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 ...

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 ...

As a symbol of Chinese YinYang theory, the implication of Tai Chi diagram has been widely acknowledged in Natural Sciences and Philosophy in both east and west. Taking three wellknown principles in physics for example, “the principle of complementarity”, “dissipative structure theory” and “Wheeler’s principle of austerity”, this paper interprets the symbolic representation of Tai Chi diagra ...

The present study deals with spatially homogeneous and anisotropic Bianchi TypeV 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 work shows that the associated Einsteinlike gravity for the KleinGordon 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 theoryderived quantum CPTD. The work shows that the cosmological constant can be considered as ...

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”.

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 coboundary operators of chain and cochain complexes on the physical space.

The star SO2 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 SO2 is measured at its ...

A snapshot of the circular speed as a function of the radius in a spinninghomogeneous spherical universe was obtained using a massdependent characteristicacceleration 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 ...

By using the gravity equation for quantum mechanical
systems that takes into account the nonlocal 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 nonMinkowskian
quantum approach proposed, where the coupling between the gravitational
equation and the field is explicitly defined, a massless boson fie ...
