Then space is a torus

Dual curvature is at both ends. Dimensional analysis gets us there.

If the vacuum is at its limit in the proton, then it must have an equivalent limit orders up.  It is bounded at one end, it cannot be open at the other, but light is still light, three dimensions is our limit.

 We don't big bang, that is an illusion from local space flux. It is like looking at the torus and seeing a sphere, we dimensional  overlap on the upper rate limit in the vacuum. Our local flux makes it so.

 It is not that we have boson duplicate universes. The universes  are separated by large fuzzy constant of vacuum, the hole in the torus. But we are not disconnected, we share one dimension.

The vacuum must be in mild flux between universes.

 The proton torus makes the mass, it optimally compacts vacuum leaving neutral vacuum voids at low energy, we pass the vacuum as a sparse lattice, as if it were an aether, like my pal Lord Kelvin. The vacuum really does make snake coloring operators, like a quantized current in water.

If our mother quasar is between universes, then in this dual curved geodesic layer, the vacuum flux easily incoming and outgoing on two opposite paths.  We would likely not observe ours, easily, but the quasars we see are again, across the torus hole, and coming at us in duplicate paths. Locally, anywhere we have compressed vacuum we will have vacuum expansion. On our boundary, vacuum depletion.

We big bang, in slow motion a little at a time. The mother quasar uses vacuum flux to maintain separation.

Mass is the actual relative movement of vacuum. But light gives the effect as it can recolor the deviation counts. The better model is stationary mass and movements of vacuum deviations  through the matter lattice.   If we have local expansion of space, then it is stronger the more that mass is compressing, it appears like energy gain from higher quantization. then we have gravity, objects gaining orbit to maintain curvature vertical. It is the apparent motion of vacuum deviations, L spots are real balance point for curvature in the vacuum. The notions of time and space can be approximated well, I would think.  Looking in 12 spots in the sky, sharing one dimension; then apply the whole set of Einsteins,  two at a time.  Decode that red shift along two hypothetical paths, or try a two sided curvature in space time. Then see if the red shift can be partitioned across one axis, R distance out, and note the Einsteins you did. You can  reconstruct the torus.

Albert needed a second order cosmology constant, but he is right, twice in a row, then its back to the future.
