We may already have had our first-ever encounter with dark matter, according to researchers who say a mysteriously ...

But the study authors write that their theory is distinct because it can be tested using existing observational data. The extremely low-energy particles they suggest make up dark matter would have ...

A new theory says dark matter acts remarkably similar to subatomic particles known to science since the 1930s. A new theory says dark matter acts remarkably similar to subatomic particles known to ...

other research has suggested dark matter particles only interact with themselves, and not regular matter or photons, which the pion theory would allow. “Dark matter is our mother. Without it ...

Their theory suggests that ... energy into a hot plasma of particles and radiation. Despite accounting for about 25 % of the ...

Loeb said now the question is if scientists can distinguish between particle dark matter and this modified theory of gravity to come to a conclusion on what's going on with dark matter.

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 ...

This groundbreaking discovery was made by monitoring charm mesons, which are subatomic particles that contain a quark (elementary particles, and fundamental block of matter) and an antiquark.

If this idea is validated, it’s an inexpensive and low-lift way to confirm or rule out one theory ... Sutter explained that these maybe-particles of dark matter are “millions of times lighter ...

Because only the heavier particles survived, this theory could guide new scientific endeavors to track down and identify what dark matter is made of by ruling out lighter candidate particles like ...

They report that their theory can be tested using existing data -- these dark matter particles would have a unique signature on the radiation that fills all of the universe known as the Cosmic ...
