Sure it's 'self-evident' that the now I experience is present everywhere. But that self-evident truth was qualified by relativity, which was the actual great leap forward in our understanding of time. and experimentally proved > again - really? You can't even tell me how to measure "P-time" so I fail to see how any experiment has or can prove such a thing. If this is physical, scientific theory as opposed to a metaphysical speculation about "the eternal Now" a la Eckhart Tolle, then you *must* be able to provide some means of measuring your proposed physical quantity or entity. Again I ask: how will you prove this sharing of a moment other than by blustering that it is "self-evident"? > that they can be in the same present moment even if their clock time t > values are not simultaneous.

In some sense, all things happen Now and nothing will ever occur anywhere except Now and we all share it. That's the Now of Eckart Tolle's "The Power of Now". The problem is when you try to insist that this is a concept relevant to physics. Let me ask: do I share the "Now" with you as you were an hour ago? Do I share the same "now" as Caesar at the moment of his death? In the metaphysical sense, maybe. But not in any way that is relevant to physics and measured time. *Which" moment are we sharing if not a moment we can measure with a clock? If you just say "the current present moment, for goodness sake!" you are merely demonstrating that your concept is a tautology. > Your last paragraph fails because it is all about measuring CLOCK time, > not P-time.

It sounds *just like* good old clock time did in Newton's day! In fact just like our natural, naive intuition of time before an immense amount of deep thought and hard work on Einstein's part revealed that intuition to be mistaken. > extends happening occurs within the present moment and the current state > of the universe in continually computed.

If P-time can be calculated from the "curvature of the universe" (itself problematic, since space-time is warped and curved by gravity and is not a simple sphere), then what units will result? P-seconds? Is there any way to convert P-seconds to normal, good-ole clock seconds? If there's no use the P-time measurement in any other equation with other physical quantities such as time, distance, mass etc, then one has to wonder what on earth good it is. > Edgar > > > > On Saturday, December 28, 2013 8:33:23 PM UTC-5, Pierz wrote: >> >> Everyone else has made excellent, well laid-out arguments against your >> position Edgar, but I will throw in another perspective.
