Carlo Rovelli on rethinking the nature of time

Theoretical physicist Carlo Rovelli describes how political activism and LSD opened his mind to a radically different way of thinking about time.

Carlo Rovelli is a theoretical physicist who became a household name when his book Seven Brief Lessons on Physics became an unexpected international bestseller. His concise, and poetic, introduction to the laws and beauty of physics has sold more than a million copies. He鈥檚 also a pioneer of one of the most exciting and profound ideas in modern physics, called loop quantum gravity.

Carlo Rovelli tells Jim al-Khalili how he first became interested in the nature of time when he took LSD as a young man. Later he became curious about the world of the almost absurdly small, where time has no meaning and space is grainy. He took seven years to complete his undergraduate degree, having spent a lot of time protesting against the political establishment, falling in love and travelling. All this rebelling taught him the value of seeing the world in a different way and the benefits of challenging the status quo. In the end he concluded it was easier, and more meaningful, to challenge Einstein鈥檚 understanding of time, than it was to overthrow the government.
