Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

A recent study published in Nuclear Physics B examines how hidden dimensions might influence the physical reality that we ...

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 ...

In science, there are thousands of ways to measure the world around us that the average person may never encounter. For example: Pascals to measure pressure, Candles to measure light intensity, and ...

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 ...

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 ...

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 ...

Mass is mass is mass. Physicists have three different definitions of mass, all thought to be equivalent. Measurements of the distance between Earth and the moon confirm that two of those masses are ...
