According to the Quantum FFF Theory conjecture, we live inside one of a specific number of Charge Parity symmetric copy universes coming out of a huge Axion/Higgs rigid string black hole nucleus explosion. Exploding into (1) Chunks of Primordial Dark Matter Black Hole (Primordial black holes) and (2) into the oscillating Axion/Higgs field string flux-vacuum by black hole evaporation.
However, In the short inflation era not all “Empty Space” can seemingly be filled at once , see image below, which seems to be the origin of several blind spots found in the early universe.

Black holes EAT the Axion/Higgs field oscillating dark energy vacuum lattice,
However In the early inflation this vacuum lattice seems to have holes between the Lyman Alpha forest.
