    3. 3. The objectives are: • To investigate the conditions under which the mathematical formalisms of general relativity and of quantum mechanics go over each other • To interpret those conditions meaningfully and physically • To comment that interpretation mathematically and philosophically 3
    4. 4. Scientific prudence, or what are not our objectives: • To say whether entanglement and gravity are the same or they are not: For example, our argument may be glossed as a proof that any of the two mathematical formalisms needs perfection because gravity and entanglement really are not the same • To investigate whether other approaches for quantum gravity are consistent with that if any at all
    5. 5. Background • Eric Verlinde’s entropic theory of gravity (2009): “Gravity is explained as an entropic force caused by changes in the information associated with the positions of material bodies” • The accelerating number of publications on the links between gravity and entanglement, e.g. Jae-Weon Lee, Hyeong-Chan Kim, Jungjai Lee’s “Gravity as Quantum Entanglement Force” : “We conjecture that quantum entanglement of matter and vacuum in the universe tend to increase with time, like entropy …
    6. 6. Background Jae-Weon Lee, Hyeong-Chan Kim, Jungjai Lee’s “Gravity as Quantum Entanglement Force” : …, and there is an effective force called quantum entanglement force associated with this tendency. It is also suggested that gravity and dark energy are types of the quantum entanglement force …” Or: Mark Van Raamsdonk’s “Comments on quantum gravity and entanglement”
    7. 7. Background: For the gauge/gravity duality “The gauge/gravity duality is an equality between two theories: On one side we have a quantum field theory in d spacetime dimensions. On the other side we have a gravity theory on a d+1 dimensional spacetime that has an asymptotic boundary which is d dimensional” • Dr. Juan Maldacena is the recipient of the prestigious Fundamental Physics Prize ($3M) 4
    8. 8. Background: Poincaré conjecture The third (of 7 and only solved) Millennium Prize Problem proved by Gregory Perelman ($1M refused): Every simply connected, closed 3-manifold is homeomorphic to the 3-sphere The corollary important for us is: 3D space is homeomorhic to a cyclic 3+1 topological structure like the 3-sphere: e.g. the cyclically connected Minkowski space 5
    9. 9. The gauge/gravity duality & Poincaré conjecture 3D (gauge) /3D+1 (gravity) are dual in a sense 3D & a 3D+1 cyclic structure are homeomorphic “What about that duality if 3D+1 (gravity) is cyclic in a sense?” – will be one of our questions
    10. 10. Background: The Higgs boson  It completes the standard model without gravity, even without leaving any room for it: The Higgs boson means: No quantum gravity!  As the French academy declared "No perpetuum mobile" and it was a new principle of nature that generated thermodynamics: 6
    11. 11. Background: The Higgs boson "No quantum gravity!" and it is a new very strange and amazing principle of nature If the best minds tried a century to invent quantum gravity and they did not manage to do it, then it merely means that quantum gravity does not exist in principle So that no sense in persisting to invent the "perpetuum mobile" of quantum gravity, however there is a great sense to build a new theory on that new principle:
    12. 12. Background: The Higgs boson 1. The theory of gravity which is sure is general relativity, and it is not quantum: This is not a random fact 2. If the standard model is completed by the Higgs boson but without gravity, then the cause for that is: The standard model is quantum. It cannot include gravity in principle just being a quantum theory 3. Of course, a non-universality of quantum theory is a big surprise and quite incomprehensible at present, but all scientific experience of mankind is full of surprises
    13. 13. General relativity vs. the standard model Interaction, Force, Energy (mass) Their mechanical action Gravitational mass Gravitational ones Inertial mass The weak, electromagnetic, strong ones The standard model, which is quantum General relativity, which is smooth Inertial mass is the measure of resistance vs. the action of any force field. Gravitational mass is the measure of gravity action And what about entanglement and inertial mass? 7
    14. 14. Our strategy on that background is... 1. ... to show that entanglement is another and equivalent interpretation of the mathematical formalism of any force field (the right side of the previous slide) 2. ... to identify entanglement as inertial mass (the left side) 3. ... to identify entanglement just as gravitational mass by the equality of gravitational and inertial mass 4. ... to sense gravity as another and equivalent interpretation of any quantum-mechanical movement and in last analysis, of any mechanical (i.e. space-time) movement at all
    15. 15. If we sense gravity as another and equivalent interpretation of any movement, then ... The standard model repre- sents any quantum force field: strong, electromag- netic, or weak field It does not and cannot re- present gravity because it is not a quantum field at all: It is the smooth image of all quantum fields Space-timeEnergy-momentum Complex Banach (Hilbert) Space Complex probability distribution = Two probability distributions trajectoryquantum force field entangle- ment Pseudo- Riemanian basis 8
    16. 16. The Higgs boson is an answer ... and many questions: What about the Higgs field? The standard model unifies electromagnetic, weak and strong field. Is there room for the Higgs field? What about the Higgs field and gravity? What about the Higgs field and entanglement? ... and too many others ... We will consider the Higgs field as a “translation” of gravity & entanglement in the language of the standard model as a theory of unified quantum field
    17. 17. However what does “quantum field” mean? Is not this a very strange and controversial term? Quantum field means that field whose value in any space-time point is a wave function. If the corresponding operator between any two field points is self-adjoint, then:  A quantum physical quantity corresponds to it, and  All wave function and self-adjoint operators share a common Hilbert space or in other words, they are not entangled
    18. 18. Quantum field is the only possible field in quantum mechanics, because: • It is the only kind of field which can satisfy Heisenberg’s uncertainty • The gradient between any two field points is the gradient of a certain physical quantity • However the notion of quantum field does not include or even maybe excludes that of entanglement: If our suspicion about the close connection between entanglement and gravity is justified, then this would explain the difficulties about “quantum gravity”
    19. 19. Then we can outline the path to gravity from the viewpoint of quantum mechanics: ... as an appropriate generalization of ‘quantum field’ so that to include ‘entanglement’:  If all wave functions and operators (which will not already be selfadjoint in general) of the quantum filed share rather a common Banach than Hilbert space, this is enough. That quantum field is a generalized one. However there would be some troubles with its physical interpretation
    20. 20. Which are the troubles? The “cure” for them is to be generalized correspondingly the notion of quantity in quantum mechanics. If the operator is in Banach space (correspondingly, yet no selfadjoint operator), then its functional is a complex number in general Its modulus is the value of the physical quantity The expectation of two quantities is nonadditive in general
    21. 21. More about the “cure” The quantity of subadditivity (which can be zero, too) is the degree (or quantity) of entanglement 𝑒: 𝑒 = 𝐴1 + 𝐴2 𝑖𝑛: 𝐴1 + 𝐴2 − 𝐴1 + 𝐴2 , where 𝐴1, 𝐴2 are as quantities in the two entangled quantum systems 1 and 2. To recall that any quantity 𝐴 in quantum mechanics is defined as mathematical expectation, i.e. as a sum or integral of the product of any possible value and its probability, or as a functional: 𝐴 = −∞ ∞ 𝑎𝑝 𝑎 𝑑𝑎 = −∞ ∞ 𝚿 𝐴 (𝚿 ∗) 9
    22. 22. More and more about the “cure” (!!!) 𝑒 cannot be quantized in principle even if 𝐴1, 𝐴2 are quantum or quantized, because as expectation as probability are neither quantum, nor quantizable since wave function is smooth (a “leap” in probability would mean infinite energy) (!!!) Granted entanglement and gravity are the same or closely connected, this explains:  (1) why gravity cannot be quantized;  (2) why gravity is always nonnegative (there is no antigravity)
    23. 23. More and more about the “cure” Then what is gravity? It cannot be define in terms of “classical” quantum field, but only in those of generalized quantum field It is always the smooth curvature or distortion of “classical” quantum field It is an interaction (force, field) of second order: rather the change of quantum field in space-time than a new quantum field That change of quantum field is neither quantum, nor quantizable: It cannot be a new quantum field in principle Its representation as a whole (or from the “viewpoint of eternity”) is entanglement
    24. 24. Then, in a few words, what would gravity be in terms of generalized quantum field? ... a smooth space-time DoF constraint imposed on any quantum entity by any or all others Entanglement is another (possibly equivalent) mapping of gravity from the probabilistic rather than space-time viewpoint of “eternity” The smooth space-time DoF constraint in each moment represents a deformed “inwards”3D light sphere of the 4-Minkowski-space light cone (“outwards” would mean antigravity) The well-ordered (in time) set of all such spheres in all moments constitutes the pseudo-Riemannian space of general relativity
    25. 25. The language of quantum field theory: the conception of “second quantization” What does the “second quantization” mean in terms of the “first quantization”? If the “first quantization” gives us the wave function of all the quantum system as a whole, then the “second quantization” divides it into the quantum subsystems of “particles” with wave functions orthogonal between each other; or in other words, these wave functions are not entangled. Consequently, the “second quantization” excludes as entanglement as gravity in principle
    26. 26. The second quantization in terms of Hilbert space The second quantization divides infinitedimensional Hilbert space into also infinitedimensional subspaces A subspace can be created or annihilated: This means that a particle is created or annihilated The second quantization juxtaposes a certain set of Hilbert subspaces with any space-time point One or more particles can be created or annihilated from any point to any point However though the Hilbert space is divided into subspaces from a space-time point to another in different ways, all subspaces share it
    27. 27. A philosophical interpretation both of quantum (I) and of quantized (II) field Quantum vs. quantized field means for any space- time point to juxtapose the Hilbert space and a division into subspaces of its The gauge theories interpret that as if the Hilbert space with its division into subspaces is inserted within the corresponding space-time point Any quantum conservation law is a symmetry or a representation into Hilbert space of the corresponding group The standard model describes the general and complete group including all the “strong”, “electromagnetic” and “weak” symmetries
    28. 28. A philosophical interpretation as to the closedness of the standard model The standard model describes the general and complete group including all the “strong”, “electromagnetic” and “weak” symmetries within any space-time point Consequently the standard model is inside of any space-time point, and describes movement as a change of the inside structure between any two or more space-time points However gravity is outside and remains outside of the standard model: It is a relation between two or more space-time points but outside and outside of them as wholenesses
    29. 29. Need to add an interpretation of quantum duality à la Nicolas of Cusa: After Niels Bohr quantum duality has been illustrated by the Chinese Yin and Yang However now we need to juxtapose them in scale in Nicolas of Cusa's manner: Yin becomes Yang as the smallest becoming the biggest, and vice versa: Yang becomes Yin as the biggest becoming the smallest Besides moreover, Yin and Yang continue to be as parallel as successive in the same scale
    30. 30. And now, from the philosophical to the mathematical and physical ...: Minkowski space A space-time trajectory Hilbert space A wave function A Yin-Yang mathematical structure 1 0
    31. 31. However ...: Have already added à la Nicolas of Cusa’s interpretation to that Yin-Yang structure, so that ... The “biggest” of the space-time whole is inserted within the “smallest” of any space-time point The “biggest” of the Hilbert-space whole is inserted within the “smallest” of any Hilbert-space point 1 1
    32. 32. In last analysis we got a cyclic and frac-tal Yin-Yang mathematical structure ... Will check whether it satisfies our requirements: Yin and Yang are parallel to each other Yin and Yang are successive to each other Yin and Yang as the biggest are within themselves as the smallest Besides, please note: it being cyclic need not be infinite! Need only two entities, “Yin and Yang”, and a special structure tried to be described above 1 2
    33. 33. Will interpret that Yin-Yang structure in terms of the standard model & gravity Our question is how the gravity being “outside” space-time points as a curving of a smooth trajectory, to which they belong, will express itself inside, i.e. within space-time points representing Hilbert space divided into subspaces in different ways Will try to show that: The expression of gravity “outside” looks like entanglement “inside” and vice versa Besides, the expression of entanglement “outside” looks like gravity inside of all the space- time and vice versa
    34. 34. Back to the philosophical interpretation of quantum (I) or quantized (II) field The principle is: The global change of a space- time trajectory (or an operator in pseudo- Riemannian space) is equivalent to, or merely another representation of a mapping between two local Hilbert spaces of Banach space (entanglement) The same principle from the viewpoint of quantum mechanics and information looks like as follows: Entanglement in the “smallest” returns and comes from the “outsides” of the universe, i.e. from the “biggest”, as gravity
    35. 35. Back to the philosophical interpretation, or more and more „miracles“ Turns out the yet “innocent” quantum duality generates more and more already “vicious” dualities more and more extraordinary from each to other, namely: ... of the continuous (smooth) & discrete ... of whole & part  ... of the single one & many ... of eternity & time ... of the biggest & smallest ... of the external & internal ... and even ... of “&” and duality
    36. 36. ... where “&” means ... ... equivalence ... relativity ... invariance ... conservation
    37. 37. The second quantization in terms of Banach space If the Banach space is smooth, it is locally “flat”, which means that any its point separately implies a “flat” and “tangential” Hilbert space at this point However the system of two or more points in Banach space do not share in general a common tangential Hilbert space, which is another formulation of entanglement One can always determines a self-adjoint operator (i.e. a physical quantity) between any two points in Banach space (i.e. between the two corresponding tangential Hilbert spaces mapping by the operator)
    38. 38. The second quantization in terms of Banach space If we can always determine a self-adjoint operator (i.e. a physical quantity) between any two points in Banach space, then follows the second quantization is invariant (or the same) from Hilbert to any smooth Banach space, and vice versa, consequently between any two smooth Banach spaces As entanglement as gravity is only external, or both are “orthogonal” to the second quantization: It means that no any interaction or unity between both gravity and entanglement, on the one hand ...
    39. 39. The second quantization in terms of Banach space As entanglement as gravity is only external, or both are “orthogonal” to the second quantization: It means that no any interaction or unity between both gravity and entanglement, on the one hand, and the three rest, on the other, since the latters are within Hilbert space while the formers are between two (tangential) Hilbert spaces However as entanglement as gravity can be divided into the second-quantized parts (subspaces) of the Hilbert space, which “internally” is granted for the same though they are at some generalized “angle” “externally”
    40. 40. The problem of Lorentz invariance Try to unite the following facts: Relativity Quantum theory The Lorentz noninvariant are: Newton’s mechanics Schrödinger’s quantum mechanics The Lorentz invariant are: Maxwell’s theory of electromagnetic field Einstein’s special relativity Dirac’s quantum mechanics of electromagnetic field The locally Lorentz invariant (but noninvariant globally) are: Einstein’s general relativity Our hypothesis of entanglement & gravity 1 3
    41. 41. ... whether gravity is not a “defect” of electromagnetic field... However mass unlike electric (or Dirac’s magnetic) charge is a universal physical quantity which characterizes anything existing A perfect, “Yin-Yang” symmetry would require as the locally “flat” to become globally “curved” as the locally “curved” to become globally “flat” as the “biggest” to return back as the smallest and locally “flat” For example this might mean that the universe would have a charge (perhaps Dirac’s “monopole” of magnetic charge), but not any mass: the curved Banach space can be seen as a space of entangled spinors
    42. 42. Electromagnetic field as a “Janus” with a global and a local “face” Such a kind of consideration like that in the previous slide cannot be generalized to the “weak” and “strong” field: They are always local since their quanta have a nonzero mass at rest unlike the quantum of electromagnetic field: the photon As to the electromagnetic field, both global and local (the latter is within the standard model) consideration is possible
    43. 43. Electromagnetic field as a “Janus” with a global and a local “face” Conclusion: gravity (& entanglement) is only global (external), weak & strong interaction is only local (internal), and electromagnetic field is both local and global: It serves to mediate both between the global and the local and between the external and the internal Consequently, it conserves the unity of the universe
    44. 44. More about the photon two faces: • It being global has no mass at rest • It being local has a finite speed in spacetime In comparison with it: o Entanglement & gravity being only global has no quantum, thus neither mass at rest nor a finite speed in spacetime o Weak & strong interaction being only local has quanta both with a nonzero mass at rest and with a finite speed in spacetime
    45. 45. Lorentz invariance has a local and a global face, too: In turn, this generates the two faces of photon The local “face” of Lorentz invariance is both within and at any spacetime point. It “within” such a point is as the “flat” Hilbert space, and “at” it is as the tangential, also “flat” Minkowski space Its global “face” is both “within” and “at” the totality of the universe. It is “within” the totality flattening Banach space by the axiom of choice. It is “at” the totality transforming it into a spacetime point
    46. 46. It is about time to gaze that Janus in details in Dirac’s brilliant solving by spinors In terms of philosophy, “spinor” is the total half (or “squire root”) of the totality. In terms of physics, it generalizes the decomposition of electromagnetic field into its electric and magnetic component. The electromagnetic wave looks like the following: 1 4
    47. 47. That is a quantum kind of generalization. Why on Earth? First, the decomposition into a magnetic and an electric component is not a decomposition of two spinors because the electromagnetic field is the vector rather than tensor product of them Both components are exactly defined in any point time just as position and momentum as to a classical mechanical movement. The quantity of action is just the same way the vector than tensor product of them Consequently, there is another way (the Dirac one) quantization to be described: as a transition or generalization from vector to tensor product
    48. 48. Well, what about such a way gravity to be quantized? The answer is really quite too surprising: General relativity has already quantized gravity this way! That is general relativity has already been a quantum theory and that is the reason not to be able to be quantized once again just as the quant itself cannot be quantized once again! What only need is to gaze at it and contemplate it to see how it has already sneaked to become a quantum theory unwittingly
    49. 49. Cannot be, or general relativity as a quantum theory Of course the Dirac way of keeping Lorentz invariance onto the quantum theory is the most obvious for general relativity: It arises to keep and generalize just the Lorentz invariance for any reference frame However the notion of reference frame conserves the smoothness of any admissable movement requiring a definite speed toward any other reference frame or movement Should see how the Dirac approach generalizes implicitly and unwittingly “reference frame” for discrete (quantum) movements. How?
    50. 50. “Reference frame” after the Dirac approach • “Reference frame” is usually understood as two coordinate frames moving to each other with a relative speed 𝑣(𝑡) • However we should already think of it after Dirac as the tensor product of the given coordinate frames. This means to replace 𝑣(𝑡) with 𝛿(𝑡) (Dirac delta function) in any 𝑡 = 𝑡0 . • Given a sphere 𝑺 with radius 𝒙 𝟐 + 𝒚 𝟐 + 𝒛 𝟐 + 𝒗 𝟐 𝒕 𝟐, it can represent any corresponding reference frame in Minkowski space. 𝑺 can be decomposed into any two great circles 𝑺 𝟏⨂𝑺 𝟐 of its, perpendicular to each other, as the tensor product ⨂ of them 1 5
    51. 51. “Reference frame” after the Dirac approach Given a sphere 𝑺 with radius 𝒙 𝟐 + 𝒚 𝟐 + 𝒛 𝟐 + 𝒗 𝟐 𝒕 𝟐 decomposed into any two great circles 𝑺 𝟏⨂𝑺 𝟐 of its, 𝑺, 𝑺 𝟏, 𝑺 𝟐 are with the same radius. We can think of 𝑺 𝟏, 𝑺 𝟐 as the two spinors of a reference frame after Dirac If we are thinking of Minkowski space as an expanding sphere, then its spinor decomposition would represent two planar, expanding circles perpendicular to each other, e.g. the magnetic and electric component of electromagnetic wave as if being quantumly independent of each other 1 6
    52. 52. The praising and celebration of sphere The well-known and most ordinary sphere is the crosspoint of: ... quantization ... Lorentz invariance ... Minkowski space ... Hilbert space ... qubit ... spinor decomposition ... electromagnetic wave ... wave function ... making their uniting, common consideration, and mutual conceptual translation – possible!
    53. 53. More about the virtues of the sphere It is the “atom” of Fourier transform: The essence of Fourier transform is the (mutual) replacement between the argument of a function and its reciprocal: 𝑓 𝑡 ↔ 𝑓 1 𝑡 = 𝑓(𝜔), or quantumly: 𝑓(𝑡) ↔ 𝑓(𝐸), As such an atom, it is both: - as any harmonic in Hilbert space: 𝑓𝑛 𝜔 = 𝑒 𝑖𝑛𝜔 - as any inertial reference frame in Minkowski space: 𝑓 𝑡 = 𝑟(𝑡) = 𝑐2 𝑡2 − 𝑥2 − 𝑦2 − 𝑧2 1 7
    54. 54. Again about the spinor decomposition Since the sphere is what is “spinorly” decomposed into two orthogonal great circles, the spinor decomposition is invariant to Fourier transform or to the mutual transition of Hilbert and Minkowski space In particular this implies the spinor decompsition of wave function and even of its “probabilistic interpretation”: Each of its two real “spinor” components can be interpreted as the probability both of a discrete quantum leap to, and of a smooth reaching the corresponding value
    55. 55. A necessary elucidation of the connection between probabilistic (mathematical) and mechanical (physical) approach Totality aka eternity aka infinity No axiom of choice (the Paradise) Both need choice (axiom) Probabilistic (mathematical) approach Mechanical (physical) approach Minkowski space: from the “Earth” to the “Paradise“ by the “stairs” of time Hilbert space: from the “Paradise” to the “Earth “ by the “stairs” of energy 1 8
    56. 56. Coherent state, statistical ensemble, and two kinds of quantum statistics • The process of measuring transforms the coherent state into a classical statistical ensemble • Consequently, it requires the axiom of choice • However yet the mathematical formalism of Hilbert space allows two materially different interpretations corresponding to the two basic kinds of quantum statistics, of quantum indistinguishability, and of quantum particles: bosons and fermions
    57. 57. The axiom of choice as the boundary between bosons and fermions The two interpretations of a coherent state mentioned above are: As a nonordered ensemble of complex (= two real ones) probability distribution after missing the axiom of choice – aka bosons As a well-ordered series either in time or in frequency (energy) equivalent to the axiom of choice – aka fermions
    58. 58. The sense of quantum movement represented in Hilbert space From classical to quantum movement: the way of generalization: A common (namely Euclidean) space includes the two aspects of any classical movement, which are static and dynamic one and corresponding physical quantities to each of them Analogically, a common (namely Hilbert) space includes the two aspects of any quantum movement: static (fermion) and dynamic (boson) one, and their physical quantities
    59. 59. Quantum vs. classical movement However the two (as static as dynamic) aspects of classical movement are included within the just static (fermion) aspect of quantum movement as the two possible “hypostases” of the same quantum state The static (fermion) aspect of quantum movement points at a quantum leap (the one fermion of the pair) or at the equivalent smooth trajectory between the same states (the other) These two fermions for the same quantum state can be seen as two spinors keeping Lorentz invariance
    60. 60. The spin statistics theorem about fermions If one swaps the places of any two quantum particles, this means to swap the places between “particle” and “field”, or in other words to reverse the direction “from time to energy” into “from energy to time”, or to reverse the sign of wave function The following set-theory explanation may be useful: If there are many things, which are the same or “quantumly indistinguishable”, there are anyway two opportunities: either to be “well-ordered” as the positive integers are (fermions), or not to be ordered at all as the elements of a set (bosons). Though indistinguishable, the swap of their corresponding ordinal (serial) number is distinguishable in the former case unlike the latter one
    61. 61. However that “positive-integers analogy” is limited The well-ordering of positive integers has “memory” in a sense: One can distinguish two swaps, too, rather than only being one or more swaps available (as the fermions swap) The well-ordering of fermions has no such memory. The axiom of choice and well-ordering theorem do not require such a memory However if all the choices (or the choices after the well-ordering of a given set) constitute a set, then such a memory is posited just by the axiom of choice
    62. 62. Positive integers vs. fermions vs. bosons illustrated Fermions Positive integers Bosons Initial state Swap After a time Naming True indistinguish- ability Quantum indistinguishability “Weak” (in)distinguish- ability ... ........ ... ........ ... ........ 1, 2, 3, 4, 5, ... 1, 5, 3, 4, 2, ... 1, 2, 3, 4, 5, ... 1, 2, 3, 4, 5, ... 1, 5, 3, 4, 2, ... 1, 5, 3, 4, 2, ... True distinguish- ability 1 9
    63. 63. Quantum vs. classical movement in terms of (quantum in)distinguishability Quantum movement Classical movement Dynamic to static aspect: one to one Dynamic to static aspect: much to many Dynamic (boson) aspect: true in- distinguishability Static (fermion) aspect: weak in- distinguishability Quantum indistinguishability 𝑴𝒖𝒄𝒉 ⟺ 𝑴𝒂𝒏𝒚 Distinguishability 𝒕 Dynamic (momentum) aspect Static (position) aspect Wave function as the characteristic function of a random complex quantity Wave function as a (well- ordered) vector Hilbert space Pseudo- Riemannian space 2 0
    64. 64. Our interpretation of fermion antisymmetry vs. boson symmetry The usual interpretation suggests that both the fermion and boson ensembles are well- ordered: However any fermion swap reverses the sign of their common wave function unlike any boson swap Our interpretation is quite different: Any ensemble of bosons is not and cannot be well-ordered in principle unlike a fermion one: The former is “much” rather than “many”, which is correct only as to the latter
    65. 65. The well-ordering of the unorderable: fermions vs. bosons The unorderable boson ensemble represents the real essence of quantum field unlike the “second quantization”. The latter replaces the former almost equivalently with a well-ordered, as if a “fermion” image of it In turn this hides the essence of quantum movement, which is “much – many”, substituting it with a semi-classical “many – many”
    66. 66. What will “spin” be in our interpretation? In particular, a new, specifically quantum quantity, namely “spin”, is added to distinguish between the well-ordered (fermion) and the unorderable (boson) state in a well-ordered way However this makes any quantum understanding of gravity (or so-called “quantum gravity”) impossible, because “quantum” gravity requires the spin to be an arbitrary real number In other words, gravity is the process in time (i.e. the time image of that process), which well- orders the unorderable The true “much – many” transition permits as a “many” (gravity in time, or “fermion”) interpretation as a “much” (entanglement out of time, or “boson”) interpretation
    67. 67. Our interpretation of fermion vs. boson wave function In turn it requires distinguishing between: the standard, “fermion” interpretation of wave function as a vector in Hilbert space (a square integrable function), and a new,“boson”interpretation of it as the characteristic function of a random complex quantity The former represents the static aspect of quantum movement, the latter the dynamic one. The static aspect of quantum movement comprises both the static (position) and dynamic (momentum) aspect of classical movement, because both are well-ordered, and they constitute a common well-ordering
    68. 68. Entangled observables in terms of “spin” distinction The standard definition of quantum quantity as “observable” allows its understanding:  as a “fermion – fermion” transform, as a “boson – boson” one as well as “fermion – boson” and “boson – fermion” one Only entanglement and gravity can create distinctions between the former two and the latter two cases. Those distinctions are recognizable only in Banach space, but vanishing in Hilbert space
    69. 69. The two parallel phases of quantum movement Quantum field (the bosons) can be thought of as the one phase of quantum movement parallel to the other of fermion well-ordering: The phase of quantum field requires the universe to be consider as a whole or indivisible “much” or even as a single quant The parallel phase of well-ordering (usually represented as some space, e.g. space-time) requires the universe to yield the well-known appearance of immense and unbounded space, cosmos, i.e. of an indefinitely divisible “many” or merely as many quanta
    70. 70. Why be “quantum gravity” a problem of philosophy rather than of physics? The Chinese "Taiji 太極 (literally "great pole"), the "Supreme Ultimate" can comprise both phases of quantum movement. Then entanglement & gravity can be seen as “Wuji 無極 "Without Ultimate" In other words, gravity can be seen as quantum gravity only from the "Great Pole" This shows why "quantum gravity" is rather a problem of philosophy, than and only then of physics 2 1
    71. 71. Hilbert vs. pseudo-Riemannian space: a preliminary comparison As classical as quantum movement need a common space uniting the dynamic and static aspect: Hilbert space does it for quantum movement, and pseudo-Riemannian for classical movement Quantum gravity should describe uniformly as quantum as classical movement. This requires a forthcoming comparison of Hilbert and pseudo- Riemannian space as well as one, already started, of quantum and classical movement
    72. 72. Hilbert vs. pseudo-Riemannian space as actual vs. potential infinity Two oppositions are enough to represent that comparison from the viewpoint of philosophy: Hilbert space is ‘flat’, and pseudo-Riemannian space is “curved” Any point in Hilbert space represents a complete process, i.e. an actual infinity, and any trajectory in pseudo-Riemannian space a process in time, i.e. in development, or in other words, a potential infinity
    73. 73. Hilbert vs. pseudo-Riemannian space: completing the puzzle Oppo- sition Process in time Actual infinity Curve Pseudo- Riemannian space Gravity, General relativity Banach space Entanglement Quantum information Flat Minkowski space Electromag- netism Special relativity Hilbert space Electromagnetic, weak and strong interaction Quantum mechanics The standard model 2 2
    74. 74. Our thesis in terms of that table Curve Pseudo- Riemannian space Gravity, General relativity Banach space Entanglement Quantum information Entanglement is gravity as a complete process Gravity is entanglement as a process in time 2 3
    75. 75. A fundamental prejudice needs elucidation not to bar: The complete wholeness of any process is „more“ than the same process in time, in development Actual infinity is “more” than potential infinity The power of continuum is “more” than the power of integers The objects of gravity are bigger than the objects of quantum mechanics The bodies of our everyday world are much “bigger” than the “particles” of the quantum world, and much smaller than the universe
    76. 76. Why is that prejudice an obstacle? According to the first three statements entanglement should be intuitively “more” than gravity However according to the second two statements gravity should be intuitively much “smaller” than entanglement Consequently a contradiction arises according to our intuition: Gravity should be as “less” in the first relation as much “bigger” in the second relation An obvious, but inappropriate way out of it is to emphasis the difference between the relations
    77. 77. Why is such a way out inappropriate? The first relation links the mathematical models of entanglement and gravity, and the second one does the phenomena of gravity and entanglement To be adequate both relations to each other, one must double both by an image of the other relation into the domain of the first one. However one can show that the “no hidden parameters” theorems forbid that For that our way out of the contradiction must not be such a one
    78. 78. Cycling is about to be our way out of the contradiction Should merely glue down both ends to each other: the biggest as the most to the least as the smallest. However there is a trick: There not be anymore the two sides conformably of the “big or small” as well as of the “more or less” but only a single one like this: 2 4
    79. 79. Once again the pathway is ...: from the two sides of a noncyclic strip to the two cyclic sides of a cylinder to a single and cyclic side of a Möbius strip to an inseparable whole of a merely “much” to the last one as the “second”side of the Möbius band cyclically passing into the other 2 5
    80. 80. Holism of the East vs. linear time of the West The edge of gluing the Möbius strip is a very special kind: It is everywhere and nowhere. We can think of it in terms of the East, together:  as Taiji 太極 (literally "great pole"), or "Supreme Ultimate“  as Wuji 無極 (literally "without ridgepole") or "ultimateless; boundless; infinite“ As a rule, the West thought torments and bars quantum mechanics: It feels good in the Chinese Yin-Yang holism. (In the West, to be everywhere and nowhere is God's property) 2 6
    81. 81. The “Great Pole” of cycling in terms of the axiom of choice or movement The “Great Pole” as if “simultaneously” both (1) crawls in a roundabout way along the cycle as Taiji, and (2) comprises all the points or possible trajectories in a single and inseparable whole as Wuji By the way, quantum mechanics itself is like a Great Pole between the West and the East: It must describe the holism of the East in the linear terms of the West, or in other words whole as time
    82. 82. Being people of the West, we should realize the linearity of all western science!  Physics incl. quantum mechanics is linear as all the science, too  For example we think of movement as a universal feature of all, because of which there is need whole to be described as movement or as time. In terms of the Chinese thought, it would sound as Wiji in “terms” of Taiji, or Yin in “terms” of Yang  Fortunately, the very well developed mathematics of the West includes enough bridges to think of whole linearly: The most essential and important link among them is the axiom of choice
    83. 83. The axiom of choice self-referentially The choice of all the choices is to choose the choice itself, i.e. the axiom of choice itself , or in philosophi- cal terms to choose between the West and the East However it is a choice already made for all of us and instead of all of us, we being here (in the West) and now (in the age of the West). Consequently we doom to think whole as movement and time, i.e. linearly The mathematical notions and conceptions can aid us in uniting whole and linearity (interpreted in physics and philosophy as movement and time), though In particular, just this feature of mathematics determines its leading role in contemporary physics, especially quantum mechanics
    84. 84. Boson – fermion distinction in terms both of whole and movement The two version of any fermion with different spin can be explain in terms of the whole as the same being correspondingly insides and outsides the whole since the outsides of the whole has to be inside it in a sense As an illustration, a fermion rotated through a full 360° turns out to be its twin with reversed spin: In other words, it turns “outsides” after a 2𝜋 rotation in a smooth trajectory passing along the half of the universe. Look at it on a Möbuis strip:

Exactly the half + 𝟏 𝟐 fermion − 𝟏 𝟐 fermion The universe of the universe is inserted between its two electrons which differ from each other only with reversed spin: The West thinks of the universe as the extremely immense, and of the electrons and atoms as the extre- mely tiny. However as quantum mechanics as Chinese thought shows that they pass into each other everywhere and always 2 8
    87. 87. + 𝟏 𝟐 fermion − 𝟏 𝟐 fermion The West's single pathway along or through Taiji is mathematics, though Taiji 太極 is the Chinese transition between the tiniest and the most immense A fortunate exception is Nicolas of Kues 2 9
    88. 88. How on Earth is it possible? Mathematics offers the universe to be considered in two equivalent Yin – Yang aspects corresponding relatively to quantum field (bosons) and quantum “things” (fermions): an unorderable at all set for the former, and a well-orderable space for the latter It is just the axiom of choice (more exactly, Scolem’s “paradox”) that makes them equivalent or relative. Hilbert space can unite both aspects as two different (and of course, equivalent by means of it) interpretations of it: (1) as the characteristic function of a complex (or two real) quantity(es) (quantum field, bosons), and (2) as a vector (or a square integrable function)

    93. 93. The mapping between numbers and a sundry A few simplifying assumptions: 1. The sundry constitutes a set, 𝑆1 as well as the numbers, 𝑆2 2. Two smooth functions can substitute for the state of that mapping in any moment 3. Those two functions 𝑓1, 𝑓2 are correspondingly:  a probability distribution: 𝑆1 𝑓1 𝑆2  a “field”: 𝑆2 𝑓2 𝑆1 3 3
    94. 94. Quantum mechanics solves the general problem under those assumptions The general problem is the quantitative description of the universe: too complicated!

    95. 95. The solving of quantum mechanics in terms of gauge theories  The leading notion is “fiber bundle”: The Möbius strip is an as good as simple enough example of fiber bundle: Its as topologic as metric properties are quite different locally vs. globally Möbius strip Metrically Topologically Locally flat two-side Globally curved one-side 3 5
    96. 96. Möbius strip as a fiber bundle “radius” for fiber, F “circle” for bundle the same “radius” from the “other side” for base 3 6
    97. 97. The definition of “fiber bundle” by the example of a Möbuis strip The fiber bundle is determined and defined precisely by the topological transform from it to base space or vice versa: i.e. correspondingly as unfolding from a flat sheet (base space) to the Möbius strip (fiber strip), or folding vice versa, in our example: By its unfolding Or By its folding 3 7
    98. 98. More precise definition of fiber bundle yet using the "Möbius" illustration Let us 𝑨 and 𝑩 are two “radiuses” of the two sides of a Möbius strip, and 𝑨 𝒔, 𝑩 𝒔 are the same “radiuses” on the sheet. Then the fiber bundle is described as the triangle of mappings for any 𝑨, 𝑩, 𝑨 𝒔, 𝑩 𝒔 as follows: 𝑨 𝑩 𝑨⨂𝑩 „𝑨⨂𝑩“ means Cartesian product 3 8
    99. 99. The definition without any illustration Arbitrary neighborhoods of arbitrary topological spaces for the “radiuses” of the illustration However the topological spaces are usual Hilbert spaces or subspaces in the physical interpretation of fiber bundle in the gauge theories In other words, Hilbert spaces substitute for the “radiuses” of Möbius strip, in gauge theories 3 9
    100. 100. The leading idea of gauge theory Let us fancy the two “radiuses” or Hilbert spaces 𝐴 and 𝐵 correspondingly as the reference and gauge mark of an uncalibrated indicator, and 𝐴 𝑠 and 𝐵𝑠 are the same after the precise calibrating: 𝑨 𝒔 ≡ 𝑩 𝒔 𝑨 𝑩 0 0 an uncalibrated indicator the indicator calibrated Fiber bundle Cartesian product The Standard Model 4 0
    101. 101. The universality of calibration The calibration should be identical for any indication, and this is true as to weak, electromagnetic, and strong interaction, but not as to gravity For that the Standard Model comprises the former three but not the latter A necessary condition is quantization, which guarantees the two vectors A and B to exist Our conjecture will be: It is quantization that gravity cannot satisfy and in principle, there can be no gauge theory of gravity, as a corollary
    102. 102. More about Dirac’s spinors Can think of them both ways: - As two electromagnetic waves - As the complex (=quantum) generalization of electromagnetic wave The latter is going to show us the original Dirac theory However the former is much more instructive and useful for our objectives: It is going to show us the connection and unity of gravity and electromagnetism, and hence then the links of gravity and quantum theory by the mediation of electromagnetism
    103. 103. Why is “quantum gravity” a philosophical problem? • Not for Alan Socal’s "Transgressing the Boundaries: Towards a Transformative Hermeneutics of Quantum Gravity“    • But for the need of “transgressing the boundaries” of our gestalt: the gestalt of the contemporary physical “picture of the world”! Thus, our answer when an unsolved scientific problem becomes a philosophical one is: When it cannot be solved in the gestalt of the dominating at present picture of the world despite all outrageous efforts 
    104. 104. Our suggestion to change the gestalt: the physical picture of the world Its essence is: a new invariance of discrete and continual (smooth) mechanical movements and their corresponding morphisms in mathematics This means a generalization of Einstein’s (general) principle of relativity (1918): “Relativitätsprinzip: Die Naturgesetze sind nur Aussagen über zeiträumliche Koinzidenzen; sie finden deshalb ihren einzig natürlichen Ausdruck in allgemein kovarianten Gleichungen.“
    105. 105. An equivalent reformulation of Einstein’s principle of relativity: All physical laws must be invariant to any smooth movement (space-time transformation) Comment: However all quantum movements are not smooth in space-time at all: Even they are not continuous in it Besides: the relativity movements are not “flat” in space-time in general while all quantum movements are “flat” in Hilbert space Definition: A movement is flat when it is represented by a linear operator in the space of movement
    106. 106. Our suggestion the general relativity principle to be generalized: All physical laws must be invariant to any movement (space-time transformation) The difference between Einstein’s formulation and our generalization is that the word “smooth” is excluded so the movement can already be quantum However such a kind of invariance (in fact, an invariance as with the discrete as with the continuous) meets a huge obstacle in set theory: consequently, in the true fundament of mathematics requiring to change gestalt
    107. 107. The huge obstacle in set theory: The invariance of the discrete and continuous cannot be any isometry in principle since the standard measure of any discrete set is zero (while the measure of a continuum can be as zero as nonzero) Moreover, the obstacle is deeper situated in set theory since the power of any discrete set is less than that of any continuum even if its measure is zero Fortunately Skolem’s paradox offer’s a solution, however, “transgressing boundaries” of the “gestalt”: Unfortunately Skolem’s paradox is based on, and necessarily requires the axiom of choice alleged sometimes as “unacceptable”
    108. 108. The inevitability of the axiom of choice in quantum mechanics The axiom of choice in quantum mechanics is well- known as its “randomness” in principle or as the “no-go” theorems about the “hidden variables” (Neumann 1932; Kochen, Specker 1967): Given the mathematical formalism of quantum mechanics (based on Hilbert space), quantum randomness is not equivalent to any statistical ensemble: Its members or their quantities would be the alleged “hidden variables”
    109. 109. The Kochen − Specker theorem is the most general “no hidden variables” theorem: Its essence: wave-particle duality in quantum me- chanics is equivalent with “no hidden variables” in it The most important corollary facts of its: A qubit is not equivalent to a bit or to any finite sequence of bits Bell’s inequalities The inseparability of apparatus and quantum entity The “contextuality” of quantum mechanics Quantum wholeness is not equivalent to the set or sum of its parts; quantum logic is not a classical one
    110. 110. The “quantum wholeness” of the axiom of choice and the “no hiddenness” theorems Preliminary notes: If there is an algorithm, which leads to the choice, the axiom needn’t: Consequently, the axiom core is the opportunity of choice without any algorithm − be guaranteed Given the choice without any algorithm is a random choice in definition, the axiom of choice postulates that a random choice can always be made even if a rational choice by means of any algorithm cannot
    111. 111. The “quantum wholeness” of the axiom of choice and the “no hiddenness” theorems: The “no hidden variables” theorems state that any choice of a definite value in measuring is random: Thus, they postulate the axiom of choice in quantum mechanics How, however, can we explain intuitively the randomness of choice in quantum mechanics? The apparatus “chooses” randomly a value among all probable values by the mechanism of decoherence, e.g. a “time” interpretation of coherent state and decoherence is possible:
    112. 112. The “time” interpretation of coherent state and decoherence: The de Broglie wave periods of the measuring apparatus 𝑻 𝒂 and of the measured quantum entity (𝑻 𝒆) correspondingly: 𝑻 𝒂 = ħ 𝒄 𝟐 𝟏 𝒎 𝒂 ; 𝑻 𝒆 = ħ 𝒄 𝟐 𝟏 𝒎 𝒆 ; ∴ 𝑻 𝒂 𝑻 𝒆 = 𝒎 𝒆 𝒎 𝒂 ≈ 𝟎 Consequently, coherent state corresponds to 𝑻 𝒆, and decoherence to 𝑻 𝒆 𝑻 𝒂, i.e. − to a random choice of a (≈) point among the continual interval of 𝑻 𝒆 Now, we can explain the difference between a coherent state and a statistical ensemble so: 4 1
    113. 113. The “time” interpretation of the difference between a coherent state and a statistical ensemble A discrete (quantum) leap of any function in a point (an argument value) generates a coherent state. For the so-called time interpretation we may accept the argument be time A continuous function (e.g. of time) generates a statistical ensemble (e.g. of the measured values in different time points) The transformation between a discrete leap and a continuous function implies the corresponding transformation between a coherent state and a statistical ensemble

    115. 115. A few comments: the first one: wave-particle duality as invariance After Niels Bohr we are keen to understand duality as complementarity: The two dual aspects or quantities cannot be together (e.g. measured simultaneously) However according to the true formalism of quantum mechanics − based on complex Hilbert space, they should be equal: Hence, the dual aspect of quantity is merely redundant In fact, the “no hidden variables” theorems imply the same: So we should speak of wave-particle invariance. In particular, our intuition distinctly separating waves from particles misleads us: They are the same in principle
    116. 116. A second comment: wave-particle inva- riance embedded in complex Hilbert space Two important features of complex Hilbert space allow of such embedding in it: (1) It and its dual space are anti-isomorphic (Riesz representation theorem); So (1) allows the following: The four pairs can be identified: (1.1) the two corresponding points of the two dual space; (1.2-3) the Fourier transformation and its reverse one of the probability distribution of a random quantum quantity and its reciprocal one (these are two pairs); (1.4) any quantum quantity and its conjugate one. Besides, (1.5) any point in Hilbert space can be interpreted as a function as a vector
    117. 117. A necessary gloss about the probability distribution of a random quantum quantity: The probability distribution of a “classical” random quantity is a real function of a real argument. If however any point in Hilbert space is interpreted as a probability distribution of a random quantum quantity, we need a complement gloss about the meaning both of a complex probability and of a complex value as to a physical quantity. Our postulate: any quantum quantity and its probability distribution is composed by two “classical” ones and their probability distributions sharing a common physical dimension: one for the discrete and another for continuous aspect
    118. 118. A short comment on the postulate: Consequently when we measure a quantum quantity, we lose information Any quantum probability distribution is reduced to a statistical ensemble The principle of complementary forbids the question about the lost information The most natural hypothesis is that as the two components as their corresponding probability distributions coincide This conjecture founded by the axiom of choice in quantum mechanics adds wave-particle invariance to wave-particle duality
    119. 119. More about the embedding of wave- particle invariance in complex Hilbert space That multiple identification can be complemented more: It identifies a generalized (e.g. ∆-function) and “ungenerelized” function 𝑓 (e.g. a constant). We can interpret it as 𝑓−1 ↔ 𝑓, or as the interchange between the set of arguments and that of values, or as the interchange of the “axes” of Cartesian product. Note that is an anti-isometric 𝜋 2 rotation. The same physically interpreted is the wave-particle invariance in question. The really necessary condition of it is only Skolem’s “paradox”. However whether is not the last also a sufficient condition for it?
    120. 120. A set-theory generalization of wave- particle invariance Let us introduce the set of qubit integers ℚ: Any integer is generalized as a numbered qubit: The set of qubit integers ℚ is isomorphic to complex Hilbert space ℍ. According to the well-ordering theorem (an equivalent of the axiom of choice) Hilbert space ℍ is isomorphic to the set of integers 𝕀 by means of the set of qubit integers ℚ: Now already, the equivalence of Skolem’s paradox and wave-particle invariance can be considered as that isomorphism: ℍ ℚ 𝕀 4 3
    121. 121. Another useful, now physical interpretation of the invariance (duality) Given the wave-particle invariance (duality) as the two (possibly coinciding) points of the dual anti-isomorphic Hilbert spaces, it admits one more inter- pretation:  as a (“covariant”) set of harmonics as a (“contravariant”) set of points, the two sets being anti-isomorphic (anti- isometric measurable) 4 4
    122. 122. Another useful, now physical interpretation of the invariance (duality) Formally, we can yield that interpretation by another physical interpretation of a function and its Fourier transformation: 𝑓 𝑥 𝐹𝑜𝑢𝑟𝑖𝑒𝑟 F 1 𝑥 𝑝ℎ𝑦𝑠𝑖𝑐𝑎𝑙 𝑖𝑛𝑡𝑒𝑟𝑝𝑟𝑒𝑡𝑎𝑡𝑖𝑜𝑛 𝑓(𝑡) 𝐹𝑜𝑢𝑟𝑖𝑒𝑟 𝐹 1 𝑡 4 4

Of course, does one wish, both spaces could be curved, and a partial degree of entanglement might be combi- ned with a corresponding partial degree of gravity 7 1

    156. 156. The quadrilateral “two by two”: Hilbert – Banach, and Minkowski – pseudo- Riemannian space: conclusion The close analogy between those two sides of the “quadrilateral” hints their common essence as two different ways for expressing the same: Banach (Hilbert) space as functions globally, and pseudo-Riemannian (Minkowski) space as point trajectories locally
    157. 157. A few important notes: on the conclusion Banach (Hilbert) space represents the same as functions globally, and pseudo-Riemannian (Minkowski) space as point trajectories locally The first earnest note: The time (instead of “frequency”) interpretation of pseudo-Riemanian (Minkowski) space is due only to tradition or from force of habit: In fact, both Banach (Hilbert) and pseudo-Riemannian (Minkowski) space are invariant to time – frequency, or continuous – discrete interpretation, or wave – particle duality as mere mathematical formalisms
    158. 158. A few important notes: on the conclusion Banach (Hilbert) space represents the same as functions globally, and pseudo-Riemannian (Minkowski) space as point trajectories locally The second earnest note: Both pseudo-Riemanian (Minkowski) and Banach (Hilbert) space are well-ordered in the parameter of either time or frequency in (geodesic) line. However what is up if the well-ordering is abandoned in all cases eo ipso abandoning the axiom of choice?
    159. 159. A few important notes: on the conclusion Banach (Hilbert) space represents the same as functions globally, and pseudo-Riemannian (Minkowski) space as point trajectories locally The answer is the third earnest note: Abandoning the axiom of choice in all the cases eo ipso well-ordering, the whole becomes a coherent mix of all its possible states or parts (well-ordered in time or in frequency before that ). Any possible state or part can be featured by its probability to happen. We can illustrate that probability as the obtained by projection number or measure of the corresponding state or part
    160. 160. The fourth earnest note on the conclusion Banach (Hilbert) space represents the same as functions globally, and pseudo-Riemannian (Minkowski) space as point trajectories locally Function space The “curved” case The “flat” case “Line” space “Projection in probabilities” space A point in Banach space A point in Hilbert space A line in pseudo- Riemann. space t f A trajec- tory in a force field A tra- jec- tory A line in Minkow- ski space −∞ ∞ 𝒑𝒅𝒙 < 𝟏 p x A normed probability distribution −∞ ∞ 𝒑𝒅𝒙 = 𝟏 p x A defected probability distribution being due to entanglement (the force field) 7 7
    161. 161. A “homily” about negative probability The defected probability distribution being due to entanglement (i.e. to an interrelation) can be also interpreted as an alleged substance featured by negative probability. However that requires for quantum wholeness to be transformed into an “equivalent” statistical ensemble. If doing so, we can consider entanglement as a new kind of substance: the substance of quantum information
    162. 162. The sides of the quadrilateral one by one: 3) Hilbert – Minkowski space Both spaces are “flat”, well-ordered, expressing the same, but: A real difference: Hilbert space is a function space, while Minkowski space is an ordinary, “point” space An alleged difference: Besides, Hilbert space is interpreted (but incorrectly) only as a “frequent” space representing discrete impulses, while Minkowski space (but also incorrectly) only as a “time” space representing smooth trajectories. In fact, both spaces are equally interpretable as a “time”, as a “frequent” space connected by a Fourier or Fourier-like transform
    163. 163. The sides of the quadrilateral one by one: 3| Hilbert – Minkowski space videlicet: Hilbert space is a function space, while Minkowski space is an ordinary, “point” space: A very important corollary from the real difference, So that a trajectory in Minkowski space represents a potentially infinite, current process in time or “in frequency”, while a point in Hilbert space represents the same process as complete or as an actual infinity The two views mentioned before on a single “Hilbert- Minkowski” space represent it correspondingly as a potential infinity and as an actual infinity
    164. 164. The sides of the quadrilateral one by one: 4|Banach – pseudo-Riemannian space Both spaces are “curved”, and all the rest said about Hilbert – Minkowski space is valid to their pair, too: Both spaces express the same in different perspectives: Both spaces can be interpreted as a time as a frequency space, but the Minkowski space represents a process in potential infinity as a world line in an ordinary, “point” space, while Hilbert space an actual infinity as a complete result, namely as a point in a function space

    167. 167. The juxtaposition of Lagrange and Hamilton approach to mechanical movement: conclusion A. Both approaches are equivalent in classical mechanics – a well-known fact B. If we accept the equivalence of gravity (Lagrange) & entanglement (Hamilton), both approaches will be immediately equivalent in quantum mechanics, too C. The universal equivalence of both approaches origins from discrete-continuous invariance, or from wave-particle dualism, or from Skolem’s “paradox”, or in last analysis – from the axiom of choice
    168. 168. A little philosophical digression about gravitational field and force field
    169. 169. A new conjecture: entanglement field If any ordinary field acts to the values of certain physical quantities, the entanglement field acts to the probabilities of those values: So it can be called so: probability field The source of probability or entanglement field can be any discrete, jump-like change of the same quantity in any point of space-time. It can act upon any other discrete change of that quantity anywhere: However how?
    170. 170. How can entanglement field act? Its origin is rather mathematical and universal for that: Any discrete, or jump-like change is equivalent to a probability field in a sense: Since a definitive speed of change is impossible to determine, it is substituted by all the values with certain probabilities or in other words, by the probability field of all the values. If there are two or more discrete changes, they can share some values with different probabilities in each probability field generated by a quantum leap. In the last case, a common and equal probability calculable appears instead of the two or more different ones
    171. 171. How can entanglement field act? Next: If and only if the probability is zero for each other field where the probability of one of them is nonzero, then the probability fields do not interact, they are “orthogonal” and no entanglement If there is entanglement, it “happens” mathematically by means of the pair of dual spaces: How? Firstly, we should interpret the connection between the two dual spaces

    175. 175. A digression about the “arrow of time” The “arrow of time” is a fundamental, known to eve- ryone, but partly explainable fact about time unlike all other physical quantities, which are isotropic Our simple and obvious explanation is the following: Time is the well-ordering of any other physical quan- tity. The “arrow of time” and the “well-ordering” are merely full synonyms expressing the same Consequently, the axiom of choice, which is equivalent with well-ordering, means that any set can be represented as a physical quantity in time or as a trajectory in a special space corresponding to that set: Or in other words, the set can always be transformed into another set. The theory of categories states generalizing that even if the “set” is not a set, but a “category”, it can be transformed
    176. 176. Three restrictions of choice for a trajectory point The dependence of momentum on position: The value of momentum in a moment is proportional the position derivative in the same moment, i.e. to the value of speed The “smooth choice” of both momentum and position: The choice of the trajectory following point is restricted to an infinitely small neighborhood of the point, so that the trajectory and its derivative are smooth in any point The exact correspondence of the measure of the same value set with the value probability
    177. 177. The same restrictions of choice for the same trajectory point as a field point Any trajectory point undergoes a force being due to the field in the same space-time point That force represents merely a second and different trajectory but only in the dual space of energy and momentum. Such a second energy-momentum trajectory is determined to any possible space-time trajectory There is a single difference: The first restriction is absent: Position and momentum are independent of each other for the second trajectory: However the other two restrictions are valid!
    178. 178. An interpretation of both trajectories in terms of whole and part The first trajectory represents the case without any force field, including gravitational one. The system is closed as if it was alone in the universe and its mechanical energy is only kinetic. That is the case where a part is considered as the whole. The second trajectory represents the universe, or the whole including the first system as a part (subsystem). It is closed, too, really alone, and which is the source both of the force field and of the potential mechanical energy
    179. 179. The interaction of a system with a force field in terms of whole and part The energy-momentum of the system interacts with the energy-momentum of the field in the same space-time point as adding 4-vectors in Minkowski space We can interpret that as forming a new whole of two previous wholes. The whole of the universe includes the whole of the system in consideration. We have also discussed such an operation as “set-theory curving” as inverse to a “flattening” choice according to the axiom of choice
    180. 180. A view on a system in a force field in terms of frequency (energy) instead of time The energy-momentum representation is that viewpoint. Any force field, which comprises a system, represents a mismatch of the discrete and continuous aspect of the system By tradition that mismatch is embedded in energy- momentum or in other words, in terms of frequency and discrete impulse In fact, it represents the impact of the whole or of the environment onto the system, and it is equivalently representable as in terms of frequency and discrete impulse as in those of time and smooth trajectory
    181. 181. Einstein's general relativity revolution represented in the same terms Since any force field including gravitational one can be equivalently represented as a second but space-time for and instead of energy- momentum trajectory, that second trajectory can be considered as the basis of a “curved”, namely pseudo-Riemannian space, in which the first trajectory of any partial subsystem happens. The space comprises trajectory as a space- time expression of the way, in which any whole comprises any part of its
    182. 182. The deep meaning is not in the geometrization of physics, i.e. not in the representation of a force field as a “curved” space-time, namely pseudo- Riemannian space The real meaning is in the equivalence of the two representation of any force field: as a second energy-momentum space (or trajectory) as a second space-time (or trajectory) However, let us emphasis it, both representations are not only continuous but smooth (in fact, in tradition)
    183. 183. Following Einstein’s lesson beyond him: … we introduce a second representation, namely that “from eternity” rather for a new equivalence (or “relativity”) than only for it itself That “relativity” or equivalence is between the discrete and the continuous (smooth) And the second representation, which is from the “viewpoint of eternity” merely removes the well- ordering in space-time (energy-momentum) eo ipso removing the axiom of choice, and eo ipso the choice itself That second representation is … quantum mechanics
    184. 184. A view on a system in a force field in terms of eternity instead of time … OK, but we have already introduc ed it a little above 8 3
    185. 185. Note, please, an amazing property of that “relativity” … self-referentiality Particularly, duality offers a new model of double referentiality as self-referentiality: Both the dual (e.g. spaces) can be considered as a generalization of each other if each of the two dual (e.g. spaces) is equivalent to the ensemble of the two ones: Besides that ensemble is as the generalization as the equivalent of both of them The “flat” Hilbert space of quantum mechanics with its principle of complementarity is a good example for that kind of self-referentality
    186. 186. A few remarks on that amazing kind of self-referentiality Totality, infinity, and wholeness should possess the same property: Consequently, the ensemble of two dual (e.g.) spaces would be an appropriate model of any of them, and quantum mechanics using the same model can be considered as an empirical (note!) science of all of them! There are at least a few important interpretations of the same idea in physics, mathematics and philosophy: The ensemble of 'things' and their 'movements' is dually complete in the sense above
    187. 187. A few remarks on that amazing kind of self-referentiality ... besides, the ensemble of functors and categories in category theory is dually complete; the ensemble of proper (without the axiom of choice) and improper (with the axiom of choice) interpretation in set theory, too; Truly said, we refer to that self-referentiality (again) for the pair of the eternity ("no axiom of choice") and time (by the axiom of choice) view to mechanical movement
    188. 188. The most essential remark on the dual self-referentiality of eternity and time Our problem is the dual self-referentiality of: View from 𝒆𝒕𝒆𝒓𝒏𝒊𝒕𝒚 𝒕𝒊𝒎𝒆 𝑵𝒐 𝒄𝒉𝒐𝒊𝒄𝒆 𝑨𝒙𝒊𝒐𝒎 𝒐𝒇 𝒄𝒉𝒐𝒊𝒄𝒆 view Our solving is going to be: Eternity and time are merely two different interpretations of the same mathematical structure: namely, Hilbert (Banach) space
    189. 189. Be eternity and time two different interpretations, then … … frequency (energy), time and eternity are three equivalent interpretations; … eternity interprets Hilbert (Banach) space as a dual (double) probability distribution and its Fourier(-like) transform; ... time interprets Hilbert (Banach) space as Minkowski (pseudo-Riemannian) space and movement as a smooth trajectory; ... frequency (energy) interprets them as representations of a discrete impulse; …
    190. 190. Be eternity and time two different interpretations, then … … we should admit the equivalent curvature (i.e. the nonorthogonality) as between eternity and time as between time and frequency (energy) as between frequency (energy) and eternity, and as between all of them; … as entanglement (from the particular view of eternity) as gravity (from the particular view of time and energy) as any equivalent combination of them expresses the same; … we should admit even an interaction between entanglement and gravity
    191. 191. Be eternity and time two different interpretations, then … … that which is the same but expressed differently by gravity (in terms of time and energy) and entanglement (in terms of two probability distributions) represents the same interaction between a system and the universe (environment), in which it is included, from the two viewpoints of time (and energy) and eternity … whatever about the eventual interaction of gravity and entanglement is a quite open question
    192. 192. Be eternity and time two different interpretations, then … Well-ordering in time and frequency (energy) by the axiom of choice Complex Hilbert (Banach) Space Wave function as a Fourier transform of two (conjugate) probability distributions eternity time& frequency for entanglement for gravita- tional field The Same!!! 8 4
    193. 193. Consequently, our conclusion is ... !!! Entanglement is a view on a system in a force field in terms of eternity instead of time (or frequency, energy)
