Last year, an enormous map of the cosmos hinted that the engine driving cosmic expansion might be sputtering. Now physicists are back with an even bigger map, and a stronger conclusion.

In math and computer science, researchers have long understood that some questions are fundamentally unanswerable. Now physicists are exploring how even ordinary physical systems put hard limits on what we can predict, even in principle.

Heat is supposed to ruin anything it touches. But physicists have shown that an idealized form of magnetism is heatproof.

Three new species of superconductivity were spotted this year, illustrating the myriad ways electrons can join together to form a frictionless quantum soup.

A new experimental proposal suggests detecting a particle of gravity is far easier than anyone imagined. Now physicists are debating what it would really prove.

Curious connections between physics and math suggest to Latham Boyle that space-time may survive the jump to the next theory of reality.

A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the standard picture of how particles move.

A 1930s-era breakthrough is helping physicists understand how quantum threads could weave together into a holographic space-time fabric.

A mysterious phenomenon known as duality often leads to new discoveries in physics. This time, space-time itself can sometimes be two things at once.
