This reasons are: 1) BB expects shaping 3D space from 0D zero point. This impossible. 2) BB expects the expansion of space at the speed of light. If BB began with flashes of the light, then the universe on today look like empty sphere by radius 10 billion light years with the background cosmic radiation existing on a border only. Obviously this not so. 3) By single reliable fact is "confirm" the expansion of universe may be considered a red shifting of the spectrum of light radiation of stars. But. This phenomena gives the value of velocities of the moving off stars on several orders less of speed of light . Material falls out of a notion "space". Suppose only the light and gravity field spreads with "c". Suppose that exactly they present the space today. But then it is necessary to find the reason why after BB before forming the material from light this process passed in much limited space - otherwise the empty ballun again. The Light had a velocity close to zero? How the whole material of universe was fitted in unmeasured smaller volume in contrast with existing? What does exists outside the space of universe? The theory does not gives the answer. And one more. Is it not strange that red shift for observer on the Earth exists on all directions without exception. Does it means that all a stars moves off began from the Earth ? Does it means that the Earth is a centre of universe? If no, then why a mutual location of stars does not changes in the current of several millennium of observations? Seems, this a theory does not wants to work.
