Dark matter is more than five times as abundant as all the visible matter in the universe. So why can't we see any of it?

And he called it dark matter.” Zwicky’s discovery was just the first example of apparently missing mass. In the late 1970s, astronomers Vera Rubin and Kent Ford were observing our neighboring ...

Dark matter makes up a large portion of the universe, but we've never seen it. Here's what we know, what it might be, and why it could change everything. More than 80% of the universe's matter is ...

The study seeks to explain the presence of dark matter using a WED model. The scientists studied fermion masses, which they ...

"It's all about mindset in science, where a null result can be as impactful as a positive result." The quest to find dark matter is a curious one. It is, quite literally, a shot in the dark.

There may be many different kinds of dark matter particles, all interacting in a variety of ways. So, for example, instead of electrons interacting via photons, there might be dark electrons ...

For example, an extraordinarily small lambda ... “Maybe this is the dark matter?” Vafa mused. The gravitons they had concocted were, after all, weakly interacting yet capable of mustering ...

First and perhaps most perplexingly, researchers remain unsure about what exactly dark matter is. Originally, some scientists ...

Even without such interactions with ordinary matter, dark matter's self-interactions might have observable consequences. For example, the internal structure of galaxies at small scales will be ...

For example, some scientists suggested dark matter might be ordinary matter – a dead star, or something else that, once cool, is hard to detect. Or, perhaps, it is bound inside black holes ...

Never has this been the case more than with dark matter. Though it's far more abundant than the matter we can see and feel, dark matter as we know it is virtually immune to observation ...

Dark matter could also explain certain optical illusions that astronomers see in the deep universe. For example, pictures of galaxies that include strange rings and arcs of light could be ...
