This abstract was translated from A Teoria da Grande Explosão, o Big Bang
One of the scientific theories more accepted to explain the origin of the universe is the theory of Big-Bang or the Great
Explosion. In 1916 Albert Einstein it published the theory of relativity, where it said that the universe would be if expanding or then if contracting, opposing the idea of that the universe would be static or inert, accepted until then. From then on, diverse research had been made with the aid of telescopes, and the scientists had been able to deduce that the universe really was become enlarged, however in ordeiro way. To understand the idea of Big-Bang we must make the contrary way. That is, if instead of the universe if to expand the all moment, it was contracted. All the universe would converge, until coming back to an only point of origin, the initial point of substance. The universe has the one 15 20 billion years behind did not exist, nor the empty space, not even the time. Everything what had was a small sphere extremely, of the size of the tip of a needle. E this pontinho has about 18 billion years if would have blown up forming the current universe. This Explosion happened in a fraction of seconds, inflating the universe in a very superior speed to the one of the light. This explosion caused the expansion of the universe, which is observed until the current days, what the theory brings great reinforcements of Big-Bang. After Big-Bang and from the substance proceeding from it, had been if forming the constellations. The planets if would have formed from cosmic cloud remaining portions that had appeared the great explosion after. But, although to be a trend to invest in the theory of Big-Bang, we have to consider that the argument that endorses it can be a regional phenomenon. That is, this expansion is happening only in the limits observed of the universe, until the reach of the most powerful telescope, the Hubble. Ahead of this the possibility of this phenomenon exists not to take care of the universe all. In this in case that, what until today it was observed would be only a process of regional dilatação of still unknown cause.
