Black hole. Two rather mild and trivial words in themselves, but put them together and you have the stuff that physics, astronomy and sci-fi dreams are made of. Indeed, black holes seem to evoke similarly enthusiastic reactions from astronomers, cosmologists and laypeople alike. The mere thought of these behemoth regions of space–time – shrouded in fire, consuming everything within reach, including light – inspires interest like few other phenomena in the natural world, especially one that is deeply complex to comprehend.
It was only last month that the Nobel committee awarded the 2020 physics prize to Roger Penrose, Reinhard Genzel and Andrea Ghez for their work on black holes: Penrose “for the discovery that black-hole formation is a robust prediction of the general theory of relativity”, and Genzel and Ghez “for the discovery of a supermassive compact object at the centre of our galaxy”. So for all of you with black holes on the brain, physicist John Moffat’s latest book, The Shadow of the Black Hole, may be just the ticket. Moffatt, a veteran cosmologist, is now professor emeritus of physics at the University of Toronto and a member of the Perimeter Institute for Theoretical Physics. This is his fourth ...
