Like the little boy has seen the light. Cut from one face in the mirror to another. It is some time late in the night of 18 January or early in the morning of 19 January, 1996. We are in the bathroom of a Bel-Air mansion, and this guy, Don Simpson, is sitting on the john. He seems half asleep. A book slides off his lap - the latest biography of Oliver Stone.
The model of the universe's expansion is known as the Big Bang. As of 2015, this expansion is estimated to have begun 13.799 Â± 0.021 billion years ago. It is convenient to divide the evolution of the universe so far into three phases.t the time of this singularity, the expansion rate of the universe will reach infinity, so that any and all forces (no matter how strong) that hold composite objects together (no matter how closely) will be overcome by this expansion, literally tearing everything apart.
This point, later called the big bang, was the beginning of the universe as we understand it today. The expanding universe is finite in both time and space. The reason that the universe did not collapse, as Newton's and Einstein's equations said it might, is that it had been expanding from the moment of its creation. The universe is in a constant state of change.
