Dark Matter in Galaxies and Lambda-CDM Universe
Résumé
This article presents the results of our research on a multifaceted Centennial problem of the apparent inability of Newton’s gravity to treat observations of galaxies and their hierarchical structure by Kepler’s laws. The suspected cause is “Dark Matter” (further, Galactic Dark Matter, - GDM), which is invisible but interacts with the ordinary one through Newton’s gravity. However, misapplying Newton’s theory is not excluded: there are cases demonstrating galactic observations in terms of GDM-free Keplerian orbits. We revisited this problem in all aspects and scrutiny and found its hidden roots in compromised conceptions of Kepler’s orbits and mass-to-light ratio Υ. Consequently, we developed an approximate algorithm for treating galactic observations in the Newtonian gravitation framework and demonstrated its success. We also considered observations on a cosmic scale for a possible interplay of GDM with Cold Dark Matter (CDM) and other parameters of the Lambda-CDM Cosmology. The conclusion is made that GDM and CDM were introduced for different reasons and our findings for GDM do not necessarily affect the Cosmological Model.
