On Emergent Curved Space-Time
typo I meant "isometry" not "isotropy" fixed below.
Also my theory explains 1. Why macroscopic physics is local even though microphysics is nonlocal. I explain the classical limit properly. Penrose points out that the orthodox explanation of that is a boondoggle. Classical physics is local only because the ODLRO vacuum order parameter inflation field is local! 2. Why the early universe has low entropy - i.e. signal nonlocality retro-causality as in Garrett Moddell's talk at AAAS USD i.e. Second Law of Thermodynamics Arrow of Time problem solved.

I think his main point is that for purely mathematical reasons GR doesn't generally admit true energy conservation principles, either in correspondence with Newtonian theory or otherwise. Perhaps, but it has no bearing on my paper. Jack, your model recovers GR -- with /\, of course. Yes, it explains WHY GR works and is consistent with all observations. It unifies the emergence of gravity with inflation in a bootstrap. The coherent phase modulation of the inflation field forms curved space-time. He points out that in order to write an energy conservation law for the Einstein field there must exist a timelike hypersurface-orthogonal Killing field, which is only true in certain special cases, such as the SSS spacetimes. Well known in every text book. The conclusion is that total energy and local energy density is not fundamental. What is fundamental is the tetrad field. What textbook says that this limits the validity of GR as a theory of gravitation? None. That's not what I said. I said the proper conclusion is that the Newtonian idea of local energy density is not fundamental. Wheeler says that. From Nother's theorem we know that energy conservation comes from time translation invariance violated in the expanding universe! The universe is obviously not time translation invariant on the large scale! The timelike Killing vector field isometry of some solutions to Einstein's field equation, not all solutions, is closest we can come to the Newtonian notion of energy conservation for the vacuum itself. When we write Tuv^;v = 0 That does not include gravity. It only includes the local non-gravity sources of gravity. The actual vacuum equation is Guv + /\guv = 0 where (c^4/8piG)/\guv = LOCAL RICCI Dark VACUUM Energy Stress-Energy Density Tensor (ZERO ENTROPY) What is NONLOCAL here is the WEYL CONFORMAL CURVATURE "VACUUM ENERGY" and only that has ENTROPY according to Roger Penrose. Note in standard black hole theory /\ = 0. Also note /\ is uniform and constant in standard 1915 theory. You need torsion fields, at the very least, to make /\ a local field for weightless zero-g warp drive and star gate time travel metric engineering. Locally gauge 4-parameter translation group to get 1915 GR with curvature only i.e. spin connection is redundant. Locally gauge 10-parameter Poincare group to get curvature + torsion with independent spin connection. Note that even in the exotic dark energy vacuum CONFORMAL =/= 0 When EINSTEIN + /\METRIC = 0 when /\(Dark energy) = 0 then EINSTEIN - RICCI - 0 See Roger Penrose's 3 books for details. i.e., Emperor, Shadows & On The Road. But I shouldn't speak for Waldyr on this. He should speak for himself. I think he is arguing that this means that the geometric model of GR should not be taken too seriously in terms of *physics* -- although of course he will insist on full rigor with respect to the *math* regardless. I doubt he means that. I seem to recall that he wrote something to that effect a while back. Maybe Waldyr should speak for himself here. I don't know what he means. Can you follow his 21 pages? Not easily. Z. My Ansatz is basically empirical. It's not a "theorem". It's a conjecture. It had implications for "quantum gravity". My theory is emergent bottom-up not top-down as in conventional quantization of gravity that fails! But I understand that Waldyr doesn't believe in Einstein's geometrical model as a direct description of physical space and time to begin with. Not relevant to the several new physics ideas I give in the paper that are relevant to enigmatic observations. In any case I would be surprised if that's what he means. Of course he also has purely technical issues with your paper that have nothing to do with physics. They are minor points about notations. He goes into irrelevant details fighting other battles irrelevant to my paper. I'm talking about his general motivation. John Baez can't even derive GR with spin foams - so what good is it? It makes great applied math to be published in journals on applied math, AKA contemporary spacetime physics. Who cares about "physical reality"? What the hell is that, anyway? Actually that's Niels Bohr's fault. Do you think maybe Bohr should have stuck to soccer? :-) Bohr should have stuck to psychology. Z. Z. Z.

He admits I think to "twenty". What this means is that Waldyr is applying an inappropriate standard and missing The Forest for The Trees. Also he pounced on an early hastily assembled rough draft and never once really addresses the physical ideas that ARE my paper.

Yes, I understand the general rule. I think you misapply it in the case of Penrose and Hawking. They are mathematicians who are ABLE to think like physicists! They are able to do BOTH modes. Well, what about this idea that a collapsed gravitational mass results in a curvature singularity at a point that is removed from physical spacetime, on the grounds that it is not technically part of a "manifold"? I would suggest that this is not the thinking of a physicist. Also that on hearing this someone like Feynman would have a fit. Z. |
