Physics has resolved the general theories of gravity and its activity. Further research is needed to describe all the components of Gravity's phenomena as it affects many other disciplines.

Gravity is a weak force that operates through all objects. The components of gravity are useful in many studies.
See Strong Gravitational Constant
Is gravity a monopole field system? Would a two pole magnetic system only work with electric field structures in iron and electromagnets? Is gravity a single unit of force, and magnetism the multiplication of that force (that achieves a second pole).
Is electric charge the same force as gravity without a pole? Is charge an interfering force between gravitating structural elements?
Is the free light in the universe affected by gravity? Is the free light in space capable of gravity?
Does the repulsion force of gravity expelling a lighter object ever allow that object to leave it's field?
Is a medium processed (by gravity) differently under heat saturation?
Does gravity sort particles?
Why don't heavier metals sink deeper into the Earth?
Does the gravity of a planet with a different rotation cycle affect it's material components differently? Does the heat cycle (from day to night) affect the gravity in positions around the planet?
Is the alteration of gravity a field difference when celestial objects pass each other?
