Since there were so few papers on this I wonder if many will have a perspective on this issue? I hope so. GR has to lead into QM?

There is a historical developement here that many do not need to be reminded about, but for a laymen, it was very important to undertand this developement in concert with current technolgical realites. This is a GR generalization and next I hope to demonstrate the other extreme of the Heirarchy problem in terms of Geometrodynamics.

Membrane Realization?

An Introduction to Geometrodynamics

The existence of gravitational waves is a prediction of the General Theory of Relativity which is Einstein's explanation of the gravitational interaction (1915). The basic idea is:

Gravity is no force but an aspect of the geometry of spacetime.

Space is not an absolute invariant entity, but is influenced by the distribution of mass and energy in the Universe. The basic principle is:

Matter tells space how to curve, and space tells matter how to move.

Large masses introduce a strong curvature in spacetime. Light and matter are forced to move according to this metric. Since all the matter is in motion, the geometry of space is constantly changing. Hence Geometrodynamics is a better name for Einstein's theory of gravitation. In order to derive the basic field equation, one has to relate the curvature of space to the mass/energy density:

G = k T

This will not answer the direct comparsion just yet Marcus, but I hope to demonstrate where I think it will lead too. I will back off now and hopefully we can will see a direction (quantum geometry) this forum takes, as well as sci.Physics.strings or even Peter Woit:)

Is this okay Marcus?
