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).
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. Reconciling the two leads us to 'Theory of Everything'.
The list of achievements in my above-mentioned paper is simply too long to be detailed here in this email. [e.g. ‘Principle of Least Action’ which comes closest to the ‘theory of Everything’ in physics, and from which, all known laws of physics can be derived, arises as a direct consequence of the better model of the universe as proposed in this paper]. My paper also explains why dualities like wave-particle duality, or Lagrangian-Hamiltonian duality arises. Duality is a bedrock concept of modern physics.
Nature, the ultimate judge, has stamped TOTALLY APPROVED on my paper.
