Invisible clumps of dark matter may explain three strange cosmic mysteries

Dense dark matter clumps link three strange objects across the universe

A tiny object half a universe away, a scar in a stream of stars circling the Milky Way, and an unusual star cluster in a nearby satellite galaxy may not seem related at first glance. Yet a new study argues they could all trace back to the same kind of invisible structure. This structure is built from a more active version of dark matter than physicists usually assume. That idea matters because dark matter is not a side note in cosmic history. It…

Invisible clumps of dark matter may explain three strange cosmic mysteries

Scientists have long known that most of the matter in the universe is invisible. This hidden material, called dark matter, makes up about 85% of all matter. Even though we cannot see it, we know it exists because of its strong gravitational pull on stars and galaxies. Now, a new study suggests that a special […] The post Invisible clumps of dark matter may explain three strange cosmic mysteries appeared first on Knowridge Science Report.
