Yes, the non-mathematical summary is that it doesn't act at a distance, it acts purely locally. Esentially, you can write the equations for gravity in a differential form, which means that all of the quantities are defined locally and affect each other only locally. This is analogous to the situation in electrostatics, where you can write Coulomb's law (which appears at first glance to act at a distance) in the mathematically equivalent form of Gauss' law (which is purely local).Has there been any deeper understandings in how gravity acts at a distance
