Scientists do know that dark matter forms massive halos that surround galaxies.
Navarro and collaborators employed numerical models to show that these halos all look the same from galaxy to galaxy. Unlike other structures in the universe, the halos take an identical shape and don't depend on their particular mass or other parameters that typically dictate how structures in the universe form and evolve. The findings have been backed up by direct observational tests.
