Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

While most of us have a limited understanding of physics, we have an idea of what “critical mass” means. But just in case: when you reach a sufficient and/or necessary level of something to effect ...

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 ...

Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests that the higher dimensional structure of spacetime could be the actual ...
