Geddankenexperiment Examining How Kinetic Energy Would Dominate Potential Energy, in Pre Planckian Space-Time Physics

Authors: Andrew Beckwith

Abstract. We use Padmabhan’s “Invitation to Astrophysics” formalism of a scalar field evolution of the early universe, from first principles, to show something which seems counter intuitive. How could , just before inflation, KINETIC energy be larger than potential energy in pre Planckian physics, and what physics mechanism is responsible for the Planckian physics result that Potential energy is far larger than KINETIC energy. This document answers that question, as well as provides a mechanism for the dominance of KINETIC energy in Pre Planckian space-time, as well as its reversal in the Planckian era of cosmology. the KE initially proportional to g times T ^ 4 power , with g the initial degrees of freedom and T the initial temperature just before the onset of inflation. Our key assumption is the smallness of curvature, as given in the first equation, which permits adoption of the Potential energy and Kinetic energy formalism used, in the Planckian and Pre Planckian space-time physics.

Comments: 5 Pages. Follow up to calculation of curvature paper, with emphasis upon Kinetic energy being totally dominant in the Pre Inflationary era
