A generation of scientists, after Newton’s discovery, made that effort to find a cause of gravity and failed to find the answer. Then they gave up and allowed for an explanation that violated causality, the basic law of physics. No explanation that violates causality is a legitimate scientific explanation! They had, inadvertently, “reintroduced the occult forces of the medieval scholastics”! As great as Newton’s discoveries were to the advancement of science, this issue represents a problem that continues to be with us today in theoretical physics.
