"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 ...

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

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion of the universe.

Scientists at Fermilab’s MicroBooNE experiment have ruled out the existence of the elusive sterile neutrino, a particle ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

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 ...

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 ...

String theory attempts to unify all forces and particles in the universe using vibrating strings. It aims to explain the Standard Model of particle physics, which is incomplete. String theory predicts ...

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.
