Just several thoughts.
- Each of us might be in a different parallel universe from every other one of us. Quantum entanglement leaves this option open, since we don't really know much (anything?) about the technical side of the soul, spirit or consciousness.
- We have "discovered" very few dimensions. We might think that there are an infinite number. But we can do the math in a clear way for only the first 6. We have a reasonably clear understanding of up to dimension 11. Someone may have done the math for more dimensions, but I would guess that the number we have investigated mathematically to be under 20. It is the dimensions and their vibrations that separate the parallel universes.
- Parallel universes occupy the same place at the same time.
- Parallel universes touch each other. The "places" where they touch cause reactions in other parallel universes. These reactions produce what may be termed the material of the universe reacted upon. All material is essentially highly complex, dimensional vibrational activity.
- The aether is a "solid" made up of the parallel universes, all of them being out of "phase" with respect to all the others. "Phase" has to do with dimensional vibration, and is barely recognized or understood by dimensional theory.
- The complexity involved in the formations of materials of the various parallel universes by the interaction of other parallel universes, is so great that it will forever be way beyond anything that mankind can understand, except in the tiniest scratching of the surface of such understanding.
