Expanding Universe & Gravitational Repulsion
Before invoking Dark Matter, I think we should consider the possibility of another fundamental force. If we look at magnetism. It is very strong at close distances, but its force falls off very rapidly. Gravity, on the other hand, is comparatively weak force, yet it diminishes very slowly with distance. Following this trend, we can imagine a third, far weaker force that makes every piece of matter repel every other piece of matter. Although it is a far weaker force than gravity, it becomes more important at very great distances because it diminishes even slower than gravity.
Even ordinary gravity overwhelms this force until one is considering truly great distances. At some point, gravity has become even smaller that this weaker antigravity force because the weaker force needs a great deal more distance to weaken by the same amount, just as , at some distance, the gravitational attraction between two magnets becomes stronger than the magnetic attraction between them because of their different rates of diminution.
