In this paper, the statistics of excitation-tangles in a postulated background ideal-superfluid field is studied. The structure of the Standard Model is derived in terms of tangle vortex-knots and soliton. Gravity is observed in terms of torsion and curvature in the continuum. In this way, non-linear dynamics and excitations give rise to a unified field theory as well as a Theory of Everything. As a result of this unification, spacetime and matter are shown to be fundamentally equivalent, while gauge fields arise from reorientation and excitations of the the fundamental underlying field. Finally, the equivalence of topological and quantum entanglement is explored to posit a theory of everything in terms of long- and short-range entanglement between fundamental quantum units (bits) of information.

We have used Mn K–edge absorption and Kβ emission spectroscopy to determine the oxidation states of the Mn complex in the various S states. We have started exploring the new technique of resonant inelastic X–ray scattering spectroscopy; this technique can be characterized as a Raman process that uses K–edge energies (1s to 4p, ca . 6550 eV) to obtain L–edge–like spectra (2p to 3d, ca . 650 eV). The relevance of these data to the oxidation states and structure of the Mn complex is presented. We have obtained extended X–ray absorption fine structure data from the S 0 and S 3 states and observed heterogeneity in the Mn–Mn distances leading us to conclude that there may be three rather than two di– μ –oxo–bridged units present per tetranuclear Mn cluster. In addition, we have obtained data using Ca and Sr X–ray spectroscopy that provide evidence for a heteronuclear Mn1Ca cluster. The possibility of three di– μ –oxo–bridged Mn–Mn moieties and the proximity of Ca is incorporated into developing structural models for the Mn cluster. The involvement of bridging and terminal O ligands of Mn in the mechanism of oxygen evolution is discussed in the context of our X–ray spectroscopy results.
