A Challenge to Control Gravity via Applying Electromagnetic Low-Frequency Radiation - Theory and Proposed Model Experiments

Including Vaidya metric into the model of Expansive Nondecelerative Universe allows to localize the energy of gravitational field. A term of effective gravitational range is introduced and classic Newton potential is substituted for Yukawa-type potential. It allows to allocate a typical frequency value to each gravitational field. Derived theoretical conclusions led us to investigate the effect of electromagnetic field with a precisely predetermined frequency and intensity on iron. We believe that under certain circumstances a decrease in iron gravitational mass should be observed. Two model experiments verifying the theoretical conclusions are proposed.

An Approach to Relate the Weak and Gravitational Interactions

Stemming from simple postulates of nondecelerative nature of the universe expansion and Vaidya metric application, the paper offers some dependences and relations between the gravity and weak interactions. It presents a mode of independent determination of the mass of vector bosons Z and W, and it derives the time of separation of electromagnetic and weak interactions. Comparisons of theoretically derived and experimentally obtained data indicate the relevancy of the used mode and provide a hint for further investigation.

Cosmological Consequences of the Yukawa Potential Involvement in Gravitational and Electromagnetic Fields Interaction Evaluated by ENU Model

Model of Expansive Nondecelerative Universe (ENU) due to involving Vaidya metric makes it possible to localize the energy density of gravitational field. This its capability allows for answering several open questions and supporting (or contradicting) results obtained using different theoretical approaches. This paper is aimed to contributing to a solution of some cosmological problems, in particular those linked to the Yukawa potential consequences, independent way of dark matter estimation, ionospheric F2 layer behaviour, and cyclotron radiation.

Electromagnetic Influence on Gravitational Mass - Theory, Experiments, and Mechanism of the Solar Corona Heating

Based on the model of Expansive Nondecelerative Universe, the aim of the present contribution is to contribute to the theoretical rationalization of some experiments, in particular of those performed by Podkletnov and de Aquino and devoted to the gravitational mass cessation, to offer a mechanistic explanation of the Solar corona heating, and to propose an experiment to verify the explanation of the heating in the Earth conditions.

Neutron stars properties viewed by the ENU model

Up-to-now known characteristics of radio pulsars, such as mass limits, magnetic field intensity, rotational period, and maximum radiation are mainly of empirical nature. Applying the Expansive Nondecelerative Universe model (ENU) into the issue allows to offer a deeper theoretical explanation of the known parameters and to estimate their limits. Using the ENU approach the following values related to synchrotron radiation emitting radio pulsars were estimated: the lower and upper limits of magnetic field intensity are B(min) = 8.6 x 10^6 T, and B(max) = 9.4 x 10^8 T, respectively, the maximum rotation period reaches 3.9 s, the maximum radiation output of a pulsar is P(max) = 5.6 x 10^29 W (all the values relate to radio pulsars with 1.4 solar masses and radius 1.0 x 10^4 m and are mass and radius dependent). These values are in accordance with the experimental observations.

Formation of Complex Matter Structures and Mutual Relations Between the Mass of Elementary Particles

The model of Expansive Nondecelerative Universe leads to a conclusion stating that at the end of radiation era the Jeans mass was equal to the upper mass limit of a black hole and, at the same time, the effective gravitational range of nucleons was identical to their Compton wavelength. At that time nucleons started to exert gravitational impact on their environment which enabled to large scale structures become formed. Moreover, it is shown that there is a deep relationships between the inertial mass of various leptons and bosons and that such relations can be extended also into the realm of other kinds of elementary particles.

Analysis of Podkletnov's Phenomenon Based on Expansive Nondecelerative Universe

Owing to Vaidya metric including, the model of Expansive Nondecelerative Universe (ENU) is able to localize gravitational energy. Based on the quantification of gravitational field of the Earth, ENU allows to rationalize and quantify the effects of a superconductor-based high voltage impulse gravity generator constructed by Podkletnov. The differences in energy effect observed for two generators used are explained and improvement of the experiment arrangement is proposed.

Thermodynamics of Expansive Nondecelerative Universe

The present contribution deals with thermodynamic aspects of the model of Expansive Nondecelerative Universe. In this model, in the matter era a dependence T^CBR ~ E^CBR ~ a(exp -3/4) holds for the energy of cosmic background radiation, E^CBR and its temperature T^CBR, while the proportionality of the energy density epsilon^CBR to the gauge factor a can be expressed as epsilon^CBR ~ a(exp -3). The given relationships comply with experimental observations of the cosmic background radiation as well as with a surprising finding that the Universe expansion is not decelerated by gravitational forces. It is rationalized that the specific entropy is proportional to a(exp -1/4), i.e. it is gradually decreasing in time.

Cosmological Constant, Quintessence and Expansive Nondecelerative Universe

Recent observations of the Universe have led to a conclusion suppressing an up-to-now supposed deceleration of the Universe caused by attractive gravitational forces. Contrary, there is a renaissance of the cosmological member lambda and introduction of enigmatic repulsive dark energy in attempts to rationalize a would-be acceleration of the Universe expansion. It is documented that the model of Expansive Nondecelerative Universe is capable to offer acceptable answers to the questions on the Universe expansion, state equations of the Universe, the parameter omega, the cosmological member lambda without any necessity to introduce new strange kinds of matter or energy being in accord with the fundamental conservation laws and generally accepted parameters of the Universe.

Coincidence of the Universe Description Stemming from D-branes Theory and ENU Model

The contribution provides a comparison of consequences stemming from D-brane theories and Expansive Nondecelerative Universe model, and calls attention to coincidence of the results arising from the mentioned approaches to a description of the Universe. It follows from the comparison that the effects of quantum gravitation should appear at the energy near to 2 TeV.

The components are identical to those calculated by Virbhadra.

Localization of gravitational energy and its potential to evaluation of hydrogen atom properties

Vaidya metric as an integral part of the Expansive Nondecelerative Universe (ENU) model enables to localize the energy of gravitational field and, subsequently, to find a deep interrelationship between quantum mechanics and the general theory of relativity. In the present paper, stemming from the ENU model, ionisation energy and energy of hyperfine splitting of the hydrogen atom, energy of the elementary quantum of action, as well as the proton and electron mass are independently expressed through the mass of the planckton, Z and W bosons and fundamental constants.
