Professor Roger Penrose was one of three scientists awarded this year’s Nobel prize for physics for their work on black holes. Penrose developed the conformal cyclic cosmology which states that the universe has already been created and destroyed at least once.
A US astrophysicist has denounced Nobel prize co-winner Sir Roger Penrose’s claim that at least one other universe existed before the Big Bang as “illegitimate”.
Professor Penrose’s conformal cyclic cosmology theory posits that the universe can, and has, been born and died many times over – as opposed to the currently-accepted idea that the universe will continue expanding forever.
But former Lewis and Clarke University professor and writer for Science magazine Ethan dismissed that idea in an article for Forbes magazine on Thursday.
Siegel went as far as to question Penrose’s scientific integrity, accusing him of “unsound and illegitimate” analysis.
Penrose believes ‘Hawking spots’ – large dark radiation-emitting patches detectable in the night sky – are the remnants of black holes from the demise of the previous cosmos.
“Our Big Bang began with something which was the remote future of a previous aeon and there would have been similar black holes evaporating away, via Hawking evaporation,” he told The Daily Telegraph this week.
Hawking spots are named after the late Professor Stephen Hawking, who theorised that black holes – so-called because not even light can escape their enormous gravity – leak radiation and slowly diminish to nothing.
“We have a universe that expands and expands, and all mass decays away, and in this crazy theory of mine, that remote future becomes the Big Bang of another aeon.”
Penrose shared this year’s Nobel prize for physics with Reinhard Genzel and Andrea Ghez for his decades of work in proving the existence of black holes and how they are formed.
