Answer:

In Newtonian Gravity, space is like 3-dimensional graph paper, and objects (earth and moon etc.) are moving through space at an absolute time. The object's (earth's or moon's etc.) path curves because a force is present. Without that force (gravity) objects (earth or moon, etc.) will continue in a straight line.

Where Newton's idea of Gravity is 3D space with Time a constant, Einstein's view of gravity is explained by 4D space -- called space-time. In this structure, time is not absolute but a dimension or variable in the structure such that (x,y,z,t) exist for a given event. Objects (earth or moon) moving through space-time curve not because they are "pulled" by the force of gravity, but because they are taking the shortest distance through curved space-time.

For Einstein, you can have curved space-time without matter so an object might start moving in curves even if nothing is present.

We have been discussing the parallel between Newton’s Universal Law of Gravity and Coulomb’s force law: • Both laws define force. Coulomb's law describes the force between electric charges whereas Newton’s law describes the force between masses. • Both are inverse square laws. The forces are proportional to the inverse square of the distance between masses for Newton’s law and the inverse square of the distance between charges for Coulomb’s law. • The forces defined by both laws are central...
