We consider a vacuum to be the lowest energy state of the Universe. But it's possible that there's an even lower-energy, more ...

Addressing a controversy first raised around 1910, two physicists have performed experiments with the aid of an engineer that validate anew the special theory of relativity’s limitations on the speed ...

For years, one tiny mismatch in particle physics carried outsized hopes. The muon, a heavier and short-lived cousin of the ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

New home: the Muon g-2 ring sits in its detector hall at Fermilab, where it studies precession of muons. (Courtesy: Reidar Hahn/Fermilab) A long-standing discrepancy between the predicted and measured ...

A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum physics. The findings ...
