The Big Bang was the Splitting and Explosion of the Former Big Crunch Dark Matter Black Holes into Herbig Haro systems for starformation.

In contrast with standard physics, Black holes are String Knots compacted and compressed by the oscillating Axion-Higgs vacuum space frame or spacetime.

Roger Penrose suggested that each Black Hole has a trapped Spacetime Horizon like a proton collider (LHC) creating new fermions out of the vacuum strings.

This means that all Axions are primary particles able to form other particles.
