At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of light and cause tiny distortions in space-time. Albert Einstein predicted ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

Infleqtion, a Boulder-based quantum-technology company, said this week that it “will fly the first quantum sensor capable of measuring the Earth's gravitational field and its gradients” as part of ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

Quantum computing technology is complex, getting off the ground and maturing. There is promise of things to come. potentially ...

"We have long treated the Planck scale like a blurry limit," said Kulkarni. "But if you treat space as an information storage medium, geometry dictates a specific packing efficiency. The universe has ...
