  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.
