Scientists at CERN’s Large Hadron Collider (LHC) have for the first time observed a fundamental asymmetry in the behavior of baryons, the particles that form the bulk of all visible matter. The ...

Physicists have shown that, like everything else experiencing gravity, antimatter falls downwards when dropped. This outcome is not surprising — a difference in the gravitational behaviour of matter ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...
