http://www.truelightoflife.com vxyx2z http://www.insight.spruz.com __ What is gravity? Apart from being the weakest force in the known universe... What exactly do we know about what gravity is? How does gravity make things combined together? How does gravity form planets/stars, etc... I understand the basic concept of gravity.. but I dont understand why things have it... does everything have gravity? do we have gravity? but we are so tiny that it is unmeasurable? or is it just things like stars, planets, and other giant physical objects? the most accurate model we have of gravity is General Relativity which says gravity is embodied by the shape of space time----"gravity is geometry". The main equation is the 1916 so-called Einstein equation which says curvature = (8pi G/c4) energy density
