Query: No single unification theory of everything   In light of G\"{o}del's undecidability results (incomplete theorems) for
math, quantum indeterminism indicates that physics and the Universe may be
indeterministic, incomplete, and open in nature, and therefore demand no single
unification theory of everything. The Universe is dynamic and so are the
underlying physical models and spacetime. As the 4-d spacetime evolves
dimension by dimension in the early universe, consistent yet different models
emerge one by one with different sets of particles and interactions. A new set
of first principles are proposed for building such models with new
understanding of supersymmetry, mirror symmetry, and the dynamic phase
transition mechanism - spontaneous symmetry breaking. Under this framework, we
demonstrate that different models with no theory of everything operate in a
hierarchical yet consistent way at different phases or scenarios of the
Universe. In particular, the arrow of time is naturally explained and the
Standard Model of physics is elegantly extended to time zero of the Universe.
