Dear Janko,
thanks for you kindness and for your good judgement on my work.
There are two points of view concerning gravitation: the Einstein's geometric point of view and the Feynman's particle point of view. The Quantum Gravity Theory, if it will be ultimately find, should be the definitive synthesis of them.
Actually, my research work is based on Einstein's geometric point of view. Which is the correct background metric depends from the scale of the intrinsic curvature. If the scale is not too large the Minkowkian flat space-time remains the background space-time. In fact, Equivalence principle is preserved, thus the space-time, even if globally curve, remains locally flat.
I regret, I am not an expert of elementary particles and of Feynman's particle point of view, thus, I cannot judge your papers.
Cheers,
Ch.
