On Phase Transitions in the Early Universe

Abstract

The continuous expansion of space since the Big Bang has been a great discovery of mankind. However, that continuous expansion is incomplete, as it fails to describe the physics at very high density and high energy of radiation quanta. In this paper, we provide a solution of that incompleteness problem by developing and analyzing a droplet model: Droplets of a dimension form and grow, as soon as the density falls below a corresponding critical density. At that dimensional phase transition, the light horizon increases in an extremely rapid manner. As a consequence, the horizon problem is solved.
