Gravity a Viscoelastic Mechanics of the Universe

Abstract

This paper mathematically proves that gravity is a viscoelastic property. From the Newton’s
law of gravitation, a viscoelastic equation is been derived which is similar to one obtained
from the Newton’s law of viscosity. From the viscosity equation, the present strain rate of the
universe is calculated, and at the same time the Hubbles constant for the expansion of
universe is converted into an equation of strain rate and both the values are compared. The
value obtained from the viscosity equation is in agreement with the Hubble’s constant. Also,
the equations derive are based on the Gough-joule effect of negative coefficient thermal
expansion of the space time fabric. Hence, the expansion of universe is explained as a viscous
flow of gravity caused due to yielding which was initiated during the inflation period after the
big bang.
