The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions with matter.

Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly ...

An extensive search for a hypothetical particle has turned up empty. The sterile neutrino is a proposed subatomic particle that could even be a candidate for the mysterious dark matter, and although ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion of the universe.

Spencer Axani, assistant professor in the Department of Physics and Astronomy, is the inventor of CosmicWatch, a portable, ...

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works, a prospect that has the field of particle physics both baffled and ...

You can't see, feel, hear, taste or smell them, but tiny particles from space are constantly raining down on us.

Researechers are testing superconducting microwire single-photon detectors (SMSPDs) for use in future particle physics exepriments. The detectors, which were designed and fabricated at JPL and ...

Physicists often find thrifty, ingenious ways to reuse equipment and resources. What do you do with 800 square feet of scintillator from an old physics experiment? Cut it up and give it to high ...

THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...
