T10.00001: A proposed model for ordinary gravitation David Stallard A model is proposed for ordinary gravitation, i.e. far from a black hole, to conform to Newton's law. Weinberg wrote: ``the exchange of these gravitons (zero mass, spin two) will produce just the gravitational effects that are predicted by general relativity.'' Leo Blitz showed that dark matter in the galaxy has gravitational effects on visible matter. Postulate: An isolated, spherical mass m in nearly-zero-gravity space is presumed to radiate gravitons isotropically and to receive an isotropic flow-rate of gravitons of equal power from dark matter. Example 1: An isolated hydrogen atom m receives gravitons and rises in gravitational energy to a level such that the next incoming graviton causes the discharge of three gravitons in the same vector direction, one having helicity opposite to that of the incoming graviton. If the latter is from visible matter, gravitational attraction results. Energy, linear momentum and spin are conserved. Example 2: m is a small spherical mass. If a spherical mass M is introduced nearby, its radiation causes a reduction in the flow-rate of gravitons received in the vicinity of M from m, and an increase in the oppositely-directed gravitons from m, which then experiences a momentum force attracting it to M.

T10.00002: Empirical Evidence Suggest A Need For A Different Gravitational Theory Benjamin Solomon This paper presents some recent finding in alternative gravitational hypotheses. Using gamma-ray burst Nemiroff [2012] showed that quantum foam could not exists. Solomon [2011] showed that gravitational acceleration is not associated gravitating mass, and equivalent to not knowing the photon source properties to know its frequency. Solomon [2011] showed that gravitational acceleration g is determined by $\tau $ the change in time dilation over a specific height multiplied by c$^{2}$ or g$=\tau $c$^{2}$. Force is expressed as a Non Inertia (Ni) Field and not by the exchange of virtual particles as is required by quantum {\&} string theories. This paper examines 11 inconsistencies in physical theories that manifest from empirical data, to provide insights on how physical theories need to change to eliminate these inconsistencies. Exotic matter, expanding strings, a moving wave function and even a fixed spacetime continuum generate inconsistencies in physics. Further, our physical theories do not explain how particle probabilities are implemented in Nature. This paper concludes by proposing alternative axioms for spacetime and structuring particles that would be consistent with the Special Theory of Relativity. [Preview Abstract] |

T10.00003: Unify the electromagnetic force and gravitation Sheng Ming Zheng In the process of mankind investigate natural rule: people know four kinds of force: electromagnetic force, gravitation, weak force, and strong force. Meanwhile people use these four kinds force to explain all phenomena in the Nature. Obviously people do not know their mechanism of origin until now. On the other hand, these four kinds force is the difference showing form of one force, is not it? For solve these questions and find their mechanism of origin, I do some experiments and discover that the moving photons produce gravitation. This discovery shows the origin of gravitation. Meanwhile I also do experiments show that light is a particle, but is not a wave-particle duality. My experiments show that the elementary particles moving produce gravitation and electromagnetic force, this effect also produce wave effect. That is to say my experiment and calculate not only reveal the origin of gravitation, but also reveal the origin of electric charge and magnetic force. Base on this I first unify the electromagnetic force and gravitation.

T10.00004: Unifying Physics Shantilal Goradia Century old GR fails to unify quantum physics, nuclear force or distinguish between the mass of living bodies from inert mass. Probabilistic gravity [1] explains strong coupling (nuclear force). The natural log of the age of the universe, 10E60 in Planck times, equaling 137 (1/Alpha) extends physics to deeper science, if we stand on the shoulders of giants like Feynman and Gamow. Implications of [1] are that it is not the earth, but M and S numbers of the particles of the earth are remotely interacting with corresponding numbers of the particles of the moon and the sun respectively, neglecting other heavenly bodies in this short draft. This new physics is likely to enable creative scientific minds to throw light on a theoretical basis for an otherwise arbitrary cosmological constant, uniformity of microwave background, further vindication of Boltzmann, quantum informatics, Einstein's later publicized views and more, eliminating the need to spend money for implicitly nonexistent quantum gravity and graviton.\\[4pt] [1] Journal of Physical Science and Applications 2 (7) (2012) 265-268.

T10.00005: Modeling gravitons as either classical or quantum mechanical, using experimental Alicki Van Ryn experimental realization Andrew Beckwith This document uses the Alicki Van Ryn experimental procedure used intially for photons which are spin 1/2 for spin 2 gravitons as a thought experiment to verify/ predict if gravitons and gravitational waves would have either classical or quantum properties. While the experiment is undoable with TODAYS technology, the thought experiment generalizes to spin 2 particles techniques which in principle could lead to determining if gravity is classical or quantum mechanical in nature. The talk is based upon an accepted for publication article (Open journal of Micro Physics) and is an attempt for probing if either loop quantum gravity and/or string theory techniques are appropriate for the origins and genesis of gravitational radiation. If gravity is primarily classical in its foundations, the effect this finding would have on early universe cosmology models would be profound and fundamental. [Preview Abstract] |

T10.00006: Gravity increased by lunar surface temperature James Keene Quantitatively large effects of lunar surface temperature on apparent gravitational force measured by lunar laser ranging (LLR) and lunar perigee may challenge widely accepted theories of gravity. LLR data grouped by days from full moon shows the moon is about 5 percent closer to earth at full moon compared to 8 days before or after full moon. In a second, related result, moon perigees were least distant in days closer to full moon. Moon phase was used as proxy independent variable for lunar surface temperature. The results support the prediction by binary mechanics that gravitational force increases with object surface temperature. [Preview Abstract] |

T10.00007: Gravitational Deflection of Light and Radio Waves Exhibit Impact Parameter Dependency from Solar Plama Limb to Plasma-Free Space above Edward Dowdye Findings consistently show that the observed gravitational light bending is severely impact parameter dependent for both microwaves and the rays of starlight at the plasma limb of the sun. Since the thin plasma atmosphere of the sun has a thickness of a fraction of the solar radius, the gravitational light bending effect as predicted by the light bending rule of General Relativity should be easily detectable above plasma limb in the plasma-free space for at least several solar radii with current technical means. Application of Mathematical Physics fundamentals clearly show that both microwaves and rays of starlight take a minimum-energy or a least-time path in the plasma limb exposed to the gravitational gradient field of the sun. This result is found to be independent of the frequency of the deflected wave. The results is experimentally confirmed by a host of researchers who used a very-long-baseline-interferometer (VLBI) measurement on extra galactic pulsar radio sources to observe the gravitational deflection of microwaves obtaining exactly the results of 1.75 arcsec. The light bending rule of General Relativity suggests that gravitational light bending effects should occur in a plasma-free space as well as in the empty plasma-free vacuum space far above the limb of the sun.
