Physicists have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

The standard model of particle physics is beginning to show cracks. A fundamental particle called the muon has been caught behaving strangely, and new experimental results from Fermilab in Illinois ...

In their search for more flavors of Higgs bosons, a team of researchers at CERN stumbled across what could be evidence of the smallest matter-antimatter particle ever. The hypoethical particle, known ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. One of the biggest questions in particle physics is whether the ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Extremely massive fundamental particles could exist, but they would seriously mess with our understanding of quantum mechanics. Fundamental particles are objects that are so small, they have no deeper ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

This newly-discovered particle could account for dark matter. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Researchers have discovered a new ...

Far beneath the Antarctic ice sheet, scientists are mapping a landscape that looks less like a frozen desert and more like an ...
