The Savoy region of France is best known for its fir-lined ski slopes and picturesque Alpine villages. Less known is the fact that, deep beneath some of these slopes, scientists are investigating one of the greatest mysteries in physics: the origin of matter.
A hint that neutrinos behave differently than antineutrinos suggests an answer to one the biggest questions in physics.

The Deep Underground Neutrino Experiment (DUNE) could help unravel the mysteries of antimatter and complete scientists’ next model of the universe.

The question is more complicated than it seems.
Welcome to ‘New Physics’.
In a new paper accepted by the journal Astroparticle Physics, Robert Ehrlich, a recently retired physicist from George Mason University, claims that the neutrino is very likely a tachyon or faster-than-light particle. There have been many such claims, the last being in 2011 when the “OPERA” experiment measured the speed of neutrinos and claimed they travelled a tiny amount faster than light. However, when their speed was measured again the original result was found to be in error – the result of a loose cable no less.
Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at the University of Massachusetts Amherst report in the current issue of Nature that for the first time they have directly detected neutrinos created by the “keystone” proton-proton (pp) fusion process going on at the sun’s core.
Dark matter emits no light, and cannot be directly observed, but scientists think that it and dark energy make up most of the mass of the universe.
