Why does String Theory require 10 dimensions? What are higher dimensions? If 4D is time, why are people acting like we're just now getting there? Here is the explanation for String Theory.

Extra dimensions in string theory

Superstring theory is a possible unified theory of all fundamental forces, but superstring theory requires a 10 dimensional spacetime, or else bad quantum states called ghosts with unphysical negative probabilities become part of the spectrum.

SO, the real reason string theory requires 10 dimensions, consistent with the 10 spheres of Jewish Babylonian Kab-Allah, is because otherwise you could have a universe with "GHOSTS"

Seeing as I have met several ghosts, including a scary run in with a reptillian dragon spirit whose face came out of my computer screen like a hologram, so I'm inclined to go with the D-4 model. I have also seen two spirits who briefly flashed within my imagination, the image of themselves in their chosen environment.

I propose a normal dice. A D6 model, in which the inner reality of conscious beings is a dimension onto itself, which the ghosts can possess incidentally. I know it probably doesn't resolve the unified field theory, but I just don't see where you have other dimensions. I have seen imagining the 10th dimension, but that seems like more of dimensions 1-4 only bigger. My Thoughts:

0D = God. Nothing is also everything. To have no size is to be everywhere. Perhaps also 7D

1D = Strings, having only positive and negative end. The binary code of the Universe.

2D = Holograms, Spirits are 2D. They enter into 3D bodies. Otherwise they are not subject to time.

3D = Three Dimensions spacial bodies enter into 4D Time and interact with 3D limitations.

4D = Within the 4D time alloted, the 1D predestined strings within the 2D souls, within the 3D bodies, create 5D within themselves.

5D = A single dimension within ourselves though we can imagine all 4 dimensions and sound. the knowledge of our ever advancing civilization is also found within and our knowledge may be transferred to records and a cybernetic dimension of information. We may possibly create 6D worlds of cyberspace which could become inhabitable in some form. Basically, 5D is everything we are creating in 4D, just as 4D is everything we do in 3D.

6D = Is interesting in that God perfected creation in 6 days and created man. If 6D exists as I have described then a whole new universe has been created within cyberspace, or 6D is a single dimension within a blackhole, that has become a new universe.

7D = Resting, because the newly formed universe continues the previous 6 dimensions. In a way it rests and creates new 6 dimensions within itself. This is, I think, where the ghosts are hiding, and the throne of God, because it is eternal and timeless.

universes expand and stars eventually burn out. God is eternal, I believe there must be some means for new universes. 2D Spirits could also potentially enter into advanced robots with AI. That is just another form of 3D body.
