Gravitational Deflection of Celestial Bodies and Photons

Barbaro Quintero-Leyva
The gravitational deflection angle of celestial bodies travelling near the sun with large eccentricity was derived using the extended Newtonian theory (ENET) and Einstein general theory of relativity (GTR). It was found that the non-Newtonian gravitational deflection of celestial bodies for ENET is 1.5 times the prediction of GTR. The deflection angle of the photon however coincided with the light deflection of GTR. It was als

Researches on the Space-Time View of the Special Relativity

Jidong Zhu
For the last one hundred years, researches on Special Relativity have always been lively. Experiments concerned have been recorded in many articles. After a lot of reading, analysis of these articles and information, the author found that some classical experiments have indicated that the time dilation has not symmetric property, so the space-time view of the special relativity is wrong. According to the special relativity, observ

An Extended Newtonian Theory for Gravitational Bound Systems

Barbaro Quintero-Leyva
A physical fundament was derived to support the empirical correction to the balance between the force given by Newton 2nd law and Newton gravitation introduced previously by the author to account for the perihelion precession of Mercury. An equation was obtained that coincided in sign and magnitude with the Einstein perihelion shift when the 3rd law of Kepler was used to express the orbital period in term of the semi-major axis and the same level of accuracy was demanded. O...

On the Intrinsic Precession of the Perihelion of Planets of the Solar System

Barbaro Quintero-Leyva
By analytically solving a corrected balance between the force given by the Newton’s 2nd law and the Newton gravitational force in polar coordinates, an equation for the intrinsic (i.e. two-body problem) perihelion precession of the planets of the solar system was obtained that when the Kepler’s 3rd law is applied it coincides with the equation resulting from Einstein GTR.

A Cosmological Model and Modifications to Einstein’s Theory of Relativity

Jiancheng Liu
This paper studied the revisions to Einstein’s theory of relativity, introduced the concept of “size mass” and put forward the new relativity mass-velocity formula; and then it put forward Liu’s Cosmological Model, analyzed the nascence, birth and development of the universe, obtained the Universe Moving Equations, and calculated the present universe’s parameters; and it analyzed the conditions that a celestial body occurs the similar big bang and the model that the Galaxy occurred the second bi...

On the Intrinsic Precession of the Perihelion of Mercury

Barbaro Quintero-Leyva
The longitude of the perihelion advance of Mercury was calculated for the two and ten-body problem by using a correction to the balance between the force given by the Newton 2nd law of motion and the Newton gravitational force. The corresponding system of differential equations was solved numerically. The correction, that expresses the apparent mass variation with the body speed, has a trend that is different from those that usually appear in the electron theory and in the special the...

On an Optical Paradox in Special Relativity

Vladimir A. Leus
Special Relativity Theory (SRT) is from time to time subject to critical assaults. There are several logically deduced discrepancies inherent in SRT (paradoxes) which demand a scrupulous examination. In this paper a new thought experiment, including two frames of reference is presented. Two trains are hurtling in opposite directions past one another in a symmetrical manner, but substantially asymmetrical events occur. This consideration leads to a contradiction in the notion of “relativity of si...

Holographic Origin of Missing Mass and Cosmological Constant Related to Mass Defect in Semiclosed Friedman Universe

Noboru Hokkyo
A holographic origin of missing mass and extremely high value of Einstein’s cosmological constant Λ ~ 10122 in quantum cosmology, compared to observational data ≤ Λ ≤ 1, is sought and related to extremely large relativistic mass defect of gravitional semiclosure of Friedman universe joined to an asymptotically flat outer space.

Polytropic Bulk Viscous Cosmological Model with Variable G and Λ

R. K. Tiwari, Mukesh Sharma, Sonia Sharma

We consider a Bianchi type-I Polytropic bulk viscous fluid cosmological model with variable G and Λ. To get a deterministic model, it is assumed thatand ,
