Superluminal Dark Spacetime Domain

What if vacuum free space is actually a totally different thing from what it appears to be? What if dark energy and dark matter are not the only hidden things in our universe but a whole different dark spacetime dimension sector that is hidden and made not directly observable to us? In this scenario dark energy and dark matter would reside in the special case of a physical de Sitter spacetime which would be entangled and in superposition with our normal Einsteinian luxons spacetime. This unknown dark spacetime sector or domain we claim is what appears to us as vacuum free space and as “nothing” although the exact opposite is true. Our current ongoing research shows that, what we observe as vacuum free space is actually a type and unknown phase of superluminal vibration energy by an omnipresent non-tachyonic graviton condensate that is the basic substrate upon all quantum fields come to existence in our normal spacetime. Why we cannot observe this hidden dark spacetime is because its intrinsic superluminal nature that makes it to be out of phase from our light spacetime.
