Despite decades of study, scientists still don't know exactly what dark matter is made of. They do know it's not made of ordinary atoms — the same kind of matter that makes up stars, planets, and people. That kind of matter is called "baryonic," and dark matter appears to be "non...

It may also be responsible for the Milky Way's unusual shape. The interaction involves two smaller galaxies near the Milky Way, called Magellanic Clouds,moving through a large amount of dark matter. Without the existence of the dark matter,the Magellanic Clouds wouldn't have enough mass to ...
The meaning of DARK MATTER is nonluminous matter not yet directly detected by astronomers that is hypothesized to exist to account for various observed gravitational effects.
Self-interacting dark matter with dark forces and dark photons may not be as simple as the single-particle explanation but it is just as reasonable an idea, Weiner says. “The strongest motivation for considering dark matter to have its own interactions is simply that when we ...
As these tendrils stretched across the universe, their distribution may have directed where regular matter eventually collected, helping to shape where and how galaxies formed. Not only is dark matter invisible, but the effects of its gravitational potential are so physically sprawling that they're ...
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. Comments (0) When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The...
Dark matter may not be made of tiny particles as most scientists believe, but instead may consist of large chunks of strange matter anywhere from the size of an apple to an asteroid, researchers said. Currently one of the greatest mysteries in science, the invisible substance calleddark matter...
The concern that dark matter may simply be undetectable is a genuine one. “The Universe could be unkind,” says Fiorucci. “It may well be that dark matter is either very light or very heavy, or its density is too low where the Earth is.” It might be hidden by noise or overlooked...
