Physical premise (IDWT): Physical spacetime has infinitely many ordinary spatial dimensions plus time. Matter occupies up to ten spatial dimensions; all remaining spatial directions are unbound for every particle. Depth counts a pattern's bound spatial involvement within that space. “Observed” and “unobserved” describe an observer's access, not different kinds of dimension. Older projective and nested-geometry calculations below retain their additional hypotheses; they do not establish a separate physical manifold or compactified direction. See spatial meaning and mathematical scope.

43. Implication for visible-unobserved collision correlation

The proposed spatial-correlation mechanism no longer requires the higher-dimensional force law to look like a six-dimensional version of Coulomb's law.

It is sufficient for the master interaction to decompose as

K6=Klift+N, \mathcal K_6 =\mathcal K_{\rm lift} +\mathcal N,

with

MKliftL=KEM, M\mathcal K_{\rm lift}L =\mathcal K_{\rm EM},

and

MNL=0, M\mathcal NL=0,

while N\mathcal N acts on the real depth-six relative state.

For example, a fibre-divergence or vertical-derivative term could alter

P(Bhid∣Bvis) P(B_{\rm hid}\mid B_{\rm vis})

without directly changing the marginal electromagnetic operator seen in the lower sector.

The remaining nontrivial requirement is reciprocity/backreaction: after the unobserved state responds, the complete observable dynamics must still reproduce experiment. This imposes a stronger effective condition than the direct sandwich alone.

Therefore the next calculation is to construct the minimal self-adjoint covariant element of the projection kernel that can correlate the unobserved relative coordinates, and then compute its Schur/pushforward backreaction.

That is a much sharper target than asking for an arbitrary six-dimensional force law.
