Using External Galactic Forces as an Alternative to Dark Matter

Authors: Scott S Neal

It has been over 30 years since the first Cold Dark Matter (CDM) model was proposed as a way of describing Dark Matter, but as yet, there have been no experimental results that support CDM. CDM depends on the discovery of new non-baryonic particles not defined in the Standard Model as the source of the needed mass. Recently, final results from the Large Underground Xenon (LUX) dark matter experiment, have failed to find any traces of these non-baryonic particles, and the Large Hadron Collider (LHC) has not detected any strong evidence of supersymmetry particles. With the lack of supporting experimental results for CDM or supersymmetry, it is time to examine other solutions that might explain Dark Matter without requiring any new particles to be detected. The current concept of Dark Matter assumes the undiscovered particles add an additional gravitational mass to the galaxy. Another 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 gravitational forces on the galaxies can duplicate the galaxy rotation curves that have been observed, without any Dark Matter. It also offers an explanation for the acceleration constant a_0, that results from the modified Newtonian dynamics (MOND) theory of galaxy dynamics. The results show that a model using an external galactic force is a valid approach to explain the effect known as Dark Matter.
