Unified Physics and Cosmology: the Theory of Everything

Copernicus broke with 1300 years of tradition, and revolutionized science by moving from earth-centric to sun-centric view. But, moving the viewpoint to the true center of our expanding universe explains the origin and true nature of time itself. From this God’s view, Relativity and Quantum Mechanics are two sides of the same coin. Relativity is inside the light cone phenomena (since nothing can travel faster than light), while Quantum Mechanics is outside the light cone phenomena (allowing instant communications in quantum entanglement experiments). This recent paper [ Quantum principle of relativity; Andrzej Dragan, Artur Ekert, New. J. Phys. 22 (2020) 033098 ] has shown that every exotic Quantum effect like superposition, entanglement, probabilistic behavior, multiple paths etc. can be explained just by allowing superluminal possibility. The inside the light cone phenomena and the outside the light cone phenomena together span the entire region within the space and time axes. Only in unison they complete the entire picture. Both are dictated just by the scale (i.e. whether we use classical/human scale or sub-atomic scale). We failed to realize that the same spacetime is getting split into space like and time like regions based on size scale. And the reason behind this is not the magical ( ? ) speed of light. That would have turned both relativity and quantum mechanics into mere branches of electromagnetism. The true reason is much deeper and at a very fundamental level of our universe. It turns out that the c is the radial expansion velocity of our universe.  But why does the transition from Relativity to Quantum Mechanics happens with decreasing size scale? That’s because, this is what is happens to spatial and temporal dimensions at different scales: 3+1 (Classical regime) <=>  2+2 (Compton regime) <=> 1+3 (Planck regime).  From the center of universe viewpoint, simultaneity is absolute (as demanded by Sagnac effect), and there is indeed absolute universal time (as demanded by quantum mechanics). From our viewpoint (located at an awkward position in the universe), locality is absolute, and velocity c is the upper limit, and remains constant for every observer. This turns (our) space and time into inseparable twins, and makes (our) time a relative concept. This solves the time problem which had so stubbornly resisted the reconciliation of Quantum Mechanics and General Relativity. General Relativity makes things a bit tricky since it involves curvature (warping) of spacetime, but it does not become incompatible with Quantum Mechanics. The only difference between the warped spacetime of General Relativity, and the flat spacetime of Special Relativity is very similar to the difference between a stretched rubber membrane, with and without a metal ball placed on it. General Relativity and Quantum Mechanics are the two pillars of modern Science. Reconciliation of the two greatest theories of physics leads us to Theory of Everything .
