Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using ...

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 ...

Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect ...

Despite making up most of the matter in the universe, dark matter doesn't interact with light. So how do astronomers know it is there? When you purchase through links on our site, we may earn an ...

Astronomers working with the Hubble Space Telescope have identified a nearly invisible galaxy in the Perseus Cluster that appears to consist almost entirely of dark matter. Designated Candidate Dark ...

A NASA telescope may have detected evidence of dark matter, enabling it to be “‘seen” for the first time. Since dark matter was conceptualized nearly 100 years ago by Swiss astronomer Fritz Zwicky, ...

Now is a surreal time to be a dark matter researcher. Even as research funding is being cut by governments around the world, dark matter remains one of the biggest and most exciting open problems 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 ...

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 ...
