Buried deep below the American Midwest, a new kind of observatory is taking shape that aims to watch some of the most elusive particles in the universe as they stream straight through Earth. The Deep ...

A Los Alamos collaboration has replicated an important but largely forgotten physics experiment: the first deuterium-tritium (DT) fusion observation. As described in the article published in Physical ...

The ALICE Collaboration is a winner of the 2025 Gizmodo Science Fair for transforming lead into gold for a fraction of a second and exposing the strange physics that goes on inside the Large Hadron ...

The United States should fund proposed projects to dramatically scale up its efforts in five areas of high-energy physics, an influential panel of scientists has concluded. Topping the ranking is 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 ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

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 ...

A breakthrough quantum physics experiment has revealed a startling result. Scientists measured “negative time” as photons ...

In a first, scientists have shown that they can send light through “slits in time” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a ...
