The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

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 ...

Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible field, but from the hidden geometry of space itself. Instead of treating extra ...

A new measurement finds the universe's teensiest particles weigh no more than one-millionth the mass of an electron. Reading time 2 minutes Physicists have placed a new limit on how big the elusive ...

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

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 discovery of the Higgs boson provided insight into what gives elementary particles mass. The Higgs boson, a fundamental particle predicted by theorist Peter Higgs, is key to understanding why ...

(Nanowerk News) Physicists in Konstanz (Germany) have discovered a way to imprint a previously unseen geometrical form of chirality onto electrons. The electrons are shaped into chiral coils of mass ...
