The Spacetime Revolutionary
Carlo Rovelli describes how black holes may transition to "white holes," according to loop quantum gravity, a radical rewrite of fundamental physics.

Rescuing Reality
A "retrocausal" rewrite of physics, in which influences from the future can affect the past, could solve some quantum quandaries—saving Einstein's view of reality along the way.

Untangling Quantum Causation
Figuring out if A causes B should help to write the rulebook for quantum physics.

In Search of a Quantum Spacetime
Finding the universe's wavefunction could be the key to understanding the emergence of reality.

Individual Stories
BICEP2 v Planck v Inflation theory
Astrophysicist Andrew Liddle discusses the new analysis from Planck that suggests that the BICEP2 signal could have been caused by dust, not gravitational waves -- and why if they did pick up gravitational waves, this is bad news for inflation theory.
