Primordial Gravitational waves of Half Merging and Splitting Big Bang Black Holes, The Universe we Live in is an Exploded Black Hole..

Primordial Gravitational waves of Half Merging and Splitting Black Holes, before the CMB Cosmic Microwave Background, could be a support for the Cold Black Hole splitting Big Bang forming Herbig Haro BH systems (according Q-FFF model) to morrow by NANOgrav.?

Below: the explosion and evaporation of the Primordial Cold Monster Black Holes from the Big Bang String singularity, into multiple equal sized half merging black holes forming dual Herbig Haro system to form Star /Galaxy systems in between the BHs.
