Data gathered in the study, however, overwhelmingly contradict the conclusions of the authors. Violent crime rates are, in fact, drastically higher in sanctuary cities than their non-sanctuary counterparts, as is evidenced by the chart the authors used to delineate their conclusion.
The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object's centers. Altering the separation distance (d) results in an alteration in the force of gravity acting between the objects.
Kepler's 3 laws are descriptions of how 2 bodies move if the force between them is an inverse square attraction. He derived them from experimental observations of planets and so they are 'correct'. Newton later calculated that an inverse square law would explain these properties of orbits and so decided that gravity followed this equation.
