Light, vision and human consciousness
Photons bring us the past. Information from the past is locked
into photons. We can even look at what the universe was billions
of years ago. Our capacity to see is closely related to
consciousness and consciousness is closely related to light (or
to the information contained within it).
What role does light (EMR) plays in determining Schrodinger's cat
state (dead or alive)? Is it light itself the only important factor
closing the loop, or, is it the observer's conscious acknowledgement
which causes the final determination of the cat's fate? In other
words, is the wave packet collapse a function defined by the
structures of matter, a result from the interactions and relationships
of its parts, independent from human observers, or, is state vector
reduction a function of mind?
The answer is 'yes' to both questions, there is no contradiction, it
is the function of self-observation and organization intrinsic to any
self-organized system. Take neutrons for example, how can a neutron
maintain its geometrical configuration during millions of years
without flying apart? How does syntropy come about?
The medium in which any given self-organized system is developing is
full of information which the system will use to maintain itself.
Matter is not different, it can be defined as a self-organized system,
and the medium in which it develops is full of information in the form
of EMR. Any given neutron will need to extract from hyperspace only
that information which it needs to support its structure. The fact
that this information comes from hyperspace allows it to be a
non-local function which has been defined by Bohm's quantum potential
as a holistic awareness function of matter, as he explained EPR type
phenomena.
Now, after billions of years, this information exchange between matter
and the environment in which it evolves has produced ever more complex
(information engenders information) self-organized systems, like human
beings, for example, who have evolved to take full advantage of these
holistic awareness function of Nature, which is what enables them to
think. So thought is the same holistic awareness function with which
matter started organizing itself billions of years ago.
Is this proof, however, that there exists in Nature some syntropic
force, an energy analogous to information which will try at any
opportunity to beat entropy, constantly creating order out of chaos?
Evolution is a very slow ratchet-like motion, where nature selects and
locks-in any advantageous randomly occurring changes. These are
property based selections where the favored properties are usually the
ones which will lead to increased thermal efficiency, and that is
going against entropy already.
More important than backaction I think would be the ability of a given
system to perceive itself all at once, that's when quantum
communication and computation come into play. Quantum consciousness
came later, with brains.
Awareness is a secondary function of matter which enabled Nature to
evolve. Consciousness, thanks to this function, is what enables us to
think and exist in 4D, in a continuum unbounded from causality (or
linear time). And that makes Bohm correct when he says state vector
reduction occurs thanks to this 'wholeness in space' function of
matter, consciousness is 'wholeness in time'.
There is a spherical, inwardly collapsing, standing wave caused by our
brains, but why call it God, or even Cosmic Consciousness? Why not
just call it for what it is - human consciousness?
The Universe exists because of active information contained in all
kinds of interacting waves, and if it wasn't for wave superposition,
there would be no Universe. Thanks to the parallel and non-linear
information processing mechanisms inherent to waves there can be
information growth.
Human consciousness is the ultimate product of a natural, energy
balancing mechanism, determined and regulated by the laws of
thermodynamics. Each object's energetic requirements has to be
measured before entering any given spacetime metric, before going
from its subtle quantum matter state, or wave state, to its objective
material state, or particle state. These information requirements are
met through wave interactions, and the mechanisms governing wave
superposition as described by the science of wave harmonics. Timothy
Boyer termed this energy balancing radiation 'equilibrium spectrum',
others call it Unruh-Davies radiation.
EMR was and still is the main means of information propagation and
natural communication between spacially separated objects, and within
objects. Already existing information leads to the creation of more
information. Information can only exist in a material form. Biological
organisms evolved to use light to their benefit very slowly. As we
already know, it took them billions of years (pre-Cambrian to
Cambrian) just to develop eyesight.
Brains are these little bio-mechanical tools that emerged with
evolution for the only purpose of enabling us to interpret and
interface with reality. Since what happens is really governed by the
laws of thermodynamics, as spacetime tends towards equilibrium,
through a process of natural selection, matter improved its ability
to observe and perceive the environment and evolved into brains
that could take advantage of the properties of spacetime. Brains
exists only because there is spacetime.
Nature would still be able to exist and observe itself even without
the human observer, it would just be a more primitive process. Our
brains are Nature's best developed self-observational tool.
Experience is fundamental to existence, but it is not reality
(Berkeley was wrong). Reality is the process through which Nature is
constantly becoming. Our consciousness (as it manifests in our human
existence) is an extension of the same holistic awareness function
that self-organized matter always utilized to observe itself, therefore
human consciousness is still - Nature observing itself.
As Roger Penrose explained quasicrystal development in his book "The
Emperor's New Mind" (p. 564), he writes that it appears as if the
whole crystal is 'observing' itself (each present atom configuration
pattern is embedded into its pilot-wave) and choosing from qualia,
using some holistic awareness mechanism by which they can compare
present qualia to past qualia and all the possible rock-like outcomes,
all at once, and which are limited by the system's tendencies or
potentialities, until the right atom configurations are found while
constructing their "randomly forbidden, very complex, icosahedral
symmetries".
Experience plays an important role in the correct development of the
crystals (as well as in all self-organized systems). The crystals
accomplish their self-observation by following information contained
in their pilot-wave (Bohm-de Broglie), which contains past (and even
future) information about the crystal, as a whole. Proto-qualia for a
quasicrystal would be how all the possible atom configurations would
'feel like' as they remain in superposition until a good one is selected,
and only then could the collapse of the wave packet finally occur.
From the moment the first self-organizing systems appeared in Nature
to the moment the first human brain appeared it's being a few billion
years, but in both occasions the objective has been the same; to
experience existence. Penrose's quasicrystals don't have a brain, but
they follow their state wave function as the measure by which they
must exist, and if by any reason they were to stop following their
state wave function as they add new atoms to their body, they would
end up becoming a totally different type of material. The objective
state a human being follows (or should I say - the measure by which
a human being exists) is defined by its brain state wave function.

Superradiance within the brain I think is a very promising concept
when trying to understand consciousness.
This is from Hameroff's website:
" Another candidate for the Cambrian emergence of Orch OR
consciousness involves the evolution of visual photoreceptors.
Amoeba respond to light by diffuse sol-gel alteration of their actin
cytoskeleton (Cronly-Dillon and Gregory, 1991). Euglena and other
single cell organisms have localized "eye spots" e.g. regions at the
root of the microtubule-based flagellum. Cytoplasm may focus
incident light toward the eye spots and pigment material shields
certain angles to provide directional light detection (e.g. Insinna,
this volume). Euglena swim either toward or away from light by
flagellar motion. Having no neurons or synapses, the single cell
euglena's photic response (sensory, perceptive and motor
components) depend on MT-cytoskeletal structures.
Mammalian cells including our own can respond to light.
Albrecht-Buehler (e.g. 1994) showed that single fibroblast cells
move toward red/infra-red light by utilizing their MT-based centrioles
for directional detection and guidance ("cellular vision"); he also
points out that centrioles are ideally designed photodetectors. "
" Jibu et al (1994; 1996) have predicted that cellular vision depends
on a quantum state of ordered water in MT inner cores.
They postulate a nonlinear quantum optical effect termed
"superradiance" conveying evanescent photons by a process of
"self-induced transparency" (the optical analogue of
superconductivity).
Hagan (1995) has observed that cellular vision provided an
evolutionary advantage for single cell organisms with cilia,
centrioles or flagella capable of quantum coherence.
In simple multicellular organisms, eyes and visual systems began
with groups of differentiated light-sensitive ciliated cells which
formed primitive "eye cups" (up to 100 photoreceptor cells) in many
phyla including flatworms, annelid worms, molluscs, crustacea,
echinoderms and chordates (our original evolutionary branch
Cronly-Dillon and Gregory, 1991). The retinas in our eyes today
include over 108 rod and cone photoreceptors each comprised of an
inner and outer segment connected by a ciliated stalk. As each
cilium is comprised of about 300,000 tubulins, our retinas contain
about 3 x 1013 tubulins per eye. (Retinal rods, cones and glia are
interconnected by gap junctions - Leibovic, 1990.) Conventional
vision science assumes the cilium is purely structural, but the
centriole/cilium/flagella MT structure which Albrecht-Buehler has
analyzed as an ideal directional photoreceptor may detect or guide
photons in eye spots of single cells, primitive eye cups in early
multicellular organisms, and rods and cones in our retinas. Quantum
coherence leading to consciousness could have emerged in sheets of
gap junction-connected ciliated cells in eye cups of early Cambrian
worms. "
