The Sagnac effect (also called Sagnac interference), named after French physicist Georges Sagnac, is a phenomenon encountered in interferometry that is elicited by rotation. The Sagnac effect manifests itself in a setup called a ring interferometer. A beam of light is split and the two beams are made to follow the same path but in opposite directions. To act as a ring the trajectory must enclose an area. On return to the point of entry the two light beams are allowed to exit the ring and undergo interference. The relative phases of the two exiting beams, and thus the position of the interference fringes, are shifted according to the angular velocity of the apparatus. This arrangement is also called a Sagnac interferometer http://en.wikipedia.org/wiki/Sagnac_effect0 = 1 + B.c'/cg00^1/2 + c'^2/c^2define x = |c'/c|Thereforex^2 + Bcos@x/g00^1/2 + 1 = 0<3ca857f705daba6b9e6e6d3ccad7990f.png>2x+,- = (-Bcos@x/2g00^1/2 +,- [B^2cos^2@/g00 - 4]^1/2)Note, the very bizarre behavior at a horizon g00 --> 0, where the constant "4" term is ignorableone root for the physical speed of light converges to zero, but the other diverges to infinity (classical limit) when cos@ =/= 0On Apr 18, 2013, at 7:57 PM, Paul Zielinski <firstname.lastname@example.org> wrote:If the physical speed of light propagating through the vacuum depends on acceleration or rotation of the observer's reference frame, then it follows that in the absence of a light medium, the relativity principle of 1905 SR doesn't generalize to accelerating frames. If the physical speed of light depends on physical acceleration or rotation of the source, then the light principle of 1905 SR doesn't generalize to non-inertial motion.Either way, if you're right, the Sagnac experiment would appear to block generalization of Einstein's two principles as stated in his 1905 relativity paper. Which means that the ability to generalize application of these two principles does not discriminate between the Einstein and Poincare versions of "special" relativity.The difference between Poincaré and Einstein with regard to the ether was not a dispute about whether redundant elements should be eliminated from physical theories; it was a dispute about whether a light medium was truly redundant. Poincaré, the conventionalist, stated quite clearly well before 1905 that once it was determined that the "hypothesis" of an ether was no longer useful to physics, it should be abandoned. His position in 1905 however was that it was still theoretically useful, and not "superfluous" as Einstein argued.The existence of a light medium in the context of the wave theory of light not only ensures automatic satisfaction of the relativity principle, but also *explains* why the speed of light is independent of the speed of the source. For Einstein this was simply a postulate, assumed as a premise with no physical justification. This alone suggests that Poincaré was right not to regard the idea of a light medium as "superfluous".Also, the Poincaré-Lorentz ether was not a material ether. The only essential properties attributed to it were (1) it serves as a physical medium for light propagation; and (2) it defines a preferred inertial frame wrt which inertial clock retardation is an objective physical phenomenon, as opposed to being an observer-dependent kinematical artifact according to Einstein 1905.Point (1) alone shows that notwithstanding Einstein's clever "Machian" 1905 argument for the relativity of simultaneity, Poincaré's ether was not at all "superfluous" once the comparative explanatory powers of the theories are taken into account.Thus it is no mystery as to why Einstein later changed his position on the ether to the point where it became almost indistinguishablefrom Poincaré's, once he had discarded his Machian blinders.I think it's interesting that Smolin, who wrote a book titled "The Trouble With Physics", is to all appearances unaware of this reality.On 4/18/2013 5:39 AM, Jackpacbell wrote:The physical speed of light depends on g0idx^i/cg00dt

Only the coordinate speed depends on frame acceleration. For example, the Rindler horizon is a coordinate singularity, not a geometric inflection boundary. It is a coordinate artifact in globally flat Minkowski spacetime.
Wrong - the Rindler horizon is physical for the LNIF Rindler observer, who sees Hawking black body radiation from it. Of course it's not there for the coincident LIF geodesic observer. Basically this is group theory The field equations must be covariant under different groups & for SO1,3 c is invariant in vacuumThe GR field equations and the spacetime metric are generally covariant. Which means the objective physics does not depend on the choice of coordinates. Neither does it depend on the choice of Galilean vs. Lorentzian coordinate frame transformations.In GR the objective physics is determined entirely by the locally Lorentzian property of the metric.Isn't that obvious?It's more complicated for propagation of light in media c/n Of course interacting fields matter + light is Lorentz covariant but not if you integrate out matter This breaks Lorentz symmetry in the partial description of light aloneYou are not making the necessary distinctions between geometric Lorentz symmetry and Lorentzian coordinate invariance.The physics is determined by the Lorentzian property of the metric, not by coordinate invariance. This should be obvious given the general covariance of the theory.See landau & lifshitz electrodynamics of continuous media.e.g., in a Bose Einstein condensate u can make c/n -> 0But this is all premised on Einstein kinematics. I'm talking about a very different model with Galilean kinematics, and objective clock retardation accounted for by the locally Lorentzian character of the metric. That this works is guaranteed by the generalcovariance of the theory and the tensor character of the Riemann metric.

I'm curious, Paul, if you have a list of attempts to generalize Lorentzian or Poincarean relativity? I know only of Reg Cahill's process physics as a generalization of Lorentzian relativity (neo-Lorentzian), but I'm sure there are others.

The postulates and their consequences are then checked experimentally and, so far, they hold remarkably well."Smolin clearly states that the the Lorentz coordinate frame transformations and thus the relativity of simultaneity of 1905 Einstein SR are a logical consequence of Einstein's two postulates, the light principle and the inertial relativity principle. He also indicates that the relativity of simultaneity is somehow confirmed by empirical observations.These are both red herrings.The light principle is a natural feature of any wave theory of light propagating in a physical medium. It is Einstein who had to pull the light principle out of thin air as a postulate, not the ether theorists. In contrast, the light principle has no natural explanation in Einstein's 1905 version of "special" relativity.The relativity principle is automatically satisfied by any wave theory of light propagating through a medium, since the speed of propagation relative to the medium is automatically invariant under changes in any observer's frame of reference, whether inertial or non-inertial. And even if the state of inertial motion of the medium itself changes, this will not affect the speed of propagation of light with respect to the medium.Finally, a theory of relativity such as Poincare's, which assumes a preferred inertial frame and absolute kinematical simultaneity, can also be formulated in a Minkowski spacetime with Lorentzian metric using Galilean coordinate frames, and yields exactly the same empirical predictions as Einstein's 1905 theory.So from my POV Smolin, while he is quite critical of the current state of theoretical physics, doesn't go nearly far enough.On 4/17/2013 11:46 AM, Paul Zielinski wrote:I found Smolin's responses on SR and the invariance of the speed of light to be somewhat disappointing.

a medium (since the pertinent laws are formulated with reference to the speed of propagation wrt the medium). Not
only that, but the light principle (1) is a natural feature of that model, whereas in Einstein's theory it comes out of
nowhere and is simply presented as a postulate.
In other words, one has to *assume* that there is no light medium in order for (1) and (2) to present a problem to
begin with. Einstein tacitly assumes that there is no light medium, resolves the resulting apparent inconsistency of (1)
and (2) by abandoning objective kinematical simultaneity in favor of Lorentzian kinematical transformations, and then
declares that there is thus *no need* for any reference to a light medium in his theory (which is correct).Of course an unreconstructed Machian would immediately conclude based on this "redundancy" that the hypothesis of

Bohm's theory may seem to provide a handy way to solve the measurement problem, however it encounters some serious challenges at the relativistic level. It has also been argued by Harvey Brown and David Wallace (2005) that even at the nonrelativistic level there are problems with the idea that a Bohmian corpuscle can give you a measurement result (ref. on request).please send referenceOn the other hand TI (extended in terms of PTI) finds its strongest expression at the relativistic level, in that one has to take absorption into account in the relativistic domain in any case, and absorption is the key overlooked aspect according to TI. In fact I argue that the measurement problem remains unsolved in the competing 'mainstream' nonrelativistic interpretations because they neglect the creation and annihilation of quanta. Emission is action by creation operators, and absorption is action by annihilation operators. You can get a definitive end to the measurement process by taking absorption (aka annihilation) into account. This happens way before the macroscopic level (see http://arxiv.org/abs/1204.5227, section 5) so that you don't get the usual infinite regress of entanglement of macroscopic objects which is the measurement problem.RKI agree about the importance of including both creation and destruction in a time loop, but I don't see off-hand that is a problem for Bohm's theory.Indeed, in my debate with Jim Woodward on dark energy density hc/Lp^2A as redshifted advanced Wheeler-Feynman Hawking radiation from our detector dependent future de Sitter horizon where the Hawking radiation density is hc/Lp^4 - the TI loop in time means that we must use the static LNIF representation of the metric for the virtual electron-positron pairs stuck at r = A^1/2 - Lp relative to the detector at r = 0 wheregtt = 1 - r^2/Agiving 1 + zstaticLNIF ~ (A^1/2/Lp)^1/2 = femit/fdetectnot the usual FRW metric where gtt = 1 and there is no horizon - that works for co-moving absorbers that will see the effect of expanding space for retarded radiation from us & 1 + zcomovingLIF = anow/athenThe static LNIF redshift factor for advanced radiation source frequency c/Lp from the future horizon back to our past detector is ~ (Lp/A^1/2)^1/2.Even for retarded black body radiation reaching us from a past black hole horizon with Hawking's original redshifted peak frequency c/A^1/2, there should be a second peak signal at c/(LpA^1/2)^1/2 from radial oscillations of the horizon. Hawking's signal is from surface mode vibrations of the horizon.

I attended the above session at General Atomics June 2008.4 The gravitational dynamical Casimir effect, and the generationof coherent gravitational radiationIn this final section, we speculate that the above ideas can be extended to include the case of gravitationalradiation. The physical concept that ties all these ideas together is the crucial use of the DeWitt minimalcoupling rule in all of them.In particular, we briefly comment on the possibility of extending the “separated parametric oscillator”idea for generating EM microwaves by means of the vibrating SC membrane placed inside the extremelyhigh Q “triple” SC cavity, as depicted in Figure 4, to the much more speculative idea of generating GRmicrowaves using the same vibrating SC membrane inside the same “triple” SC cavity. This extensionis based on the fact that the interaction Hamiltonian Hhh in (39) is mathematically identical to thatof the interaction Hamiltonian HAA in (38). Furthermore, we are assuming that it is permissible forgravitational radiation fields to be second quantized (see (42)).However, for this extension of the parametric oscillator idea to work, it is crucial that the wallsSC cavity, including the surfaces of the moving SC membrane, reflect GR microwaves with as high areflectivity as in the case of EM microwaves. In the paper “Do mirrors for gravitational waves exist?”, it was predicted that even thin SC films are highly reflective mirrors for GR plane waves. Thissurprising prediction was based on the DeWitt minimal coupling rule (20) applied to the Ginzburg-Landau theory of superconductivity. The “off-diagonal long-range order” (ODLRO)  nature of theCooper pairs causes these pairs to behave differently from the ions in the ionic lattice, for which ODLROdoes not exist. As a result, inside the SC thin film, the Cooper pairs, which exhibit constructive ABinterference, do not undergo geodesic motion, in contrast to the ions, which do undergo geodesic motion,in response to incident GR radiation. This difference in the internal motions of the Cooper pairs and ofthe ions inside the SC in the presence of GR radiation, leads to a charge separation effect induced by anincoming GR plane wave, such that a huge back-action of the SC film on the GR wave that causes itsreflection, results.If such SC mirrors for GR waves were indeed to exist in Nature, then moving SC mirrors would notonly be able to do work like a piston on these waves, but would also simultaneously lead to a Dopplereffect that leads to the exponential amplification of these waves above the threshold for parametric oscillation,as explained above. Thus, a laser-like generation of coherent GR waves starting from vacuumfluctuations should become possible. If so, a Hertz-like experiment for GR radiation at microwave frequencies would become feasible to perform.On Apr 1, 2013, at 3:46 PM, JACK SARFATTI <firstname.lastname@example.org> wrote:ThanksI am always interested in what Ray Chiao is doing.On Apr 1, 2013, at 3:01 PM, Gary S Bekkum <email@example.com> wrote:A thought experiment is proposed to demonstrate the existence of a gravitational, vector Aharonov-Bohm effect. A connection is made between the gravitational, vector Aharonov-Bohm effect and the principle of local gauge invariance for nonrelativistic quantum matter interacting with weak gravitational fields. The compensating vector fields that are necessitated by this local gauge principle are shown to be incorporated by the DeWitt minimal coupling rule. The nonrelativistic Hamiltonian for weak, time-independent fields interacting with quantum matter is then extended to time-dependent fields, and applied to problem of the interaction of radiation with macroscopically coherent quantum systems, including the problem of gravitational radiation interacting with superconductors. But first we examine the interaction of EM radiation with superconductors in a parametric oscillator consisting of a superconducting wire placed at the center of a high Q superconducting cavity driven by pump microwaves. We find that the threshold for parametric oscillation for EM microwave generation is much lower for the separated configuration than the unseparated one, which then leads to an observable dynamical Casimir effect. We speculate that a separated parametric oscillator for generating coherent GR microwaves could also be built.http://arxiv.org/pdf/1301.4270v3--
