Gravity really is a form of electromagnetism It is something like an analogy to a revved up fly wheel but has nothing to do with spinning nor with spherical planetary characteristics . though certainly related, It still follows what Newton discovered where F=MA. MASS IN MOTION explains it all . an object in motion stays in motion as Newton observed unless something comes and interacts with it. Gravity is a form of interaction between objects in motion. but it is just one type of interaction between objects. objects can collide or they can experience gravity. the difference between collisions and gravity is that that momentum is turned inward within the object itself and that is because not all subatomic particles share the same momentum some drag behind. that revs mass up like a fly wheel and causes code generation.
