0:00.0	To be honest, I was certain I had made a mistake.
0:02.0	I really, I remembered going through it over and over again.
0:05.0	It simply doesn't make sense.
0:07.0	What if everything we thought we knew about gravity was wrong?
0:13.0	What if the symmetries of Einstein's beautiful general relativity are broken at the fundamental level?
0:20.0	We've been told that gravity is just the curvature of space-time and not of force, but are we
0:26.5	misguided?
0:27.5	In this episode, we plunge into the world of massive gravity with Professor Claudia
0:33.6	DeRam, a theoretical physicist at Imperial College London, and author of The Beauty of Folly.
0:40.3	Professor Derram has upended decades of scientific consensus with her recent radical theory, suggesting that gravity itself may have mass,
0:50.3	an idea that was long thought impossible.
0:53.3	What does this mean for our understanding of the universe?
0:59.6	Hey.
1:00.4	Professor, please tell me what's something about gravity
1:03.5	that most physicists hold as an assumption that you think is deeply mistaken?
1:08.6	Okay, that's a good one.
1:11.9	And I'm going to have most physicists against me now.
1:16.0	Okay, maybe there are two things which are probably related.
1:19.8	The first one is the assumption that generality and the understanding of gravity
1:25.0	as we have it at the moment, is based on Einstein's principles,
1:31.9	which are the pillars of modern science,
1:35.2	the pillars of general activity related to the equivalence principle.
