October 7: Thoughts for the Day

On September 26, I wrote a screed on the subject of time, asking an absurd question as to whether it possesses any physical properties. Since I wrote it, I have continued to ruminate about physical properties of time. I conclude the passage of time manifests itself, physically, in the changes that take place in entities subject to its passage.  Consider the way in which astronomers determine the presence of black holes. They do it not by observing the objects themselves, but by imputing their influence (e.g., their gravitational pull, etc.) on objects around them.  So must it be with time.  We cannot see it, but we see what it does. This idea may not be new, but looking at time from this perspective is new to me.
