de Sitter SpaceTime’s maximally symmetric
curving constantly positive solves vacuum
equations for Einstein’s cosmological
Approximates early universal inflation,
accounts for an energy density
relational increase to cosmic expansion.
On entering a second de Sitter phase:
a transition from a large cosmic constant
with a tiny radius of curvature
to the future de Sitter dark energy
emergent of the constant current;
the radius of curvature close to Hubble scale.
