CONCLUSION:

 

Gravitationally-induced Filament Formation in expanding blobs of gas & dust is common, across the Cosmos, across at least 9 Orders of Magnitude of spatial scale.

WILD SPECULATION:

 

Perhaps the Big Bang was the explosive evaporation of a Hyper-Massive Black Hole (HMBH), of hegemonically gargantuan scale. If so, the Big Bang was not a single, instantaneous event, but rather the culmination of a (very) protracted process. That is, the Big Bang would then be somewhat "smeared out", across many millions of years (Calculations to follow), as the HMBH progressively evaporated.

 

It might, then, even be possible to observe Gradients in the Cosmic Microwave Background, or other physical characteristics of the Cosmos, representing roughly the Radial Vector pointing black to the HMBH remnant. Surely, that remnant, akin to the Crab Nebula Pulsar, is not within our "Level-1 Parallel Univese*" -- to wit, not (yet) w/in our Visible Universe, being more than ~15 billion light-years away, and as yet Causally Disconnected -- for otherwise it would surely dominate the night- & day-time skies.

Calculations for Wild Speculations

 

As derived from Wikipedia, Black Holes, evaporating by Black Hole Radiation, decrease their mass as:

[math]M(t) = M_{0} \left( 1 - \frac{t}{\tau} \right)^{1/3}[/math]

where:

[math]\tau = \frac{5120 \pi G^{2} M_{0}^{3}}{\hbar c^{4}} = 2.1 \times 10^{67} \left( \frac{M_{0}}{M_{\odot}} \right)^{3} years[/math]

Since the Visible Universe has ~1025 (??) MSun of material, our hypothetical Hyper-Massive Black Hole (HMBH) would take ~10140 years to evaporate. Thus, the Big Bang would have been "spread out" over a time-scale of that order of magnitude, literally Googles & Googles of years.
