This book on Unified Theory is an update on the 1990 book 'Unified Physical Theory', the 2002-book Realistic Foundations of Physics & Cosmology and the 2010-book THE UNIFIED THEORY A complete paradigm shift in Physics & Cosmology. In a paradigm shift the Unified Theory singly presents the grandest ever 'unified' replacement for the Relativity, Quantum, Quark-lepton, Higgs, Electroweak, Supersymmetry, String & Big Bang theories. New Priciple of Null Action replaces the Uncertainty Principle. Findings of the 1990-Physics Nobel lauretaes and conclusions of 2011-Physics Nobel lauretaes are contested. The Universe does NOT have accelerated expansion and will not end as an empty space. Reader will be amused to count the number of Nobel laureates whose work and thought have been correctingly commented on. This present book will serve as a source to revise the syllabai and textbooks at the University & College levels of Physics, Astrophysics, Cosmology &c., Book is worth translation into major languages of the world.
