Bubble Bubble Toil And . . .

The theory that our universe is contained inside a bubble, that multiple alternative universes exist inside their own bubbles, the ‘multiverse’  is  for the first time, being tested by physicists. Two Theories, Two Teams of Researchers. Eternal Cycle vs Bubble Theory!

The inflationary paradigm has been very successful at explaining the initial conditions giving rise to our observable universe. Turning back the clock even further, considering the initial conditions forinflation itself leads to the surprising possibility that ourobservable universe might only be a tiny piece of a vastmultiverse, the majority of which is still undergoing ac-celerated expansion. In this scenario, known as eternal-inflation, our observable universe resides inside a single bubble nucleated out of a false vacuum of space. The rate of bubble formation is outpaced by the accelerated expansion of theinflating false vacuum, and therefore inflation does notend everywhere.

According to inflationary theory, the universe started from a point of infinite density known as the Big Bang about 13.7 billion years ago, expanded extremely rapidly for a fraction of a second and has continued to expand much more slowly ever since, during which time stars, planets and ultimately humans have emerged. That expansion is now believed to be accelerating and is expected to result in a cold, uniform, featureless universe.

OK, WE HEAR YOU! Two points . . .

Firstly English, Got It.

Secondly, lets step back a couple of years to December 2010:

Revered mathmatical physicist Roger Penrose at University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang. Penrose claims that the circular patterns seen in the Wilkinson Microwave Anisotropy Probe mission data on the Cosmic Microwave Background suggest that space and time perhaps did not originate at the Big Bang but that our universe continually cycles through a series of aeons, and we have an eternal, cyclical cosmos. He also refutes the idea of inflation, a widely accepted theory of a period of very rapid expansion immediately following the Big Bang. An extraordinary discovery, evidence of something that occurred before the Big Bang. Penrose says this is exactly what you’d expect if the universe were eternally cyclical. Each cycle ends with a big bang that starts the next cycle. Read the full article »»»»
