Deep underground in southern China, there is a 20,000-ton tank of liquid that can detect neutrinos. Named JUNO, the ...

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 ...

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 ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, ...

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 ...

A few days ago, I spotted a strange title on a physics paper, claiming to have produced negative mass. I gave it a read. No they didn’t, I thought to myself. I will not cover this interesting but ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in ...

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 ...

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 ...
