The expansion of the BB singularity?

Question

I will start by saying that I have relatively no training in the area of physics...though science fascinates me (if advanced mathematics was not such a black hole for me, I suspect my career path would have been one of the natural sciences).

Anyway, that is what it is.  I was, however, doing a bit of a thought experiment (something I sometimes enjoy) regarding the singularity.  My question is this:

Since we 1) basically know that the big bang was a hyper-rapid expansion rather than a "bang" (semantics perhaps, I agree) and 2) entropy seems to be the only true barometer of " what we know defines time", does new physics think that the big bang was caused by either:

- the singularity expanding simply because it was "new" and  - for lack of a better term - it was its "purpose"

or

2) the singularity expanded because the force that was holding it "in" (i.e. making it the singularity what it was) was overcome by the force the singularity exerted upon it to expand.

In other words, did the singularity have to overcome another force to expand, or did it simply expand without counteracting an opposing force holding it together?

I thank you all in advance for entertaining - and giving your thoughts on - my little thought process.

The primordial event did not expand because it was new nor did it develop uniformly either because it was a blast. Both have ambiguous conclusions. The expansion, as it relates to the BB, was due to hot matter seeking cooler regions. The old "path of least resistance" principle comes to mind. The problem is the BB is an aging theory with dwindling capacity to amend itself. To cling to the security of such an old theory reduces the mind's ability for growth. It stubbornly refuses to offer a smooth explanation for expansion, instead opting to accept it like an adopted child. Next, if the BB were the final authority, there would be wavelength differences at the edges of galaxies as the energy is 'shadowed' on its way to Earth. This is not the case. Also, there is no center nor edge. Thus, a blast radius is preposterous. The best adaptive theory is yet to come.

EDIT: Of what I've read, data from the WMAP doesn't contradict the laws of Thermodynamics operating in their usual sense at the fringe of the 'last scattering surface' where the gas cooled enough to form visible light. Inside the walls of the scattering, anything is possible in the range of the Planck temperature where the four forces join. A new probe (Planck) was launched this May to continue the research done by WMAP with better instruments. A lot remains to be seen, but my guess is it will be a slow paradigm shift into a new theory.

I think it counteracted something, if it didn't have to why didn't it just expand long before it did 13-15 billion years ago?
