Dark matter does not seem to interact with the universal electromagnetic field in the slightest—that is, it does not absorb or emit light of any kind. Dark matter seems only to interact with the universe as we can observe it through a single physical force: gravity. So, in the case of...
Dark matter is a mysterious non-luminous substance making up the vast majority of matter in the universe. Though experts have observed the gravitational effects of dark matter for decades, scientists remain baffled as to its true nature.
Since we don't know what dark matter is, the answer is: for every possible candidate for the dark matter there is a different strategy to search for it. People build giant detectors deep underground (to get away from all the other particles streaming through the environment around us) and ...
Back in 1933, most of the universe went missing. According to many astronomers, it’s still missing. We’re talking about dark matter which can’t be seen. So, how do we know that dark matter exists? Bob Berman explains what dark matter is—and isn’t. ...

Scientists have several candidates for the types of particles that make up dark matter. One possibility is that dark matter is made of WIMPs (weakly interacting massive particles) that would have 1 to 1,000 times more mass than a proton. Another candidate is the axion, a particle ten-trillio...
