Well balanced article. Time for me to take a nap now... or maybe I'll wait and do it later... maybe I already did and this is just a dream ... in any event 'be here now' pal.

Time appears to be inextricably linked to matter/energy. According to Einstein time is relative as is space.

My thesis is that time is a function of energy. Without an energetic universe, with heat or energy dissipation (they are synonymous) there is no passage of time. Once all the heat in the universe has been dissipated and its entropy reaches zero, then time will have stopped. This defines time as the measure or perhaps a "measurable thing related", to or of, the "average rate of change" of energy within the universe. That it seems to have universal units is illusory. Einstein demonstrated that time passes differently depending on gravity, speed and ultimately available energy. How it passes in black holes is a matter of conjecture. We can think of the changes within the universe, i.e. its movement measuring time itself. These changes are what give us the sense of the passage of time. Therefore time and change are inseparable. Energy and change are inextricably linked, and therefore, so is time to this.

To demonstrate this by thought experiment, try to imagine how a neutral observer would construct a clock to measure the passage of time when all the atoms of the universe have finally slowed down to a near dead stop. His "pendulum" for instance would perforce be as slow as the molasses. If everything had stopped moving, except the clock, it would measure nothing was happening between its ticks of time. Rather boring concept of time. If nothing changed anywhere between the artificial ticks of time, then time would measure a dead stop of all things. In effect time would be stopped as well.
