Scientists say they have discovered evidence that the universe existed before the Big Bang.
Concentric circles discovered in cosmic microwave background radiation (CMB) – the after-effects of the Big Bang – display evidence of events that took place before most scientists believe the universe came into being.
The controversial finding points to the existence of a universe that did not begin 13.7billion years ago, as is generally accepted, but is instead a cycle of so-called aeons.
The discovery has been posted online on the website arXiv.org by respected scientist Professor Roger Penrose from Oxford University and Professor Vahe Gurzadyan from Yerevan State University, Armenia.
Most scientists believe the universe was created in the Big Bang around 13.7 billion years ago. Stars and galaxies started to form around 300 million years later. Our Sun was born around five billion years ago, while life first appeared on the Earth around 3.7 billion years ago.
