Dark matter has been indirectly detected from astronomical observations. Analysis using Newton’s gravitational theory of the motion of stars, galaxies and galactic clusters, and also analysis using Einstein’s theory of the bending of light around these collections of stars, all indicate that the amount of dark matter (matter that is invisible for our telescopes) is at least 10 times the mass of the visible (star-like) matter in the universe. Presently it seems clear that Dark Matter has the same large-scale distribution as galactic clusters and super-clusters, except that the Dark Matter ‘halos’ extend somewhat beyond the visible galaxy and often overlaps several galaxies. Dark Matter ‘halos’ are usually but not necessarily spherical. The exact shape of galactic Halos is being actively researched. For example, the Milky Way Halo appears to incorporate its satellite galaxies.
