I shouldn't be here.... so just one quick post then I must go cook dinner...
Steven, you sure have my brain running 100 mph! I can't go quoting the many points, but one quick question, are you going in the same direction as Good Elf's holographic universe? I have never heard it described the way you have, and I am just stumbling trying to piece it together.
And don't think you are off topic, this is actually the direction I was hoping it would go, you just have gone much deeper than I had expected this topic to be.
I think holographic characteristics arise from uncertainties in communication between two system. Unless you can interact with the entirety of something (which would be a misnoemer as it implies it's already a part of you and invisible as anything externally changing. Instead, it would effectively be part of your internal ruler you use to compare with something else), then you can't witness all possible internal states of it. This leads to multiple internal states having the same outward appearance and this leads to an uncertainty in the durations of the witnessed events, which can be seen as a loss of dimensionality due to the equivalent of a blurring in time between the two (sort of, though very high dimensional structures would likely lose less information in this projection). For example, 3 dimensional communication allows only reliable 2-D representations.
The basic cause of this can be seen to arise from quantization and communication. For example, the least restrictive (most pervasive) and lowest form of 3-D communication is when an object can be seen to exist in one of 3 states. Other methods of communication could be envisioned to lie within 3 dimensions, but they would truly be able to convey information in a higher dimensional context if they allowed for a greater set of symbols/states to be presented. We can just call these states A, B and C (here's a nice equilateral triangle showing both their symmetry and relationship to XYZ coordinates in space):

But as that object changes between states, we can only witness the transitions and not durations of each of these symbols. If we attempt to use our own local clock in an attempt to measure the durations of presentation of each state, then the length of each symbol is determined by local factors (also?), and this can effectively alter the dimensional context of the communication as well (it's now no longer 3 dimensional as additional symbols have been embedded for timing).
So if changes within the object caused an external representation of ABCCBBBA, we would only directly witness the changes of A to B to C but would have no direct way to "see" C repeated twice, nor an ability to see B presented 3 times without some other symbol between them, so the two Cs and three Bs would just be witnessed as 1 of each and the observed sequence would become ABCBA instead. When you look closer you find that for a system conveying n possible states, each observation ends up being witnessed as transitioning to a set of n-1 possible alternatives. Again, you can't witness a transition from one of n possible states to every other possible n states, because a transition to an identical state is undetectable (and would instead rely upon whatever, likely subjective and arbitrary, measurement of time you decided to add to the information, and this would truly increase the dimensionality of the observation in any case as you need access to something conveying that perception of time as well, so I'm trying to sttick to the lowest and likely most pervasive form of communication possible - 3 dimensional).
Now consider that each transition between n symbols conveys n-1 possible alternatives, but these alternatives are relative measurements and don't exist in the absolute terms of the observed system. So effectively it's a translation that doesn't convey things in terms of the true qualities of the original system either.
We could describe transmitting a binary 1 or "yes" or some other arbitrary value as a rotation on an equilateral triangle from A to B or B to C or C back to A, and a complimentary value 0 or "no" etc. as A to C, B to A or C to B. But notice that the these results are no longer related to A, B or C specifically (and they don't directly possess whatever qualities A, B and C represent) but are made in terms of detectable physical contrasts between them. Just as the visible edges of an object aren't related to any specific color but are simply derived from changes in colors or their intensities. Seeing a single color without contrast is the same as seeing nothing at all, just as witnessing something presenting an identical sequence of As is entirely uninformative and incapable of inherently generating any perception of time passing.
Another interesting thing to notice here is that this differential/contrasting measurement between symbols includes a very basic form of memory (as well as a fundamental unit of time). Memory can be used to construct a perception of space. Why don't we perceive all electrons as being identical and the same if their physical properties are identical? How is it that we can separate the detection of one identical thing with another detection of that identical thing? Well, we don't detect them in identical contexts and so differentiate between via. memory. Just as a transition from A to B, is different from the result of a transition from C to B (for example, in this case we might consider B to represent an electron detection, but in one case we might see the electron as having an "up" spin and in the other case a "down" spin. Truly we needn't be detecting a spin property inherent in the electron though, but could instead see this as a separation in space between two alternatives and so you can create units of spacial distance as well and not solely interprete it as detections of various classes of objects. So we could say C represents seeing one location in space and seeing A represents viewing another location and B represents seeing an electron at whatever viewing location we were observing. Then the sequence ABCACB would mean we looked at location A and saw an "up" spin electron, then we looked at C and saw nothing, and then we looked back at A and saw nothing, then we looked back at C and saw a "down" spin electron. In this way the electron "B" could only be seen at location A when it had an "up" spin and at location C when it had a down spin. The location and spin would then be built into the subjective interpretation of space and what represents electrons etc. with nature doing little to force this as the only valid interpretation possible. In this, likely very inaccurate, example, in order to see the electron as existing within various contexts of space we had to attach a spin property to the electron that allowed for its properties to appear different at one location versus another. So we appended a spacial context to its interpretation, which gave it properties related to space and then via. our memory of what exists in space could see more than one electron as existing even though the detection of various "B"s is identical. Another way of seeing how memory, or such relationships to the past, creates a perception of time and space is to imagine a spinning ball. From the surface or interior of the ball, if it existed in a universe all by itself, no perception of time is available as no detectable changes occur from within the ball itself due to its spinning. It takes some external reference to allow this passing of time to be witnessed - so time arises from viewing various changes in relationships between two systems, but it also requires memory as no motion is visible if you can't remember what position the ball was in a moment ago. So a ball may spin but it's only with the additional presence of a memory that can be altered to count, that we could see the ball as having rotated once or twice etc. - time results from the alterations made to that memory)
It's interesting to consider this influence on the attributes or qualities communication. If, for example, (and this may not be very accurate but it's an interesting numerological coincindence) 5 physical senses give a perception of 4 dimensional "spacetime", the original traits and qualities of those 5 senses aren't present in the 4 dimensional representation because it's constructed in terms of contrasts, just as motion isn't directly detectable but only in terms of how it changes relative to energies altering that motion (I see perceptions of motion as arising from information/energy and not the other way around).
So these 5 senses perceive a 4 dimensional spacetime which contains 3 dimensional atoms that are observed as 2 dimensional surfaces constructed as an array of 1 dimensional orbitals (which are 1-D/linear) conveying binary/photonic information over time.
You could see this as the set of ABCDE communicating 4 possible transitions between each symbol (interesting enough this can be interpreted as 2 parallel planes containing single bit information as 2*2=4 - which would mean 2 parallel 3-D systems instead of a single 4th dimension. This jump might be seen as 5 senses viewing 3-D objects in terms of independent position and velocity ... a very interesting possibility)
Anyway, you can see that as each lower dimensional representation is constructed the qualities present in the higher dimensional representation are lost as only the relative contrasts between them are measured, and not the absolutes. So this is why science can't see beyond the physical into conscious realms, though individuals themselves can perceive conscious qualities. It's something inherent in observation and communication.
Now that doesn't necessarily mean everything is alive in the universe as you necessarily have at least one unknown quality present in communication. A rock might exist in some higher dimensional form but we can't observe what it is - it's effectively observing the universe in terms of its own attributes and then giving us its translation in a necessarily lower dimensional representation, so we can't directly witness what "qualities" those higher dimensional attributes of a rock possess, nor can we be certain of the exact timing of events from an absolute perspective but it's still interesting to understand why there's an uncertainty to this and even find logical and mathematical descriptions of it and it's fundamentally based upon measuring contrasts in relative terms.
Another interesting possible numerological correlation is with DNA. The helical rotations of DNA have a 5 fold symmetry conveying 4 symbols composed of 3 dimensional objects composed of 2-D collection of electron orbitals conveying 1-D of binary quanta. From my prior post I stated that knowledge can be seen as provably true and potentially useful when it can predict some event and then correlated this with geometry in terms of looped pathways in space of various lengths performing pattern matching on events. In support of this, it turns out that this matches closely to how DNA itself operates as it performs pattern matching on 4 symbols and bends into various 3-D shapes in loops that depend upon the lengths between these matches. This has already been used to perform real computations in laboratory experiments.
Extrapolating upon this, it makes me wonder if mental processes do represent a 6th sense, but I admit that's not a rigorously tested idea, but on the surface it seems quite possible.
