A Hypothesis on the Nature of Light

Authors: J. Arnold
Comments: 14 Pages

It is proposed that light is at absolute rest, its apparent motion being the reflection of the motion of mass in time. The hypothesis resolves the paradox of the apparent wave/particle duality of light, accounts for its speed being invariant and a limit, explains numerous other peculiarities of its behavior, and identifies the motion of mass in time as the source of gravitational energy.

Why Trimmer et Al. "Did not Detect" Aether Wind in 1973?

Authors: V.V.Demjanov
Comments: 4 Pages

          In 1960s several authors began independently studies of the interferometric detection of "aether wind" using in the device optical media. Shamir&Fox in 1969 made measurements on the plexiglas and declared them "negative" (whereas they registered the shift of the fringe at ~1/3000 of its width, and "determined" a corresponding to it velocity of aether wind ~6.6 km/s). In 1973 Trimmer et al. mounted at the one-armed device the glass optics and registered with a big resolution the shift of the interference fringe (at most ~10–6 of its width) and determined by it the speed of "aether wind" ~3.8 cm/s. This result enhanced still more the confidence in that the attempts to detect aether are unfavorable. However, my results of the same years being favorable fell out of the common line of "negative" verdicts to aether. I managed to register on gases, liquids and solid optical materials million times greater relative fringe shifts (0.01÷5.0), revealed the horizontal projection of the aether wind velocity hundreds km/s. Since my results "weakened the experimental foundation of special relativity", their publishing is rejected until now.
          In the current report I argue reasonably, relying on my experience, that Trimmer et al. (as well as Shamir &Fox), actually obtained positive results in their measurements of aether wind which amounts to several hundreds km/s, proceeding from the declared by them resolution of their experimental units. I believe their experimental data. But I guess that they were faced with hidden artefacts in the interferometer with solid optic materials and not aware of it. The theory used by them for processing the measurements of the interference fringe shift obtained is not appropriate for interferometers with solid optical materials. I have found the possible reason why Trimmer et al. did not reveal the experimental facts undermining theories repudiating aether.

Gravitation, Force and Geometry

Authors: J. Arnold
Comments: 2 Pages

Gravitation is described as a uniquely geometric phenomenon, incompatible with the concepts of force and energy, and only analogically associable with non-geometric mathematical formalizations. In particular, the mathematical derivation of gravitational waves from the field equations is shown to be arbitrary and physically untenable.

The Theory of Relativity is Wrong

Authors: Emil D. Gigov
Comments: 18 pages

Very true scientists, such as Rutherford, Soddy, Michelson, Sagnac, Lenard, Larmor, McMillan and others, have claimed, that the Theory of relativity is wrong. Even Poincare and Einstein are hinted something similar. Classical physics is far from simple, already during the XIX century has been spoken about things like gravity waves, nuclear power and variable mass. Theory of relativity as a whole, is based only on the hypothesis, that the speed of light in Euclidean empty space is, invariant universal constant. But in reality this velocity is variable, in Newtonian sense. Newton's emission theory of light, has been proven through many experiments, for example by those of Michelson, Sagnac and Fizeau. Also, the velocity of photons in one ray, is variable with respect to lateral observer, and is consistent with the classical law for velocity addition.

Gravitons Writ Large; I.e. Stability, Contributions to Early Arrow of Time, and Also Their Possible Role in re Acceleration of the Universe 1 Billion Years Ago?

Authors: A. Beckwith
Comments: 19 pages, one figure. Ties in DM and DE, in terms of a treatment partly suggested by Yurov, as of 'double inflation'.

This document is due to a question by Debasish of the Saha institute of India asked in the Dark Side of the Universe conference, 2010, in Leon, Mexico, and also is connected with issues as to the initial configuration of the arrow of time brought up in both Rudn 10 , in Rencontres de Blois, and Fundamental frontiers of physics 11 , in Paris, in July 2010. Further reference is made as to how to reconcile early inflation with re acceleration, partly by dimensional analysis and partly due to recounting a suggestion as by Yurov , which the author thinks has merit and which ties into, to a point with using massive gravitons as a re acceleration of the universe a billion years ago enabler, as perhaps a variant of DE.

Configuration of the Arrow of Time, in Initial Start of Inflation?

Authors: Andrew Beckwith
Comments: 2 pages, 1 figure. Actual proceedings submission to the Rencontres De Blois 2010 conference , with an emphasis upon issues brought up earlier, in a less organized fashion un Rudn 10, in Moscow, May 30.

Initial relic entropy growth is presented in the context of a zero valued chemical potential and different formulations of overall energy values, which may be tied into massive gravitons appearing at the onset of inflation This is contrasted with the role of gravitons with non zero rest mass in four dimensions a billion years ago. Questions as to if an interplay between two different regimes for 'heavy' gravity are presented s open research issues.

Gravitons, and the Initial Configuration of Arrow of Time in Inflation?. Part 2, of a Discussion Started at Rudn 10, in Moscow, June 30, 2010

Authors: Andrew Beckwith
Comments: 7 pages, one figure. Significant enhancement of arrow of time issue at the onset of inflation which will be brought up in the DICE meeting , with other topics, in September 13-17, 2010.

This investigation sets forth initial conditions for a start of the arrow of time in cosmology based upon the idea that of having initil degrees of freedom set as gstar ~ 1000 initially , instead of a maximum value of gstar ~ 100 - 120 for the number of degrees of freedom during the electro weak era.

Is Initial Data for Cosmological Arrow of Time Emerging Due to Inflation Start?

Authors: Andrew Beckwith
Comments: 5 pages. One figure. Contribution to the Rudn 10 conference by Andrew Beckwith, in a parallel session in cosmology, May 30, 2010 at Peoples Friendship University, Moscow, Russia as a guest of the Russian Gravitational society.

We ask if setting the vanishing chemical potential limit μ -> 0 with entropy S ∝ T3 [1] for a number of degrees of freedom significantly greater than the standard electroweak value of gstar ~ 100 - 120, do we have a new foundation for the arrow of time in quantum cosmology with inflation?

Covariant Energy-Momentum Conservation in General Relativity with Cosmological Constant

Authors: Philip Gibbs
Comments: 11 pages, this is an updated version of an earlier paper originally archived as arXiv:gr-qc/9701028. The cosmological constant has been added to the analysis, plus other small additions. Submitted to Prespacetime Journal.

A covariant formula for conserved currents of energy, momentum and angular-momentum is derived from a general form of Noether's theorem applied directly to the Einstein-Hilbert action of classical general relativity. Energy conservation in closed and flat big-bang cosmologies including cosmic radiation and dark energy is discussed as special cases. Special care is taken to distinguish between kinematic and dynamic expressions.

Could Gravitons from Prior Universe Survive Quantum Bounce to Reappear in Present Universe

Authors: Andrew Beckwith
Comments: 12 pages, 1 figure. Part of what will be brought up in DICE 2010, as of September 13-17, 2010, in Italy . The other part of the DICE presentation will be finished by the end of next week

We ask the question if an entropy S = E/T with a usual value ascribed of initial entropy S ~ 105 of the onset of inflation can allow an order of magnitude resolution of the question of if there could be a survival of a graviton from a prior to the present universe, using typical Planckian peak temperature values of T ~ 1019 GeV. We obtain the values consistent with up to 1038 gravitons contributing to an energy value of E ~ 1024 GeV if we assume a relic energy contribution based upon each graviton initially exhibiting a frequency spike of 1010 Hz. The value of E ~ 1024 GeV is picked from looking at the aftermath of what happens if there exists a quantum bounce with a peak density value of ρmaximum ~ 2.07 ρPlanck as has been considered recently by P. Malkiewicz and W. Piechocki [15] in the LQG bounce regime radii of the order of magnitude of l ~ 1035 meters. In this paper estimates specifically avoids using S = (E - μN)/T are done, by setting vanishing chemical potential μ = 0 for ultra high temperatures. Finally we compare briefly the obtained results with the ones recently investigated by G. 't Hooft [20] and L.A. Glinka [21, 22].

Doppler Shift Reveals Light Speed Variation

Authors: Stephan J. G. Gift
Comments: 8 pages

Light speed variation relative to a moving observer occurring according to classical velocity composition is demonstrated using Doppler Shift. This directly contradicts the light speed invariance postulate of special relativity and confirms ether drift.

Transition of Expansion Acceleration of the Universe Through Negative Mass

Authors: Hyoyoung Choi
Comments: 5 Pages.

This letter explains that density of positive mass and negative mass is almost uniformly throughout the whole universe, but density of positive mass and negative mass included in a random universe radius R can be different from each other. Like this, positive, zero, negative values of total gravitational potential energy are all possible due to density difference of positive mass and negative mass included in a random universe radius R. This letter is showing possibility in explaining the decelerating expansion and accelerating expansion due to density difference of positive mass and negative mass because negative mass and positive mass conducts different forms of movement depending on the density difference of positive mass and negative mass. As change of total gravitational potential energy sign occurs from UT=0 and total gravitational potential energy oscillates based on 0. This provides valid explanation regarding to the problems of the atness of the universe and fine tuning.

An Interpretation of the Laws of Gravity and Inertia

Authors: Giuliano Bettini
Comments: 16 Pages. v1 in Italian, v2 in English

Ideas on a source of inertia from fixed stars have crossed Physics least Mach onwards. Equations "Maxwell-like" for gravitation and inertia were obtained by several authors as a subspecies of the simplified theory of General Relativity. A precursor was Dennis Sciama. Introducing a four-potential, I submit here a tentative interpretation of our laws about gravity and inertia, in complete analogy with electromagnetism. In classical mechanics is not introduced, usually, a four potential. The field produced by this four-potential describes both gravitational and inertial forces. Admit the gauge transformation on potential is equivalent to enunciate the equivalence principle, and vice versa. Inertial forces (ex. Coriolis force) are interpreted as a field action. All the inertia is interpreted as a field action. The physical presence of this field seems to be a fact, even more concrete the usual admission of inertial "fictitious forces".

One-Way Light Speed Determination Using the Range Measurement Equation of the GPS

Authors: Stephan J. G. Gift
Comments: 8 pages

The one-way speed of light is determined using the range measurement equation of the Global Positioning System. This equation has been rigorously and extensively tested and verified in the Earth-Centred Inertial frame, a frame that moves with the Earth as it revolves around the Sun but does not share its rotation. The result is a simple demonstration of one-way light speed anisotropy depending on the direction of propagation relative to the rotating Earth that contradicts the principle of light speed constancy.

Conformal Gauge Relativity On the Geometrical Unification of Gravitation and Gauge Fields

Authors: Juan Andrés Musante Apolo
Comments: 44 pages

A Lagrangian depending on geometric variables (metric, affine connection, gauge group generators) is given which maintains compatibility with General Relativity. It generates the dynamics for Electromagnetism and other Gauge Fields along with Gravitation, at the time it gives a geometric foundation for the stress-energy tensor of continuous matter. The geometric-invariance principle under this integration is exposed and the resulting field equations are obtained. The theory is developed over the tangent space of a four-dimensional real manifold and the generators become those from the Homogenous Lorentz group.

Lorentz Contraction of Space and the Gravitational Field

Authors: Morgan D. Rosenberg
Comments: 10 pages

By considering the gravitational field as an optical medium with a radially-dependent index of refraction, we are able to show that a physical model of space being radially compressed by mass, rather than curved by mass, as in general relativity, yields the same results predicted by Einstein's theory of general relativity. We are further able to show that this spatial compression is equivalent to the Lorentz contraction of special relativity. The predictions of general relativity are all derived with relatively basic mathematics without reliance on the grossly complex Riemannian geometry needed for Einstein's curved space-time model.

Why Shamir and Fox Did not Detect "Aether Wind" in 1969?

Authors: V.V. Demjanov
Comments: 5 Pages.

Up to 1960ies the measurement of the aether wind velocity by the technology of Michelson presumed that a medium placed across the path of light rays has no substantial significance (except as being an obstacle) for obtaining the expected shift of the interference fringe from the brought together orthogonal rays on the interference of the turnabout device. In 1960ties several authors began independent research on the Michelson-type interferometers with different optical media used as light carriers. J.Shamir and R.Fox declared "negative" the results of their measurements on the plexiglas (though they registered the fringe shift 1/3000 fraction of the fringe's width and determined the respective velocity of aether wind 6.5 km/s). The authors considered this result as "enhancing the experimental basis of special relativity", and their report has been published. My results of same years appeared to be positive. I managed to register on gaseous, liquid and solid optically transparent bodies hundred times greater relative shifts of the fringe (0.01-5.0) giving for horizontal projection of the aether wind velocity the value hundreds km/s. At different times of day and night at the latitude of Obninsk city I registered the changing of this velocity in the interval 140-480 km/s. Insofar as my results "weaken the experimental basis of special relativity", their publication is still refused. I will show in the present report, basing on my experimental experience, that in reality Shamir and Fox obtained positive results. The historical precedence of misunderstanding the positive measurements of aether wind of the order 200-400 km/s, performed by Michelson and Miller in 1920-1930ies at lengthened to 32 m air light carriers, described by me in arXiv:0910.5658v3, 24 June 2010, repeated in the work by Shamir and Fox. Misunderstood was another artifact, manifesting itself in an interferometer with a solid light carrier. In the current work, I explain the nature of this artifact, hiding from Shamir and Fox their experimental success in detecting the aether wind velocity of hundreds km/s. I discussed also the inadequacy of their own interpretation of the results.
