‘Cosmic inflation’: did the early cosmos balloon in size? A mirror universe going backwards in time may be a simpler explanation
Neil Turok is the inaugural Higgs Chair of Theoretical Physics at the University of Edinburgh. He holds the Roger Penrose Visiting Professorship at Perimeter Institute for Theoretical Physics in Canada where he is emeritus Director. Before that he was Chair of Mathematical Physics at Cambridge and Professor of Physics at Princeton.
Neil’s day job is developing and testing fundamental physics theories of the universe. His first-principles predictions of correlations between the temperature and polarisation of the cosmic background radiation (CBR), and the CBR and the galaxy distribution have been confirmed at high precision. His work also ruled out several popular theoretical models. Recently, he showed how a CPT-symmetric universe could provide the simplest-yet explanation of the cosmic dark matter, the large scale properties of the universe and the primordial density variations.
In 2008 Neil won the TED prize for his research and for AIMS. In 2016 he was made an Honorary Fellow of the UK Institute of Physics and was awarded the John Torrence Tate Medal of the American Institute of Physics for International Leadership in Physics. In 2018 he was appointed an Officer of the Order of Canada.
