  It is shown, from the two independent approaches of McCrea-Milne and of
Zeldovich, that one can fully recover the set equations corresponding to the
relativistic equations of the expanding universe of
Friedmann-Lemaitre-Robertson-Walker geometry. Although similar, the Newtonian
and relativistic set of equations have a principal difference in the content
and hence define two flows, local and global ones, thus naturally exposing the
Hubble tension at the presence of the cosmological constant \Lambda. From this,
we obtain absolute constraints on the lower and upper values for the local
Hubble parameter, \sqrt{\Lambda c^2/3} \simeq 56.2$ and \sqrt{\Lambda c^2}
\simeq 97.3 (km/sec Mpc^{-1}), respectively. The link to the so-called maximum
force--tension issue in cosmological models is revealed.
