NEW PODCAST EPISODES
Watching Schrodinger's cat die; black holes bounce into white holes; sharpening Occam's razor; catching quantum pigeons; & generating quantum Cheshire cats.
Time travel is simulated in the lab; Alan Guth on the doubts clouding the BICEP2 result; how the Higgs should have destroyed the universe already; & could entropy explain why nature obeys quantum rules?
Andrei Linde and Joao Magueijo on the BICEP2 discovery of primordial gravitational waves; using thermodynamics to explain the origin of gravity; & is quantum entanglement the fundamental glue that binds reality together?
