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

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting ...

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 ...

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 ...

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 ...

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 ...

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

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 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 ...

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 ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. When you purchase through links on our site, we may ...

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.
