Of course, if you want to interpret what I'm doing as Physics, it is totally amateurish - in fact avowedly so, since it is a major consideration of mine to keep things as simple as is possible, consistent with making the point. You are making them simpler than is possible and also making some false statements about General Relativity. There has been some sloppiness on the informal language surrounding the EEP. This is Paul Zielinski's key point, which, however, he over state IMHO as "there is no General Relativity" etc. The curvature tensor is a local observable. If it is not zero at a point it is not zero in all local frames at that point. In that sense you cannot say that spacetime is EXACTLY locally flat. What is meant by EEP is that the geodesic deviation tidal acceleration can be made arbitrarily small in the sense of the epsilon-delta algorithm for the continuity of functions in calculus. That is, given any curvature detector resolution (inverse bandwidth) epsilon, one can find a scale L for the size of the timelike geodesic LIF at event P such that the relative curvature tidal acceleration delta, between two neighboring geodesic test particles separated by L, is smaller than epsilon. This algorithm breaks down under two conditions: 1. Approach to a singularity. 2. L ^2 Lp^2 = hG/c^3 No matter how many obsolete quotes from Einstein, Eddington, Bergmann Paul brings up from the early days does not change the fact that the above is the proper way to understand EEP. Similar picayune objections can be made of any great theory. At most they warrant minor footnotes in the evolution of the understanding of the theory at the informal language level. The Yilmaz problem trying to localize the energy of the pure gravitational field is a bogus problem as explained in Chapter 20 of MTW. It is asking the wrong question. The problem there is the global one of defining a total 4-momentum Pu and a total angular momentum Muv for any gravitating system. First note that Pu and Muv are NOT local Diff(4) tensors. My remarks about recasting Einstein's local field equations as the simple detailed balance of ALL stress-energy density currents, i.e. Sum over i Tuv(i) = 0 IS Einstein's local Diff(4) tensor field equation i = "Marble"(Geometry), "Wood"(On-mass-shell matter, far and near EM fields), exotic vacuum fields, torsion fields, dilatation field, non-metricity hyperspace fields - is a DIFFERENT PROBLEM from the problem in Ch 20 of MTW which deals with special global properties of ASYMPTOTICALLY 4D FLAT SPACE TIMES relevant to the detection of gravity waves. This is not the same as the large scale FRW 3D spatial flatness where Omega = 1 result of inflationary cosmology relevant to the discovery of dark energy + dark matter as ~ 96% of all the "stuff" of our local brane world that we are stuck on as surely as Eddie Abbott's "Flatlanders" and Dean Swift's "Laputans" :-). O Brane New Worlds that has such M-theory in IT FROM BIT + BIT FROM IT. Where in general the result of the metricity zero torsion Bianchi identities Tuv(Geometry)^;v = 0 BREAKS DOWN is the necessary condition for METRIC ENGINEERING, i.e. bending the geometry of spacetime to our will and desire like Q in Star Trek in a "soft way" not via the brute force (String Tension)^-1Tuv*(On-mass-shell matter, far and near EM fields) term, which we ignore in practical metric engineering unless we can lower the string tension. Sorry typo corrections in this version, the most important one is X = (c^2/g)cosh[g(Ship Proper Time)/c] cT = (c^2/g)sinh[g(Ship Proper Time)/c] Refuting Hal's theory here is important because Nick Cook's book hypes Hal's theory and the related theory with Haisch as a viable program to advance Space Science. Hyping vaporware is big business these days as we also see in NOVA's "Elegant Universe" with Brian Greene. However, there is a big difference. I think there is a lot of value in string theory and its extensions M theory to parallel brane worlds. I do not think that Hal's approach will ever bear fruit in terms of "Metric Engineering" the zero point exotic Dark Energy/Matter resources of Super Cosmos in our quest to Make Star Trek Real.

Feeling that the criticism was less than fair (and given the fairly close correspondence between Yilmaz and PV), I wrote to him saying he was missing the point, namely that (whether PV is true or false) between Yilmaz and PV we could begin to see gravity as emerging from an intelligible physical system. I do not understand what you mean by "between Yilmaz and PV we could begin to see gravity as emerging from an intelligible physical system" That is very vague. Also what is, in your terms, an "intelligible physical system"? "Intelligibility" like "beauty" is in the mind of the beholder relative to the beholder's depth and level of understanding of the issues. This is an unending process of course like an infinite sequence whose perfect limit we can never attain. Taking the Einstein - Weyl - Wigner - Bargmann - Schwinger - Utiyama - Kibble ... path. 1905 Special Relativity later made into elegant 4 dimensional rigid metric geometry x'^u = Lv^ux^v + X^u Where Lv^u is an antisymmetric Lorentz matrix generated by 6 "charges" in a generalized sense (3 space-space rotations of "Magnetic" ("Vortex") Rotational Momentum 12,13, 23 plus 3 space-time rotations or boosts 01, 02, 03 between 2 Global Inertial Frames (GIF) in uniform non-accelerating motion where neither relative speed nor relative direction changes. We also have the 4 "affine" displacements X^u generated by 4 more "charges", i.e., Energy and Linear Momentum. Physical quantum BIT waves are UNITARY representations of this space-time symmetry group. Let psi(x^u) be part of such a wave group representation valued in the complex numbers. For example look only at the 0 "time coordinate" psi(t) = e^iHt/hbar psi(0) where H is the Hamiltonian generalization of the "Energy" at least for a conservative system. This is the rigid 10 parameter continuous Lie Group of Poincare. There is the deeper 15 parameter Conformal Group. First we have the global SCALE "dilations" D so that x'^u = D(Lv^ux^v + X^u) Then there are 4 more "special conformal translations" between timelike observers and now its a sticky wicket because they correspond to transformations from an instantaneous comoving LIF and a "constantly accelerating" LNIF in the sense of Chapter 6 of MTW "hyperbolic motion" where already a key error of physical interpretation that Hal Puthoff and Michael Ibison make becomes apparent in this simplest toy model like the "hydrogen atom" in atomic physics or the "quantum harmonic oscillator" in 1 dimension in quantum field theory. The 4 Special Conformal Translations seem to require NONLINEAR GROUP REPRESENTATIONS and already display the nonlinearity of General Relativity demanded by the Einstein Equivalence Principle that is analogous to the non-Abelian Yang-Mills Local Gauge Symmetry Principle of compensating gauge force fields that restore the broken rigid symmetry with additional dynamical degrees of freedom introducing DIRECT BACK-ACTION where there was none before. For example, in Special Relativity, Matter-Energy gets its marching orders from Geometry but NOT VICE VERSA i.e. ACTION WITHOUT REACTION! Locally gauging the infinitesimal Pu Lie algebra generators of the Hilbert space unitary representations of the raw spacetime global displacements X^u in the Poincare group transformations x'^u = Lv^ux^v + X^u Gives exactly Einstein's gravity with the compensating gauge field as du(x) whose strain tensor is huv(Curved Space-Time) = (1/2)[du(x),v + dv(x),u] Where Einstein's geometrodynamic field of 1915 is guv(Curved Space-Time) = nuv(Flat Space-Time) + huv(Curved Space-Time) I have gone even deeper showing that du(x) = Lp^2(Goldstone Phase of MACRO-QUANTUM Vacuum Coherence Field),u Lp^2 = hG/c^3 i.e. Gravity emerges out of a micro-quantum flat vacuum "BCS" instability in the spin 1/2 spin 1 quantum fields along with the dark energy/dark matter as randomly fluctuating residual micro-quantum zero point fluctuating "normal fluid" "exotic vacuum: regions of space-time that anti-gravitate and gravitate respectively on different scales and with strengths that in the micro-scale are 10^40 G(Newton). This instability gives inflationary cosmology in the large scale in the sense of "physical wavelets." Note as c - infinity h & G fixed there is no gravity. Similarly as h - 0 G and c fixed there is no gravity etc. This in addition to G - 0 with h & g fixed. Note also c^4/G = String Tension Lp^2 = hG/c^3 = hc(String Tension)^-1 and there is no gravity when Lp^2 - 0 for whatever reason! One reason is infinite string tension with hc finite - no gravity since space-time is too stiff to bend with mass-energy. Clearly what I am doing here is very profound. http://qedcorp.com/APS/EmergentGravity.doc http://qedcorp.com/APS/StarGate1.mov Back to the Special Conformal "Relativistic Rocket" Translations and Puthoff's PV error. Look at 6.17 p. 173 in MTW where in the approximation that space-time region scale L of the LIF obeys L c^2/g ~ 10^18 cm at Earth's surface - no great restriction. The instantly co-moving geodesic LIF observer's coordinate differentials are dx^u where ds^2 = nuv(FLAT)dx^udx^v The LNIF coordinates of the constantly accelerating non-geodesic hyperbolic observer are dx'^u where the same INVARIANT ds^2 is (6.18) ds^2 ~ - (1 + (gx'^1/c^2))^2(dx'^0)^2 - (dx'^1)^2 - (dx'^2)^2 - (dx'^3)^2 gx'^1/c^2 1 is the approximation x^0 = (c^2/g + x'^1)sinh(gx'^0/c^2) x^1 = (c^2/g + x'^1)cos (gx'^0/c^2) x^2 = x'^2 x^3 = x'^3 x^2 - (ct)^2 = c^4/g^2 "hyperbolic world line of the LNIF non-geodesic observer who feels artificial gravity. This coordinatization is such that for a Relativistic Rocket with constant g Distance X rocket goes and time T measured by Earth telescope/radar is X = (c^2/g)cosh[g(Ship Proper Time)/c] cT = (c^2/g)sinh[g(Ship Proper Time)/c] The NONLINEARITY of the 4 Special Conformal Translations is in the hyperbolic cosh and sinh functions of the accelerated observer's proper time of actual aging. * OK Puthoff's basic interpretational error of PV is implicit in MTW's remark about Fig 6.4 p. 173: "At a certain distance from the accelerated world line, successive spacelike hypersurfaces instead of advancing with increasing tau" (Ship's Proper Time), WILL BEGIN RETROGRESSING (CAPS mine). At this distance and at greater distances, the concept of 'coordinates relative to the accelerated observer' become ambiguous and must be abandoned." Basically we have exceeded the domain of validity of the "coordinate patch" we started from because when that weird retrogression starts gL/c^2 ~ 1. The same essential thing happens in Puthoff's PV with K = e^2GM/c^2r. There is a critical r* such that when r r* and r - 0 the SPACELIKE surface area of concentric spheres INCREASES rather than decreases. Indeed, Puthoff, I surmise, uses that argument to explain the scene in Jacques Vallee's "Fastwalker" where the interior of the alien saucer is much bigger in surface area than the outer skin area. Using Puthoff's metric on the micro-geon scale gives entirely the wrong answer that the electron should look bigger and bigger as the scattering momentum transfer increases! This false conclusion is based on Hal's naive "engineering approach" using common sense Euclidean Geometry which is also the same basic error in Yilmaz's "bi-metric" notion that space-time is really flat in 4D at all scales that Puthoff also agrees with. Indeed the need to use an atlas of coordinate patches sewn together is a triumph of Einstein's Equivalence Principle as a "classical approximation" far from a curvature singularity and at a scale Lp^2 = hG/c^3. |

I read your article with great interest, but I must point out an important fact to you that I think you overlooked. The local "space-time" paradigm of Penrose has clearly illustrated the need for a "brane-string theory" approach to resolve the small gc problem as posed by Hawkings and Rosenblatt, which in essence is the argument needed for the BIT unitary waves to converge in the Markov limit of small T3 under hyperinflationary Guth solutions that do not exhibit "bending" near the singular solutions nor those which give zero-field (or as I all them the "trivial "nth" solutions) solutions outside the asymptotic range in which ANY operators of a SO(3) type can produce spurious or multiple solutions on any non-singular manifolds and at the same time claims to satisfy both the relativistic Dirac equations in MV/PUV3 and also any Bianchi branch for the Lie group Poincare representation of the attractors that govern the low order solutions to the basic field equations. This is obviously impossible. Now, Bergann has constructed the PUV / MV diffeomorphisms that map these singularities outside the Schwartzchild radius so that even infinitesimal contractions could produce the singularities needed by the loc Diff(3) tensors in a fixed inertial frame field limit, so that these two facts combined give rise to the "Smale" limit for the diffeomorphic transformations that essentially maps a "brane world" into the string world in which the graviton exchange energy we need in this limit is simply the Fermi resonance exchange energy if we take the kernel of the transformation neeed to be that for the Pauli adjoint identity in a singular spinor field of the type SU(3)xSO(2) (where also, we should point out, non-adjacency prevents Dirac holes produced by the mutual graviton-boson parity rule from nearest level occupancy), thus giving us that the equations for a Fermi sea of strings that will produce such a dilation follow from the transformation of the Fermi energy levels (in a matrix sense) to the continuum limit of the Smale for the "brane equations". The problem of course is that in the Fermi regime of non-local interactions one finds : G( c) = Pi * Exp(c (integral over space time(Goldstone(q)) dq) It is well known that this regime gives rise to the paradoxical "diffusion limit" of Kramers that taken semi-classical leads to a non-equilibrium Baym collapse, but if viewed from a many worlds theory perspective we can get another interpretation of the higher dimensional Klein-Kazlua equations that form the tensor bundle solutions for the ergodic non-stationary Einstein field equations, which involves the introduction of a higher dimensional field theory off the local manifold as imposed by Baldwin and moreover the convergence in the high field frequency of the so-called impedance driven oscillations from brane contacts that produce these shock wave oscillations. Pauli noted that one solution to the non-stationary inertial frame solutions to the left-Eddington solutions at zero field are simply: X(t) = T Diag[Sinx(xt) / Div(x*t)] T* And that the adjoint satisfies: [X*(t)]^c * X(t) = 0 so the local manifold dilates near the zero point singularities. Now as you probably noted by now this is an ENTIRELY NEW way of looking at the Eddington-Penrose SVT equations. Witten has not acknowledged that zero-field spinors do address the adjacency problem nor has he shown how the gc limit value follows naturally from this interpretation. I want to point out that the Lorentz matrix for the "charges" that Witten has previously proposed do not give the result that branes can contact in manifolds that satisfy PUV / MOT conitions. This fact alone must raise eyebrows among committed fans of the GIF Feynman Kac propagators, since renormalization in the sense of Kadanoff gives "brane" attractors of fractional dimensions that exactly agree with the predictions of earlier string theorists. (BTW, Mandelbrot renomalization gives the same result). This indicates that no string theory in a brane embedded manifold will give solutions to the Einstein stationary field equations without ergodic convergence. Hopefully these observations will put some on the right track. MB |
