At that time, the slabs of rock that carried these present-day continents crawled apart from each other at a rate of a millimeter a year. Dark Matter earned its name because it does not interact at all with the Electromagnetic Force. One of the reasons that dark matter has arisen as a theory is the fact that when we observe certain galaxies, they have much more kinetic energy then the masses in them would suggest, therefore, a separate force must be at play.
