Major arguments against the Big Bang theory include the questions, “But what happened before the BB?” or “What was there before the BB?” and more theologically, “What or who caused the singularity which exploded in the BB?”

The theory of Conformal Cyclic Cosmology, going as it does, a long way towards answering these questions, has been developed by Professor Sir Roger Penrose of Oxford University and Vahe Gurzadyan of Yerevan State University in Armenia.

Professor Penrose has never been able to accept the basic inflationary concept of a cosmos developing from a single point.    His concept is that the present aeon, being the period since the most recent big bang, is just one of a series of aeons “where the remote future of the previous aeon somehow becomes the big bang of our aeon”.

This Conformal Cyclic Cosmology agrees with the concept that the present aeon bas been expanding and developing since the most recent big bang, but it removes the need to consider the possibility of a beginning to everything, since everything has always been there.    A lot of cosmological physics research, targeted at discovering what happened in the period immediately following the big bang, is rendered redundant if the big bang was just part of a much longer cycle of events.

A study of patterns of micro-wave radiation by Penrose and Gurzadyan has led to the development of their theory.     The study involved a detailed survey of 11,000 locations in a search to discover points where galaxies may have collided in the past.    Such collisions would have caused the black holes at their centres to merge, producing enormous shockwaves of energy.

Their survey produced 12 possible locations, each of which shows concentric rings of energy, sometimes as many as five, each representing a massive event in the past.    The “unexpected order in a vast sky of disorder” which these rings provide, suggests that each is evidence of pre-big bang events.

Professor Shaun Cole, a member of Durham University’s computational cosmology group has called the research “impressive” and “a revolutionary theory and there appears to be some data which supports it”.    

The theory of Conformal Cyclic Cosmology removes the need for questions relating to what came before the big bang, as the event was part of a continuing cycle of events.

Cole and Penrose feel that evidence which will eventually become available from the Planck telescope will make it possible to search for further cosmic material, of which detailed analyses might support CCC and produce more clarity on the cyclic theory.
