If these knots had a slight bias toward matter over antimatter, their unraveling could help explain the matter-antimatter ...

Ah, dark matter. Creator of the universe, sculptor of galaxies, great brewer of coffee (probably). There seems to be nothing it can’t do, or isn’t responsible for, but there’s just one problem: Where ...

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate ...

Deep in the heart of our galaxy, there is a faint but powerful glow that has puzzled scientists for more than a decade.

New simulations tilt the scales for competing theories about excess gamma ray light at the center of the galaxy ...

A study by Dartmouth researchers proposes a new theory about the origin of dark matter, the mysterious and invisible substance thought to give the universe its shape and structure. The researchers ...

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole. This proposal, which endows dark matter particles with a ...

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 ...

A gamma ray glow at our galaxy’s center has puzzled scientists for almost two decades. New computer simulations back the ...

The search narrows for a mysterious form of matter predicted from Einstein's theory of special relativity. After more than a decade of looking, scientists at the world's largest particle collider ...

The Standard Model of particles and interactions is remarkably successful for a theory everyone knows is missing big pieces. It accounts for the everyday stuff we know like protons, neutrons, ...

Dark matter makes up 27 percent of the universe’s total mass and energy — nearly five times more than “normal” matter that comprises planets and stars. True to its name, dark matter is hard to ...
