Neutrinos are weird. But all the big unsolved problems in physics are somehow connected to one unsolved mystery: Why do ...

After a decade-long analysis, a collaboration of physicists has made the most precise measurement of the mass of a key particle – and it may unravel physics as we know it. The new measurement differs ...

Jackson Ryan was CNET's science editor, and a multiple award-winning one at that. Earlier, he'd been a scientist, but he realized he wasn't very happy sitting at a lab bench all day. Science writing, ...

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

Physicists have taken one small-but-consequential step toward measuring the mass of an elusive "ghost particle" called a neutrino — an achievement that could poke a significant hole in the Standard ...

The New Year may also be a year of discoveries for physicists plumbing the deepest mysteries of matter. Since 2013, when scientists at the Large Hadron Collider (LHC) confirmed they had discovered the ...

The W boson, one of the tiniest, most elementary particles in the known universe is causing a big ruckus in the field of particle physics. According to the Standard Model, W bosons (together with ...

An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...

There’s a lot more to the story of the Higgs boson than just one man named Higgs. Despite the appeal of the “lone genius” narrative, it’s rare that a discovery can be attributed solely to the work of ...

Negative mass is a hypothetical concept that says matter can exist with a mass opposite to normal matter. Instead of having a positive weight—1kg, for example—negative mass would weigh minus 1kg. This ...
