There is no dark energy in the Kasner metric, neither is there a cosmological constant. There are no "flows in the ground state of Einstein space-time", and there is no "thickness" associated with space-time. The Kasner metric shows no such thing. All it shows is that space-time expands anisotropically. The Kasner solution is simply a cosmological metric, it makes no prediction as to the topology of the universe. "Density of Einstein space-time" is a meaningless term, and entanglement of particles has nothing to do with any densities. Oh I understand your simple sentences very well. That does not however make them any less wrong. Are you not tired yet of constantly inventing fairy tales ?
