If dark matter is made from "dark" versions of the basic building blocks of ordinary matter, the world's largest particle accelerator should be able to pin it down, a new study suggests. When you ...

Because we haven't found anything yet, we've started to wonder if dark matter might be lighter or heavier than we thought. When you purchase through links on our site, we may earn an affiliate ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines ...

As the youthful universe congealed under the pull of gravity, matter knotted itself into galaxies, galaxy clusters and filaments, weaving a dazzlingly intricate cosmic web. This web’s structure is ...

Physicists are quietly rolling out a new generation of simulation codes that promise to do more than crunch numbers. By ...

Faint hydrogen signals from the cosmic Dark Ages may soon help determine the mass of dark matter particles. Simulations suggest future Moon-based observatories could distinguish between warm and cold ...

A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark matter. A mysterious phenomenon at the centre of our galaxy could be the result of a different type ...

The neutrino “fog” is beginning to materialize. Lightweight subatomic particles called neutrinos have begun elbowing their way into the data of experiments not designed to spot them. Two experiments, ...

Scientists have long suspected that a see-through substance known as dark matter suffuses the cosmos, keeping the fabric of our universe from tearing. But what exactly dark matter is made of remains a ...
