Abstract
Based on a Planck scale underpinning for the universe, we deduce an expression for the gravitational constant which exhibits it as a distributional effect over all the particles of the universe. 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.
