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.
Some scientists believed that if our universe was created by a singularity, there would have to be a background heat still in existence in the universe. To understand why a scientist would think there is still heat from the big bang you have to know that the universe is still expanding.n other words, the big bang was the beginning of everything. The big bang theory is not the only model that tries to explain the origins of our universe. There are several other theories, but the big bang is the most popular and well known. Here is a link the the NASA page about the big bang theory.
