The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.

Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff.

In a quest to map out a quantum theory of gravity, researchers have used logical rules to calculate how much Einstein’s theory must change. The result matches string theory perfectly.

The James Webb Space Telescope has the potential to rewrite the history of the cosmos and reshape humanity’s position within it. But first, a lot of things have to work just right.

Syukuro Manabe and Klaus Hasselmann have been honored for their work that led to reliable predictions of the effects of climate change. They will share the Nobel with Giorgio Parisi, who has made pioneering studies of chaotic physical systems.

Investigations of the simplest possible clocks have revealed their fundamental limitations — as well as insights into the nature of time itself.

The five-decade-old paradox — long thought key to linking quantum theory with Einstein’s theory of gravity — is falling to a new generation of thinkers. Netta Engelhardt is leading the way.

Like a perpetual motion machine, a time crystal forever cycles between states without consuming energy. Physicists claim to have built this new phase of matter inside a quantum computer.

For 50 years, mathematicians have believed that the total number of real numbers is unknowable. A new proof suggests otherwise.
