Abstract

Dark energy is thought to be very homogenous, not very dense and it is not known to interact through any of the fundamental forces other than gravity. In this research work, we use analytical method to find a model that may possibly relate dark energy to gravitation. After some plausible analyses, we obtain a relation,   Capture3.PNG

where µ is Gravitational potential energy,  is the mass of galaxy,  is mass of earth, Λ is dark energy,  is receding velocity,  is Hubble’s constant and Ro  is the distance measured from the point of observation and the galaxy. Moreover, we estimate K =  Capture_2.PNGfor various galaxies, finally, the relation µ ∝ Λ, indicates a direct relationship between Dark energy and Gravitation.

Keywords:
Dark energy, gravitation, galaxy, redshift, negative pressure, universe and universe.
