Ever read something that sticks in your mind and you can't get rid of it ?
Well, this is mine for the week … I've been pondering this one for some time now. (I warn most .. this is a bit of a brain-bender and it is purely theory-related).
It all started with this article:
Researchers show that the big bang was followed by chaos
Its a difficult article to understand, but basically some theoretical researchers have demonstrated mathematically, that highly chaotic behaviour immediately following the big bang is a perfectly valid assumption. The term 'chaos' is used in the mathematical theoretical sense ala
Chaos Theory.

The present-day universe is expanding and does so in all directions, Motter explained, leading to red shift of distant light sources in all three dimensions -- the optical analog of the low pitch in a moving siren. The early universe, on the other hand, expanded in only two dimensions and contracted in the third dimension.

Translated loosely, that means that mathematically, they have shown that initially after the Big Bang, the Universe wobbled like a blob of jelly … the top got short while the sides blew out, then the sides contracted and the top balloned, etc.' That would seem to be obvious but, so what ?, what does this mean ? why is it important ?
That's where it starts to get interesting .. apparently, for 22 years the 'chaos' premise has
not been obvious, nor agreed (for sound General Relativistic reasons). So, now that it is clear, what does this mean ?
I think what this 'discovery' means is that cosmological evolution models, (post Big Bang), now have been given a firm foothold to go forward and fill in the details of how Large Scale Structure, (galaxies, super galaxies and upwards), evolved to where it is today. I also think that they can now start to more firmly relate things like present day Sky Surveys and mappings, to the WMAP CMBR data, and begin to explain with firm foundations, why large scale structures are where they are today, along with their general shapes.
Also, it shows that the common view that closer to, or at the time of Big Bang, things were too hot and chaotic for present day Physics to hold, is not necessarily so. There may be some present day things, like mathematically describable chaotic behaviour, which are now shown to be perfectly valid at the very outset of the Universe, despite the unimaginable conditions at that time.
If my thinking is correct on this, this is a major step forward and shouldn't go unrecognised.
