In special relativity speed of light is constant for all observers at any frame of reference but as Einstein proved later in some of his papers [ ] this is not the same case in general relativity when you have an accelerated frame of reference i.e. a deference in space-time curvature then the speed of light will be different for only a non-local observers, so by following this line of work I manage to confirm and develop Einstein work. I found that the minimum mass to affect space-time is half Planck mass and I name it At-Tariq condition because in black hole the multiples of this ratio will create a higher-time dimensions and it will act as if the event horizon hammering towards the singularity Then I use it to solve some important problems in general relativity such as Calculate the cosmological constant using the quantum field fluctuations with an accuracy of (93.5%) of the average accepted experimental results i.e. theoretical calculations( Λ≅-1.4028×〖10〗^(-9) (J.m^(-3) ). A proper solution to the vacuum catastrophe. Calculating the dark matter density using third order quantum field fluctuations within high accuracy from the average accepted experimental results i.e. theoretical calculations. ;Dark matter density=5.3964586×〖10〗^(-27);(kg.m^(-1).(s.c)^(-(4) ) )≡(kg.m^(-3) ) Experimentally the dark matter density in the universe is around (5.423×〖10〗^(-27);(kg.m^(-3) ) )in the assumption of a flat universe then this will put our results to be within an accuracy of [96%] from the average current experimental values. Proving the effect of the gravitational blue shift of a gravity well, on the electric permittivity of free space (ε_∘ )through both mathematical derivation and experimental evidence using a vertical variation of the Michelson-Morley experiment. Finding a definite mathematical solution for the black hole singularity. Finding a definite mathematical solution for the big bang singularity at (t≤0) in cosmological constant form and driving the gravitational constant from it. Constructing new black hole thermodynamics and finding the entropy of the vacuum. Constructing Newton's universal law of gravity from the Schrödinger equation. A way for altering and manipulating space-time through cooperation between the relativistic mass and Schwarzschild metric to increase its curvature through what I like to name "the hoofing effect".
