Even if it turns out that time loops never take shape, studying them provides key insights into the deepest rules of reality.

Physicists are quietly rewriting the rulebook for how we might cross the gulf between stars, not by bolting bigger rockets to ...

Time travel has long lived in the realm of fantasy, but a growing body of research is quietly shifting it into a serious ...

Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

Quantum computing has quietly advanced to a level of maturity and capability that many technologists, and policymakers, still underestimate.

Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on ...
