Observations of extremely rare subatomic particle actions have allowed scientists to put one of the most stringent limits yet on the reigning theory of particle physics. Physicists at the world's ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

Imagine trying to prove that 1+1=2, but when you do the calculations, it turns out that the result is off by 0.1%. That scenario is similar to the riddle that’s facing physicists worldwide as they try ...

NPR's Ayesha Rascoe speaks to Esra Barlas Yücel, a researcher at University of Illinois at Urbana-Champaign, about Fermilab's most precise measurements of the muon particle's magnetic wobble. It's ...

WASHINGTON (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their ...

GENEVA -- One of the very pillars of physics and Einstein's theory of relativity -- that nothing can go faster than the speed of light -- was rocked Thursday by new findings from one of the world's ...

After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

Jefferson Lab’s search for smaller-than-an-atom bits of matter that nobody has spotted but that theory says exist is getting some help with crunching through the reams of data its GlueX detector has ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...
