Alex,
Reference to Big Bang Cosmology will tell you that universe is expanding or stretching.
Both these words 'expanding' and 'stretching' can give different meaning. For example take an urban cluster, build more buildings on the outskirts and the city has expanded (no stretch), on the other hand take a rubber band stretch it, it has expanded as well as stretched.
What is BB's expansion and stretch, is it like addition of new buildings or is it like rubber band stretch or something else? When we observe redshifts, the prevalent explanation suggests that it is kind of rubber band stretch (increase of intervening space).
In the proposed idea say space or CQF or nothingness was infinitely spread in rest state. No particle, no motion, no change, no observer and nothing to observe. Under such circumstances it is not incomprehensible that time was non existent till something happened and this CQF started lumping (could be at multiple places), this lumping caused stretching in CQF.
The idea is in total contrast with origin from a BB singularity. Some discomfort with the BB singularity which this proposal eliminates
1. Singularity was very densed, obviously made up of matter. It does not explain formation of matter as such. It proposes (in my understanding) that matter was already there compressed in this singularity.
2. Huge temperature and pressure was present at that time. Where did temperature and pressure come from? Singularity could have had any mass, but at the end of the day it was a point (not grainy), so again (in my understanding) assigning any thermodynamic property like temperature to a single point like entity (with no space to move around) is too much of an assumption.
3. We still do not know why should it come out of singular state. Well it is hypothesized as spacetime singularity, but you know temperature / density / pressure is associated with it. It is taking for granted that all three properties existed at t = 0+.
4. And then we have almost impossible natured expansion, called inflation. Associated Physics of inflation is an issue even today in mainstream. No doubt it resolves certain issues around original BB hypo.
5. And then we have quark gluon plazma, as stated earlier it assumes presence of matter.
