Information
Martin Rees is perhaps Britain's most renowned cosmologist. He was master of Trinity College, Cambridge, president of both the Royal Astronomical Society and the Institute of Physics, and has led the nation's foremost science institution, the Royal Society. Now, about to celebrate his eightieth birthday, Lord Rees talks to Chris Lintott about his career in science.
Lord Rees says he wasn't particularly interested in the night sky as a child and only pursued science at school because he found languages difficult. He also regretted reading maths at Cambridge, only finding his stride during his postgraduate studies, when he was taken on by Dennis Sciama to undertake research in astrophysics, leading to his PhD.
Rees's career spans what he calls a 'golden age' for astronomy. It began during a time when the origin of the universe was debated, when the flamboyant Fred Hoyle's 'steady state' theory was eventually put to the sword by the bookish Martin Ryle, using the new technology of radio astronomy – in part aided and abetted by a young Martin Rees, whose work on quasars helped deal the fatal blow.
Rees was a contemporary of Stephen Hawking and witnessed at first hand the excitement of seeing black holes elevated from a speculative concept to an integral part of our universe's evolution. Like many advances, including radio astronomy, it happened thanks to accidents in simultaneous progress. Work on radar during WWII led to advances in seeing the universe in non-visible wavelengths. Though they had been postulated in the 19th century, the reality of black holes arrived via Einstein's theory of relativity, combined with radio astronomy and Roger Penrose's genius for maths.
Time and again, over Rees's career, seemingly bizarre ideas in cosmology have turned out to have merit. Rees and his colleagues showed that 'dark matter' – a speculative 'fix' for inconsistencies in galaxy dynamics – is also essential to the understanding of how the early universe found form, giving the concept increased credibility.
One of science's most celebrated thinkers and writers, Rees has never been shy of engaging with difficult concepts. While the 'big bang' solved the question of our origin story, it also raises other questions such as 'what was there before the big bang?', and Rees enjoys considering the possibility that there are other universes, perhaps with the properties of our universe that gave rise to us, or perhaps wholly or partially different.
Lord Rees also discusses the search for extraterrestrial intelligence, noting that while complex life may arise or has arisen in the universe, the likelihood is that, given the massive timescales involved, we are almost guaranteed to co-exist. But this leads to the intriguing prospect that any intelligent civilisation, including our own, is likely to create artificial intelligences that will supersede us and may well be near-immortal.
While Lord Rees worries about the threats that AI and the misuse of technology poses to our civilisation, he sees a potentially bright future in terms of scientific discovery, citing international collaborations and technological advances that might see us answering some of the questions we consider today to be too difficult - like the start of the universe and black holes used to be not so long ago.
