In models of curved homogeneous spaces with constant curvature, everything must be the same at every point. Because no point in them can be EXCEPTIONAL, so that anything can take place in it differently than in the other points. And this must also apply to the expansion of such spaces.
Therefore, we cannot consider the expansion of such spaces as a classical expansion that originates from some center and expands its border to all sides of the surroundings, but we must replace it with an expansion that takes place equally at every point of the space. For the sake of distinction, instead of “expansion”, I took the liberty of calling such expansion of space as ECSTASY of space.
