Neutrons escaping to a parallel world?

In a paper recently published in European Physical Journal C, researchers hypothesised the existence of mirror particles to explain the anomalous loss of neutrons observed experimentally. The existence of such mirror matter ...

A new era in the quest for dark matter

Since the 1970s, astronomers and physicists have been gathering evidence for the presence in the universe of dark matter: a mysterious substance that manifests itself through its gravitational pull. However, despite much ...

NASA's Fermi mission expands its search for dark matter

Dark matter, the mysterious substance that constitutes most of the material universe, remains as elusive as ever. Although experiments on the ground and in space have yet to find a trace of dark matter, the results are helping ...

New Limits on the Origin of Dark Matter

(PhysOrg.com) -- Determining the identity of dark matter, the mysterious stuff thought to make up the vast majority of matter in the universe, is one of the most fundamental challenges facing modern physics. Through theory ...

Placing another piece in the dark matter puzzle

Very little is known about the exact nature of dark matter. Currently, some of the most promising dark matter candidates are extremely light bosonic particles such as axions, axion-like particles or even dark photons. "These ...

New detectors allow search for lightweight dark matter particles

The Earth, planets, stars, and galaxies form only the visible portion of the matter in the universe. Greater by far is the share accounted for by invisible "dark matter". Scientists have searched for the particles of dark ...
