Are quantum particles polygamous? New experiments suggest some of them abandon long-standing partnerships when ...

Dark matter is believed to make up most of the matter in the universe, yet it has never been directly detected. One theory ...

Deep inside what we perceive as solid matter, the landscape is anything but stationary. The interior of the building blocks of the atom's nucleus -- particles called hadrons that most of us would ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

A new theory suggests fusion reactors could help scientists search for axions, mysterious particles that may explain dark ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

Scientists have discovered a new state of matter that isn't a solid, liquid, or gas. Researchers call this new type of material a 'corralled supercooled liquid'. Atoms in a liquid are normally like ...

Dark matter may be a quantum mechanical wave that literally holds galaxies together. Quantum mechanics is our best theory of the fundamental nature of reality, but it's usually only distinguishable ...

The "final parsec problem" describes the difficulty in explaining how supermassive black holes lose sufficient orbital energy to merge when separated by distances around one parsec, where ...

Dark matter is an elusive type of matter that does not emit, reflect or absorb light, yet is estimated to account for most of the universe's mass. Over the past decades, many physicists worldwide have ...
