="Henry Baker" <hbaker1@pipeline.com> ... Could any such gravitational lensing explain the rotational velocity of galaxies -- perhaps by focussing the effect from the opposite side of the galaxy using the black hole at the center as a lens?
I've heard that the main reason for ascribing "stuffiness" to explain the observations, rather than buggy equations, is that they are irregular spatially (eg distorted motions within globular clusters) rather than more homogeneous effects liked you'd see from, say, neglecting terms that only become significant at galactic scales. I imagine a similar argument applies to large scale structures such as central black holes as being sufficient to fully explain all the detailed discombobulations.
