"Cosmologists say they have found remnants of a bygone universe in the afterglow of the Big Bang found in the Cosmic Microwave Background (CMB).
The discovery gives weight to the controversial theory of Conformal Cyclic Cosmology, or CCC, that suggests our universe is just one of many, built from the remains of a previous one in the Big Bang 13.6 billion years ago.
The theory describes an eternal cycle of Big Bang events, repeating into the far distant future, the end of our universe giving rise to a new one.
A team led by Oxford University mathematics emeritus Roger Penrose, a former collaborator of the late Stephen Hawking, claims in a new paper lodged on the preprint server arXiv to have found signs of so-called Hawking Points, anomalous high energy features in the CMB.
Penrose and colleagues say that these anomalies were made from the last moments of black holes evaporating through “Hawking radiation”.
Conformal Cyclic Cosmology strongly conflicts with the current standard model explaining the evolution of the universe. “Unlike previous cyclic universe models, there is no ‘Big Crunch’ where everything comes together again,” explains Duffy. “Instead CCC links the similarity of the current accelerating expansion of the universe by dark energy with early expansion of inflation in the Big Bang.”
The results from Penrose and colleagues are likely to be met with skepticism by many mainstream cosmologists.
