A Hidden World of Complex Dark Matter Could Be Uncovered

> Cosmologists believe that some unseen kind of matter—dark
> matter—surrounds and permeates Andromeda and other galaxies, adding
> the necessary gravitational force to keep them spinning as observed.
> Dark matter, which appears to contribute about 25 percent of the
> universe's mass, would also explain other aspects of the cosmos,
> including the exceedingly fast motion of galaxies within clusters of
> galaxies, the distribution of matter arising when two clusters
> collide and the observation of gravitational lensing—the bending of
> light by gravity—of distant galaxies.
