  From the Eddington-Weinberg relationship, which may be explained by the
holographic principle and the cosmic coincidence in a flat Universe, it follows
that the characteristic gravitational acceleration aN associated with the
nucleon and its Compton wavelength is of order the Hubble acceleration H0c in
this epoch. A natural scaling for the cosmological constant is obtained from
this acceleration term. It also happens that the critical acceleration a0
associated with the MOND theory is of order aN.
