← Hints of structure beyond the visible universe

rebelest; speed of light in vacuum is a limiting velocity for travel within spacetime; spacetime itself can stretch much faster than that (there is no limit, really). If inflation is correct, which at the moment sort of hangs in the balance, that is what happened. Nothing actually travelled through space; the universe itself inflated at enormous rate until the scalar field driving that inflation collapsed.
