Supersymmetric Particle Found?
Summary
This episode explores a potential anomaly in ANITA data where two high-energy radio bursts suggest particles passed through the Earth, possibly indicating the existence of supersymmetric staus. The hosts discuss how this hint of physics beyond the Standard Model offers a new avenue for testing supersymmetry, given the Large Hadron Collider's failure to find evidence. The segment concludes with viewer Q&A addressing the Casimir effect, string theory dimensions, and updates on the interstellar object Oumuamua.
