existence nonetheless has consequences for the way that we evaluate theories and extract consequences from them. Webb5 juni 2012 · I'll sketch one of the eternal inflation variants: "false-vacuum driven eternal inflation". The idea is that you start with a spacetime manifold, on which is everywhere defined some scalar field. The scalar field ensures that whole region undergoes inflation.
