Challenging Established Physics
Questioning the tenets of established physics has led to groundbreaking inquiries into the nature of gravity. The episode discusses how the traditional view, particularly shaped by Einstein's general relativity, is being scrutinized, particularly the assumption that gravity cannot have mass. This exploration stems from attempts to explain cosmic phenomena, such as the universe's accelerating expansion. The idea of 'massive gravity' emerges as a promising solution to longstanding problems like the cosmological constant issue, which has perplexed scientists for nearly a century.
