It has been demonstrated that dark matter (DM) can theoretically be completely explained by a natural effect of General Relativity (GR) without exotic matter, the LenseThirring effect that exists exclusively in GR and that would be due to the clusters of galaxies. In this study, we show that this explanation of DM leads to a modelization that can be interpreted as MONDbased theories. More concretely, we retrieve from GR the value of MOND parameter a _{0}~10 ^{8}cm·s ^{}...

This research seeks to understand the fundamental properties of matter, such as mass, charge, and spin, and how they interact with each other. By studying the behaviour of these particles in different environments, scientists can gain insight into the nature of the universe. This research also has implications for our understanding of dark matter and dark energy, which are believed to make up the most of the universe’s mass but remain largely mysterious. Additionally, this research may provide c...

The TullyFisher law M ∝ v ^{α} is an empirical relationship between the mass of a galaxy and its asymptotic rotation velocity. The purpose of this research is to demonstrate that this relation can be theoretically obtained in General Relativity (GR) with a particular solution of dark matter (DM) in very good agreement with the observations. Several years ago, it was demonstrated that DM can theoretically be completely explained by a natural effect of GR without exotic matter, ...

It has been demonstrated that dark matter can theoretically be completely explained by a natural effect of General Relativity (GR) without exotic matter or exotic correction as MOND, an effect that exists exclusively in GR and which is traditionally considered negligible. We give the values of this effect necessary to fully explain the dark matter component. In the framework of GR, this solution is mathematically as valid and legitimate as the hypothesis of an “ad hoc” addition of exotic materia...

We introduce the concept of equivalent electromagnetic (EEM) field, on the basis of which we describe the gravitational field (Gfield). We determine this EEM field based on the principle of equivalence (PE), i.e. by direct application of PE in the field equations and in the equations of motion, by introducing the EEM field potential. In this way, we introduce the mathematical formalism of the electromagnetic (EM) field into the Gfield equations. This procedure of describing the Gfield has a l...

This paper proposes a physical solution to primordial inflation. It occurs by a scalar field with a slowrolling period. It starts at the phase transition giving rise to the gravitational interaction at time t_{i} ~ 10 ^{44 }s, Planck time, and ends at time t_{f} ~ 10 ^{42 }s (or more exactly about 70 efolds later). This scalar field is carried by a primordial particle of inert mass m_{p} ~ 1...

In this article, it is shown that if a particle is at rest and has some harmonic oscillation, then a traveling particle with a constant speed corresponds to a De Broglie Wave. In 1924, De Broglie proposed that particles of matter exhibit wave like behavior, the expression for which became fundamental in the creation of wave mechanics (quantum mechanics). The main equation for this is the Schrödinger equation, which in the case of free motion of a particle becomes the expression for the De B...

Stars are light years away, and their brightness depends on multiple variables. Starting in the 20th century, artificial satellites were launched that added to the bright bodies of the observable sky. From 26.816 satellite observations and 9.037 stars visible to the naked eye, regression models were made between brightness and distances. The existence of a visual convergence plane that receives light photons arriving with a delay, c = 299.792.458 m·s ^{1} was assumed. Under the principle...

This paper introduces a new way to calculate gravity force from mass total energy, instead of from matter of mass. By introducing total energy (E1 and E2) of the two objects into Newton’s gravitational theory, Newton’s gravitational formula can be modified from F = GM _{1}M _{2}/r ^{2} as F = GE _{1}E _{2}/(C ^{4}r ^{2}). E _{1} and E _{2} are the total energy of the two objects and C is the light speed. Then this formula can be furt...
