LIVERMORE, Calif. – Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as ...

How many kinds of elementary particles should I say there are? In experiments at the Large Hadron Collider, physicists smash ...

A University of Melbourne researcher has placed the strongest constraints yet on certain rare decays of subatomic particles, ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles of matter and antimatter decay. By Kenneth Chang Understanding why matter ...

Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key ...

What is dark matter? Even for astrophysicists, it's a question that remains unanswered. These invisible particles make up most of the matter in the universe and about a quarter of the universe as a ...

Dark matter is invisible, because it neither absorbs or emits light like other matter in the universe does. We can only see its effects, because it bends space-time in a similar way to gravity. Quoted ...

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, ...
