This last model proposes that before the explosion (unique), all the matter and the energy of the universe were contained in a singularity, in a small point that he was quiet in the space eternally until the moment previous to being detonated. This model proposes a paradox: The objects at rest – as the initial singularity – they are in the same state, to less than than they act under an external force; Then, since the starting point contained all the matter and the energy, and nothing (at least nothing natural) existed outside this singularity what could it have caused that explodes? The simplest resolution of the paradox is that something supernatural caused that the universe exists. The abierto model of the universe implies a supernatural creator – a God. The Theory of relativity In 1916 Albert Einstein spread its first rough draft on its general theory of relativity, and the scientific world was affected remarkably. It seemed that Einstein was developing the deepest secrets of the universe.
Their equations also caused to some problems – technical dilemmas, mathematical problems – but not the type of things that would interest to him to newspapers or the more popular scientific magazines. Two scientists noticed the errors. Later in 1917 Danish astronomer Willem de Sitter, reviewed the theory of relativity and he in detail responded to Einstein, stressing to him the problem to him and offering a radical solution to him: general relativity could only work if all the universe exploded, going in all directions, from a central point. Einstein never responded to the critic of Sitter. Later, in 1922, the Soviet mathematician Alexander Friedmann independently reached the conclusion of Sitter. If Einstein were right – Friedmann it predicted – the universe would have to be expanding in all directions of a high speed. Meanwhile, astronomer Vesto Slipher was witness of the explosive movement of the universe.
