UPDATE: I think the label "Relativistic Rocket Science" is not a good one. The term in question is the result of the product rule of calculus. There is only one velocity. In contrast, rockets always involve at least two velocities, that of the rocket and the propellant. In any future studies, I will refer to this as the product rule force.

This is a dramatic reading of "Relativistic Rocket Science for Astrophysics" by the Stand-Up Physicist available on Science20.com (http://bit.ly/GEMblog). Three problems with Newtonian gravity are discussed: the velocities seen in galaxies, the big bang, and the current acceleration. Dark matter, inflation, and dark energy are hypotheses that try to explain each issue using new forms of matter, as yet identified. 

Modification of Newtonian Dynamics, MOND, is a technical speculation for the velocities seen in galaxies. It has 1 free parameter. It is consistent with what is seen for disk galaxies and gas dominant ones too. The proposal is wrong because it is not consistent with data from the bullet galaxy.

A new effect for gravity is proposed: the relativistic rocket science term. This allows gravity to work in a new way in a new direction. The effect of gravity for systems moving at a constant velocity is to determine where mass goes. This has a chance to solve all three problems. At this time, the math is beyond my reach.
