This theory predicts that the inertia of stationary objects will increase when massive objects are nearby. That effect is related to another that applies to objects with nonzero angular or linear momentum. When objects are eclipsed by particularly massive objects multiple distorted images appear. In addition to predicting the Lense-Thirring effect 
This theory predicts that the inertia of stationary objects will increase when massive objects are nearby. That effect is related to another that applies to objects with nonzero angular or linear momentum. When objects are eclipsed by particularly massive objects multiple distorted images appear. In addition to predicting the Lense-Thirring effect and gravitational lensing, one of its axioms is that a reference frame experiencing gravitational effects appears to be accelerating, called the equivalence principle. FTP, name this theory of gravity developed by Einstein.
