The Race to a Habitable Exoplanet - Time Warp Challenge | Space Time
Summary
This PBS Space Time episode explores the theoretical link between faster-than-light travel and time travel using Lorentz transformations and spacetime diagrams. The host presents a "challenge question" involving a race to a distant exoplanet, where an FTL ship overtakes a sub-light vessel. Listeners are tasked with drawing worldlines to demonstrate how the FTL journey appears as backward time travel from the slower ship's perspective, proving that exceeding the cosmic speed limit inherently demands causality violations.
