This theory is fundamental physics theory.I tried to describe spacetime from new approach.I also tried to link General Theory of Relativity and Quantum Mechanics. I'm really sorry for the wrong translation in the first sentence of the manuscript ... It should be:I think that spacetime behaves as diffraction pattern,which slit moves through superspace with speed of light.My conclusions becomes from Heisenberg's relations and spacetime characteristics-it is isotropic and homogenuos(that the reason why it has to be invariant for all inertial systems). I devoloped new approach to black holes physics and spacetime quantization.This theory is fundamental physics theory.I tried to describe spacetime from new approach.I also tried to link General Theory of Relativity and Quantum Mechanics. That link are black holes and spacetime quantas. The theory isn't finished yet,but there are given some predictions I have found till now. In context is given brief math I have used in the theory for better understanding.The theory isn't complete yet,but it would be great if You cold give some comments about the research. I linked Quantum Physics and General Theory with principal function (S=mc Int ds) and S=int Ldt where L is lagrange function.ds is interval in Theory of Relativity.We have to calculate Lagrangian of perturbated 3D Harmonic Isotropic Oscillator. I did it and got it as some form of hypergeometric function 2F1(a,b,c,z).
