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, also known as particle colliders or atom smashers, have been responsible for some of the most exciting physics findings over the past century, including the discovery of 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 ...

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 ...

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 ...

To unlock the secrets of dark matter, scientists could turn to supermassive black holes and their ability to act as natural superpowered particle colliders. That's according to new research that found ...

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 ...

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 ...

There is a limit to how big we can build particle colliders on Earth, whether that is because of limited space or limited economics. Since size is equivalent to energy output for particle colliders, ...
