The Consequences of a Strengthened Newtonian Gravity at Short Distances

摘要

A central interaction of bodies which at short distances is stronger than Newtonian is considered. It is shown that the escape velocity from a body is essentially more than the escape velocity given by Newton’s theory. The connection of the new central interaction with the gravitational radius of a black hole is found. It is shown that the gravitational radius of a black hole may be arbitrarily large.
