Where the early fluctuations of the CMB come from? Q-FFF model says:
1: by the new physics Black Hole spitting and splitting BIG BANG, creating Herbig Haro new stars between two equal sized black holes.
Why the universe has a Flatnes density of matter and energy?
1: By the contracting Virtual string Planck space frame vacuum of the Q-FFF Theory into growing black holes to form a big Crunch Black Hole Singularity.
