Einstein was writing all this before modern quantum theory. Today we know that the Aether is the quantum vacuum filled with virtual particles that are off mass-shell i.e. E^2 =/= (pc)^2 + (mc^2)^2 Also contact forces are caused by off-mass shell virtual photons in the non-radiative near field including longitudinal polarizations absent in real photons on the mass shell (light cone). Action at a distance is in the Wheeler-Feynman classical sense confined to the photon mass shell (aka light cone) but including advanced back from the future destiny waves generalized to "confirmation" quantum de Broglie waves by John Cramer in his TI. This is in addition to the more familiar retarded history waves. de Broglie waves are faster than light in phase quantum information when m =/= 0 though slower than light in energy transport. nonlocal EPR correlations are explained by retrocausal advanced confirmation destiny waves in the Feynman zig zag (term coined by O Costa de Beauregard).

"Thanks Basil for this clarification. It is true that Bohm's original motivation was a realist (as opposed to instrumentalist, Bohrian interpretation). I should have been more clear about that. But it rather quickly became a path to resolving the measurement problem -- if not for its original author(s), certainly for those who have championed it since then.
Also, regarding the quote ["What I felt to be particularly unsatisfactory was the fact that the quantum theory had no place in it for an adequate notion of an independent actuality-i.e. of an actual movement or activity by which one physical state could pass over into another".] This is a key component of the measurement problem.  Also, let me take the opportunity to note that it is not necessary to  identify a 'realist' view of qm with the existence of  'hidden variables'.  I have been proposing a realist view that does not involve hidden variables -- but it does involve an expansion of what we normally like to think of as 'real'. The usual tacit assumption is that
'real' = 'existing within spacetime'  (and that of course requires 'hidden variables' that tell us 'where' the entity lives in spacetime, or at least identifies some property compatible with spacetime existence)" (end-quote)

Me: We all seem to agree that the idea that "real" must be "local in spacetime" is false. Q is real, but it is generally not a local BIT field in 3D + 1 spacetime when there is entanglement. Oddly enough the macro-quantum coherent signal Q in spontaneous breakdown of ground state symmetry is local in 3D+1 but it is generally coupled to nonlocal micro-quantum "noise."

Ruth "In contrast, I think PTI provides us with a realist concept of an independent actuality -- a "movement or activity by which one physical state could pass over into another". "

Me: So does Bohm's ontological interpretation.

Ruth: "But that 'actuality' is rooted in potentiality, which is a natural view given the mathematical properties of quantum objects."

Me: Seems to me you are playing with nouns replacing one vague metaphysical notion with another. What is "potentiality"? Mathematically it's Bohm's Q - perhaps extended to Yakir Aharonov's weak measurements with advanced Wheeler-Feynman back from the future post selection in a post quantum theory with Antony Valentini's "signal nonlocality". Some think that violates the Second Law of Thermodynamics. However, since it only obtains in open systems that is not so. Furthermore our actual universe, the causal diamond bounded by both the past and future horizons is an open system out of thermal equilibrium.

Ruth: "So one can give a  realist, physical account, but it is indeterministic -- involving a kind of spontaneous symmetry breaking. Given that we already have spontaneous symmetry breaking elsewhere in physics, I think we should allow for it in QM.

Thanks again for the clarification --"

    To the contrary, it has been demonstrated in my opinion. First start with Brian's paper "On the biological utilization of nonlocality" with the Greek physicist whose name escapes me for the moment.

    Second: Lecture 8 of http://www.tcm.phy.cam.ac.uk/~mdt26/pilot_waves.html

    Specifically, how the Born rule depends on violation of the generalized action-reaction (relativity) principle that Q has no sources. Q pilots matter without direct back-reaction of matter on Q.

    In other words, orthodox quantum theory treats matter beables as test particles! - clearly an approximation.

    Obviously signal nonlocality violating no-signaling theorems has a Darwinian advantage. Indeed, without it, entanglement appears as static noise locally. Imagine that Alice and Bob's minds are represented each by a giant macroscopic coherent entangled quantum potential Q(A,B). It would obviously be a survival advantage for Alice and Bob to directly send messages to each other at a distance like the Austraiian aborigines do in the Outback. Now use scale invariance. It's obviously an advantage for separate nerve cells in our brains to do so. Also in terms of morphological development of the organisim - signal nonlocality is an obvious plus, which I think is part of Brian Josephson's message in that paper.


    Subquantum Information and Computation
    Antony Valentini
    (Submitted on 11 Mar 2002 (v1), last revised 12 Apr 2002 (this version, v2))
    It is argued that immense physical resources - for nonlocal communication, espionage, and exponentially-fast computation - are hidden from us by quantum noise, and that this noise is not fundamental but merely a property of an equilibrium state in which the universe happens to be at the present time. It is suggested that 'non-quantum' or nonequilibrium matter might exist today in the form of relic particles from the early universe. We describe how such matter could be detected and put to practical use. Nonequilibrium matter could be used to send instantaneous signals, to violate the uncertainty principle, to distinguish non-orthogonal quantum states without disturbing them, to eavesdrop on quantum key distribution, and to outpace quantum computation (solving NP-complete problems in polynomial time).

This last statement is not correct. Bohmian theory can now be applied to the Dirac particle. You do not have to abandon the particle for Fermions at the relativistic level.

    My work on the ideas that Bohm and I summarised in "The Undivided Universe" have moved on considerably over the last decade. But even in our book, we were suggesting that the particle could have a complex and subtle structure (UU p. 37) which could be represented as a point-like object only above the level of say 10^-8 cm. This comment, taken together with point 2 in our list of key points on p. 29 implies that we are not dealing with 'small billiard balls'. There could be an interesting and subtle structure that we have not explored-indeed we can't explore with the formalism in common use, i.e. the wave function and the Schrödinger equation. This is my reason for exploring a very different approach based on a process philosophy (See my paper arXiv: 1211.2098).

    In the case of the electron, we made a partial attempt to discuss the Dirac particle in our book (UU chapter 12). The presentation there (section12.2) only scratched the surface since we had no place for the quantum potential. However we showed in arXiv: 1011.4033 that if we explored the role of the Clifford algebra more throughly, we could provide a more detailed picture which included a quantum potential. We could then provide a relativistic version of what I call the Bohm model or, more recently, Bohmian non-commuting dynamics to distinguish it from a number of other variants of the model.

    In our approach all fermions could then be treated by one formalism which in the classical limit produced our 'rock-like' point classical particles. Bosons had to be treated differently, after all we do not have a 'rock-like' classical limit of a photon. Rather we have a coherent field. Massive bosons have to be treated in a differently way, but I won't go into that here.

    reference? I have been struggling with that in my dreams.

    We noted the difference between bosons and fermions in the UU and treated bosons as excited states of a field. In this case it was the field that became the beable and it was the field that was organised by what we called a 'super quantum potential'. In this picture the energy of say an emitted photon spread into the total field and did not exist as a localised entity. Yes, a rather different view from that usually accepted, but after all that was the way Planck himself pictured the situation. John Bell immediately asked, "What about the photon?" so we put an extra section in the UU (sec. 11.7). The photon concept arises because the level structure of the atom. It is the non-locality and non-linearity of the super quantum potential that sweeps the right amount of energy out of the field to excite the atom.

    Since the photon is no longer to be thought of as a particle, merely an excitation of the field, there is no difficulty with the coherent state. It is simply the state of the field whose energy does not consist of a definite number of a given hν. A high energy coherent field is the classical limit of the field, so there is no problem there either.

    All of this is discussed in detail in "The Undivided Universe".

    Hope this clarifies our take on these questions.

  • Jack Sarfatti The Brown-Wallace is an interesting paper, but I do not agree with its conclusions. Of course, this is exactly what you would expect me to say! What is needed is a careful response which I don't have time to go into here, so let me be brief. The sentence that rang alarm bells in their paper was "Our concern rather is with the fact that for Bohm it is the entered wave packet that determines the outcome; the role of the hidden variable, or apparatus corpuscle, is merely to pick or select from amongst all the other packets in the configuration space associated with the final state of the joint object-apparatus system." (See top of p. 5 of arXiv:quant-ph/0403094v1). As soon as I saw that sentence, I knew the conclusion they were going to reach. It gives the impression that it is the wave packet that is the essential real feature of the description and there need be nothing else. For us the 'wave packet' was merely short hand which was meant to signify the quantum potential that would be required to describe the subsequent behaviour of the particle. For us it was the quantum Hamilton-Jacobi equation that was THE dynamical equation. The Schrödinger equation was merely an part of an algorithm for calculating the probable outcomes of a given experimental arrangement. ( Yes it's Bohr!) But for us THERE IS an underlying dynamics which is a generalisation of the classical dynamics. Indeed my recent paper (arXiv 1211.2098) shows exactly how the classical HJ equation emerges from the richer quantum dynamics. The term 'wave packet' was merely short hand. There is no wave! This is why we introduced the notion of active information which is universally ignored.

    Well my main concern re photons is coherent states where there isn't a definite number of quanta. Perhaps this has

    and also the critique of Brown and Wallace that I mentioned earlier is a significant challenge for Bohmian approach. What
    B & W point out is that it is not at all clear that the presence of a particle in one 'channel' of a WF serves as an effective reason for collapse of the WF.

    • Jack Sarfatti Michael Towler wrote about my theory: "Living matter and back-action
      In certain dark corners of the internet, can find speculation of the following nature:
      • Propose the wave function/pilot wave is intrinsically ‘mental’ and capable of qualia.
      • Equate
      the pilot wave with the mental aspect of the universe, generally: the
      particles are ‘matter’, and ‘mind’ the pilot wave.
      OK, who cares, except..
      • ‘Mental’ aspect of universe upgradeable to life/consciousness by self-organization.
      Happens when a physical system uses its own nonlocality in its organization.
      • In this case a feedback loop is created, as follows: system configures itself so as to
      set up its own pilot wave, which in turn directly affects its physical configuration,
      which then affects its non-local pilot wave, which affects the configuration etc..
      • Normally in QM this ‘back-action’ is not taken into account. The wave guides
      the particles but back-action of particle onto wave not systematically calculated.
      Of course, the back-action is physically real since particle movement determines
      initial conditions for next round of calculation. But there is no systematic way to
      characterize such feedback. One reason this works in practice is that for systems
      that are not self-organizing the back-action may not exert any systematic effect.
      Well, it’s not obviously wrong..!
      [see p.346, Bohm and Hiley’s Undivided Universe).]
    • Jack Sarfatti Towler continued: "Two-way traffic
      Important to note that pilot-wave theory does not take into account any effect of
      individual particle on its own quantum field (though Bohm and Hiley briefly sketch
      some ideas about how this might happen, see e.g. Und
      ivided Universe pp. 345-346).
      • Idea that particles collectively affect quantum field of a single particle is contained in the standard
      notion that shape of quantum field of a particle is determined by shape of environment (which
      consists of many particles, and is part of the boundary conditions put into the Schr¨odinger equation
      before solving it, even in conventional QM).
      • Celebrity nutjob Jack Sarfatti (see e.g., er.. www.stardrive.org) in particular has emphasized
      the need for an explanation of how the individual particle influences its own field and has proposed
      mechanisms for such ‘back-action’, also emphasizing its importance in understanding the mindmatter
      relationship and how consciousness arises (see earlier slide).
      • Assuming that notion of such an influence of the particle on its field can be coherently developed,
      we can then have two-way traffic between the mental and the physical levels without reducing one
      to the other. Role of Bohm’s model of the quantum system then would be that it provides a kind of
      prototype that defines a more general class of systems in which a field of information is connected
      with a material body by a two-way relationship.
      • Quantum theory is currently our most fundamental theory of matter and Bohm suggests that, when
      ontologically interpreted, it reveals a proto-mental aspect of matter. This is the quantum field,
      described mathematically by the wave function, which is governed by the Schr¨odinger equation.
      Bohm’s suggestion is known as panprotopsychism.. so at least you learned a new word today..!"

      Topical: The theme for this Essay Contest is: "It from Bit or Bit from It?"
      The past century in fundamental physics has shown a steady progression away from thinking about physics, at its deepest level, as a description of material objects and their interactions, and towards physics as a description of the evolution of information about and in the physical world. Moreover, recent years have shown an explosion of interest at the nexus of physics and information, driven by the "information age" in which we live, and more importantly by developments in quantum information theory and computer science.

      We must ask the question, though, is information truly fundamental or not?
      Can we realize John Wheeler’s dream,

      or is it unattainable?

      We ask: ”It From Bit or Bit From It?”

      False dichotomy. It's both forming a creative self-organizing "self-excited circuit" of conscious intent.

      What is its relation to “Reality”?

      Depends what you mean by the word. If one means the totality of possible measurement patterns, then if one believes that the world is a quantum bit hologram image simulation, then matter is the hologram image projected both ways in time from our observer-dependent past particle and future de Sitter dark energy cosmological horizons inside the light speed limited "causal diamond" of our subjective observable universe.

      The hardware hologram screens are the horizons where g00 = 0 in the static LNIF representation of the cosmological metric.

      For example, for static LNIF observers with proper accelerations

      g(r) ~ c^2g00^-1/2dg00/dr

      g00 ~ 1 - r^2/A

      where WE are always at r = 0

      How does nature (the universe and the things therein) “store” and “process” information?
      How does understanding information help us understand physics, and vice-versa?

      Additionally, to be consonant with FQXi's scope and goals, essays should be primarily concerned with physics (mainly quantum physics, high energy 'fundamental' physics, and gravity), cosmology (mainly of the early universe), or closely related fields (such as astrophysics, astrobiology, biophysics, mathematics, complexity and emergence, and philosophy of physics), insofar as they bear directly on questions in physics or cosmology.
