About this episode
The episode discusses the foundational frameworks of modern physics, focusing on General Relativity and quantum mechanics.
Modern physics rests on two foundational frameworks that describe our universe at different scales. The first is General Relativity, Einstein’s theory of gravity, which describes gravity not as a force but as the curvature of spacetime itself. Massive objects bend the geometry of spacetime, and this curvature dictates how all massive objects move, from planets to black holes. At the microscopic scale, we have quantum mechanics which describes the probabilistic nature of par...
