Time is ever perplexing. Some physicists give weight to the alternate universe theory, saying that alternate universes are breaking off in every moment. So why are we in this one? lol. We do know from Eisensteinian physicis that time travel is a normal part of our universe. A small change in your velocity (walking across the room) suddenly changes the 'time slice' you are in (over vast distances) by millions of years.

Another mystery of time is our ability to change our experience of it. The deepest spiritual experiences of god (or whatever) across all religious traditions describe a feeling of 'timelessness'.

So what is time? Who knows! I'll continue to explore this through both science and meditation :) Thanks for sharing!
