This solves a long standing puzzle, the so called Weinberg formula which gives a microphysical parameter in terms of a cosmic parameter. This was also discussed on the basis of a cosmology that correctly predicted a dark energy driven accelerating universe - the linkage is now established.20 pages Tex : Special invited talk at the Sixth International Symposium on Frontiers of Fundamental Physics, University of Udine Italy; based on a paper to appear in Foundations of Physics LettersGeneral Physicstext
