A new formulation of the Friedmann-Lemaître-Robertson-Walker equation
has been developed in a previous paper. The present study analyses an
alternative approach to the cosmological constant Λ from the perspective
of the so called CBU model (Continuously Breeding Universe). Instead of
having a cosmological constant responsible for the expansion, an excess
pressure is boosted by a bang factor β. It is assumed that expansion is
caused by the continuous addition of matter, due to, say,
electron-positron fluctuations. Even if only a fraction of virtual pairs
stay alive, while the majority returns to nothingness, the phenomenon
is vigorous enough to explain the expansion. The momentum change due to
the inflow of new matter provides a force and accordingly a pressure
explaining the expansion. An equation of said pressure is derived and
then interpreted as the equivalent to the cosmological 'constant', Λeq. The momentum pressure provides a perfect match to the dark energy density.
