Thanks to John Merryman for suggesting the topic of this post. Earlier this month, a team of astronomers led by Roger G. Clowes at the University of Central Lancashire reported the discovery of the largest structure seen in the universe, a clump of...




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.
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?
