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

A phase change in the early universe and particles called HYPERs could make dark matter detectable in future experiments. When you purchase through links on our site, we may earn an affiliate ...

Dark matter could be made of particles that each weigh almost as much as a human cell and are nearly dense enough to become miniature black holes, new research suggests. While dark matter is thought ...

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

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 ...

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.

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 ...

Scientists at CERN’s Large Hadron Collider (LHC) have for the first time observed a fundamental asymmetry in the behavior of baryons, the particles that form the bulk of all visible matter. The ...

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 ...

The universe has cooked up all sorts of bizarre and beautiful forms of matter, from blazing stars to purring cats, out of just three basic ingredients. Electrons and two types of quarks, dubbed “up” ...
