According to Quantum FFF Theory. (FFF= Function Follows Form at the quantum scale),
singular rigid transformable string based Axion Higgs (AH) particles are the content and origin of the symmetrical splitting big bang into chunks of AH particles (Dark Matter black holes) able to evaporate into smaller chunks and singular AH particles building the flux tube based chiral vacuum lattice. (Dark Energy).
Colliding A-H particles specially at black hole horizons create pairs of Fermions called "production production"
AH particles create photons and gravitons by a collision process with propeller shaped spinning Fermion of different complexity of design and different masses.

Quotation: In the big bang, "The axion mattress ( the vacuum) was extremely compressed, which made the Higgs mass enormous. As the universe expanded, the springs relaxed, as if their energy were spreading through the springs of the newly created space"
