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 ...

Most scientists think that dark matter consists of non-baryonic matter. The leading candidates areWIMPs(weakly interacting massive particles), which are thought to be ten to a hundred times the mass of a proton. However, their weak interactions with "normal" matter make them challenging to detect...
Astronomers watching galaxies collide found evidence of nongravitational forces that could suggest dark matter interacts with itself
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 ...

Dark Matter is a necessary ingredient for a complete theory of Nature, which has so far remained elusive in laboratory searches for new particles. Searches at current and future colliders are in principle a promising way to search for electroweak charged dark matter particles, but the sensitivity...
Instead of WIMPS, weakly interacting massive particles, or axions, which are weakly interacting low-mass particles, dark matter may be made of macroscopic objects, anywhere from a few ounces to the size of a good asteroid, and probably as dense as aneutron star, or the nucleus of anatom, ...
supersymmetric parti- cle (LSP) cannot decay even if it is heavier than most (or all) of the standard-model particles.2 An electrically neu- tral and color neutral LSP candidate—such as the lightest neutralino, the gravitino, or the axino—may thus also be a compelling dark-matter ...
