  We suggest an interpretation of Einstein Equations of General Relativity at
large scales in which the Cosmological constant is exactly zero in the limit of
zero spacetime variations of fundamental constants. We argue that in a
quasiclassical Universe such variation should be tiny which leads to a tiny
value for the Dark Energy. Next, we suggest that the are two sources of the
Dark Energy. The first is the variation in Newton's constant $G_N$. It is a
form of Dark Energy in that it has negative pressure, but it differs from the
Cosmological Constant by a negative contribution to the energy. The second is
the contribution of (causal) nonlocalities to the Dark Energy.
  This comes together with a particular view of Quantum Mechanics and the
wavefunction collapse, in particular. The collapse is neither dynamical nor
subjective.
