This means physically that for a general spacetime there is no single procedure for constructing a Gaussian surface that contains the mass-energy. A spherical space with matter evenly distributed around it has no such ADM definition of mass-energy. So for zero net energy, which is the contact manifold of integration we have E = K + U = 0 for K kinetic energy and U potential. So K = ½mv^2 and for galaxies of mass m in a region with energy density ρ the potential energy in a region of volume V = 4πr^3 is
U = -4πGmρr^2/3. So E = 0 = ½mv^2 - 4πGmρr^2. The radial distance is then r = xa, for x a ruler distance. It is clear this divides out and we can get the equation (a'/a)^2 - 8πGmρ/3 = 0 --- a' = da/dt. Except for the k/a^2 term in the general relativistic form, where for flat space k = 0 anyway and for a large is not a big contributing factor, this is the Friedman-Lemaitre-Robertson-Walker (FLRW) equation for standard cosmology. The Hubble parameter is H = a'/a.
