Origin of Quantum Space-Time and Primordial Black Hole

In the present theoretical work, an attempt has been made to derive an expression for the quantum volume of discrete space and its growth rate using first rank tensorial Einstein-Gauss gravitation law, Einstein’s mass energy equivalence and Heisenberg’s uncertainty principle. It is found that the universe may have come into quantum existence with volume thrice the Planck’s volume within the framework of physical laws when it already had an age ~10^﹣43 s provided the Planck’s time is at the origin otherwise, both have the same origin. The size and gravitational field of quantum primordial black hole of quantum mass have been estimated and reported.
