Sir Roger Penrose: Cosmic Inflation Is ‘Fantasy’
Sir Roger Penrose calls string theory a “fashion,” quantum mechanics “faith,” and cosmic inflation a “fantasy.” Coming from an armchair theorist, these declarations might be dismissed. But Penrose is a well-respected physicist who co-authored a seminal paper on black holes with Stephen Hawking. What’s wrong with modern physics—and could alternative theories explain our observations of the universe?
Roger Penrose is emeritus professor of mathematics at the University of Oxford in Oxford, United Kingdom.
