I have a question for the bright minds here. I have often wondered if spacetime has been constant thoughout the universe or if there are places where spacetime breaks down. One of these points I often imagine about is the very origin point of the Big Bang. Does anyone know of any papers addressing this question or have any input? Basically I am wondering if the age of the universe would be the same at all points in space, in particular from the very origin of the inflation. In my imagination this point seems a likely spot for the source of dark energy, and I often wonder if I could build a spaceship and fly to one of these points of inflation or dark energy would time exist there as we know it?
