Visible matter, also called baryonic matter, consists of baryons — an overarching name for subatomic particles such asprotons, neutrons and electrons. Scientists only speculate what dark matter is made of. It could be composed of baryons but it could also be non-baryonic, which means consisting...

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.
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. ...
What is dark matter? A. Matter that interacts with light. B. Matter that does not interact with light but can be detected by its gravitational effects on visible matter. C. A mysterious force that causes the expansion of the universe to accelerate. D. Regions of space where the ...

What is Dark Matter? (Video)Christopher Mims
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...
What Is Dark Matter? A computer simulation shows dark matter is distributed in a clumpy but organized manner. In the figure, high density regions appear bright whereas dark regions are nearly, but not completely, empty.(Image credit: Institute for the Physics and Mathematics of the Universe)...
