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

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. When you purchase through links on our site, we may earn an ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

Inside the Large Hadron Collider, protons slam together at nearly the speed of light, creating a brief fireball of quarks and ...

If dark matter is made from "dark" versions of the basic building blocks of ordinary matter, the world's largest particle accelerator should be able to pin it down, a new study suggests. When you ...

Two recent studies by Professor Stefano Profumo at the University of California, Santa Cruz, propose theories that attempt to answer one of the most fundamental open questions in modern physics: What ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

Physicists have spent decades chasing two grand technological dreams: harnessing fusion power and uncovering the nature of ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

The Large Hadron Collider began smashing atoms together in 2009 and continues to throw up surprising insights into the fundamental building blocks of the universe. It’s via evidence from particle ...

A proposed funding program for small- and medium-scale projects reveals insights into the science, logistical challenges, and future of particle physics research. Particle physicists have a reputation ...
