Can maths prove the existence of aliens?

Published: Nov. 11, 2023, 6 a.m.

Are we alone in the universe \u2013 and if not, how many other civilisations might there be? Remarkable images and data sent back to Earth by the James Webb telescope have given a new impetus to a well-worn debate. We ask how far mathematics \u2013 and in particular a famous equation called the Drake Equation \u2013 can be used to answer one of the most fundamental questions we face. Paul Connolly investigates with the help of Catherine Heymans, Astronomer Royal for Scotland and Professor at the University of Edinburgh and Bill Diamond, President and CEO of the SETI Institute in California.
