No I don't accept the dark matter theory. The reason being is that we are over looking some very basic observation. Motion is that observation. By all rights I believe it should be elevated to the status of a basic force. All motion appears to be time oriented. One way. Combine motion with the weak force and the electromagnetic forces come into play. Combine motion with the strong force and the mechanical forces come into play. Combining the weak force and the strong force without the presence of the motion force is also a combination. There appears to be plenty to work with right here without fabricating something that by all rights is just pure fiction.
