A renowned scientist says he has spotted evidence that a universe existed before the Big Bang.
Professor Roger Penrose from Oxford University says concentric circles discovered in the background microwaves of the universe provides evidence of events that took place before the universe came into being.
The cosmic microwave offers us a ghostly look at the the universe just 300,000 years after the Big Ban’ – a microscopic amount of time compared to the universe’s estimated age of 13.7billion years.
The research by Penrose, who was awarded the 1988 Wolf Prize along with Stephen Hawkings for adding to our cosmic knowledge, adds evidence to the theory that the universe has expanded (‘the Big Bang’) and contracted (‘the Big Crunch’) many times.
The cosmic radiation background (CMB) is believed to have cooled to a temperature of -270C in the near 14 billion years since the birth of the universe.
Stars and galaxies started to form around 300 million years later. Our Sun was born around five billion years ago, and life first appeared on the Earth around 3.7 billion years ago. …
