Quantum Physics in a Mirror Universe
Sep 14, 2026 · 22m
Summary
This episode explores parity symmetry, explaining how the weak nuclear force violates this mirror-image symmetry. It details the tau-theta puzzle and Chien-Shiung Wu’s 1957 cobalt-60 experiment, which proved that left- and right-handed particles behave differently. The discussion concludes with listener comments on the panspermia hypothesis, debating whether life originated on Earth or arrived via natural or directed interstellar transport.
