Dear Carlos
What is new about my proposal is that curved spacetime is a macro-quantum "supersolid" effect in which the 4D world crystal lattice (or "simplex") distortion field, i.e. tetrad is precisely akin to the superflow field of He4 below Lambda. The nodes of the 4D world crystal lattice generally covariant "aether" are precisely the nodes of the post-inflation Higgs-Goldstone coherent vacuum fields where the huge random zero point energies of the pre-inflation false vacuum are converted to the smooth c-number "ODLRO" fabric of space-time. Hence an intuitive explanation for why the cosmological constant is small and positive, albeit in the context of Linde's eternal chaotic inflation on a populated cosmic landscape as Lenny Susskind suggests even though Lee Smolin does not like it. However, Smolin's objection is overcome because in my theory, beyond Lenny's, the other worlds are directly observable, hence Popper falsifiable, via two distinct mechanisms
1) dark-energy supported traversable wormhole "star gates"
2) Antony Valentini's "signal nonlocality" because macro-quantum effects violate "sub-quantal heat death."
Evidence for this is precisely the UFO data that mainstream physics mistakenly rejects. From my numerous contacts inside USG Intelligence I know the UFO evidence is real.
