Varying Constants, Gravitation and Cosmology
Varying constants, Gravitation and Cosmology Jean-Philippe Uzan Institut d’Astrophysique de Paris, UMR-7095 du CNRS, Universit´ePierre et Marie Curie, 98 bis bd Arago, 75014 Paris (France) and Department of Mathematics and Applied Mathematics, Cape Town University, Rondebosch 7701 (South Africa) and National Institute for Theoretical Physics (NITheP), Stellenbosch 7600 (South Africa). email: [email protected] http//www2.iap.fr/users/uzan/ September 29, 2010 Abstract Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to mat- ter. This will induce a violation of the universality of free fall. It is thus of utmost importance for our understanding of gravity and of the domain of validity of general relativity to test for their constancy. We thus detail the relations between the constants, the tests of the local posi- tion invariance and of the universality of free fall. We then review the main experimental and observational constraints that have been obtained from atomic clocks, the Oklo phenomenon, Solar system observations, meteorites dating, quasar absorption spectra, stellar physics, pul- sar timing, the cosmic microwave background and big bang nucleosynthesis. At each step we arXiv:1009.5514v1 [astro-ph.CO] 28 Sep 2010 describe the basics of each system, its dependence with respect to the constants, the known systematic effects and the most recent constraints that have been obtained. We then describe the main theoretical frameworks in which the low-energy constants may actually be varying and we focus on the unification mechanisms and the relations between the variation of differ- ent constants. -
We Begin with a “Trivial” Condition on Massive Gravitons, and Ask Now How This Condition Affects Future Efforts in Early Universe GW Investigations
We begin with a “trivial” condition on massive gravitons, and ask now how this condition affects future efforts in early universe GW investigations. Forefront of research questions investigated with massive gravity, and emergent space-time ANDREW WALCOTT BECKWITH Physics Department, Chongqing University, College of Physics, Chongqing University Huxi Campus, No. 44 Daxuechen Nanlu, Shapinba District, Chongqing 401331, People’s Republic of China [email protected]; [email protected] Abstract The methodology is simple. Use a construction for a minimal time-step, then from there get emergent space-time conditions for a bridge from a nonsingular start to the universe, to potential Quantum gravity conditions. Our Methodology is to construct using a “trivial” solution to massive gravitons, and a nonsingular start for expansion of the universe. Our methodology has many unintended consequences, not the least is a relationship between a small timestep, t, the minimum scale factor and even the tension or property values of the initial space-time wall, and that is a consequence of a “trivial” solution taking into account “massive” gravitons From there we next will in future articles postulate conditions for experimental detectors for subsequent data sets to obtain falsifiable data sets. Minimum scale factor, cosmological constant, space-time bubble, Penrose singularity I. Begin first with a description of the emergent tunneling wave space-time equation used to compare the start of expansion, of that wave equation, with Planckian-era quantum conditions We use the construction from [1] as to, if the initial ‘potential’ V () is very large, how to isolate the form of the wavefunction, especially if aV2 () 1, even if a is the initial value, i.e. -

(Vacuum) Energy and Quantum Field
IOSR Journal of Applied Physics (IOSRJAP) ISSN – 2278-4861 Volume 1, Issue 1 (May-June 2012), PP 08-63 www.iosrjournals.org Of void (vacuum) energy and quantum field : - a abstraction- subtraction model 1DR K N PRASANNA KUMAR, 2PROF B S KIRANAGI AND 3PROF C S BAGEWADI 1Post doctoral researcher, Dr KNP Kumar has three PhD’s, one each in Mathematics, Economics and Political science and a D.Litt. in Political Science, Department of studies in Mathematics, Kuvempu University, Shimoga, Karnataka, India 2UGC Emeritus Professor (Department of studies in Mathematics), Manasagangotri, University of Mysore, Karnataka, India 3Chairman, Department of studies in Mathematics and Computer science, Jnanasahyadri Kuvempu university, Shankarghatta, Shimoga district, Karnataka, India Abstract: A system of quantum field dissipating void and a parallel system of quantum field and void system that contribute to the dissipation of the velocity of void is investigated. It is shown that the time independence of the contributions portrays another system by itself and constitutes the equilibrium solution of the original time independent system. Methodology reinforced with the explanations, we write the governing equations with the nomenclature for the systems in the foregoing. Further papers extensively draw inferences upon such concatenation process, ipsofacto. Significantly consummation and consolidation of this model with that of the Grand Unified Theory is the one that results in the Quantum field giving rise to the basic forces which is purported to have been combined at the high temperatures at the Big Bang Vacuum energy is reported to be the reason for the consummation of the four forces at the scintillatingly high temperature. -
