Gravitoelectromagnetism (Gem), Lagrange Equations and Faraday Induction Law

Authors: Giuliano Bettini
Comments: 18 pages. In Italian, a short English version is included.

Recently gravitoelectromagnetism ("GEM") has been discussed by a number of authors. In this paper, after a brief reminder of viXra:1008.0042 "An interpretation of the laws of gravity and inertia", it is shown that the law of motion and the gravitoelectromagnetic fields can be deduced from the Lagrange function of a non relativistic particle in a non inertial reference frame. The discussion has been extended to the Faraday induction law: a gravity field can be induced in a loop if the gravitomagnetic flux through the loop is changed.

Formal Proof that c is the Limiting Speed

Authors: John Michael Williams
Comments: 6 pages

If light is made of particles or waves which propagate at the same speed in all inertial frames, then the speed of light is the greatest speed possible.

Comment on Arxiv:1009.2266v2, "On the Fine Structure Constant in the Machian Universe"

Authors: Willard Mittelman
Comments: 5 pages

We consider a recent attempt by Gogberashvili and Kanatchikov to connect the value of the fine structure constant α with cosmological parameters. After pointing out an error in the authors' account, we show that by modifying their treatment of dark energy a suitable value of a can still be obtained using current values of the relevant cosmological parameters. We also address the question of α's determination in earlier cosmological eras

Why Over 30 Years Aether Wind Was not Detected in Michelson-Type Experiments with Resonators

Authors: V.V. Demjanov
Comments: 10 pages.

We show that measured by S.Herrmann et al., Phys.Rev.D 80, 105011 (2009) small (but finite) value of relative variation (δν/ν>0) of the resonance frequency of an evacuated optical resonator, when changing its orientation in space, can not serve as an indication of the absence of a preferred direction concerned with the absolute motion of the setup. On the contrary, the finiteness δν/ν>0 testifies to spatial anisotropy of the velocity of light. In order to detect the absolute motion and determine the value and direction of its velocity, the volume of the resonator should be regarded, at any degree of evacuation, as being an optical medium, with its refractive index n>1 to be necessarily taken into account, irrespective of the extent to be the medium's tenuity. In this event the residual pressure of the evacuated medium should be controlled: that will ensure the magnitude of n to be known at least to the first significant digit after 1.00000...
If the working body is a gas then, as in the case of the fringe shift in the interferometer, the shift δν of the resonance frequency of the volume resonator is proportional to n2–1=Δε and to the square of the velocity υ of absolute motion of the resonator. At sufficiently large values of optical density, δν is proportional to (n2–1)(2–n2)=Δε(1–Δε), and at n>1.5 it may possess such a great value that there even becomes possible a jump of the automatic laser frequency trimmer from the chosen m-mode of the reference resonator to its adjacent m±1 modes. Taking into account the effect of the medium permittivity by introducing in calculation the actual value n>1 in experiments with resonators performed by the scheme of the Michelson experiment enabled us to estimate the absolute speed of the Earth as several hundreds kilometers per second.

On Conformal Infinity and Compactifications of the Minkowski Space

Authors: Arkadiusz Jadczyk
Comments: 38 pages

Using the standard Cayley transform and elementary tools it is reiterated that the conformal compactification of the Minkowski space involves not only the "cone at infinity" but also the 2-sphere that is at the base of this cone. We represent this 2-sphere by two additionally marked points on the Penrose diagram for the compactified Minkowski space. Lacks and omissions in the existing literature are described, Penrose diagrams are derived for both, simple compactification and its double covering space, which is discussed in some detail using both the U(2) approach and the exterior and Clifford algebra methods. Using the Hodge ☆ operator twistors (i.e. vectors of the pseudo-Hermitian space H2;2) are realized as spinors (i.e., vectors of a faithful irreducible representation of the even Clifford algebra) for the conformal group SO(4,2)/Z2. Killing vector fields corresponding to the left action of U(2) on itself are explicitly calculated. Isotropic cones and corresponding projective quadrics in Hp;q are also discussed. Applications to flat conformal structures, including the normal Cartan connection and conformal development has been discussed in some detail.

How to Use the Cosmological Schwinger Principle to Predict Energy Flux, Entropy, and an Effective Electric Field at the Start of Inflation in Terms of Inflaton Potentials.

Authors: Andrew Beckwith
Comments: 9 pages, 2 figures. Will be brought up as part of poster in DICE 2010, as part of Beckwith's DICE 2010 contribution to the conference proceedings.

The idea is to cut down on the number of independent variables to get as simple an emergent space time structure of entropy and its generation as possible. Initial assumptions as to TPlanck ~ 1019. An effective electric field, based upon the Cosmological Schwinger principle is derived, via dimensional analysis, then a heat flux, with subsequent entropy production in a manner tied in with candidates as to inflaton potentials in a way the author has not seen in the literature. The effective electric field is important because it enables a direct analogy with the Schwinger result, 1951, of an E field leading to a numerical count of pairs of e+e- echarges nucleated in a space time volume V.t . Note that in most inflationary models, the usual assumption is for a magnetic field, not electric field. Having an electric field permits a kink anti kink construction in lieu of what Beckwith did in CDW (PhD dissertation) plus allows for explicit emergent relic particle frequency range between one to 100 GigaHertz. The novel contribution is the importance of a relic E field, instead of a B field, in inflationary relic particle formation and vacuum nucleation for reasons explained in this manuscript.
