We tour how general relativity can tilt the light cone and create closed timelike curves—paths that loop back to where and when you started. From Gödel’s rotating universe to Kerr black holes and Hawking’s chronology protection, we explore the physics, the paradoxes, and the ideas meant to keep causality safe. A brain-bending dive into the possibility—and the limits—of time travel in our universe.
