Was there a beginning to physical time?
I do not think that there could be a beginning of time. If we look at time as going forward, then we see it moves within the confines of a linear fashion. This is because of time, at least in our perspective, of having a “now” (present), past, and future. If we look at an instant however, we can see that it has no real duration. A duration of an instant is always a fabricated measurement by us. Time then is just our perception of change (whatever that actually is) from instant to instant. This would mean then that for physical time to be real it would have to have these instants be connected. This would imply there is a point of contact between the past and now, along with now and the future. If they were connected though, how could any change actually occur? Since an instant has no real duration though how could physical time continue? It seems then that time is only real due to our subjective nature of it. Since it is not real then how could it have had a beginning?
An easier way of looking at this questions is by saying, okay, there is a beginning of time. This for instance could be the Big Bang, but as soon as we have discovered this “beginning” we can right away ask, what came before that? Thus, this idea of a beginning falls flat on its face. In terms of questions then, asking if there is a beginning of time becomes a pointless question.
