How parallel worlds interact with ours; redefining "life" in terms of predicting the future; questioning the founding assumptions of quantum theory; & the Philae lander sends back songs from a comet.
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.
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?
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.
The final part of our Year in Physics review, with Ian Durham; & could ancient aliens have thrived in the universe 15 million years after the big bang?
