The Bases of the Unifying Theory of Physics

Authors: Mihai Gheorghe
Comments: 130 pages.

In this book, a new theory is developed which has as a starting point the Planck quantum of mass-space-time and can answer the five big unsolved problems of modern physics: the unification of general relativity with quantum mechanics; deterministic formulation of fundaments of quantum mechanics; the description of different particles and forces in physics using one single theory; the elimination of adjustable variables in physics of elementary ; the nature of the phenomena known as the dark energy.

The Physical Consequences of Using of the Energy-Momentum Transport Wave Function in the Gravitational and Electrostatic Interactions

Authors: Mirosław J. Kubiak
Comments: 5 pages

Contemporary physics does not explain, how the energy and momentum are transported with the particle (body) by means of the elementary quanta of action, when the velocity of the particle has the speed of light or decrease from the relativistic case to the nonrelativistic. We applied simple model of the energy-momentum transport wave function for the elementary quanta of action connected with the gravitational and electrostatic interaction [1] and we have found one equation, which describes unification of the gravitation and electrostatic interactions.

Selected Papers on Low-Energy Quantum Gravity

Authors: Michael A. Ivanov
Comments: 209 pages. The second version of a free ebook of author’s selected papers on low-energy quantum gravity.

A collection of 18 author's papers on low-energy quantum gravity is presented in the second version of a book. These papers were written during 2000 - 2017. In the papers, main results of author's work in a non-geometrical approach to quantum gravity are described, among them: the quantum mechanism of classical gravity giving a possibility to compute the Newton constant; asymptotic freedom at short distances; an interaction of photons with the graviton background leading to the important cosmological consequences; the time delay of photons due to interactions with gravitons; comparisons of cosmological consequences of the model with observations. A quantum mechanism of classical gravity based on an existence of this sea of gravitons is described for the Newtonian limit. This mechanism needs graviton pairing and "an atomic structure" of matter for working it. If the considered quantum mechanism of classical gravity is realized in nature, then an existence of black holes contradicts to the Einstein's equivalence principle: their gravitational and inertial masses differ in the model. It is shown that in this approach the two fundamental constants - Hubble's and Newton's ones - should be connected between themselves. The theoretical values of the constants are computed. In this approach, every massive body would be decelerated due to collisions with gravitons. In this version, a re-calculated value of this deceleration has been found taking into account both forehead and backhead collisions of a body with gravitons. It is also shown by the author that if gravitons are super-strong interacting particles and the low-temperature graviton background exists, the basic present-day cosmological conjecture about the nature of redshifts may be false. In this case, a full magnitude of cosmological redshift would be caused by interactions of photons with gravitons. Non-forehead collisions with gravitons will lead to a very specific additional relaxation of any photonic flux. It gives a possibility of another interpretation of supernovae Ia data - without any kinematics and introduction of dark energy. A few possibilities to verify model's predictions are considered: the specialized ground-based laser experiment; a non-universal character of the Hubble diagram for soft and hard radiations; the linear dependence of the Hubble parameter H(z) on the redshift z; galaxy/quasar number counts.

Higher Dimensional Quantum Gravity Model

Authors: Lukasz Andrzej Glinka
Comments: 30 pages

In this paper the constructive and consistent formulation of quantum gravity as a quantum field theory for the case of higher dimensional ADM space-times, which is based on the author previous works, is presented. The present model contains a certain new contribution which, however, do not change the general idea which leads to extraordinary simple treatment of quantum gravity in terms of fundamental notions of quantum field theory, like e.g. the Fock space, quantum correlations, etc. We discuss the way to establishing the dimension of space and the relation to string theory of the model.

de Sitter Symmetry and Quantum Theory

Authors: Felix M. Lev
Comments: 14 Pages. A revised version published in Physical Review D, Vol. 85, Issue 6, 065003 (2012).

de Sitter symmetry on quantum level implies that operators describing a given system satisfy commutation relations of the de Sitter algebra. This approach gives a new perspective on fundamental notions of quantum theory. We discuss applications of the approach to the cosmological constant problem, gravity, and particle theory.
