Hidden Variables of Gravity and Geometry and the Cosmological Constant
  Problem
  We extend General Relativity by adding $4$-form field strengths to the
gravitational sector of the theory. This promotes Planck scale and the
cosmological constant into integration constants of these $4$-forms. When we
include the charges of the $4$-forms, these `constants' can jump discretely
from region to region. We explain how the cosmological constant problem can be
solved in this framework. When the cosmological constant picks up contributions
from two different $4$-forms, with an irrational ratio of charges, the spectrum
of its values is a very fine discretuum. If the membrane charges satisfy
$\frac{2\kappa_{\tt eff}^2 \kappa^2 |{\cal Q}_i|}{3{\cal T}^2_i} < 1$, the
discharge processes populating this discretuum dynamically relax $\Lambda$,
ceasing as $\Lambda$ approaches zero. Thus the theory exponentially favors a
huge hierarchy $\Lambda/\mpl^4 \ll 1$ instead of $\Lambda/\mpl^4 \simeq 1$.
