Deep beneath the border of France and Switzerland is the most massive, most ambitious experiment ever undertaken by humanity. The Large Hadron Collider (LHC) is a particle accelerator that uses a ...

China's ambitious new particle accelerator was meant to pick up where the Large Hadron Collider left off, but the project was ...

Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of ...

Particle accelerators (often referred to as “atom smashers”) use strong electric fields to push streams of subatomic particles—usually protons or electrons—to tremendous speeds. Accelerators by the ...

Twenty-five feet below ground, SLAC National Accelerator Laboratory scientist Spencer Gessner opens a large metal picnic basket. This is not your typical picnic basket filled with cheese, bread and ...

Physicists are learning to carve laser beams into intricate shapes that can grab hold of electrons and push them with a ...

The European Space Agency’s (ESA) Cluster satellites have discovered that cosmic particle accelerators are more efficient than previously thought. The discovery has revealed the initial stages of ...

The world’s biggest particle accelerator, the Large Hadron Collider (LHC), sits in a circular tunnel about one hundred meters beneath the Swiss French border near Geneva. It is huge—some 17 kilometers ...

A study provides crucial clues about how cosmic objects send accelerated particles through space. Jets coming from quasars and supernovae can send dangerous cosmic rays that hit Earth. For the first ...

Physicists are increasingly entertaining a radical possibility: our familiar universe of three dimensions of space and one of ...
