baywax said:Time is our measurement of change. Both time and change are products of energy. So, if we can define energy as "non-physical" that may suffice.
However, energy is described by Einstein as equaling mc2 (mass at the speed of light/squared) and as far as I know mass is a physical state. So, when the "ultimate" motivator, energy, is agreed upon to be physical, what is there left to designate as being "non-physical" since, figuratively speaking, energy is the common denominator for the entire universe during all its stages.
Let me ask the question a different way...if time is a physical thing as you suggest, what are the physical properties of time?
Can you provide a link for this?
