Abstract
Theory of everything must include consciousness. In this article, we focus on
introducing the subjective experience (SE) aspect of consciousness in modern quantum
physics, namely, loop quantum gravity (LQG) and string theory by using the
methodology of examining invariance of these theories under the PE‐SE
transformations, where PEs (proto‐experiences) are precursors of SEs. In our dualaspect‐
dual‐mode PE‐SE framework, (i) each of strings, loops, elementary particles,
inert matter, or neural‐networks has physical (material) and mental aspects, and (ii)
there are three competing hypotheses: superposition based H1, superposition‐thenintegration
H2, and integration based H3 as discussed in Part I. In Part I and Part II of
this series of 3 articles, we introduced the SE aspect of consciousness in classical and
orthodox quantum physics, respectively, which are invariant under PE‐SE
transformations. In the current Part III, the critical components of LQG with Palatini
action appear invariant under this transformation. In string theory, for H1 and H2, we
quantitatively introduce the superposition of potential experiences (SEs/PEs) in the
mental aspect of bosonic and fermionic strings using the Polyakov action. We find that
experiences are independent of the time‐like and space‐like parameters (τ, σ). This is
interpreted as a string is a dual‐aspect entity and all fundamental potential SEs/PEs that
are superposed in the mental aspect of the string remain invariant with time and
space. The introduction of mental aspect in this manner suggests that the mental
aspect of string could be in all dimensions: both (3+1)D real dimensions and also in the
hidden dimensions that are compactified (curled up). In addition, the Neumann and
Dirichlet boundary conditions were also satisfied. These led us to conclude that the
physical aspect of the behavior of system in string theory remains invariant under the
introduction of experiences aspect of consciousness in the mental aspect of strings. For
hypothesis H3, the equations of string theory remain the same as they are; we simply
need to acknowledge that a string has dual‐aspect; its mental aspect is string‐PE.
Furthermore, if the introduction of SE aspect of consciousness in string theory is
interpreted to imply that experiences are independent of time and space in all
dimensions, it may not be true in conscious beings. This is because SEs change with
subjects across space and time. This fact is revealed in the introduction of SE aspect of
consciousness in general theory of relativity of classical physics: (i) For the structure of
spacetime (empty space or the vacuum without matter), potential SEs are superposed
in the mental aspect of spacetime and are embedded in spacetime geometry. (ii) For
matter field, potential SEs/PEs are superposed in the mental aspect of each elementary
particle (fermion or boson including graviton); wherever these particles move,
superposed potential SEs/PEs must also move with them to conserve the superposed potential SEs/PEs. (iii) However, since our specific SE is the result of matching and
selection processes that actualize/realize the relevant potential SE, the SE can change
with space and time. For example, the neural correlate/analog of experiencing redness
is V4/V8/VO‐red‐green neural‐net with redness state. When a subject moves, the
specific SE redness also moves with the subject’s correlated neural‐net. SEs also change
with time as stimuli change. In other words, SEs in a subject change with spacetime. We
conclude that it is possible to unify SEs/PEs aspect of consciousness with all four
fundamental physical forces by the introduction of (i) potential SEs/PEs (as in H1) or PEs
(as in H2) in latent superposed form in the mental aspect of bosonic and fermionic
strings or (ii) the bosonic‐string‐PE and fermionic‐string‐PE based on integration
principle (as in H3). This leads us towards the theory of everything.
