Dark matter may come in multiple particles and weights, similar to the ordinary elements on the periodic table, a new theory suggests. When you purchase through links on our site, we may earn an ...

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 ...

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 ...

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 ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find. When you purchase through links on our site, we may earn ...

The universe may have produced dark matter in the first few minutes of the Big Bang, according to new research. Those particles then got trapped into ultradense pockets. Some of those pockets ...
