Dear Vladimir,

Thank you for your kind comments. There are some points which I probably should have made clearer. For instance, when I speak about delayed initial conditions and global consistency, I don't need to advocate MWI, although I don't reject it either. About Wheeler's delayed-choice beam-splitter experiment, I happen to know that it was confirmed by experiments. I agree that photons are waves: in QM they are, in the first place, solutions to Schrodinger's equation. When you measure positions, they become for an instant very localized, but still they are waves. I hope this eliminates some confusions. I didn't have the chance to read your essay yet.

Best wishes,

Cristi

Dear Cristi

If I along with many debunkers of QM weirdness are right, Wheeler's delayed choice test being confirmed by experiment does not mean much. Here is a quick-and dirty explanation of how I see the scenario:

Forget point photons, wave collapse and all that. Einstein's 'photon' concept is the font of all the QM weirdness he himself railed against! Compton himself gave a wave explanation for his effect as Reiter explained on unquantum.net - all proving Planck's loading theory in which an atom releases light suddenly but absorbs it slowly until a threshold is reached and the (hv) quantum released.

In other words the light wave passes simultaneously through both slits and creates the wave interference pattern beyond them. In the famous faint-light case when the pattern emerges dot by dot on the long-exposed film the timing of the dot flashes in the film is an artifact of the sensing atoms individually and randomly reaching their energy threshold and has nothing to do with how the light went through the slits!

When the film is removed and two telescopes watch the slits no simultaneous sensing is recorded because of the energies involved. Reiter has shown how a single gamma ray is simultaneously recorded in two detectors.

I have touched on these issues in my 'Fix Physics' paper, and the scenario above plays out nicely in the universal node lattice of my Beautiful Universe theory.

These papers can be read on my website . I am now trying to simulate my theory to show how things like matter formation, gravity, quantum probability etc. all emerge locally linearly and causally. Big job small capability!

Best wishes

Vladimir

    This explanation might be correct, but the danger is that there is then an argument over alternatives.

    Whereas in fact:

    -QM is an invalid theory because its base presumptions are contrary to the way in which physical existence must occur

    -there is no way in which any form of experimentation can identify the 'bottom line', the degree of alteration and duration involved is too vanishingly small of itself, let alone that, in terms of observation, we receive a representation of it. So the effect known as light would have to be capable of capturing and transmitting accurately and comprehensively exactly what occurred. We are kidding ourselves. Not that there is any problem with experimenting, but we must understand what is possible and then interpret the results accordingly.

    Dear Vladimir,

    Good luck then with this. One should never stop challenging the accepted science. I expect that at this time it is early for this simpler theory you develop to make predictions like EPR. But, there are simpler and more direct tests. For example, if atoms don't absorb photons in quantized units, then we expect that they will also emit photons in a continuous spectrum. But as we know, the atomic spectra are not continuous.

    Best wishes,

    Cristi

    Your point about emission in quanta need not cotradict the loading theory. After all it was Planck himself who proposed it and fought Einstein's point photon concept all the way!

    Obviously I am not an expert on this but I really think it is worth studying the material Reiter has collected because it will clear a lot of questions and open new lines of thought.

    Cristi: your argument that from the Zero Axiom and the principle of logical consistency is puzzling in puzzling. The Zero Axiom is just the axiom that there. Is at least one contradictory proposition, namely itself. But of course there isn't one such proposition, there are infinitely many. There are round squares is another self-contradictory proposition. There is a tortoise that is not a tortoise is another. I could go on. So the Zero Axiom is really a triviality. All you need to say is that there exist contradictions.

    This brings me to a more fundamental problem: which is how you try to use the Zero Axiom and principle of logical consistency to argue for a mother of all possible worlds. Although you *say* that any proposition can be derived from a contradiction, and thus that the *existence* of an entire mother of all worlds can be derived from it, this peculiar feature of the law of logical consistence is only an implication of classical logic: one that has long struck many logicians as absolutely unjustifiable -- which is why there is such a thing as Intuitionistic logic which does *not* permit the derivation of any proposition from a contradiction. Thus, if Intuitionistic logic is correct, your argument fails. It's fine if you want to say, "Well, I'm only interested in classical logic", but unfortunately that's not an argument. It just assumes that classical logic is correct, despite its having a bizarre implication that Intuitionists reasonably deny. Unless you can give an argument for classical over Intuitionistic logic, it's not clear why anyone should accept your argument.

      Hi Cristinel,

      Looking at Wheeler's delayed choice experiment, do you get the sense that there are real wave-functions that are being created (by opening the slit) and collapsed (by closing the slit), such that the waves-functions appear/vanish faster than the speed of light? In other words, wave-functions are the mathematical "bit", but they also exist as the "it", and are not restricted by the speed of light.

      • [deleted]

      Has anyone thought of toggling between particle and wave (particle-wave duality) using the Wheeler delayed choice experiment for use in FTL signalling? In other words, opening/closing the second slit creates/destroys the second wave-function. The second wave-function is what is interfering with the first wave-function and causing the interference pattern.

      Creating/destroying wave-functions can be done to transmit, not information, but patterns, faster than light. On the receivng end, you need a way to determine (a) is it a particle pattern = 1 or (b) is it a wave-pattern = 0.

      There is no reason why you can't place the photon detector a distance of several light hours away. Then, you open and close the second slit to transmit a digital code: 1010 0110...

      If delayed choice is true, then the wave-particle-wave-particle pattern should be transmitted instantaneously (faster than light).

      Anyone?

        • [deleted]

        Cristinel or anyone! Doesn't Wheeler's Delyed Choice suggest that you can toggle on/off an interfering wave (like a light switch); only you're turning of/off/toggling a wave-function that can produce an wave/particle pattern as an observable, even after the photons have passed the slits. That's why it's called "delayed choice". It implies that you can produce an observable faster than the speed of light.

        Marcus,

        What I said about Zero Axiom is not part of classical logic, because classical logic doesn't admit contradiction. The principle of logical consistency may be part of classical logic, but contradiction can't. Why the only alternatives considered should be the ones known at that time? In fact, paraconsistent logics are more suited to admit contradiction and avoid the principle of explosion, so why referring to intuitionistic logic and not to paraconsistent logics?

        "If intuitionistic logic is more defensible than classical logic (as I and many other people think it is), your argument fails." Even if classical logic is less defensible than intuitionistic one, for an argument to fail, it has to be proven false, it is not enough to be less defensible. For example, it is more defensible, from many known examples, that the Goldbach conjecture is true, but this doesn't count as a proof, and doesn't exclude the possibility to be false.

        Best regards,

        Cristi

        Hi Jason,

        If we think that the waves were there, and then our last moment choice affected them, it seems like they change instantaneously. But one can't prove that they were there, and they changed as a result of our last minute choice of what to observe. If we try to measure them to see where they are, and we find them there, the interference is destroyed, no matter what we do later. In other words, once we find them in a place, we can't make them rearrange by choosing to observe interference in the last moment. So we can't use this to transmit FTL signals. Like in the case of entanglement (they are faces of the same phenomenon), it is not known a way to send faster than light signals using this.

        Best regards,

        Ovidiu

        Marcus,

        While from Axiom Zero we can obtain the possible worlds by using the principle of logic consistency, Axiom Zero itself stays outside of these universes. So, the internal logic of the universe may very well be intuitionistic. There are two different levels, which should not be confounded, that of the chaos caused by Axiom Zero, and that of the internal logic of each universe.

        Best regards,

        Cristi

        The underlying point here is about context. We can only consider existence as manifest to us. Nothing more, because we cannot know more. There is always the possibility of alternatives, if A there is always the possibility of not-A, but these are irrelevant for science. Always watch for an argument which presumes these alternatives.

        Hi Cristinel,

        I'm trying to follow you. I could take a laser and shine it on two slits, and the light waves emerging from the slits will produce interference patters. But if I cover one slit, then the interference pattern disappears. I can do this experiment one photon at a time. In principle, I could open and close the second slit in some binary code fashion such that someone at the back of the wall could look at the pattern of (interference pattern),(particle pattern) and know that I'm trying to send a message SOS (for example).

        Now I'm trying to understand how the Wheeler delayed choice experiment works. I still think there is a wave-function involved in the geometry somehow. Sorry, I gotta go. I'm just trying to understand how this works.

        "and then our last moment choice affected them"

        Leaving aside what was there, just assume something for the sake of this point. How does observation/measurement/whatever affect that physical circumstance? It must have already occurred, otherwise you cannot observe, etc, it. Apart from the fact that you do not observe the something anyway, you receive a photon based representation of it, eg light (which is not affected either), and the process of subsequent processing of what is received is not a physical process , as it involves the conversion of physical input to a perception of that, not a physical output.

        Hi Jason,

        Sorry for being too brief, I am attending a conference which gives me no time for other activities. I hope I will be able to give a more detailed answer in a few days. Earlier in this thread, Eckard gave the link to a more pedagogical explanation of the delayed choice experiment, maybe it can help you. The only way I could make sense of quantum experiments of this kind, is by considering that the wavefunction is real indeed, but in a way which depends on the experimental setup. Delayed choice experiments delay the experimental setup as much as possible in the future, and this makes the wavefunction to behave as if it anticipates the future. There is an experiment, you can read about it in Proposal for a quantum delayed-choice experiment, in which the choice is delayed an arbitrary time after the results of the experiments were already collected. This makes even less sense if we ignore QM, but it is predicted by QM. It has been tested by 5 independent teams, in different implementations.

        Best regards,

        Cristi

        Hi Crist,

        While reading the article, the particle-wave duality reminded me of something I learned in biology. Predators (unlike prey) have two eyes facing forward to give a sense of depth perception. As it pertains to quantum waves, the idea is that one "eye" looks at the real part, the other "eye" looks at the imaginary part, and as we all know, the phase = arctan (real/imaginary). I'm not sure if that analogy is accurate or not. I guess the "brain" would be the observer, the scientist trying to figure out what the two eyes (real & imaginary) are saying.

        Stefan,

        I am sorry, I didn't deal with the matter. My intention was to hopefully clarify whether Wheelers mysterious claims can be explained at all without the rather disappointing result that they are based on mistakes or at best on beliefs.

        I was tempted to blame Wheeler for phantasmagoria unless he was not well known for his earlier contributions to nuclear fission and atomic bombs. Of course, the strange theories he got then famous for go back to earlier speculative work e.g. by Parmenides, Einstein, Schwarzschild, Bohr, Rosen, and others.
