<br />Any Theory of Everything needs to first look for the Origin of Gravity<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">Welcome to the 21st century, when the origin and nature of gravity and all those things you mentioned as unknowns are now finally known and well understood. See the "Gravity" sub-tab at the "Cosmology" tab on this web site (start at "Home" on the Message Board), articles in our Meta Research Bulletin over the past 14 years, the 20-author book "Pushing Gravity", and especially the "Gravity" CD available through our web site store.
BTW, it turned out that both Mach's Principle and the Equivalence Principle were misleading us, which in large part is why it took so long to figure out gravity. Especially, understanding how gravitational force could act so much faster than light signals can travel was a major impediment that you did not even mention.
Note that your remarks about changes in G are based on a misunderstanding. It is little g, the acceleration of gravity at Earth's surface, that increases as we move inward for well-understood reasons. (We are getting closer to the densest parts of Earth's mass.) In contrast, no changes in big G, the universal gravitational constant, have yet been detected down to less than a part per billion. -|Tom|-
