Negative Gravitational Mass: An Ideal Solution for Cosmology

Stéphane Le Corre
This article provides a physical solution to cosmic inflation, the onset of the radiation epoch and the reheating epoch. It does not require dark energy thanks to a zero cosmological constant. Cosmological inflation is a mathematical solution considered necessary for the coherence of cosmological models. There are several versions of it, but there is currently no physical basis to explain it. We show that the existence of negative heavy masses (but always posit

Fabrication and Optical Characterization of Polyvinylidene Fluoride/Neodymium Oxide Nanocomposite Films

Ashok Batra, Adina Showe, James Sampson, Aschalew Kassu, Michael Curley, Kuzhivelil Arun
Polyvinylidene fluoride (PVDF) is employed in a wide range of devices based on its excellent mechanical, optical, high thermal, piezoelectric, pyroelectric, and ferroelectric characteristics. In the current investigation, the pristine and neodymium oxide (Nd2O3) nanoparticles embedded polyvinylidene fluoride (PVDF) thick films were prepared via solution casting method. The Nd2O3 nanoparticles were synthesized via hydrothermal tech

On the Implication of Tai Chi Diagram and Its Value in Physics

Zixuan Wang, Yanbing Zhang, Chengjun Wu
As a symbol of Chinese Yin-Yang theory, the implication of Tai Chi diagram has been widely acknowledged in Natural Sciences and Philosophy in both east and west. Taking three well-known principles in physics for example, “the principle of complementarity”, “dissipative structure theory” and “Wheeler’s principle of austerity”, this paper interprets the symbolic rep-resentation of Tai Chi diagra

Interacting Holographic Dark Energy in Bianchi Type-V Universe with Variable Deceleration Parameter

Vijay G. Mete, Vaibhav D. Bokey, Vasant S. Bawane
The present study deals with spatially homogeneous and anisotropic Bianchi Type-V universe filled with interacting dark matter and holographic dark energy. The exact solutions of Einstein’s equations are obtained by using the variable deceleration parameter in the form a(t)=(sinh(at))1/n (Chawla et al. [1]). The physical properties of the model are obtained and discussed in details.

The Cosmological Constant: 2nd Order Quantum-Mechanical Correction to the Newton Gravity

Piero Chiarelli
The work shows that the associated Einstein-like gravity for the Klein-Gordon field shows the spontaneous emergence of the “cosmological” pressure tensor density (CPTD) that in the classical limit leads to the cosmological constant (CC). Even if the classical cosmological constant is set to zero, the model shows, that exists a residual theory-derived quantum CPTD. The work shows that the cosmological constant can be considered as

Derivation of Hubble’s Law and the End of the Darks Elements

Joao Carlos Holland de Barcellos
From the “Decreasing Universe” model, establishing the contraction of space tissue when exposed to a gravitational field, we derive the Hubble Law and, from there, we will explain the effects “Dark Energy” and “Dark Matter”.

Wave Functions, Creation and Annihilation Operators of Quantum Physical System

Malkhaz Mumladze
In this article we proposed derivation of the wave function of a quantum system from the functional representation of the state of this system. There is considered representation of creation and annihilation operators by boundary and co-boundary operators of chain and co-chain complexes on the physical space.

Dark Matter: SO-2’s Gravitational Redshift Could Give an Important Clue to Solve the Dark Matter Mystery

Stéphane Le Corre
The star SO-2 at the galactic center was recently at its closest distance to the supermassive black hole (SMBH). It allowed measuring relativistic effects. The observations confirm that the general relativity is the best gravitational theory compared to other alternative theories [1]. But although an excellent agreement with the observations is obtained all along the orbit, a discrepancy in the redshift of SO-2 is measured at its

A Snapshot of a Homogeneous Spinning Universe

Barbaro Quintero-Leyva
A snapshot of the circular speed as a function of the radius in a spin-ning-homogeneous spherical universe was obtained using a mass-dependent characteristic-acceleration in the Modified Newtonian Dynamics (MOND paradigm as a modified 2nd law of Newton) with and without considering the impact of the relativistic speed. To consider the impact of the relativistic speed the Extended Newtonian Theory (E

The Quantization Relations for the Metric Tensor of Gravitons

Piero Chiarelli
By using the gravity equation for quantum mechanical systems that takes into account the non-local interaction of the quantum potential the paper derives the quantization of the graviton in the limit of weak gravity. The output of the theory shows that, in the non-Minkowskian quantum approach proposed, where the coupling between the gravitational equation and the field is explicitly defined, a massless boson fie
