Dark matter can't be too heavy or it might break our best model of the universe, new research suggests.

We have an abundance of evidence that something fishy is happening in the universe. Stars orbit within galaxies far too quickly. Galaxies move around inside clusters much too fast. Structures grow and evolve too rapidly. If we count only the matter we can see, there simply isn't enough gravity to explain all of these behaviors.

The vast majority of cosmologists believe all of these phenomena can be explained through the presence of dark matter, a hypothetical form of matter that is massive, electrically neutral and hardly, if ever, interacts with normal matter. This dark matter makes up most of the mass in the universe, far outweighing the amount of luminous matter.@centyone
