I am wondering why if quantum mechanics is self consistent, equal to itself, and thought to be equal to reality, and the same can be said of the theory of Gravity, why the separate theories and equations can not be plugged through a process of guess and check/trial and error by supercomputers even, to arrive at the compatible solution? Also this may be a separate question, but I am curious to know what the most agreed upon view is of what the manifold or field that is responsible for the existence of gravity is/is like and how it exists? Also, is that field coupled to the EM field, as I know EM radiation follows the shape of that field? Would this make them two sides of the same coin so to speak? Also, is it agreed upon that the Gravity field and EM field take up every infinitesimal point within the universe at all times, or within the universe are there, if even the smallest quantities, areas of pure, absolute nothingness? This is my first post, I hope this is in the correct forum, and I hope these questions can be discussed, thanks.
