I've heard of a place where measurement of g-lensing around a pair of 
colliding galaxies shows that normal matter was slowed by the collision 
(gas friction) but dark matter was not; that is, the mass whose gravity 
affects the light of further galaxies is not only *more* than the 
visible matter, it's in different places.
