Our Universe was born from Minimum Gravitational Black Holes (its mass ≈ 10-5 g), but not from Singularity or Big Bang of Singularity. 2. No Singularity existed in star-formed Schwarzchild’s black holes, but a steady mini black hole (its mass ≈ 1015 g) of long lifetime would certainly exist inside as a core
to obstruct the collapse of energy-matters to become Singularity. The steady mini black hole (mom ≈ 1015
g) in black holes instead of Singularity called by General Theory of Relativity (GTR) could resist the
gravitational collapse. [Nature and Science. 2004;2(3):1-4].
