Ask someone how the universe began and may respond to these three familiar words: the big explosion. But in the sixties of the last century, cosmologists discussed this issue. On the other side of the argument to the big explosion, the idea of a “stable” world was not changing, and whose density was kept as it is by adding a new material constantly with its expansion.
In the end, the observations excluded the idea of the stable universe and prepared the place of the big explosion in the law of cosmology. This primitive explosion has started the process of continuous expansion, and today cosmologists view the universe as a place for the continuous flow.
But now a bold group of cosmologists question all of this. To be clear, this is not a return to the world of stable condition, but something more interesting. Researchers suggest that the history of the universe may be permeated by strange seizures. These periods of cosmic recession can arise in a way that replaces a whole era of traditional cosmic history or is divided into this schedule.
Bold is definitely the word of this hypothesis. “He refers to a completely different family of the possibilities that we did not realize,” he says. Adrian Erickik At the University of North Carolina in Chaplin Hill, who did not participate in the work. But if these static periods exist, they can solve all kinds of languages, including what dark matter is. Even more exciting, these ideas may be tested soon …
