By combining different kinds of observations, cosmologists have shown that what we see is more easily explained if neutrinos, ...

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 ...

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

"When my student showed me the data I thought she must be wrong," Boston College professor and lead researcher Kenneth Burch told Live Science. "It's not every day you find a new particle sitting on ...

Our best model of particle physics explains only about 5 percent of the universe. The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and ...

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 ...

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

In 1933, astronomer Fritz Zwicky noticed something strange: The universe seemed to have ‘missing mass.’ Something had to account for the space in between cosmic bodies and the gravitational forces ...
