Sid:I don;t disagree, but how would that be a response to a question which is whether or not time had a beginning. Of course, in a sense, this question may not be decidable in our world, however, it is found that entropy increases with time in a closed system. If there were a time when there was close to zero entropy, then I suppose that this would mark the beginning of time.
Right you are. It is not a response to, did time begin; it was a response to Plato, from this thread. The original question was, “Does time have a beginning?” The purposes of my previous posts were to help define certain properties of time so that a much fuller explanation would make sense and would not entail a tremendous amount of quibbling over definitions. I will tell you that what I have said has as its foundation the arguments of Aristotle and Aquinas, primarily, and Kant and Bergson, secondarily.
Time is definitely a tough exigency to define or describe. To answer the opening question is to carefully and properly define what time is. Kant perceived time to be conceptual, i.e., in the mind only. Bergson went the opposite direction, investing time with a “fully real” status like “motion” itself.
But while Time is never without Motion it is NOT Motion, per se; for time is common to all forms of motion, local motion, quantitative motion and qualitative change. While each of these motions is transpiring, the same time is passing. All we need to do is look at our watches or clocks for verification of this. Furthermore, what we perceive is the same, not three different kinds of motion as regards time.
In our experiences with motion, we have discovered that motion can be faster or slower. A fast motion is one that covers a given space in a shorter time, while a slow motion covers that same space in a longer time. Notwithstanding the fact that faster motion tends to reduce the time it take to traverse a given space, while a slower motion tends to increase it, if we check our watches or clocks we will easily see that the same time is passing.
Now, if time were motion, our descriptions would have to be much different. We would have to describe, for example, a slower time as one that covers a given space in a long time, while a faster time would cover that same space in a shorter time. If that were the case, time would be measured by time, which is not so. However, time does not go faster or slower. Time is essentially constant and it is motions that go faster or slower.
Now, as is clear, time, though not the same as motion, is never without motion. Thus, if the universe had a beginning, as the majority of astronomers and cosmologists suggest, then time began at the instant the first motion occurred (which we assume is the instant of the big bang). However, this seems to be a point of impasse. Is the creation of the universe correlative with the eternal existence of God, or, could God create things, including the universe, at “times” relative to the beings that He creates and that can sense motion and thus time?
There is no question that trillions of things (and beings) have come to be at trillions of different “times” across the span of time of the universe. Is the Universe just another one of those trillions of things? Or, was the universe created in stages? Or, did the Universe occur at the “beginning” of eternity - in which case it should not be suffering the demise of entropy now?
