I gave a decription of DeSitter space(dS) and AdS that left out one point. There are points on the energy scale that are Points of symmetry breaking. Coupling constants for the forces vary along that scale and merge at those points. ie the electromagnetic and weak force merge at one point, then merge with the strong force at higher energies. At those points, the symmetry breaking causes an increase in the vacuum energy. A reappearance of symmetry would cause a decrease.
As far as Im concerned the reconciliation of physical and spiritual realities vis-à-vis Revelation falls in the category of musings and thus either of us could be right or (more likely) we are both wrong. LOL! Well see.
At some point in the breaking of the seals, God will shatter the illusion held so strongly by the atheists that the physical realm is all that there is. I believe that occurs here, setting up the outpouring of the wrath of God which precedes Christ's millennium rule on earth:
And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb: For the great day of his wrath is come; and who shall be able to stand? Rev 6:12-13
And I do agree that the big rip occurs in Revelation 21 the creation of the new heaven and earth. The difference I perceive is that this physical reality remains to some extent in Revelation 6 (sixth seal) - for the final, seventh seal and Christ's thousand year rule on earth (the Sabbath of Adamic man using the 7,000 year Jewish interpretation, the week allotted to Adam.)
As to the physics, we are approaching the same subject from different aspects - akin to wave/particle duality.
You identify dark energy as the vacuum (of space.) I identify dark energy as an outdent in the fabric of space/time, the opposite of a high positive gravity, space/time indent.
For the Lurkers: gravity can be visualized as a particle, a graviton. It can also be visualized as the geometry of space/time.
The effect on the expension/acceleration of the universe is the same.
Or to put it in other words, I see energy/matter being created as the universe expands a geometric change being the cause of energy/matter. I suspect you see energy/matter being the cause of the expansion of space/time.
In either case, space/time and energy/matter are phenomenons of the expanded universe.
Likewise we are looking at dimensions from two different aspects. You are perceiving extra-dimensions as compactified (string theory) whereas I am perceiving expanded dimension(s) from the big bang (higher dimensional dynamics.)
Perhaps that is why you have confidence in CERNs upcoming test to observe the so far undetected Higgs field/boson?
At any rate it always seems to come down to what we consider to be real.
In my view, at the root, physical reality is all geometry. Or as Einstein dreamed, to transmute the base wood of matter to the pure marble of geometry, I too assess the "marble" of the equation as the geometry.
Again I aver that it may be that what we detect as particles in four dimension space/time may actually be massless, i.e. shadows of extra-dimensional momentum we cannot detect (yet.) And further that these particles may be multiply-imaged from as little as a single particle in a higher dimension.
But again, well see.
At any rate, as I mused in 7900 - this physical reality, is like a stage play that was being performed for Adams benefit to reveal properties of God, e.g. that He is Good and not evil. But Adam jumped on the stage so here we, his descendants, are with a huge observer problem. We cannot clearly see the spiritual reality from here which is to say, while yet in the flesh. But that will change for all mortals when the heavens are rolled back like a scroll - or in the metaphor, the curtain (or firmament) falls. But the spiritual reality (in the metaphor, the audience) is what "all that there is" is "about."
The geometric scenario Ive outlined above fits that scenario to a T. But yours would work as well.
But well see
Oh, and I do not have a leading in the Spirit one way or the other whether the firmament is the speed of light as suggested in the Jewish interpretation. But I do have a Spiritual leading that it is a boundary which is not geometric per se - the spiritual "there" and physical "here" are not necessarily spatially separated. But what that boundary "is" (the curtain in my stage play metaphor) I don't know.
