(I'm expanding on the comment by Jason.) The "P-time" notion, if it means anything at all timelike, says that there exists some uniquely correct ordering of events across space.
Consider these events: Pam's 3rd birthday party and Sam's 4th birthday party The "P-time" notion says that either (A) P3bp happens before S4bp, (B) P3bp happens after S4bp, or (C) P3bp happens at the same time as S4bp. The "P-time" notion, having not developed in a scientific manner, can't offer any help in discovering which of A, B, or C is the case; it merely says it is the case that, in principle, exactly one of A, B, or C is true. By contrast, the past century of physics concludes that A is true in some reference frames, B is true in other reference frames, and C is true in other other reference frames. It is NOT the case that, in principle, exactly one of A, B, or C is true. So there's a direct contradiction. And "P-time" falls on the wrong side of the contradiction according to a whole century's worth of experimental work in physics. Furthermore, there is (scientific) theoretical work (c.f. http://www.sciencedaily.com/releases/2012/10/121002145454.htm ) that indicates that, by exploiting quantum behavior, we should be able to build a superposition of one causal order and the reverse causal order between two events in the same location. If that pans out empirically, then the "P-time" notion won't even have the appearance of being a local approximation to the truth. -Gabe On Thursday, January 2, 2014 5:19:52 PM UTC-6, Jason wrote: > > Edgar, > > I realized there is another problem.
