Some of the most fundamental questions about our universe are also the most difficult to answer. Questions like what gives matter its mass, what is the invisible 96 percent of the universe made of, ...

Particle accelerators produce and accelerate beams of charged particles, such as electrons, protons and ions, of atomic and sub-atomic size. They are used not only in fundamental research for an ...

In 2023, Earth was struck by a subatomic particle so energetic that, on paper, it should not exist. The neutrino, calculated ...

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 ...

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 ...

Black holes are powerful engines of pure gravity, capable of pulling on objects so intensely that they can't possibly escape. When those objects near the event horizon, they're accelerated to ...

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 ...

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.

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 ...

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 ...

Physics researchers are looking to the smallest of particles to try to answer some big questions about the universe, from why matter has mass, to whether string theory can truly explain the way the ...
