The Geometry of Causality

The video explores the concept of causality in space-time, delving into Einstein's theory of relativity. It reviews special relativity, focusing on time dilation and length contraction. The video explains space-time diagrams, world lines, and hyperbolic contours, highlighting their role in understanding causality. It covers the Lorentz transformation and its significance in maintaining invariance across reference frames. Finally, it discusses causal geography and light cones, emphasizing the constraints of causality and the cosmic speed limit.
