Can We Break the Universe?
Sep 15, 2026 · 21m
Summary
This episode explores famous special relativity paradoxes, including the twin and ladder paradoxes, using spacetime diagrams to resolve apparent contradictions. It extends these concepts to a closed universe, demonstrating why a near-light-speed spaceship does not collide with itself despite length contraction. The host also addresses viewer questions on quantum mechanics interpretations and shares a research update validating cryptochrome-based magnetoreception in cells.
