An Overview of Topological Geometrodynamics

Topological Geometrodynamics (TGD) was born as a possible solution to the special-general relativity discrepancy. Space-time as a 4-D surface was the radically new vision about the fundamental ontology. The new view leads to notions like many-sheeted space-time, topological field quantization, sub-manifold gravity, geometrization of classical fields in terms of sub-manifold geometry and of standard model quantum numbers, and eventually to geometrization of Feynman diagrams in terms of space-time geometry having highly non-trivial implications also in the macroscopic length scales. The introduction of p-adic number fields leads to the generalization of the notion of space-time so that it also allowed p-adic regions for various values of p-adic prime. The construction of quantum TGD led to the idea about physics as a geometry of "world of classical worlds" (WCW). WCW spinor fields (formally purely classical objects) would define the quantum states of the Universe. Quantum measurement theory is generalized to a quantum theory of consciousness relying on the notions of quantum jump and self. These notions are identified in the simplest formulation. The new ontology implies highly non-trivial predictions in all length scales and is especially relevant for TGD inspired quantum biology and consciousness theory
