ABSTRACT
It is shown that a central gravitational field can equally well be described by
Newtonian theory as by general relativity theory. It is only necessary to modify
Newtonian theory to satisfy the demands of special relativity and so recognize the
finiteness of the velocity of light. When this is done, the theory yields the
Schwarzschild metric and satisfies the three original critical tests of general
relativity. The question of the reconciliation of the two radically different
interpretations of the physical nature of gravitation is discussed.
