Claudia de Rham on playing with gravity

Claudia de Rham on playing with gravity

Author: BBC Radio 4 June 17, 2025 Duration: 28:21

Claudia de Rham has rather an unusual relationship with gravity.

While she has spent her career exploring its fundamental nature, much of her free time has involved trying to defy it - from scuba diving in the Indian Ocean to piloting small aircraft over the Canadian waterfalls. Her ultimate ambition was to escape gravity’s clutches altogether and become an astronaut, a dream that was snatched away by an unlikely twist of fate.

However, Claudia has no regrets - and says defying gravity for much of her life has helped her to truly understand it.

As Professor of theoretical physics at Imperial College London, she now grapples with deep mathematics, where the fields of particle physics, gravity and cosmology intersect, on a quest to understand how the universe really works. She is a pioneer of the theory of massive gravity, a theory which could take us beyond even Einstein’s theory of relativity and shed light on why the universe is expanding at an ever-increasing rate.

Presented by Jim Al-Khalili Produced by Beth Eastwood


Hosted by physicist and author Professor Jim Al-Khalili, The Life Scientific offers a rare and intimate glimpse into the minds shaping our world. Each conversation moves beyond the standard lecture or interview, weaving together personal history with groundbreaking ideas. You’ll hear how childhood curiosity, unexpected setbacks, and moments of sheer luck have steered the careers of some of today's most influential researchers. This BBC Radio 4 podcast treats science not as a remote collection of facts, but as a deeply human endeavor driven by passion, perseverance, and sometimes, serendipity. The discussions delve into the real process of discovery-the late-night frustrations, the collaborative breakthroughs, and the ethical questions that arise from new knowledge. While exploring everything from the smallest particles to the vastness of the cosmos, the core of each episode remains the individual behind the science. Listeners come to understand not just what these scientists know, but who they are and what continues to drive them forward. It’s a series that connects the personal to the universal, making complex fields accessible and profoundly relevant. By focusing on the life as much as the science, this podcast reveals how our future is being built, one question at a time, in labs, field stations, and offices around the globe.
