The resolution may require some entirely new insight, such as Newton realizing that he needed to invent Calculus to solve the problems he faced three centuries ago. A possible area to investigate more precisely and thoroughly, is the behavior of the Trojan asteroids. One of the few exceptions is the behavior of those Trojan asteroids. They orbit the Sun in meta-stable orbits which have effectively the same radius as Jupiter's orbit, but they permanently remain 60 degrees ahead of or behind that planet as they orbit the Sun. There are several large Trojan asteroids in each of these two groups.
Several questions come to mind.
Much more research is necessary in these areas, and they might contribute toward a more complete theory for Gravitation. . The Globular star clusters, which are outside of but near our Milky Way Galaxy, involve a number of logical mysteries. These facts in themselves do not present any compelling mysteries to me. However, there are two different circumstances in their environments that DO seem to have quite illogical consequences. In the vicinity of the Sun, there is believed to be an average of about 0.0014 solar mass of stars per cubic light year.
