Introduction n Can gravity theory explain galaxy dynamics and cosmology without dominant dark matter? n We need a gravity theory that generalizes GR. Such a generalization is nonsymmetric gravitational theory (NGT). n A simpler theory is metric-skew-tensor gravity (MSTG). n There is also the problem of the nature of Dark Energy that explains the accelerating Universe. n The gravity theory must be stable and contain GR in a consistent way. It must yield agreement with solar system tests and the binary pulsar PSR 1913+16. n The cosmology without dominant dark matter must agree with the latest WMAP and CMB data. 1/13/2005 Miami 2004 3 2. Gravity theory n A popular phenomenological model that replaces dark matter is MOND (Milgrom, Beckenstein, Sanders-McGough). This phenomenology fits the flat rotation curves of galaxies, but has no acceptable relativistic gravity theory (see, however, Beckenstein 2004). n The MSTG theory can explain flat rotation curves of galaxies and cosmology without dominant dark matter. n We need to incorporate quantum gravity in a renormalization group (RG) flow framework with effective running coupling “constants” and an effective action. -
Einstein Not Yet Displaced Controversial Theory of Varying Speed of Light Still Lacks a Solid Foundation
books and arts Einstein not yet displaced Controversial theory of varying speed of light still lacks a solid foundation. Faster Than the Speed of Light: The Story of a Scientific Speculation MILES COLE by João Magueijo William Heinemann/Perseus: 2003. 320 pp. £16.99/$26 George Ellis João Magueijo is one of many who hope to see the epitaph ‘Einstein was wrong, I was right’ on their gravestone. He is a cosmolo- gist who, one rainy morning in Cambridge, suddenly saw the possibility of a varying speed of light (VSL) as an alternative to the inflationary-theory paradigm that domi- nates present-day theoretical cosmology. He knew from the start that it represented a fundamental challenge to physics ortho- doxy (it violates the foundations of Einstein’s special theory of relativity) and would not easily be accepted, but he worked enthusi- astically to develop the idea. He found a collaborator who wavered but eventually completed a joint paper with him on the topic. This was rejected by major journals but was eventually accepted for publication read and referred to. Why, then, his major dis- Magueijo has not gone back to the founda- after a long battle. He then discovered that content? He has had no more difficulty than tions and sorted them out.

Explaining Planet Formation and the Initial Mass Function of Stars with a Universe Composed of Mathematics Plus Re- Evaluation of the Mass-Gravity Relationship
EXPLAINING PLANET FORMATION AND THE INITIAL MASS FUNCTION OF STARS WITH A UNIVERSE COMPOSED OF MATHEMATICS PLUS RE- EVALUATION OF THE MASS-GRAVITY RELATIONSHIP By Rodney Bartlett (corresponding author), [email protected], vUniversity3A (Science and Technology), Stanthorpe, Qld. 4380, Australia Abstract - This preprint is a never-print. It can never be printed in a science journal because that approach has often been tried, only to see the submission's ideas repeatedly rejected as too speculative and non-mathematical. Professor John Wheeler used to say the early papers on quantum mechanics were regarded as highly speculative. Nevertheless, editors of the 1920s published them (today's editors would be too timid). Maybe the maths in it doesn't qualify as maths since it isn't complicated (Einstein used to say a theory that can't be explained to a 6-year-old isn't really understood by its author). Or maybe editors believe the only real maths is the squiggly lines of algebra. The distribution of stellar masses at the birth of stars is called the Initial Mass Function or IMF. Why does the IMF favour the production of low-mass stars? There is a clue in the report that most planetary systems seem to outweigh the protoplanetary disks (PPDs) in which they formed, leaving astronomers to re-evaluate planet-formation theories. (AstroNews 2019) Science must always be free to question everything: even the long- established idea that mass is the cause of gravity (by, according to General Relativity (Einstein 1915), warping and curving space-time). Exploration of the reverse, that gravity forms mass, sounds absurd to modern science. -
1. Introduction
Beichler (1) Preliminary paper for Vigier IX Conference June 2014 MODERN FYSICS PHALLACIES: THE BEST WAY NOT TO UNIFY PHYSICS JAMES E. BEICHLER Research Institute for Paraphysics, Retired P.O. Box 624, Belpre, Ohio 45714 USA [email protected] Too many physicists believe the ‘phallacy’ that the quantum is more fundamental than relativity without any valid supporting evidence, so the earliest attempts to unify physics based on the continuity of relativity have been all but abandoned. This belief is probably due to the wealth of pro-quantum propaganda and general ‘phallacies in fysics’ that were spread during the second quarter of the twentieth century, although serious ‘phallacies’ exist throughout physics on both sides of the debate. Yet both approaches are basically flawed because both relativity and the quantum theory are incomplete and grossly misunderstood as they now stand. Had either side of the quantum versus relativity controversy sought common ground between the two worldviews, total unification would have been accomplished long ago. The point is, literally, that the discrete quantum, continuous relativity, basic physical geometry, theoretical mathematics and classical physics all share one common characteristic that has never been fully explored or explained – a paradoxical duality between a dimensionless point (discrete) and an extended length (continuity) in any dimension – and if the problem of unification is approached from an understanding of how this paradox relates to each paradigm, all of physics and indeed all of science could be unified under a single new theoretical paradigm.

The Status and Prospects of Quantum Non-local Field Theory N. J. Cornish Department of Physics University of Toronto Toronto, Ontario M5S 1A7, Canada & School of Physics University of Melbourne Parkville, Victoria 3052, Australia UTPT-lt-15 1 Abstract It is argued that non-locality is an essential ingredient in Relativistic Quantum Field Theory in order to have a finite theory without recourse to renormalisation and the problems that come with it. A critical review of the physical constraints on the form the non-locality can take is presented. The conclusion of this review is that non- locality must be restricted to interactions with the vacuum sea of virtual particles. A successful formulation of such a theory, QNFT, is applied to scalar electrodynamics and serves to illustrate how gauge invariance and manifest finiteness can be achieved. The importance of the infinite dimensional symmetry groups that occur in QNFT are discussed as an alternative to supersymmetry, the ability to generate masses by breaking the non-local symmetry with a non-invariant functional measure is given a critical assessment. To demonstrate some of the many novel applications QNFT may make possible three disparate examples are mooted, the existence of electroweak monopoles, an mechanism for CP violation and the formulation of a finite perturbative theory of Quantum Gravity. 2 1 Introduction There was once a time, not so very long ago, when a manifestly finite, unitary and gauge invariant Quantum field theory would have been accepted as the natural union of Relativity and Quantum mechanics. Unfortunately, the Quantum field theory born of that time gave infinite results for what should have been small Quantum correc tions. -

Inhomogeneous Cosmology, Inflation and Late-Time Accelerating Universe
Inhomogeneous Cosmology, Inflation and Late-Time Accelerating Universe J. W. Moffat The Perimeter Institute for Theoretical Physics, Waterloo, Ontario, N2L 2Y5, Canada and Department of Physics, University of Waterloo, Waterloo, Ontario N2L 3G1, Canada Abstract An exact inhomogeneous solution of Einstein’s field equations is shown to be able to inflate in a non-uniform way in the early universe and explain anomalies in the WMAP power spectrum data. It is also possible for the model to explain the accelerated expansion of the universe by late-time inho- mogeneous structure. e-mail: john.moff[email protected] 1 Introduction In the following, we shall investigate an exact inhomogeneous cosmological solu- tion of Einstein’s field equations obtained by Szekeres [1], for an irrotational dust dominated universe and subsequently generalized by Szafron [2] and Szafron and Wainright [3, 4] to the case when the pressure p is non–zero. The cosmological model contains the Friedmann-Lemaˆıtre-Robertson-Walker (FLRW) cosmology and arXiv:astro-ph/0606124v2 30 May 2007 the spherically symmetric Lemaˆıtre-Tolman-Bondi (LTB) model [5, 6, 7] as special solutions. The Szafron model describes a more general inhomogeneous spacetime with no prescribed initial symmetry [8]. We will show that the Szafron inhomogeneous cosmology in the early universe near the Planck time can lead to an inhomogeneous inflationary period, which can predict that the primordial power spectrum is not uniform across the sky. Recent investigations have revealed that there appears to be a lack of power in the CMB power spectrum above 600 and anisotropy in hot and cold spots on the sky [9, 10, 11, 12, 13]. -

The Subtleties of Light Alan Van Vliet
The Subtleties of Light Alan Van Vliet P.O. Box 1676, Pinehurst, NC 28370 [email protected] 910.673.6797 910.690.2333 Fax 910.673.8980 Abstract The foundations of modern physics are based upon a conditional constant, a paradox within itself. The “constancy” of the speed of light is valid only when considered in the context of a vacuum or empty space. I propose there is no “caveat” and consequently the speed of balanced, white light is absolute, always 300,000 km/sec. I further propose that the seven monochromatic components of light have absolute, but individual speeds, these speeds differing from the absolute speed of balanced, white light. Based upon these premises, I explore a different explanation for the geometrical “deflection” of light proposed by General Relativity. I consider the gravitational field as a refractive medium that optically disperses light. A viable solution for the “deflection” of light is considered as a result of the curved path created by these “divergent speeds of monochromatic light.” The consideration of this divergent relationship within the very nature of light raises significant questions about the curvature of space-time itself. As a result, this opens the field to the possibility of a non-geometric theory of gravity, one that may more closely align with the quantum theory. In conclusion, I examine the historical implications of Einstein’s quest, his never-ending search for the unification of electromagnetism and gravity, and his personal vision of unity that still guides us today.
