- Are SSFRs really SFRs associated with the edges of the space-time surface or does their sequence define a TGD finite counterpart of Feynman path integral so that no decoherence would occur?
- There are also questions related to the details of the periods consisting of SSFRs. The increase of the size of causal diamond (CD) by scalings occurring in SSFRs would allow us to understand how subjective a sequence of SSFRs corresponds to geometric time as distance between the tips of CD.
The alternative proposal is that CD shifts gradually to the direction of the active boundary of CD at which the states do not remain fixed in SSFRs. Which option is correct? Does the size of the CD increase indefinitely or does it reduce in BSFRs so that conscious entities would experience childhood after every BSFR? Is the breaking of T symmetry (and also CP symmetry) necessary for the gradual shift of CD to a fixed time direction?
- The feed of metabolic energy is necessary for consciousness. Sleep and wakeup can be identified as conscious states with opposite arrows of geometric time. Does the periodically varying feed of the metabolic energy from the Sun as light ,making also possible direct visual perceptions, give rise to a stochastic resonance in which the state of consciousness corresponds to flips between the potential wells of a bistable system.
