However, he did not accept that Fermions are mostly based on compounded transformable massless strings resulting in different Fermion masses.
So only the electron and the positron as single rotating propeller strings have mass.( in Q-FFF Theory)
Massive Quarks are all compound String structures (in Q-FFF theory) based on at least one electron or positron compounded with one or more photons.

So Gravity is a dual opposing Quantum Force, like all other forces ( Magnetic fields and Electric fields)

The New Physics of the combined Penrose- Libet-Cramer-Q-FFF Model, is opposing the standard model of physics.
Q-FFF theory proposes the creation of Massive (Entangled by Cramers TI, Transactional Interpretation) Fermion Pairs out of the Oscillating Virtual String Vacuum (Collider Black Hole Horizon( Q-FFF model) by the "Penrose Trapped Space Horizon" around all Black Holes.
This new physics black hole is by the Q-FFF model interpreted as "Virtual Axion String Space Collider Horizon producing real Fermions", even around Ball Lightning Micro Black Holes.
However we need a 12 fold (anti) Copy Multiverse to be able to use the Benjamin Libet process of two different "Readiness Potenrials" ( RPI and RPII) for a democratic system of Free Won't in the John Cramer's instant transactional Multivers.
