Some excellent results for the modification of Newton's simple assumptions on gravity have been achieved just recently: MOND predicts dwarf galaxy feature prior to observations: Also indicates gravity fields vary where dark matter presumes uniformity I would like to make the speculation that dwarf galaxies nearer the host, Andromeda, are also closer to it's plane of rotation. Isn't it quite possible that there is an additional force of attraction on the plane of rotation of a galaxy which would explain these results? It would also have imminent potential for explaining the spiral galaxy rotation curve enigma. Aren't the best ideas often the simplest? Please Register or Log in to view the hidden image!
