The Geometry of Time Travel

Professor Ian Stewart FRS

Time travel was once the stuff of fiction, but today it is discussed with utmost seriousness by Physicists. What are they saying about it: is time travel possible, impossible or something in between?

Trying to find the answer to this relies on Einstein’s General Relativity mixed with a dose of Quantum Mechanics, but once we are armed with these, can we find a way forward (and backward) into time?
