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. Join us as we explore the true nature of gravity
