Abstract
Using the quantum corrected Friedmann equation, obtained from the quantum Raychudhuri equation,
and assuming a small mass of the graviton (but consistent with observations and theory), we
propose a resolution of the smallness prroblem (why is observed vacuum energy so small?) and
the coincidence problem (why does it constitute most of the universe, about 70%, in the current
epoch?).
