Quick takeaways

Professor Claudia de Rham introduced a new theory of massive gravity to address the discrepancy between predicted and calculated amounts of dark energy in the universe.

Understanding the mass of fundamental particles, like the graviton, provides crucial insights into the origins of the universe, its accelerated expansion, and the cosmological constant problem.

Exploring extra dimensions, linked to string theory and theories like Kaluzak-Klein, offers new perspectives on gravity and space-time, contributing to a deeper understanding of the universe.

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.

Claudia de Rham is a Swiss theoretical physicist at Imperial College London. She is known for her work at the intersection of gravity, cosmology, and particle physics. She won the 2020 Blavatnik Young Scientist Award for reviving the theory of massive gravity and has made significant contributions to understanding dark energy, dark matter, and gravity. Her research focuses on modified theories of gravity, including massive gravity and Galileon gravity.
