New model of the universe scientists.

<P> It physorg site Jan. 31 report, University of North Carolina at Chapel Hill universe, physicists proposed the formation of a new model, the universe may be in constant expansion and contraction. .This theory to challenge the Big Bang theory, and solved a thorny modern physics problem. .Literature and the Academy of Sciences, University of North Carolina professor of physics at the famous Paul. Frampton and Dr. Lewis. J. Robin and graduate-Royce. Baum, co-sponsored a circular pattern, the cyclic model has four key parts: expansion, reversing ., contraction and bounce. .In the expansion, dark matter (of unknown cause the accelerating expansion of the universe energy) the promotion of non-stop until all the material can not be split into anything connected fragments. .Released from the black hole that everything is split into atoms. .Then the moment before the end of the expansion into the reverse phase. .</ P> <P> reverse phase, a large explosion in a reverse process, the pieces do not stick together again, but a fragment of each division and a self-contraction. .The formation of numerous separate pieces of the universe, the universe shrinking, and then rebound, similar to the way the big bang expansion to the outside again. .A fragment of which we formed the universe. .</ P> <P> Frampton said, "This loop numerous times, so that we can not know the exact start or end time. Therefore, in this cycle does not exist in the Big Bang." </ P> < .P> "Physical Review Letters" magazine will be published in the next midterm paper describes this model. .Frampton said that the twentieth century cosmologists first raised the thirties of the universe no beginning or end of the oscillation mode to replace the big bang theory. .Oscillation theory, including but not with the second law of thermodynamics in physics, including the match, this theory was eventually abandoned. .</ P> <P> second law of thermodynamics say that entropy can not disappear. .But if entropy oscillation to the next in a process of oscillation increases, the universe becomes larger after each cycle. .Frampton said, "the universe may be more mixed as mixed as the larger snowball. Each oscillation of the time will also last longer. Backstepping from the time, I am now shaking time before the universe will be very short. This .will inevitably lead to the production of the Big Bang. "</ P> <P> Frampton and Baum in the reverse phase by assuming that the residual entropy of all the fragments are too far apart and can not be effective to avoid the large mutual .explosion. .Each fragment is split into a separate universe, each universe can shrink the material and the basic entropy is empty. .Frampton said, "there will be any material on the contraction can not be overcome. Returned empty view is that this new cyclic model of the most important part." When he suddenly thought of last October, when the idea was very .shock. .He said, "I suddenly found a solution to this seemingly new method can not solve problems. I seat on the chair, legs on the table, half asleep in pondering this question. When I found this very .simple possibilities almost fall off my chair. "</ P> <P> </ p>.
