When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely ...

A cloud of helium atoms split, scattered and fell under gravity, yet still behaved as if its parts were linked. That is the ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions.

Ultraprecise clocks are more than scientific curiosities. They play key roles in navigation, communications and international ...

Could this “spooky action at a distance” lead us one step closer to the ever-elusive Unified Theory of Everything?

A ring of 10 to 30 atoms, each inflated to a fragile, oversized state and held in place by laser tweezers, has given ...

A breakthrough in quantum computing achieves 99.91% accuracy using 17,000 pairs of atoms, bringing us closer to a new era in ...

The results are just what theory predicts, but when the theory clashes as strongly with everyday experience as this, confirmation is precious.

A couple of weeks back I posted an answer to a question from a Twitter follower’s child, who asked “How Strong Is Space?” That was fun, so here’s another kid-question answered, this one from my own ...
