Box found in previous universes

Current cosmological theory is that the universe began 13.7 billion years ago with the Big Bang. But a legendary physicist says he found the first evidence of an eternal, cyclical nature of the universe.

According to the Big Bang theory, all of which today comprises the universe was once concentrated at the point of near-infinite density. Before the singularity (the universe, compressed into an infinitely small and dense point) exploded and, therefore, before the existence of the universe - there was absolutely nothing. It is not clear whether you can use a piece of "to" in respect of the universe that existed before the Big Bang, because time itself could then not exist at all. In the current model, the universe began with the Big Bang, endured for a fraction of a second of cosmic inflation (rapid expansion and cooling), which gradually slowed to a much slower expansion that is taking place in our day and will end only with the transformation of the universe in an infinitely extended, desert area.

Sir Roger Penrose, one of the most famous physicists of the last fifty years, disagrees with this development. He recalls that the universe began with a very low state of entropy, that is, it was from the start a very orderly manner. This is what makes possible the existence of a complex matter from which everything is made. He points out that the Big Bang can not explain why it was so harmoniously. In his opinion, this is due to the fact that our universe - is only one of many located in the cyclic chain, which then swell up, then back to decrease.

What does this mean? Penrose argues that at the end of its existence, the universe will return to a state of low entropy. This is because black holes suck in all matter, energy and information, which are found in their way, thus taking away the entropy of the universe (where it goes to the entropy, that is another question.) The continuing expansion of the universe will transform the universe, ultimately, into the cosmic desert, forcing even the black holes evaporate, which again will lead the universe in a highly ordered state. It will be ready to contract into a singularity and produce the next big bang.

This theory, of course, has the advantage, but that argument in her confirmation is not ... Rather not. According to him, Penrose found evidence to support his ideas, in the cosmic microwave background radiation, which passes through the whole universe was formed and, as previously thought, 300,000 years after the Big Bang, providing an insight into how the universe was in a distant time . Penrose, a colleague Vahe Gurzadyan opened the concentric circles composed of regions with a much smaller temperature range than anywhere else.

What does this mean? Penrose believes these circles are windows into the previous universe, spherical ripples left by the gravitational effect of a collapsing black holes in the previous universe. According to him, these circles do not fit into the current inflationary model in which all the temperature changes the background microwave radiation should be inferred.

Then the fun begins. If these groups do exist and indeed are those for which they accept Penrose, it means that he was able to refute the standard inflationary model. But this is still far away.

Inflation model unanimously adopted a very simple reason - it best explains our universe. Therefore, cosmologists with great skepticism would react to any research that would refute it. Most popular news informers tell the main news of the day.
