Hawking argues something like the curvature of spacetime is analogous to the surface of a sphere: - where's the beginning of the surface of a sphere? Similarly, where/when is the beginning of the universe/spacetime? Maybe more to the point is that questions like that of the OP require definition to be meaningful, and usually when you define the terms, the question has disappeared. Without definition there can be no understanding of the question; it becomes a nonsense question. — tim wood
That is the price you pay for holding substance views of space-time, as if space and time were transcendental tape-measures being aligned to a table-universe.
So why not simply reduce talk of time to measured intervals between events? For presently observed change does not require a background notion of temporarily if one accepts present change as irreducible and fundamental. — sime
Time is real. I have an argument in favor of it in here. — bahman
How could something always have existed? How could nothing exist, and then something come from nothing? — CasKev
I have been struggling with this problem for a while. It is difficult for me to even explain it to you. Lets assume that universe has a beginning. There is however no before before beginning which means we cannot possibly define any reference point to measure the beginning from. This means that the age of universe can be anything which is paradoxical. — bahman
