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. My guest, Professor Claudia de Rham, proposed a new theory of "massive gravity" that could solve this “impossible” riddle. Claudia 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.
