How far away is your parallel self? (New Scientist, 18-Jan.2017)
Quantum FFF Theory tells us the need for a distant parallel self to become conscious in the quantum universe, called:
Democratic Free Will and Telepathy in the Instant Entangled Multiverse.
"Benjamin Libet measured the so called electric Readiness Potential (RP) time to perform a volitional act, in the brains of his students and the time of conscious awareness (TCA) of that act, which appeared to come 500 m.sec behind the RP.
The “volitional act” was in principle based on the free choice to press an electric switch button.
The results of this experiment gives still an ongoing debate in the broad layers of the scientific community, because the results are still (also in recent experiments) in firm contrast with the expected idea of Free Will and causality.
However I would propose the absurd but constructive possibility that we are not alone for decision making in a multiverse as an individual person.
Even Max Tegmark suggested already about the multiverse: “Is there a copy of you reading this article?”"
