The James Webb Space Telescope has found a lonely black hole in the early universe that’s as heavy as 50 million suns. A major discovery, the object confounds theories of the young cosmos.

Hundreds of physicists (and a few journalists) journeyed to Helgoland, the birthplace of quantum mechanics, and grappled with what they have and haven’t learned about reality.

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go to the ends of space and time to find a fix.

The physicist Sidney Nagel delights in solving mysteries of the universe that are hiding in plain sight.

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.
