Is it possible that instead of one big bang originating from one singularity there were a number of them in different positions? The reason being the requirement of symmetry. How would the individual big bangs 'know' of each other without c? This question would be answered by quantum 'spookieness' as Einstein described it.... If the big bangs already know of each other without even being connected through c, then you could say that the multiple big bangs occured as one big bang because they knew of each other simultaneously even though they were distances apart.
