At a fundamental level, what is our Universe made of? This question has driven physics forward for centuries. Even with all the advances we've made, we still don't know it all. While the Large ...

The standard model has no puzzles or problems, and incorporates at a fundamental level everything from condensed-matter physics to astrophysics. It achieves the goals of four centuries of physics.

Frank Close tells us about the history of particle physics, and what it means that charge in our universe's matter is so closely balanced.

A U.S. research lab has announced one of the most precise measurements ever of how a subatomic particle behaves, teeing up a showdown that could either vindicate one of science's most powerful ...
