A world-renowned physicist seeks gravity’s true nature, and finds wisdom in embracing its force in her life.

Claudia de Rham has spent much of her life dedicated to exploring the limits and true nature of gravity. As she describes in her new book, The Beauty of Falling, de Rham trained to be a pilot and then an astronaut. To demonstrate gravity’s effects, New Scientist took her indoor skydiving at iFLY London, explaining how gravity acts on every cell of your body in the same way. Yet, gravity still isn’t fully understood. It doesn’t fit into the mould of the other fundamental forces, and quantum theory can’t yet explain it. For her part, de Rham has sought to make progress by thinking deeply about gravitons, the hypothetical carrier of the force of gravity. Each of the fundamental forces is carried by an equivalent "boson" particle – some have zero mass, others have a very small mass. De Rham wanted to know: what is the graviton's mass?

Measurements of a key parameter in cosmology do not agree. Is this the sign of exciting new physics, do we need to rethink some aspects of cosmology or is it just a measurement error? In this film, Nobel Prize winning physicist Adam Reiss, and George Efstathiou (who was the scientist chose to give the cosmology results for ESA's Planck Probe) are joined by astrophysicist Daniel Mortlock and theoretical cosmologist Claudia de Rham to discuss this latest puzzle for cosmology.

A special lecture hosted by Imperial Theoretical Physics and Imperial Institutional Events and chaired by Claudia de Rham to celebrate the naming of the Abdus Salam Library at Imperial. We welcome Professor Atish Dabholkar, the current Director of ICTP in Trieste, Italy, and Professor Brian Cox CBE, renowned science communicator as our key speakers. 

Conférence de Claudia de Rham, professeure au Imperial College de Londres et à la Faculté de sciences naturelles, Département de physique. La détection récente d’ondes gravitationnelles représente une nouvelle ère pour la science et une fenêtre ouverte sur notre Univers. Mais que savons-nous au juste sur le comportement de notre Univers et de la structure de l’espace aux échelles cosmologiques? Lors de cette conférence, il s’agira de voyager jusqu’aux extrémités de l’Univers observable et d’essayer d’éclairer les comportements de la gravitation. Il sera aussi question du rapport de la gravitation avec l’énergie sombre. Plusieurs observations ont trahi l’existence de cette dernière; elles montrent que l’Univers croît plus rapidement qu’il ne le devrait. Quelque chose de puissant s’oppose à la gravitation, quelque chose que les physiciens ont nommé l’énergie sombre. Comprendre la véritable nature de cette dernière, et son rapport avec la gravitation, devrait permettre de dessiner un scénario plus précis sur l’avenir de notre Univers lequel prendra peut-être la forme d’un grand déchirement.

The acceleration of the expansion of the universe is one of the fundamental questions in cosmology. Scientists believe that dark energy is driving and accelerating the expansion; however, there is a discrepancy between the predicted amount of dark energy in the universe and our theoretical calculations based on the properties of fundamental particles. To get to the bottom of this, today's guest, Professor Claudia de Rham, proposed a new theory of "massive gravity" that could solve this “impossible” riddle.  Join us as we explore the true nature of gravity and the beauty of falling!

Debate at the Hay-in-Wye Festival Institute of Arts and Ideas.

We have the impression that science unravels the mysteries of the universe. But with every mystery solved, a new mystery emerges. The Big Bang gave us an explanation for the expanding universe but left the mystery of how it came about. Quantum mechanics accounted for the strange behaviour of subatomic particles, but led to the puzzle of its conflict with relativity. Dark energy made sense of an accelerating universe but led to the mystery of why we have no evidence for it. Is there a danger that we are making a fundamental mistake in imagining science can eradicate mystery, and do we need to think of science differently as a consequence? 

Do we need to abandon the idea that science has the potential to provide a complete explanation?  Should we not expect science to eradicate mystery and instead simply require that its theories work well enough for our current aims and purposes?  Or is the ability to overcome mystery essential to the effective operation of science and a core idea responsible for its success?

Einstein's theory of general relativity has been our best understanding of gravity for over a century, withstanding a variety of experimental challenges of ever-increasing precision. But we have to be open to the possibility that general relativity -- even at the classical level, aside from any questions of quantum gravity -- isn't the right theory of gravity. Such speculation is motivated by cosmology, where we have a good model of the universe but one with a number of loose ends. Claudia de Rham has been a leader in exploring how gravity could be modified in cosmologically interesting ways, and we discuss the current state of the art as well as future prospects.

Hosted by Professor Alice P. Gast, this conversation will be with Professor Claudia de Rham, Professor of Theoretical Physics and Heba Jemal, 2nd Year Physics student. Throughout our history, we have gathered information from the Universe that surrounds us through the light it emits. We have seen the Universe through our own eyes and instruments. The direct detection of gravitational waves in 2015 has marked the beginning of a new era for science where we are now able to hear the Universe and communicate with it through a new channel. But how much do we actually know about gravity and how gravitational waves propagate? In this event we will discuss how gravitational waves can be used as a privileged channel of communication with the secret dark components of our Universe.
