Two kilometres underground near Sudbury, Ont. , a machine has reached a temperature so low it barely seems real.

Researchers have, for the first time, described the properties of one-dimensional anyons and outlined how these particles can be observed using existing experimental setups.

Dark matter may consist of two particles, explaining why only the Milky Way shows a strange gamma-ray signal while smaller ...

If there weren’t any planets, stars, comets, asteroids, or other cosmic debris flying around, there would be merely the ...

Add Yahoo as a preferred source to see more of our stories on Google. If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or ...

Heavy particles as probes Heavy quarks are like tiny sensors. Being so massive, they are produced just after the initial nuclear collision and move more slowly, thus interacting differently with the ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

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 ...

Dark matter has been thought to be cold and collisionless, meaning its particles don't interact with each other. The new study, however, challenges this assumption.

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 ...
