Gravitation is the force of attraction that exists between all particles with mass in a universe. It is the force of gravity (also called gravity fields) which is responsible for holding objects onto the surface of planets and, with Newton's law of inertia, is responsible for keeping objects in orbit around one another. Any two objects exert equal and oppositely directed gravitational pull on each other.

The speed of gravity is instantaneous; the effective time interval between an increase in an object's mass (which would produce extra gravitons) and the arrival of those gravitons to another mass (regardless of distance) is effectively zero*. This is the reason that the destruction of Amargosa on StarDate 48632.4 changed the entire gravimetric configuration of the surrounding sector instantly rather than over the course of twenty years.
