- TL;DR Summary
- Help grasp the concept that the universe has an age
Although I understand that time does not exist prior to the big bang, it's still a difficult concept that the universe - the sum of all that is and ever will be - has a beginnnig and therefore an "age." While we could say that time as a dimension began at the big bang, and it was meaningless before, is difficult for me to understand. Then there are the braneworld theories that indicate higher dimensional branes interacting which started our universe. I know we evolved on Earth so we are not selected to conceive of such things but I hope someone here can put things in persepctive for me and others.
