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 ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Astronomers found evidence that dark matter and neutrinos may interact, hinting at a "fundamental breakthrough" that challenges our understanding of how the universe evolved.

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 ...

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 ...

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 ...

Ciaran O'Hare scribbles symbols using colored markers across his whiteboard like he's trying to solve a crime—or perhaps ...

In recent years, a curious hypothetical particle called the axion, invented to address challenging problems with the strong nuclear force, has emerged as a leading candidate to explain dark matter.

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. They say the ...
