Quantum FFF Theory says: the entangled Raspberry Multiverse should be the origin of that process.

My Quantum Brain generates only some ideas by itself but is 100 % responsible to VETO them.
According to Benjamin Libet we are only partly responsible for our ideas, but 100% responsible for the VETO process.
The entangled Raspberry Multiverse is the origin of that process. https://bigbang-entanglement.blogspot.com/2019/06/my-quantum-brain-generates-only-some.html
However the whole Quantum Multiverse seems to be subjected to Charge Parity symmetric entanglement, even for single particle interference in double slit systems.
