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 ...

Scientists at the University of Illinois Urbana-Champaign have confirmed the existence of a massless particle, long theorized ...

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 ...

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 ...

Most of the matter in our universe is invisible. We can measure the gravitational pull of this “dark matter” on the orbits of stars and galaxies. We can see the way it bends light around itself and ...

When it comes to understanding the fabric of the universe, most of what scientists think exists is consigned to a dark, murky domain. Ordinary matter, the stuff we can see and touch, accounts for just ...

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 ...

To validate this hypothesis, the researchers cross-verified the results using another model, further confirming the correlation between anomalous particle yields and quark-matter formation.

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.
