It took more than 80,000 baryon decays for us to see matter–antimatter asymmetry with this class of particles for the first ...

Dark matter is a confounding concept that teeters on the leading edges of cosmology and physics. We don't know what it is or ...

Why matter dominates over antimatter in our universe has long been a major cosmic mystery to physicists. A new finding by the ...

CERN scientists at the world’s largest particle accelerator have made a unique antimatter breakthrough, which they believe ...

Matter and antimatter should have completely wiped each other out eons ago, leaving the Universe a very empty place.

Perhaps one of the most surprising discoveries of the 20th century was that this ordinary, or baryonic, matter makes up less than 5 percent of the mass of the universe. The rest of the universe ...

Scientists at CERN have made a groundbreaking discovery that deepens our understanding of why the Universe is made of matter ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as ...

Charge-parity violation is thought to explain why there’s more matter than antimatter in the universe. Scientists just spotted it in a new place.

A key difference has been observed in the behaviour of matter and antimatter particles by researchers working at a particle ...

For the first time, physicists have spotted a difference in the way matter and antimatter baryons decay, which could help to ...

Cosmologists believe about 20% of the total matter is made of regular -- or "baryonic" matter -- which includes stars, galaxies, atoms, and life, while about 80% is made of dark matter ...
