The problem of Schwarzschild dynamics is of fundamental importance in Modern Physics since the Schwarzschild solution is considered the exact one to the Einstein ﬁeld equation and it is directly testable, in theory. It is widely believed that the solution is ﬂawless and successfully passed the observational test (a planetary perihelion advance prediction) what eventually put General Relativity to the rank of the only true relativistic theory of gravitational ﬁeld. In this work, we critically analyze the GR prediction methodology and investigate physical meaningfulness of the solution, particularly, in view of relationship of proper versus coordinate time variables and their connections with a relativistic mass and energy concepts. The overall conclusion is made that the GR dynamic equation for point particle motion from Schwarzschild metric is prone to inner contradictions inherited from the GR physical foundations. In particular, its exterior solution admits superluminal motion. Strictly speaking, it cannot be used for a treatment of observational data. Alternative approach based on Special Relativity Dynamics with a ﬁeld-dependent proper mass concept is presented.
