Abstract: The standard model of the big bang of the universe,which holds that the expanding universe originated from the big bang of the point,when the universe time tc=0 and the universe radius rc=0,incurs censure constantly.If the unification formulas calculating the mass and the radius of celestial bodies and particles are extended to transend Planck scale,the conclusion can be drawn that the universe originated from the big bang of the "super-micro black hole".Recently it is put forward that the expanding universe originated from the big bang of the "pre-universe",by which the theory of the big bang of the point is denied,and both the theories of the "pre-universe"and our"super-micro black hole" are different in approach but equally statisfactory in result.Some strange phenomena about "super-micro black hole"and "pre-universe"restricted by relativity,quantum theory and statistical mechanics are discovered.
