Abstract
Newton’s hesitation to publish his Principia was presumably caused by his inability to explain why volumes were irrelevant to radial action of gravity, which appeared somewhat incomplete without possible nonradial effects. His doubts about completeness of his gravitational theory are justified by results from several 20th century experiments, which suggested presence of a nonradial impact of gravity in addition to the radial attractive force that he has introduced. Existence of nonradial effects is implied by mathematical and physical preconditions, if total energy is to be conserved, and it has already been confirmed by experiments. Nonradial potentials do not affect directly the radial Newtonian potentials, which generate the radial force of gravitational attraction between bodies, but they decrease energy of the rays that run across gravity fields. The nonardial potentials also contain repulsive effect of gravity that becomes dominant at very large distances where the usual attractive radial force practically vanishes. They provide thus global mechanism for an accelerated expansion of the universe and so they explain the lack of superclusters in it. They also imply gravitational contraction, yet another new long-range effect that may explain formation of galaxies.
