Nuts to the Big Bang

Has it occurred to anyone that an outwards, spherical in shape explosion, or the Big Bang singularity is not the most obvious model?<>
Would not two jets of particles (of any size and/or composition) ejected outwards in opposite directions, i.e. the streams of matter at the center of galaxies, answer a few of the questions posed, but not answered by the Big Bang Theory?
Such as: Why is the universe so uniform on a large scale? What was the origin of density fluctuations in some areas of the universe? And what caused the critical rate of expansion so the universe would not re-collapse seconds after the singularity?
