The explosion that resulted from the big bang was unique, not just for the obvious reasons, but also because: a) it was an explosion of pure energy… matter came much later. And b) there was no medium for it to expand into… the envelope of the explosion defined the outer limits of the new universe.

So, my question is: Why is the observed homogeneity of the universe such a problem to the standard model? When astronomers and cosmologists say that the big bang should have created more ‘blobbiness’, could this be because they are making assumptions about the big bang based on mathematical modeling of conventional explosions?

Is it possible for example, with the energy quanta all having the same charge, that an expansion based on mutual repulsion might have caused the homogeneous universe we observe?

The big bang was NOT an explosion. It was an expansion of everything... of spacetime itself. Treating it as an explosion will lead you to a lot of confusion.

OK, explosion/expansion... this is just semantics.

My question remains, that is it possible that the fault lies in assumptions about the nature of this expansion, namely that it should produce a lumpier universe than the one we observe; rather than with the Standard Model itself?
