NEW PODCAST EPISODES
Primordial gravitational waves turn to dust and why this is good news for inflation theory; Julian Barbour's model in which the big bang created twin mirror universes, solves the arrow of time problem; & Paul Davies on his physics-based evolutionary-model of cancer, which recommends oxygen treatment and immunotherapy.
