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?

Max Tegmark proposes that consciousness may be another state of matter in his talk at the 4th FQXi International Conference.

Sean Carroll questions conventional wisdom on quantum fluctuations, whether we might be disembodied "Boltzmann Brains" floating through space & eternal inflation leading to a multiverse, in his talk at the 4th FQXi conference.

"What is quantum information *really* good for?" Physicists William Wootters, Caslav Brukner, Andrew Briggs, Raymond Laflamme, Sorin Paraoanu & Gerardo Adesso discuss this question at FQXi's 4th International Conference in Vieques.
