Here is what I think I understand about time as it relates to the question of “did the universe have a beginning or has it always existed?”. This thread is open for discussion on the topic. I see time as a continuum of “nows”, i.e. a continuum of points in time, Zeno and all. If there was a beginning, and if you could go backward in time to along the continuum toward the beginning, you would always be at a point on the continuum of “nows” until the beginning point on the continuum which would then be the first “now”. Each point marks a time event. If there was no beginning and if you could go backward in time forever you would always be at a point on the continuum of “nows”. No matter how finely you divide a moment of time, time still passes. There is always a finite length of time between any two points on the continuum. I do not see the logic in saying that if there was no beginning we could never get to now. Someone I know believes it is that way. I believe that you are always at a point in time and there could be an infinite continuum of “points in time” or there could be a finite continuum of “points in time” depending on if there was a beginning or not. We can’t tell if the continuum is infinite or not from where we are now and we can't tell if there was a beginning or not just because there is a "here and now". But this forum acquaintance doesn’t believe that it is possible for the continuum to be infinite and that is a different story. He says that if there was no beginning we could never get to the present. What do you think? Comments welcomed.
