Subject: On Einstein and realism
Date: Thu, 03 Feb 2005 15:24:17 +0200 From: Dimi Chakalov <dimi@chakalov.net> To: Charles Tresser <charlestresser@yahoo.com> CC: Michael Clover <michael.r.clover@saic.com>, Tim Palmer <tim.palmer@ecmwf.int>, Ezra Newman <newman@pitt.edu>, Itamar Pitowski <itamarp@vms.huji.ac.il> Dear Dr. Tresser, May I comment on the issue of "alternatives" in the EinsteinBohr debate [Ref. 1, p. 1]: Either (i) the description by means of the [psi]function is complete, OR (ii) the real states of spatially separated objects are independent of each other. It seems to me that there is a third possibility which can be unraveled by zooming on the notion of 'counterfactual definiteness', an implicit assumption in the proof of Bell's theorem [Ref. 2]. You define counterfactuals as "thought experiments that cannot be performed because performing them would violate Physics (like getting back in time to redo an experiment)" [Ref. 1, p. 5]. Hence for two (EPR paradox) or more entangled parties (we cannot write down their "individual" properties as tensor products), the line of reasoning includes  tacitly or not  'counterfactual definiteness' [Ref. 2]. The latter is wellknown in psychology, http://www.Goddoesnotplaydice.net/Vecchi.html Please note that the kind of *reality* of entangled parties, in the example at the link above, is a Platonic reality. It contains "counterfactual" or potential states *en bloc*, hence is UNspeakable. We keep this *potential reality* in our brains, but it is not included in presentday QM textbooks. More at http://www.Goddoesnotplaydice.net/Maximilian.html#brain The late Asher Peres never agreed to comment on this *potential reality*. I believe it introduces a brand new kind of determinism in the quantum realm, which is missing in QM textbooks. Surely Einstein and Bohr would have been very happy to see it in math. I hope to hear from you and your colleagues. Will keep your professional feedback strictly private. Kindest regards, Dimi Chakalov

However, in order to establish Bell’s theorem, we need to consider correlations between pairs of measurements when the magnets have different orientations, let’s say n for the lefthand magnets and n' for the righthand magnets. "It is also necessary to assume that it is meaningful
to ask: what would the spin of a lefthand particle have been had we actually
measured it with magnets oriented in the n' direction (or, conversely,
what would the spin of the righthand particle have been had we actually

================ Subject: Request for references
Dear Dr. Szabados, I have an immodest request. I need references and any other information regarding (i) all nontensorial variables in GR (Noether currents inclided), (ii) the nature of the resulting "nonlocality" in GR, and (iii) the comparison of the "nonlocality" in GR with the apparent nonlocal interactions in QM due to quantum entanglement. The task is to get (iii) done. In your online article "QuasiLocal EnergyMomentum and Angular Momentum in GR: A Review Article" from 16 March 2004 [Ref. 1], you explained the meaning of the nontensorial Christoffel symbols and the linear connection. I don't understand GR (the linear approximation of Einstein's theory [Ref. 2]) and cannot compare the quasilocality in GR with the nonlocal interactions in QM, as you can see from my unsuccessful efforts at http://www.Goddoesnotplaydice.net/Oriti.html#Erich http://www.Goddoesnotplaydice.net/Nerlich.html#note http://www.Goddoesnotplaydice.net/Rosinger.html In general, I really need to understand GR, since I can't see any *genuine observables* whatsoever [Ref. 3] nor some rigorous proof that the spacetime can indeed be 'asymptotically flat' [Ref. 2] so that I can make some sense of that nontensorial mesh. I extend my request for references to all colleagues of yours. Please be assured that I'll keep your feedback strictly private and confidential, and please excuse my violent curiosity. Kindest regards, Dimi Chakalov

However, the successes discussed in the previous subsection show that the global gravitational energymomenta and angular momenta are useful notions, and hence it could also be useful to introduce them even if the spacetime is not asymptotically flat. Furthermore, the nontensorial nature of an object does not imply that it is meaningless. For example, the Christoffel symbols are not tensorial, but they do have geometric, and hence physical content, namely the linear connection. "Indeed, the connection is a nonlocal geometric object,
connecting the fibres of the vector bundle over different points of the
base manifold. Hence any expression of the connection coefficients, in
particular the gravitational energymomentum or angular momentum, must
also be nonlocal. In fact, although the connection coefficients at a given
point can be taken zero by an appropriate coordinate/gauge transformation,
they cannot be transformed to zero on an open domain unless the connection
is flat."

Note: On Wednesday, 23 February 2005 at 17:37:02 +0100 (CET), Laszlo Szabados was very kind to send me a summary of the nontensorial variables in GR (cf. below). He stressed that "the gravitational energymomentum and angular momentum, i.e. the gravitational analogs of the classical conserved quantities and observables are nonlocal. Nonlocal in the sense that they should be associated to *extended* domains rather than to points." He went further by emphasizing that "the nonlocality in QM is a completely different business. The root of this is that the basic object, the wave function, by means of which the elementary states are described is already an "extended" mathematical objects. This comes from the different nature of the notion of the states and the dynamics of the two theories." Hence if we wish to compare the "nonlocality" in GR with the apparent nonlocal interactions in QM due to quantum entanglement, as stated in my email above, we should provide some new notions of the states and the dynamics of the two theories. Clearly, we're about to enter the realm of quantum gravity, so don't expect to read something that can be found in QM and GR textbooks. Also, don't expect to find any math here. The issue is highly speculative, since "even if we start with genuine tensorial variables, then certain important physical quantities turn out to be nontensorial" (Laszlo Szabados). Right. So, we need to elaborate some new notions of the states and the dynamics of the two theories, such that they can be presented, with minor distortion, as 'quantum entanglement' in the context of QM, and 'nontensorial quantities' in the context of GR. Something like a song being played with two entirely different instruments, QM and GR. But the "song" itself should be different from any of its QM and GR presentations, because it must provide the common dynamics of a quantumgravitational system. Again, please don't reject the speculations below with 'there is no such thing in QM nor in GR'. Of course there isn't. I am trying to speculate on quantum gravity, but will provide only the links to what has been already suggested. And, as you might have already guessed, the "song" itself will be derived from the physics of the human brain. Regarding the human brain dynamics, see the alleged "nontensorial" variables expressed as 'context' here. Note that what we call 'context' is "spread over" the whole text. Thus, the 'context' is nonlocal in the sense that it should be "associated to *extended* domains rather than to points" (Laszlo Szabados). More from Chris Isham here. In QM, this nonlocal 'context' comes from the Holon, but it cannot be used for sending information fasterthanlight, and "the field equations are still genuine partial differential equations" (Laszlo Szabados). Now comes the tough part. What is the proper time associated with the Holon and its 'context'? What is the intrinsic dynamics of the Christoffel symbols, namely, in what time do they change? And what could be the common dynamics of a quantumgravitational system? Regarding the first question, see the explanation of the notion of 'global mode of spacetime' by reductio ad absurdum here. (Some implications can be read here.) The dynamics is explained with the established notion of 'relational reality' here, and with the proposed notion of 'donkian Hamiltonian' here. (To get a glimpse of the dynamics of the human brain, click here and here.) As to the second and the third questions, the situation is quite murky, to say the least. Perhaps Laszlo Szabados and Elemer Rosinger can shed some light on the intrinsic dynamics of the Christoffel symbols. I believe they can be interpreted as produced by the Holon, too. In general, the notion of the Holon can be explained as 'something that pertains simultaneously (global mode of spacetime) to all elements of a set'. Hence the Holon introduces 'quantum wholeness', such that all elements of the set are both ONE (covered by the context delivered by the Holon) and 'many'. In GR, the Holon manifests itself by those nontensorial variables. But the whole idea of representing matter by a tensor was "a wooden nose in a snowman", as stated by Einstein. Maybe we should try to mimic Feynman's path integral approach to QFT by elaborating some 'virtual geodesic path' formulation of Einstein's GR, which would include two virtual worlds in the global mode of spacetime, and a real, localized, strictly tensorial world in the local mode of spacetime. This will be an ambitious goal, and if you wish to start with some "extension" of QM, see Erasmo Recami's quantph/9706059 here. I was never able to understand Einstein's
GR, and I am very grateful to Laszlo Szabados for his efforts to help
me with the nontensorial mesh in GR. Read about it below.

============== Note: I was asked by a colleague to explain the idea of 'virtual geodesic path' (VGP) formulation of Einstein's GR. In the notes above, I tried to explain what I mean by 'virtual' in QM and GR: a unified approach to nonlocal interactions, which might (hopefully) provide a framework for canonical quantum gravity. Very briefly, I denote with 'virtual' both the Wheeler cloud and all nontensorial variables in GR. This is something like a song being played with two very different instruments, as you can see by comparing the mathematical presentation of the virtual "stuff" in QM and GR. Surely this is "one song" played by Mother Nature, but it seems to me that a direct comparison of the nonlocal virtual stuff in QM and GR is not possible: the math is totally different, and we need new ideas about some 'common denominator'. But before jumping into the putative
global
mode of spacetime, let's see if we can get the job done without it.
This was the reason for writing to Charles

I received today a complaint that my interpretation of 'virtual stuff' in QM has not been made clear and decisive. Let me address this complaint here, ensuing from the interpretation of the "collapse" by J. von Neumann. Then I will try to explain my speculation about how this same virtual stuff shows up in GR, in the form of some 'dark stuff', following the metaphor 'one song being played with two entirely different instruments'. Again, consider the issue of relativistic "collapse", after I. Bloch. The reason why we cannot, even in principle, work out a theory of Lorentz invariant nonlocality has been outlined here. Recall that after the socalled collapse or Process I (von Neumann), the pure state density matrix transforms "instantaneously" into a mixture, but for a given quantum system only one component of the mixture is available to ponder on. Also, the wave function of the initial quantum system can be made to cover the whole "asymptotically flat" (I love this phrase) 3D space, i.e., its support can be unbounded. Let's suppose, just for the sake of the argument, that the global mode of spacetime does not exist, and try to find out the link between the Hilbert space and Minkowski spacetime without it. In other words, let's drop the postulate of 'global mode of spacetime', and assume that a relativistic collapse was possible to occur in Nature. This means that you could, at least in principle, equate/map the "time parameter" in Schrödinger equation (Process II, von Neumann) to the time parameter in STR, and because the latter is Tinvariant, you would be able to trace back the initial state of the quantum system before the collapse. That is, after you perform the measurement, you will be able to trace the history of the quantum system back to its state "immediately prior" the collapse, and then nothing could possibly stop you to trace the entire "history" of the quantum system back to the last instant from its lifetime, as we know from quantum cosmology. Hence you could discover some time operators in QM, as well as the absolute reference frame in which the collapse "occurs" and its absolute cosmological time. You will also wipe out the KochenSpecker theorem, because your quantum system would have fixed state which is independent from the measurement context: your quantum system will behave just like a classical system, say, the Sun. Last but not least, you will establish a direct link between the time parameter read by an inanimate physical clock and the intrinsic "time" of the interference pattern of thecatisaliveanddeadatthesametime in Wigner distribution presentation, hence mapping the negative probabilities of the global mode of spacetime with the observable physical world ascribed to positive probabilities (cf. Dietrich Leibfried, Tilman Pfau, and Christopher Monroe, Shadows and mirrors: Reconstructing quantum states of atom motion, Physics Today 51(4), 2228 (1998); 2.7MB pdf file from here). Surely this is impossible, which leaves us with a number of puzzles and painful questions. Shall we say, after Niels Bohr and Asher Peres, that there is no quantum world and "quantum states are not physical objects: they exist only in our imagination"? That nuclear bombs are product of our imagination? Of course not. But then you say  look, I can make a relativistic QM from Process II, by replacing the Schrödinger equation with the Dirac equation. But of course you can, Harry. You can even develop a whole standard model of elementary particles, only you won't get any closer to solving the mystery of the quantum world, as known since 1935, after Schrödinger's "Die gegenwärtige Situation in der Quantenmechanik". The whole issue is about the nature of quantum reality. It's a virtual reality. There is no other way to bridge the gap between the Hilbert space (there is no Hilbert spacetime) and Minkowski spacetime. Which brings us to the nature of time, again. The same line of reasoning applies to the socalled dark matter and dark energy. They too are 'virtual stuff', as I tried to explain here and here. But then you say  hold on, GR is a classical theory, there is no room for any virtual stuff in it. Yes there is, only it is being 'played with a completely different instrument': the principle of general covariance. Recall the lesson from the hole argument, and read P. Bergmann [Ref. 3] and R. Geroch on 'diffeomorphism freedom' here. It may be quite difficult, if not painful, to consider the possibility that diffinvariant "observables" are being selected from a virtual stuff that lives 'outside spacetime', but the other option is to search for 96 per cent of the universe that remains in some "dark" state. Alternatively, it may not be "dark matter" and "dark energy" but a virtual reality. In summary: If you honestly believe that GR does not need a crucial update, then you of course are entitled to interpret the "dark" stuff as matter and energy. Fine. But then you'll have to accommodate this whole dark stuff in the current GR  your way. Just recall the cosmological constant problems, and quit. It's hopeless, because with the current GR and QFT you will have to chose between mutually exclusive solutions, while Mother Nature has managed to employ all of them, by answering your questions with Jain. Not sure? Okay, wait for the paper by Hooft 't G., entitled: "201 wrong theories for the cosmological constant" (in preparation). Prof. Gerard 't Hooft kindly wrote to me "you are wellcome to provide for the 201st reference in my paper", and I immediately sent him the link to my web site. Should you have further questions on the virtual reality in QM and GR, please consider requesting the opinion of Prof. Gerard 't Hooft as well. He is a Nobel Prize laureate, while I'm just a psychologist. He has written a textbook in GR which looks totally clear and decisive, while I stick to the opinion of Einstein, in his last lecture of April 14, 1954 (reference here): "The representation of matter by
a tensor was only a fillin to make it possible to do something temporarily,
a wooden nose in a snowman."

Dear Professor Newman, I have *great* faith in your Hspace [Proc. R. Soc. A363 (1978) 445], http://www.Goddoesnotplaydice.net/Tresser.html#note Perhaps R. Penrose couldn't make
use of it because was guided by wrong ideas. If you wish to explore the

Explanatory Note: There is no rational reason why I believe in Ted Newman's Hspace (E.T. Newman et al. (1978), The metric and curvature properties of Hspace, Proc. R. Soc. A363, 445). I have just a hunch that he has discovered the correct presentation of the "fine structure" of what we call "point". Let me try to explain. If we introduce a timeless global mode of spacetime, which we "insert" between two "neighboring" points from the local mode of spacetime (read the hypothesis here), then it seems to me that the fine structure of the "points" in the local mode will display two virtual worlds with inverted spacetime basis. These two virtual worlds look like material and tachyonic, and are "separated" by a luxonic timeless entity, the remnant from the global mode of spacetime. Think of this remnant as a water lily which is almost completely open. This is a vivid image of a "point" from the global mode of spacetime, presented  or shall I say "collapsed"?  to some 'asymptotically flat spacetime' of the local mode of spacetime. The leaves of the lily display Ted Newman's Hspace. They facilitate the timeless negotiation of the "point" with 'everything else in the universe', in line with the rule 'thing globally, act locally'. Recall the postulate that in the global mode of spacetime the whole universe is in a special ONE state called Holon. Now, close the leaves of the lily, and they will form an arrow toward the next 'end point' along the putative universal time arrow. Hence you can think of the universal time arrow as a chain of states of the lily: open (asymptotically flat local mode of spacetime), then closed (the transition in the gaps in the global mode of spacetime), then open, closed, etc., ad infinitum. Every time you see the water lily open, you have one state (or jacket) that has already been negotiated with 'the rest of the universe', according to the principle of relational reality, while the rest of potential (cat) states are temporary "eliminated" with negative probabilities and remain in the global mode of spacetime, patiently waiting to take part in the negotiation of the next step. The negotiation of the state of a given quantum system with 'the rest of the universe' is the mechanism of the 'chooser' in the quantum realm, and its final stage (open lily) is fully deterministic, because the Holon is ONE entity, and hence can explicate only one state. It just doesn't play dice, because all subsystems in the universe can have only one negotiated state in the local mode of spacetime, which complies with 'everything else', in line with the rules of 'relational reality'. It is quite a different matter that we cannot know the states of all subsystem in the universe, and hence our description of this negotiation process in the global mode of time will be inevitably incomplete, hence will display some "probabilistic touch" in computing the relational state of a given quantum system valid for a given instant from the universal time arrow. I believe Einstein would have been be happy with this purely epistemological uncertainty. Now you will probably say  but where's the math? Sorry, there is still no math here, because we don't know how to model the relational reality in GR. But if you are psychologist, take a look at Ted Newman's Hspace in E.A. Rauscher and R. Targ (2001), The Speed of Thought, J. Sci. Exploration, 15(3), 331. Also, if you are familiar with Chi, perhaps you may wish to see some nice clips by Miroslaw Magola. If you don't know what is Chi and say 'I don't believe in that crap', recall another modification of the inertial mass here. To sum up, if you insist on math, you have a choice. Try Ted Newman's Hspace or wait for the paper by G. 't Hooft "201 wrong theories for the cosmological constant" mentioned above. Needless to say, my hunch about Ted
Newman's Hspace could be wrong. But if we don't leave for India, how can
we discover America?
