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 ...

Because we haven't found anything yet, we've started to wonder if dark matter might be lighter or heavier than we thought. When you purchase through links on our site, we may earn an affiliate ...

An analysis of several experiments aimed at detecting the mysterious neutrino has identified a hint of a crack in the ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

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

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 ...

Searches for dark matter particles have come up empty so far, driving theorists to get more creative with their ideas.

Neutrinos are one of the most elusive and omnipresent particles in the universe. Their strange properties may explain why the amounts of matter and antimatter in our universe aren’t equal, as most ...

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 ...

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.

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 ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...
