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 Lense-Thirring 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 MOND-based theories. More concretely, we retrieve from GR the value of MOND parameter a 0~10 -8cm·s -...

The Tully-Fisher 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...

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...

Presented is an exploration into the operation of the Universe that begins with a single assumption, an empirical proposition accepted by virtually all theorists. The article then builds on this assumption (a fundamental process of expansion) by applying and integrating three important laws of physics that 20th-century scientists overlooked—namely those detailed in Parts 1, 2, and 4 in this series of articles. They are, respectively, 1) “The velocity differential propagation of light,” which pre...

The study of the dust structure around a clump of star forming region sp1 has been performed at 01.9° latitude in the Infrared Science Archive (IRAS) map. The two different fits images of 60 μm and 100 μm are downloaded from sky view virtual observatory and a clump is selected as a study region. The flux densities at different points have been calculated using Aladin software. By analyzing two different Flexible Image Transport System (FITS) images of 60 μm and 100 μm the average temperatur...
