A new suggestion that complexity increases over time, not just in living organisms but in the nonliving world, promises to rewrite notions of time and evolution.

Quantum gravity could help physicists unite the currently incompatible worlds of quantum mechanics and gravity. In this episode, Monika Schleier-Smith discusses her pioneering experimental approach, using laser-cooled atoms to explore whether gravity could emerge from quantum entanglement.

Janna Levin is the director of sciences and chair of the Science Studios at Pioneer Works. She is also the Claire Tow Professor of physics and astronomy at Barnard College of Columbia University.

New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.

Astronomers are discovering that magnetic fields permeate much of the cosmos. If these fields date back to the Big Bang, they could solve a major cosmological mystery.
