Abstract
There have been no shortage of theories to describe Dark Matter. Most of the current theories have one thing in common, either they propose new, yet to be discovered, particles or modifications to the Standard Model. So far, all attempts to prove that Dark Matter exists have failed. With the lack of supporting experimental results for any existing Dark Matter theories, it is time to examine other solutions that might explain Dark Matter without requiring any new particles to be detected. A different solution to the galaxy rotation problem would be to assume there is some external force pressing in on the galaxies holding them together. This research shows how external forces on the galaxies can duplicate the galaxy rotation curves that have been observed, without any Dark Matter. It also explains the acceleration constant a0 from the Modified Newtonian Dynamics (MOND) theory. The results show that a model using an external galactic force is a valid approach to explain Dark Matter.
