Science isn’t always serious. Sometimes researchers ask questions that seem silly at first, like why toast lands butter-side down or how ducks stay dry. But these quirky experiments often lead to ...

A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the atoms themselves are the ones saying so.

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the ...

Neutrinos are some of nature’s most elusive particles. One hundred trillion fly through your body every second, but each one has only a tiny chance of jostling one of your atoms, a consequence of the ...

Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we know them.
