Guys! Nice to see physicsforums still seems to be going strong. Lost my interest in physics for a few years but now its back. Been reading about galaxy rotation curves and how MOND, a new stop gap theory, is doing so well compared to the old man dark matter. MOND isn't consistent and has no theorectical foundation, so while it's a great prediction formula, it give no insight into the whats going on. So the fundamental error in our understanding of comso-dynamics is still at large. Now is the time for new theorys. We've got to look at our current model and identify possible bugs. I talk about one candidate bug here... http://csep10.phys.utk.edu/newsgroups/mond/messages/576.html [Broken] You don't need to consider that gravity wave bit. Just consider the central questions and points: Why do we insist we have infinite space in our model? There is no proof space is infinite. Most of the gravity potential in the current infinite space model is lost to the infinity of space. Finite space redistributes onto the universe force otherwise lost in infinite space theory. No energy is lost. Observations show there is a large amount of gravity force unacounted for in the classical, infinite space, model. This one simple change of a parameter in our model is a possible solution. change infinite to finite.
