The universe should be a predictably symmetrical place, according to a cornerstone of Einstein's theory of special relativity, known as Lorentz symmetry. This principle states that any scientist should observe the same laws ...

One of the greatest mysteries in astrophysics these days is a tiny subatomic particle called a neutrino, so small that it passes through matter—the atmosphere, our bodies, the very Earth—without detection.

High-energy neutrinos are extremely rare particles that have so far proved very difficult to detect. Fluxes of these rare particles were first detected by the IceCube Collaboration back in 2013.
The international Daya Bay Collaboration has announced new results about the transformations of neutrinos - elusive, ghostlike particles that carry invaluable clues about the makeup of the early universe. The latest findings ...
