Was there a beginning in time? What happened in the eons upon eons before then?
Funny how we can imagine time having no end, but it’s difficult to imagine it never having had a beginning.
What's fun is when they start talking about creating an entire universe in the lab, one that is just as large as ours, has just as much matter in it, and one that will hyper-expand just as rapidly ours. But don't worry. It won't hurt us. It'll make its own space as it goes through its Big Bang period and not intrude into ours.
Think of time in the purely scientific form. You can determine the time between two events if you know their coordinates and the velocity of propagation. This statement has no meaning if you take away the coordinate system. You can't measure the time before events before the universe was created unless you strictly assume that space existed before the Big Bang into which our universe expanded. Saying 'before' attributes more characteristics to time than have been defined by science.
