It is reasonably expected 1) that a theory of quantum gravity will unify the extremes of scale currently described by General Relativity and quantum mechanics, and 2) that black holes are the crucible from which a theory of quantum gravity will emerge. In perspective, we already have a mechanism that links the local, macroscopic frame with the remote, apparently microscopic frame. A simple mathematical principle acts as a limit on D(n), suggesting a “maximum physical reality”, and that effects which are clearly perspectival at D=3 become “more real” (effectively observer-independent) with each D(n) increment. The model suggests alternative interpretations of gravitation and the quantum, entanglement, space, the Standard Model of particles and interactions, black holes, the measurement problem and the information paradox.

1. Introduction

Profound conceptual incompatibilities exist between General Relativity (GR) and quantum mechanics (QM) as currently formulated. For instance; 1) whereas in GR, time is just another covariantly transforming coordinate of an arbitrarily differentiable spacetime manifold, in QM it is an external, Newtonian parameter and properties are discrete, and 2) the respective macroscopic and microscopic domains of applicability remain as disconnected as ever. The paper proposes perspective at as a possible means of unification. A simple mathematical principle is then invoked as a natural limit on and the implied existence of a “maximum physical reality” therefore means that effects that are clearly perspectival at must become “more real” (effectively observer-independent) with each increment. (The apparently microscopic thus becomes the effectively microscopic, and 3-space scale extremes are juxtaposed.) Characteristics of the relationship between the earth- bound observer and the horizon are applied to, suggesting perspectival interpretations of space, universal expansion, radiation, entanglement, gravitation, mass, dimensional reduction and measurement (as projection rather than amplification). The difference between apparent flatness of the 2-surface and actual global closure corresponds to the boson of the gauge interpretation (i.e., the observer’s height, projected from the local, macroscopic frame to the remote, effectively microscopic frame, where it appears as a “collapse vector”). Although horizons therefore appear to radiate, a Hawking photon is instead thought of as a “unit of projection” (of the local frame to the remote), thus challenging the notion that photons “travel through space”.

The paper is structured as follows. Section 2 considers the natural limit on and its implications. The main geometrical characteristics of are outlined in Section 3, including a duality of the fundamental constants of GR and QM (i.e., and). Section 4 interprets perspective as gauge, and Section 5 then interprets the Standard Model gauge group as perspective, with gravity included by way of charge- mass duality. Characteristics from Section 3 are then applied to black holes in Section 6 using an Alice-and-Bob scenario. A scheme for quantum gravity (QG) is outlined, together with an account of black hole entropy and an interpretation of the information paradox as a perspectival effect. Finally, Section 7 is a discussion and brief

summary of the main ideas. In terms of notation, the case in which a surface is spherically closed and embedded in is denoted typically as.

2. Natural Limit on D(n)

If differences are now expressed as derivatives, then the difference between two spacetime positions and is a change of position or velocity, and the difference between two velocities is an acceleration, etc. At each iteration, the previously established difference is used as a new reference, and the de-

Diminishing Freedoms

Since the observer also possesses limited freedoms, perspectival effects at (e.g., geometry, horizons) become increasingly observer-independent with each increment with respect to the observer; i.e., the

observer possesses diminishing freedoms with respect to physical phenomena. Therefore we define dimensionality in terms of freedoms. Whereas in the observer possesses the freedom to orientate in any superposition

of axes, in the observer has limited freedom to orientate in 4-space in axes ^{1}, and in

, freedom is further curtailed; a body now has mass (i.e., is subject to spacetime curvature). Similarly for horizons; at the planetary horizon is global (remote), surrounds the observer, and is completely observer-dependent, moving as the observer changes 2-position (i.e., is totally “permeable”). At the cosmological horizon is also global (remote) and surrounds the observer, but is less observer-dependent, moving as the observer changes 3-position (i.e., with the observer’s velocity) but being causally “semi-permeable”. Finally, at, massive bodies are now subject to local (multiple) black hole horizons which do not surround the observer (rather, it is as though a remote, global horizon has been brought into the local frame, in some sense). The event horizon is now a strictly one-way membrane with unclear observer-dependent status; one would expect it to accelerate with the observer. (The Rindler horizon, with similar thermal properties, appears at constant 3-distance for constant acceleration.)

3. Geometrical Characteristics

Perspective in 3-space is that effect whereby a receding object appears to shrink to an apparent point. Perspective plus curvature (e.g., on the closed surface of Earth) means that the size of the object does not go to zero before the object disappears over the horizon. At, using metres as units, Alice stands with 3-height above the 2-surface, which is closed with constant radius of curvature. More formally,

we specify a manifold that is closed with constant radius of curvature and embedded in according to the Nash theorems. At we define a 3-height and a tangent space bounded at a constant distance from x by, where. The manifold is bounded by, where at a distance along such that, where is coincident with the “top” of

. The tangent space is defined as the perception of due to in the frame of an observer located at x with. We note the following characteristics.

1) Assuming, the 2-surface looks flat to good approximation (Figure 2(a)).

2) There is an increasing divergence between apparent flatness and actual global closure (Figure 2(b)).

3) Parallel lines on the surface (e.g., railway lines) appear to converge to an apparent D0 point or singularity on the horizon (at a distance).

4) With increasing distance from Alice, objects appear to contract and space appears to expand, and Alice reasons that these rates must be exactly equivalent;.

5) There is a dimensional reduction from Alice’s 3-height to an apparent D0 point on.

Figure 2. The familiar geometry of the earthbound scenario.

6) There are two such points; A, where Alice (naively) believes she is looking, and B, where she is actually looking. In 3-space, these are clearly the same point; A and B are identified.

7) If Alice gains sufficient 3-height, she will see the D0 point singularity transform or open up to become a D1 line singularity (i.e., there is a non-zero separation, , between railway lines as they disappear over the horizon). This forced transition, , acts as a gate that reveals the embedding of in (i.e., the case).

8) The difference between apparent flatness and actual global closure is just Alice’s local 3-height, projected (and rotated through) to the remote, horizon. (Alice’s apparent 3-height, as projected to the remote frame and seen from the local frame, is less than the thickness of the average human hair;.)

9) The angle subtended at Alice’s eye between the true horizontal line of sight (i.e., tangential at a radius of) and a line of sight to the actual horizon is necessarily equal to that subtended at the centre of the Earth between radial lines to the locations of Alice and the horizon, so the relationship (and transition) between points A and B is proportional to and associated with those between the local observer and the remote horizon.

10) The transition is also that from triangle (1) with, to triangle (2), with, so the transition is associated with the loss of the term.

11) Observer-dependency of the S^{1} horizon can be expressed as the fact that 2-distance to the S^{1} horizon is a constant in every frame.

12) The of an object that disappears over does not cease to exist but is “conserved” in 3-space.

At, Alice’s 4-height is taken to be velocity (rather than the Minkowski spacetime interval,). Assuming, the 3-surface “looks flat”, but due to the existence of, the apparent velocity of Bob, receding, “contracts” with 3-distance to some irreducible value, interpreted here as a minimum energy,. However, when Bob is at, his velocity relative to Alice is, and so the curvature limits are the characteristic GR and QM constants, and. At

the linear expansion of spacetime with increasing 3-distance from Alice corresponds to universal expansion with constant velocity [1] [2] . We also note that observer-dependency of the S^{2} (cosmological) horizon can be expressed in terms of the fact that 3-distance to the S^{2} horizon is a constant in every frame.

At, Alice’s 5-height is acceleration. Assuming, the 4-surface “feels flat”; i.e., implying a physical basis for, as required by the Equivalence Principle (EP), but due to the existence of, the apparent acceleration of Bob, falling towards the black hole event horizon, decreases with 4-distance to some irreducible value, interpreted here as a minimum acceleration,. At the same time, Bob’s acceleration relative to Alice is, where is an effective maximum beyond which the Unruh or Hawking radiation wavelength is (i.e., a firewall) and so the curvature limits are and. At, the second-order expansion of spacetime with increasing 3-distance corresponds to accelerating universal expansion [3] [4] . We also note that observer-dependency of the S^{3} (black hole) horizon can be expressed as the fact that 4-distance (v = c) to the S^{3} horizon is a constant in every frame. Thus the fixed 4-distance to theblack hole event horizon in the local, macroscopic frame is the quantum of energy in the remote, effectively microscopic frame. In this sense, then, ^{2}.

4. Perspective as Gauge

Alice and Bob are astronauts moving away from each other in empty space, and, for the purposes of this consideration, we assume that neither has any prior spatial understanding. Alice first notes that Bob appears to be shrinking. Since they disagree on who is shrinking, they each theorise the existence of an embedding 3-space that makes sense of the fact that, with increasing distance, objects appear to contract (CON) and space appears to expand (EXP). Now as observers on Earth (but still without any geometrical understanding) Alice and Bob stand with equal 3-height above the 2-surface, which is closed with constant radius of curvature. Alice is directly aware of the existence of the 2-space, but has to infer (e.g., using parallax) the existence of a higher, 3-space. Assuming, the 2-surface looks flat, so Alice does not recognise as an horizon, but merely as a “dimensional separation”. Therefore the significance of 3-height (or potential) and its relation to the horizon remains unacknowledged. In other words, Alice does not recognise Earth as an object.

However, from outside her frame, we can see that the difference in her frame between apparent flatness and actual global closure is just the potential, projected (and rotated through) to the remote horizon, represented by the “collapse” vector R in Figure 2(b). Now Alice and Bob disagree about shrinkage and phase, which vary from point to point. In gauge terms, the 2-surface is the base space, and the unacknowledged potential is the fibre, defining an internal space at each point on which together comprise a fibre bundle, , such that. The gauge field comprises gauge connections that correspond to the group of continuous symmetries of, and in that there is a canonical projection, submersion or surjective map, , then the phase is a continuous image of in. Thus, R is just the potential, projected from the local to the remote frame, that appears in Alice’s frame as a “minimum unit” (i.e., the gauge boson or field quantum) that is the coupling constant or interaction strength that translates between frames and restores local gauge

invariance. Alice also notes that as she and Bob stand at each other’s horizon, the values 2 and define curvature limits at, allowing this geometry to be applied to.

5. Gauge as Perspective

The Standard Model (SM) is the non-Abelian gauge group that describes particles and interactions in terms of a sequence of early-epoch phase transitions following a Big Bang at. In the perspective approach, the SM comprises two groups of sets of perspective reductions. The first is, where are derivatives,. These generate apparent Planck dimension perspectival convergence limits (with), which are interpreted as fermions. At each level, a height is associated with spherical closure of, forming a series of “onion layers”, where each closure generates -forms that populate space; (i.e., a string), etc, as depicted in Figure 3. The second group is, generating apparent D2 area singularities that live on the horizon separating, interpreted as the leptons, the 2-forms that in the SM are “cousins” to quarks.

Assuming at each level, each surface can be described as a state defined by n direc-

tions or generators, so each lower level can be thought of as a state-splitting or copying process producing families of generations; e.g., the Cabibbo-Kobayashi-Maskawa matrix describing expectation-values for transitions between families and generations of quarks (with the Cabibbo angle corresponding to probabilities of decay modes), and the Pontecorvo-Maki-Nakagawa-Sakata matrix summarising weightings for lepton-mixing. The superpositions of directions (generators) at higher are rotations that transform lower particles, as depicted in Figure 4.

Figure 3. Two groups of reductions generate an “onion-layer” model of particles and interactions, and juxtapose quarks and leptons (dashed line).

Figure 4. directions are particles at, and IVBs at are fermionic generations at. In this progression, space at becomes a fermion at.

Each inter-dimension or phase transition is a perspective reduction; at each level, a -form possesses a local height (a property defined by that internal space), from which there is an apparent diminishing of until it disappears over the associated horizon. Thus, colour bleaches

out of Quark-world as quarks “fall into Quark-world black holes” (i.e., inside-out hadrons), which is the process of baryogenesis, marking the global closure of D2, the formation of colour-neutral baryons and the conservation of colour. Likewise, charge bleaches out of Nucleus-world as “nuclei fall into Nucleus-world black holes” (i.e., electrons, or inside-out atoms), corresponding to the formation of charge-neutral atoms and the conservation of charge at global closure of D4. In the perspective model at, information bleaches out of the (D4) universe as an SM phase transition. In QED, the atomic nucleus containing positively charged protons is sur-

rounded and perfectly balanced by shells populated by negatively charged electrons;. The 5-height of

the nucleus connects via D(n − 3) perspective reduction to a Dirac spinor of the Penrose zigzag electron, [5] in the last electron shell. In the nucleus frame, assuming, the separation of equally spaced calibrations of the n-surface appears to decrease with increasing distance and so the exact location of the horizon is uncertain, and electron shells are thus interpreted as multiple horizons. The quantum state

of the atom is defined as a superposition of all shells, or, in which are the eigenstates of an observable (e.g., the principle quantum number, n) corresponding to eigenvalues.

Electromagnetism-Gravitation Duality

Given the correspondence between at the macroscopic level and at the microscopic level, we now ask if there is a precedent for the notion of charge at the macroscopic scale. We note that mass tends towards horizons; either expanding (state; EXP) as part of the Hubble flow towards the cosmological horizon, or contracting (state; CON) towards black hole event horizons (Figure 5). In Alice’s frame, the rates

must be exactly equal;. Such labelling is arbitrary and therefore cannot be defined in any absolute way. In gauge-theoretic terms, just as the photon expresses the fact that we cannot define charge in an absolute sense in the Coulomb gauge, so the graviton would be the gauge particle mediating between EXP and CON “charges”^{3}.

Generalising Newton’s third law, any derivative of action-force applied to a massive body (regardless of mass or composition) will elicit an instantaneous, exactly equivalent and perfectly counter-di- rected reaction-force,. Therefore, the picture suggested is of a massive 3-object (a CON

charge) surrounded by “derivative shells” populated by black holes. The of the 3-object is perfectly balanced by the of the derivative shells, and so the QG definition of freefall would be the superposition of all derivative shells. Therefore mass at the macroscopic level is charge at the microscopic level. In the perspective model, projection of height in the local, macroscopic frame to the remote (effectively) microscopic frame becomes more real, until, at the level of maximum physical reality, it is effectively real. That means that the observer is effectively projected into the microscopic domain, implying a thorough mixing of macroscopic and microscopic scales, and, somewhat outrageously, that electrons are black holes.

Black hole-electron duality (as suggested in [8] - [10] ) opens up many further correspondences. For instance, QED vacuum polarisation, in which the bare electron charge is dressed by slight displacement of virtual pairs away from and towards the charge, respectively, would correspond to GR vacuum polarisation, in

which the bare black hole “EXP” charge is dressed by displacement of virtual charges, dark energy and dark matter, respectively. Also, QED renormalisation, in which the cancellation of divergent inter-

grals may be achieved by removing the electron interior region (where is the classical radius) would suggest that gravitational renormalisation would be likewise achieved by removal of the black hole interior region,.

We might also note that the perspective projection maps the local, macroscopic (black hole) frame to the SM photon epoch following nucleosynthesis but before ions gained electrons. At this time, the densities of relativistic radiation (photons) and non-relativistic matter (atomic nuclei) were equal. The subsequent decoupling of matter and radiation and the formation of charge-neutral atoms corresponds in the perspective model to the global closure of D4. At recombination (the surface of last scattering), the photon mean path length became effectively infinite, and the Universe thus became transparent. At the macroscopic scale, the coincidence (or “why now?”) problem asks why the energy densities of dark energy (i.e., the cosmological constant)

and matter should be comparable. This suggests a perspective map, from the

coincidence problem at the macroscopic scale to the pre-decoupling radiation-matter densities of the SM. In the perspective approach, gravitons at the macroscopic scale are photons at the microscopic scale, in which case, the experimental absence of gravitons would indicate that the Universe is not “yet” gravitationally transparent. We next consider black holes, the firewall question and the information paradox.

6. Black Holes

6.1. Background

If Hawking radiation is thermal [11] , then the scattering matrix is nonunitary. Complementarity allows information to exist in the exterior and interior regions as long as observers cannot compare notes [12] [13] , but the “AMPS” paper [14] showed inconsistencies in the theory’s postulates, reasoning that if evaporation is unitary and maximal entanglement is monogamous, early radiation (C) and late radiation (B) must be entangled, giving rise to a firewall at where entanglement between B and interior modes (A) is broken, or if the EP is to be preserved, then B must be only entangled with A, at the expense of unitarity. The solution [15] is a duality between Einstein-Rosen bridges and EPR entanglement that allows entanglement of A and B (ensuring no drama), and entanglement of B and C via ER bridges (ensuring unitarity). Given certain computational complexity assumptions [16] , Alice, by measuring Hawking radiation, generates a shockwave [17] in the ER bridge, thereby inducing a firewall in the remote black hole throat.

6.2. Perspective Model Interpretation

The effects listed in Section 2 may be demonstrated using Alice and Bob, in orbit around a massive black hole. They synchronise clocks and Alice remains in orbit while Bob begins his radial freefall descent towards the black hole. The effective divergence between their frames (and) is due to the fact that Bob is commoving with global accelerated expansion towards the local, at which ^{4}. Just as at, apparent 3-height decreases with distance, so at in Alice’s frame, Bob’s apparent acceleration decreases as he approaches. The photons comprising his image redshift to, and Alice sees Bob hover (and therefore surmises that he must then burn up as a consequence of the EP). Calculating for the huge Lorentz

and gravitational boosts, Alice records the exact time in her frame that Bob “actually” crosses. In Bob’s frame, the coordinate singularity does not exist. Due to, the 4-mani- fold feels flat, and so the apparent area singularity remains on the horizon at all times. (In Hamil-

ton’s analysis [19] , the illusory horizon recedes in front of Bob until he finally merges with it in finite time at.) The difference between apparent flatness (the tangent space,) and actual global closure is just the observer’s local 5-height (acceleration, or mass), projected to the remote horizon, where it appears as the gauge boson. Classically, one would say that geometry radiates, and assuming minimal 5-height (acceleration) due to, then Hawking radiation (HR) is also minimal (i.e.,). However, in the perspective model, the more fundamental picture is projection of the local to the remote frame; the boson is the “unit of projection”, so, strictly speaking, photons do not travel. Spatial extent is therefore emergent and the “3-ness” of space is just the fact of reduction; “space” is then thought of as the absence of intervening dimensionality.

At some point, Bob begins to experience tidal deformation. Now, according to the Correspondence Principle (CP), classical dynamics (typified by Newton’s) is recovered in the statistical limit and for well-de- fined wavepackets from quantum dynamics (typified by the Schrödinger equation,),

and so the CP must therefore also relate the respective GR and QM “charges”, mass and information, and the associated dynamics (acceleration and measurement) by which each is registered. This validates a comparison between black holes and the slits in the Young double-slit experiment. Assuming no which-path detection, then in the frame of the emitted particle, the slits themselves must become superposed or wavelike. Therefore, if interference fringes are to appear, then just as the particle cannot “know” by which slit it is entering the set-up, so Bob cannot know towards which black hole he is falling. Bob is therefore falling into N black holes and the tidal forces (fluctuations and oscillations) he experiences represent the superposition of distinct black hole spacetime

geometries;. (One would also expect that this gravi-

tational interference or “Weyl field” of gravitational nonuniformity, corresponding to the interference in the double-slit set-up, would be exactly obscured from Alice’s view by the Lorentz and gravitational shifts in her

frame.) However, due to, the 4-surface feels flat (i.e., Bob never experiences his own mass), and the apparent area singularity towards which he is falling therefore never leaves the horizon.

6.3. Scheme for QG and the Information Paradox

As Bob reaches the singularity in his frame in finite time, had his clock been intact, it would have recorded ex-

actly. Thus the “central singularity” and “event horizon” are both horizons and are identified;; i.e., the apparent separation of points A and B becomes more real and is the physical basis

for entanglement. One would then expect that the IR cut-off in Alice’s frame is directly proportional to the UV cut-off as Bob hits the singularity at effective perspectival convergence in his frame (which we think of as). Therefore Hawking radiation corresponds to the collapse vector R, so, and is just “writ large”, thus obviating the need for tunnelling or cosmological protection, since all “central singularities” must be “exposed” in this way.

At, the reduction is from to an apparent area singularity (at the macroscopic level, a black hole microstate, and at the microscopic level, a Dirac electron spinor). At, the

reduction is from to an apparent singularity (at the macroscopic level, a black hole, and at the microscopic level, an electron). Therefore, inter-electron spacing (charge quantisation) is defined in terms of photons, and inter-black hole spacing (gravitational quantisation) is defined in terms of gravitons. To non-gravita- tionally accelerate is to gain extra 5-height and thereby to force the transition and reveal the embedding (a photon). Likewise, to measure is to gain extra 8-height and thereby to force the transition, revealing the embedding (a graviton). (The act of measurement is therefore not one of “amplification” from the microscopic, quantum frame up to the macroscopic, classical frame, but one of projection in the opposite direction.) Thus to measure a black hole is effectively to overlay the transition onto. Therefore, for Alice to measure any property of a black hole is to generate a shockwave [17] in the ER bridge between black hole throats in the maximally extended Schwarzchild solution, or to reveal the identification of the apparent D5 singularity (point A) with the actual D6 singularity (point B) and thereby produce a graviton (manifesting as a firewall) in the opposite throat.

For interference to occur in the double-slit set-up, the separate eigenstates representing the outcomes in which the particle passed through or are quantum linearly superposed; i.e., the wavefunction describes both states, , where is the phase difference between the two paths. In the perspective model, a body’s mass is the projection of its local 5-height to the remote frame, where it appears as the body’s highly contracted (Schwarzchild) radius, , so. Since points A

and B are entangled horizons (i.e., identified), there is a spacetime path-length difference (phase) between frames and (so). By measuring the black hole, Alice is in effect deriving which-path information, destroying Weyl interference (i.e., the loss of the term in Figure 2(b)) and thereby quantising the gravitational field. It was Einstein’s happiest thought [20] - [22] that gravity is eliminated in a freely falling frame, and whilst classically, tidal forces cannot be gauged away, quantum gravitationally they are eliminated. In Alice’s frame, Bob enters the graviton frame at, and, since no time elapses in the graviton frame, is instantly transported to, and in his own frame, due to the temporal phase, he reaches and is instantly transported to (i.e., in the conformally invariant limit, mass and time have no

meaning [7] ). At, an object that disappears over the horizon does not cease to exist but is conserved in 3-space. Likewise, “falling into a black hole” is just a reduction, or projection from the local, macroscopic frame (Bob) to the remote, effectively microscopic frame. Therefore, the information

content of infalling matter defined in terms of inter-electron connectivity (i.e., photons) becomes inter-black hole connectivity (i.e., gravitons). In other words, information is preserved in (or more correctly,), as gravitons exchanged by black holes “in black hole space” (in our D4 frame we might say “inside black holes”, e.g., see [23] - [26] ).

6.4. The Origin of Black Hole Entropy

The limit principle implies a “maximum physical reality” at D6, that D7 is therefore non-physical (i.e., mathematical) and that D8 is in some appropriate sense “beyond” mathematics (i.e., noncomputable). In the perspective model, Alice’s highest freedom (i.e., her measurement independence, which by definition must be noncomputable [27] ) is effectively projected into the remote frame where it appears as quantum indeterminacy. At, local 5-height projected into the remote frame appears at the microscopic level as the coupling constant linking the Dirac spinors of the zigzag electron [5] , and at the macroscopic level as the Schwarzchild radius linking what in the conventional picture are and. At, local 8-

height projected into the remote frame appears at the microscopic level as EPR entanglement (the identification), and at the macroscopic level as an ER bridge. At, an object that disappears over and returns from the opposite 2-space direction demonstrates spherical closure of the 2-surface. Likewise, at, to accelerate is to gain extra 5-height, to see closure of D4 and, by Newton’s third law, to invoke an equal and opposite reaction in which the by-product is heat (the fall-off of energy usefulness). At, to measure is to gain extra 8-height, to see closure of D7 [28] and, by a quantum third law, to invoke an “equal and opposite reaction” (e.g., spin measured along the z-axes of spacelike separated EPR-entangled particles), in which the by- product is entropy (the fall-off of information usefulness). In other words, “physical reality” must demonstrate at least the same degree of freedom in its response to measurement, as proposed in [29] .

In the perspective model, a black hole is just the difference between spacetime path lengths; i.e., the effective separation of points A and B (conventionally, and), which is just. For the freely falling asymptotic Alice, the apparent convergence limit represents a Hawking photon, or unit of projection.

(Since freefall presumes minimum 5-height, the “emission rate” is also minimal;.)The infalling Bob encounters the perspectival convergence limit in his frame as a graviton (a firewall, or surface of maximum acceleration) at so-called. Therefore, is a measure of how many projection-units (Hawking photons) it takes (via) to disperse the black hole’s mass, and

is a measure of how many projection-units (inter-black hole gravitons) it takes to disperse the black hole’s information. However, by projection or by infall (i.e., by reduction), a black hole is both a macroscopic and a microscopic entity, and therefore the path length difference (i.e., the separation of

and) isa maximum of one graviton;. Thus a single graviton or unit of spacetime uncertainty accounts for the entire distance (measured as noncomputability), which is of course proportional to entropy, expressed as and calculated at [11] [30] . This many-to-one reduction is an instance of the fact that quantum measurement reduces multiple complex-weighted, linearly superposed alternatives to a single classical outcome (in accordance with the Born rule,).

Bob (or what remains of his body) always reaches the so-called (and is transported to the so-called, due to)^{5}. Since he experiences no drama, the EP is not violated. Noting the similarity of the EP and a black hole (roughly, that neither reveals composition), it seems reasonable to claim that, since the EP is never violated, Hawking radiation cannot contain quantum information (i.e., is completely thermal).Information “loss” is then seen as an SM phase transition. Just as colour bleaches out of Quarkworld (to be conserved in the form of colour-neutral hadrons), so electric charge () bleaches out of D4 (to be conserved in the form of charge-neutral atoms defined in terms of photon-exchange between electrons), and “mass charge” (CON, EXP) bleaches out of D4 (to be conserved in the form of mass-charge-neutral “cosmic atoms” defined in terms of graviton-exchange between black holes).

7. Discussion and Summary

One would like to explore a number of further implications of the perspective model, including;

1) that the “geometry of time” (i.e., a potential above a spherically closed spacetime surface) is common to GR (classical spacetime at) and QM (quantum spacetime at),

2) that apparent flatness and collapse correspond to the U and R processes of QM,

3) that at, assuming, quantum superposed alternatives are multiple -collapse thresholds (horizons) at one-graviton spacings, and that Schrödinger cat states collapse when associated spacetime curvature reaches a threshold of [26] .

4) that if black holes correspond to paths, impacts on the second screen of the double-slit set-up should replicate the distribution of black holes in that direction,

Figure 6. The four sectors defined by reductions and 3-space scale. Correspondences; (1) Born reciprocity, (2) duality, (3) duality, (4) CP (duality) and (5) duality.

5) that Newton’s third law may be applied to EPR entanglement, in that the outcome of a measurement of spin along the z-axis of one entangled particle is perfectly correlated by the opposite outcome of a measurement of spin along the z-axis of the spacelike separated particle,

6) that, as at, apparent 3-height is maximum in the local frame and projected to an apparent minimum in the remote frame, so at, the local “rate at which time passes” (i.e., maximised proper time,) is projected to the remote frame and juxtaposed with “cosmic” time,

7) that the projection of local (macroscopic) values into the remote (effectively microscopic) frame explains apparent fine-tuning, naturalness, hierarchy and large number problems.

To summarise, the two principle reductions (and) and the two scale extremes (i.e., macroscopic and microscopic) define four sectors (Figure 6).

^{5}The graviton as “unit of spacetime uncertainty” accounts for what would otherwise be a causality-violating, backwards-in-time jump.
