Response To T. Larsson
I would like to point out to the “often wrong, but never in doubt” T. Larsson that I am not a dark matter denier, nor would I advocate doing theoretical violence to the elegant and oft-vindicated General Relativity. Discrete Scale Relativity proposes that General Relativity dominates interactions at all fundamental cosmological Scales (i.e., …Subquantum, Atomic, Stellar, Galactic, Metagalactic, …) in an infinite and eternal self-similar (fractal) cosmos. EM interactions play a very important, but secondary role.
One must understand a theory, or in this case a whole paradigm, before one can scientifically evaluate it.
