I thought I’d step in and correct an obvious misconception that you have about the force of gravity. Gravity is actually the WEAKEST force in the universe. The only reason that we can notice it at all, in fact, is because it acts over long distances and is always attractive. The electromagnetic force is much stronger by far! If you stop to think about the interactions you have with all objects (or if you study chemistry - the binding of atoms and molecules) you would see that interactions of electrically charged particles keeps you from falling through the earth! (If you don’t believe me, ask someone knowledgeable of how much space exists between the sub particles of atoms). The next strongest force is the weak nuclear force which is responsible for radioactive decay. And last but certainly not least is the strong nuclear force. This is the force that holds protons and neutrons together in the nucleus of an atom, and which holds the quarks together in the proton and neutron (quarks being constituents of protons and neutrons). All of this knowledge is available at your local library, the internet or if you so choose, from a physics class in high school or college. If you want to read a good book on the nature of matter and the universe read Stephen Hawkings’ A Brief History of Time, Hawking, S. W. Bantam Books, New York, 1996. (Sorry if I didn’t follow any citation standard.)
As far as the reason that the moon or any other thing absorbs light, I think you are either confused or misspoke. I am not completely clear on what you mean by absorbs light (so feel free to clarify any misconception I might have) but if you mean the reason that the moon is so hot on the side facing the sun; that has to do with the fact that you have no atmosphere on the moon (if at all of - that I am aware of) thick enough to block all the incoming solar energy or radiation from striking its surface. Gravity has nothing to do with this. The Earth I suppose could be said to absorb light but again this has nothing to do with gravity, at least directly, but does have everything to do with the fact that we have an atmosphere. You would be correct in saying that Black holes are able to absorb light gravitationally. Though they are the only objects I know of which can do so in such a way. Other celestial objects absorb the energy of light by the transference of energy from the light particle/wave striking and causing to vibrate one of the celestial objects atoms.
As far as gravity being the reason we experience things the way we do I think you are giving gravity more credit than it is worth. I am not sure if you are speaking metaphysically or what but gravity would have as much to do about our mind as magnetism has to do with curing our ills.
