Dark Matter Mechanics seeks to supplement the descriptions of physical behaviors in Physics and Theoretical Physics by determining what causes the behaviors being described, an attribute that is totally missing from models and mathematics of these sciences where the vacuum is presumed empty and devoid of matter. The possibility of the Dark Matter discovered by cosmologists and astrophysicists comprises the vacuum may revolutionize these sciences with mechanical theory. This material applies principles of mechanical causation to determine how to mimic these mathematical theories of behavior.
