Researchers have built an ultra-sensitive sensor capable of detecting unimaginably small amounts of energy — below one zeptojoule. The breakthrough relies on fragile superconducting materials that ...

The universe may have its own version of Heisenberg's uncertainty principle, and that might be enough to explain dark energy without invoking any new physics at all.

CERN’s Super Proton Synchrotron has a resonant “ghost.” Using mathematics, physicists measured and modeled how these resonant lines intersect. Modeling a 3D shape over time requires a 4D system of ...

A single subatomic particle from deep space had the same energy as a baseball pitch, and scientists still don’t know how it got here ...
