Hubble’s Constant and Flat Rotation Curves of Stars: Are Dark Matter and Energy Needed?

Abstract

Although dark energy and dark matter have not yet been detected, they are believed to comprise the majority of the universe. Observations of the flat rotation curve of galaxies may be explained by dark matter and dark energy. This article, using Newton’s laws and Einstein’s theory of gravitation, shows that it is possible to define a new term, called E 0 , variable in time and space, of which one of its limits is the Hubble constant H 0 . I show that E 0 is strongly linked to an explanation of the flat rotation curve of galaxies. This strong correlation between Hubble’s constant H 0 and E 0 enables us to solve the mystery of the surplus of gravity that is stabilizing the universe.
