I've come up with errors in man's understanding of gravity. They're listed in the comments, if this is something that you find interesting. Otherwise, less space has been taken up :)

1) Consider an enclosed system of me and you. (I’m ignoring the Uncertainty Principle here for convenience). One can calculate the attraction due to gravity between two human bodies, A & B, given their masses and distance of separation. But this of course isn’t accurate. It's not really the case that bodies A and B are gravitationally attracted to each other! It’d be more accurate to consider every cell in body A, and work out the force vectors of attraction to all the cells in body B. Then sum up the vectors. It’d be more accurate still to consider all the atoms making up body A and work out their attractions to the atoms in body B. We could then predict what would happen with even greater accuracy.
One can imagine this situation analysed at greater and greater accuracy, using the known masses of neutrons and protons, and then of quarks etc. My question is, if this process can be continued indefinitely, providing greater and greater accuracy of the situation, in what sense could the attractive force of gravity observed between bodies A & B ever properly reflect the 'correct' quantity and distance of separation between all the chunks of matter making up bodies A and B? I’m thinking of the universe as a computer - it has to somehow do things to the smallest particles of mass, not to the large ones as we observe! So how can the computer carry out its operations unless it has smallest pieces to work with?
Does the fact that gravity attracts two bodies by a definite magnitude and in a precise direction therefore suggest that there is a fundamental particle of some kind, which is the smallest essence of everything? Or is this lack of preciseness with gravity itself unless a fundamental fact of reality?
(All of this ignores the Uncertainty Principle; the errors in predicting this grav. force would only be multiplied if you considering this - I’m merely saying that there might be uncertainty quite apart from measurement!!).
2) Does gravity act INSTANTANEOUSLY? That is, does gravity have an automatic, instantaneous ‘knowledge’ of where you are? So if you are moving at just under the speed of light, and you pass a heavy body which you are attracted to with a force of say 50N….a few nanoseconds later, when you are far away, has the force of gravity immediately diminished given the fact that the separation between the two objects is now greater? Or is there some kind of ‘adjustment’ period, during which the “universal computer” learns of your new position? This could be possible if gravitons are not all-pervading particles, that is if they are rare enough for an object to pass in between areas where gravitons are not present. In such a case, gravity could be ‘shielded’, that is objects could employ a shield so as to never fall down to the ground !!!!
