There are three types of neutrino — electron, muon and tau — and the type is set when a neutrino is generated or detected. For example, in a nuclear process called β decay, an unstable nucleus ...

Humble neutrinos — electrically neutral particles that glide through the universe, unaffected by the forces of nature — have helped to shape the cosmos. They play a role in nuclear fusion, radioactive ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the ...

Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact with other matter via the weak force or gravity. While these particles have ...

Years of conflicting neutrino measurements have led physicists to propose a “dark sector” of invisible particles — one that could simultaneously explain dark matter, the puzzling expansion of the ...

ON FEBRUARY 13th 2023 an object with extraterrestrial origins went screaming through the Mediterranean Sea off the Sicilian coast. A single, super-energetic subatomic particle left a sparkling trail ...

Physicists in Italy and China have for the first time observed glimmers of the ‘neutrino fog’, signals from neutrinos that mimic those expected to be produced by dark matter. Every second, trillions ...
