Bold new theories on "mirror worlds" and how dark matter may have formed - from black hole relics to quantum horizons.

Two fresh ideas are giving scientists new ways to think about how the universe’s hidden mass came to be. Together, they paint ...

Physicists detect antihydrogen-4, the heaviest antimatter nucleus ever created, fueling new theories about dark matter and ...

Can galaxies exist without an outer halo of dark matter? But new research flips this question around, investigating whether ...

Researchers from NAOJ, the University of Tokyo, and collaborators analyzed test data from Hyper Suprime-Cam’s commissioning to see how well it could map dark matter using the weak lensing technique.

Based on their higher-resolution mass map, Coe and his collaborators confirm previous results showing that the core of Abell 1689 is much denser in dark matter than expected for a cluster of its ...

The result of mapping this light is the "forest", resembling many small trees. The team says that using hydrogen spectrograms can be used to trace dark matter indirectly, like pouring dye into a ...

Mapping the dark matter All galaxies are made up of stars, gas, dust, and dark matter, which are bound together by gravity.

Dark matter, which makes up about 85% of the total matter in the universe, has been sort of a problematic phenomenon for scientists because it doesn't interact with light — or, if it does, that ...

The first evidence that dark matter existed is traced back to the 1930s, but it became even more clear that some invisible mass was acting on the gravitational forces of the universe in the 1960s ...

When dark matter is clustered around a galaxy, for example, its gravitational tug can deflect light. Because of this we can map the distribution of dark matter in the universe by observing how ...

In this way, the researchers succeeded in mapping out a massive clump of dark matter, with a mass equivalent to that of some 200 trillion suns, that lies roughly 1.4 million light-years from the ...
