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 ...

Black holes ruled out as universe's missing dark matter

For one brief shining moment after the 2015 detection of gravitational waves from colliding black holes, astronomers held out hope that the universe's mysterious dark matter might consist of a plenitude of black holes sprinkled ...

Hyper Suprime-Cam survey maps dark matter in the universe

Today, an international group of researchers, including Carnegie Mellon University's Rachel Mandelbaum, released the deepest wide field map of the three-dimensional distribution of matter in the universe ever made and increased ...

A quantum leap toward expanding the search for dark matter

Figuring out how to extend the search for dark matter particles – dark matter describes the stuff that makes up an estimated 85 percent of the total mass of the universe yet so far has only been measured by its gravitational ...

Gravity theory saved from death

An international group of astronomers, including physicists at the University of St Andrews, has revived a previously debunked theory of gravity, arguing that motions within dwarf galaxies would be slower if close to a massive ...
