Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

For years, physicists treated an Earth-to-space quantum uplink as a beautiful idea that nature simply would not allow. Now a set of detailed models and experiments suggests that the same fragile ...

Astrid Eichhorn spends her days thinking about how the laws of physics change at the tiniest scales. Imagine zooming in closer and closer to the device on which you’re reading this article. Its ...

Wormholes may help solve a major physics paradox, the conflict between quantum mechanics and general relativity. The “direct-sum quantum theory” views spacetime as distinct but related regions.
