Age of universe at 26.7B years, nearly twice as old as previously believed
IANAP, but as a mathematician it seems extremely inelegant that there would be a start to the time dimension of the space-time object we live in, when we don't even know if the spatial dimensions are finite themselves.It is my understanding that the density of the universe billions of years ago was radically different from the one we now observe, and since density is intrinsically tied to our perception of space and time, wouldn't it make more sense that time actually stretches infinitely the further back we go, thus nullifying the concept of a beginning?I guess I'm having a hard time with the idea that space-time could be discontinuous.
