Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

A cosmological simulation study by researchers from the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has systematically revealed, for the first time, how the interaction ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells ...

Add Yahoo as a preferred source to see more of our stories on Google. A bright band of diffuse gamma ray glow along the map's center, which marks the central plane of the Milky Way galaxy, is seen in ...

Scientists have long been puzzled by dark matter, an elusive substance that makes up about 27% of the universe. Recent breakthroughs in research are shedding light on its mysterious nature, ...

Nov. 26 (UPI) --More than 100 years after its existence was predicted, scientists report that they have, for the first time, seen dark matter. Scientists have been able to indirectly observe dark ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

A puzzling ultraviolet light seen across the Milky Way could come from the destruction of nuggets of dark matter, the mysterious stuff that makes up around a quarter of the matter and energy in the ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely interact with the rest of the universe via gravity and to serve as the ...
