    Thanks to Google Making and Science for helping me pursue my #sciencegoals. If you want to try this experiment, instructions are here:

    The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time.

    Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion.

    Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness.

    So how would one explain that the particles stop forming an interference pattern when it is known through which slit they went through with the pilot wave theory?

    My problem with the copenhagen interpretation has always been that it appears to make
    interactions that are are ultimately seen by a human as special. There are many incidental "fields" that cover a double slit experimental apparatus, and the electrons / photons / whatever don't seem to care about all the other interactions they must surely have over the course of their macroscopic journey. Surely the mere act of having your path, ever so slightly, bent by gravity should cause the electrons wave function to collapse in the copenhagen interpretation?

    Almost but the model is a little misleading. Is no separation between sphere droplets and vibrating substrate because we have 3D quantum particles in 3D space. This means that the sphere droplets vibrate 3D by spinning, shrinking and growing with great speed as a result of its internal luminiferous aether movements and interactions not as result of an external mecanical wake like cause.

    This is a great illustration of an approach I have taken in attempting to deeply understand the double slit experiment. The idea is that the motion of the particle and its position in space is larger than the tolerances of the experiment, in this case, the wave motion outside of the droplet is greater than the difference between the two slits. It explains why the distribution of outcomes seems to be directly related to the two slits even if the "particle" passes through one slit only and also why the observer can affect the outcome because if an observer is near one of the two slits they become part of the experiment. It seems to me to be the application of okams razor to say the phenonium of the two slit experiment is due to an extended yet unseen field around the particle that is affected by both slits than it is to describe it as a superposition. I think that a particle will also appear to behave differently in a vacuum, a gas or in a liquid or solid because this "external" wave will be affected differently. When striking the plate at the back this external and wave-particle "collapses" to what appears to be a point perhaps because the particle is now in the presence of many more particles in the same volume the solid screen. We eject a particle towards the two slits and measure it at a point on the destination screen and ignore the real nature of the wave/particle in transit.

    There is no such thing as physical distance. What physicist confuse with distance is really just the relationship of time and energy. Take the inverse square law of energy, the closer you seem to get to something is really just a logarithmic increase of force relative between two fields over a period of time. The clap you hear when your hands seem to 'come together'* is purely based on the sensitivity and bandwidth of your ears from what is being radiated as the the two field's inertia increases to a critical frequency and amplitude.

    I know... "come together"?, how is this possible if there is no such thing as distance? Well the simple answer is that the universe must be infinitely small. What is perceived as distance is purely psychological, as our brains must reinterpret sensor information that's being received through transducers that we call our senses. Then this information is changed to something that we can actually use. This is exactly how all your electronic devices work also. Nothing new under the sun here.

    This can also reveal the inherent issues in understanding the Big Bang Theory. The Big Bang happened every time a sentient being has been given the ability to realize (sense) the universe around them. Where this infinitely small Universe literally explodes in size as our senses reinterpret the information through our psychological being. If you really think about this, you'll find out what a dirty little joke the name "Big Bang" is.

    If this is still confusing, ask yourself two questions: What size would the Universe be if you were born without any senses at all? What is the size of what makes Gravity or a Magnetic field?

    But I live in a physical Universe and how do my Eyes see distance? Your eyes, like all the sensors, have a bandwidth and sensitivity. Therefore, they are also filters. So when you see a wall, your eyes are actually filtering out everything between you and the wall that is outside of the bandwidth of your sight, and this is what we call distance.

    Important Questions!! Someone with knowledge answer please!!: So for single slit there is an interference pattern even if individual particles are launched one at time. So if you had multiple wavelength particles, is it true that there would be an interference pattern from the multiple wavelengths in addition interference pattern from the single wave length particles? When you have multiple wavelengths, let's say two for argument sake, will superposition take place resulting in different wavelength particles being detected other than the original two wavelengths? If the wavelengths change, then if the particles are shot one at a time, do the detected particles transmute their wavelengths and not just their probability positions of detections? So for the wavelength transmutation question, in superposition of wavelengths, is superposition changing the probabilities of particle position detection or the wavelengths of the source particles also changing at detection?

    so how does pilot-wave theory explain that the patterns one observes in the double slit experiment depend on whether or not one measures through which slit the particle went? would a measurement then "destroy" the pilot wave, leaving the particle flying on a straight trajectory, which would lead to two separate detection regions instead of an interference pattern?

    Are both the mechanics of the oil droplet on the wave and the phenomena of quantum mechanics both reducible to the same equation? Or rather: are all quantum mechanical phenomena replicable by this oil droplet experiment? Or stated otherwise: Is the oil droplet experiment a fitting representation of Bohmian Mechanics? Please, I need an answer because I always thought the quantum force in Bohmian Mechanics as being quite "obscure" - a weird, unintuitive force just to coincide with the Copenhagen Interpretation. But in case Bohemian Mechanics is totally replicable with this experiment it (Bohemian Mechanics) would seem to me more natural, so to speak.

    Pilot wave theory + Gravity: It seems to me that pilot wave theory should be easy to combine with gravity (relatively, physics is hard). You just have to think about gravity a little differently. Instead of working directly on the particle to attract it, gravity (mass) repels the particle’s pilot wave, pushing the wave out from under the particle and causing the particle to bounce toward the gravity source. I imagine the pilot waves would tend to move similarly to gas, in that gas moves from high-pressure areas to areas of lower pressure, and so the pilot waves would move from areas of high mass density to areas of lower mass density. If this is how gravity works, it will definitely behave differently than Einstein predicts at extreme levels, like repelling particles or even exerting no force at all at certain levels. It could explain why matter at the edges of galaxies seem to move too fast, and could also help explain why the universe seems to be expanding. Unfortunately, I don’t have the math expertise to even start developing the equations, but it seems like a plausible idea, and it might be worth looking into for someone much stronger with the Phorce than I.

    This is much more satisfactory for the lay science fan! The copenhagen sounds like sci fi, it offends my common sense - this I have no trouble understanding instantly. I am a great believer in personal perception of things i can see myself. I shall adopt this model until I reason to change. I don't believe the universe is determined though, as a determined universe cannot exist. In my humble opinion the basic fuel of all existence is uncertainty. Time is really a measure of uncertainty, there are many possible futures, as they approach the present, these possibilities begin to collapse into each other and the energy they releases is enough to power full reality, but only for a tiny amount of time. This is all that is needed though, because in the instant of the present, uncertainty is used up and there is no reason why it should continue to exist.
    The universe is like a dragon chasing its own tail and when it catches it time will end.

    Since they both work, and Copenhagen just gives up and says who cares, just do the mat, its which ever math is easier for whatever you're doing.
    Equally same for the pilot wave, since chaotic motion, only way to predict is via the same distribution curves.
    So again, which ever mathematics is most convenient.

    You just blew my mind. I've always had a gut feeling that mainstream quantum theory was misinterpreting the double-slit experiment and not being able to come up with an alternative explanation made me shy away from it as a discipline. You have to suspend belief of a lot of classical physics to make my previous understanding of quantum physics work which should be a red flag in my opinion. It seemed like mathematicians playing at physicists. The pilot wave theory makes total sense to me and seems at least as viable a theory as the mainstream theory if not more. Which doesn't mean anything, but makes me feel like less of an idiot when it comes to quantum theory. I hope the community is designing experiments to compete the two theories!

    How does the pilot wave interpretation account for observer interaction, so when it is being observed why does the pilot wave behave differently to when it is not being observed? Also how does the pilot wave interpretation account for the delayed quantum eraser experiment? Does it mean that if the pilot wave interpretation is right, that it could be possible to clone something exactly? I understand that the reason things cant be perfectly cloned is because you cannot clone the superposition.

    • eddiegaltek
      eddiegaltek 21 день назад

      The particle and the wave are interacting with each other. When you observe the particle you change its position and momentum in relation to the pilot wave. So after observing it (the particle) it will head off in a slightly different and|or with a slightly different momentum.

    • Lawrence Worrell
      Lawrence Worrell 22 дня назад

      This is what I am sort of trying to figure out or asking about with the pilot wave interpretation, such that if you observe the particle, it doesn't seem to necessarily follow that you observe the pilot wave/s.  So what is it that affects the wave when you see the particle, and what is it that makes the wave realise it is being observed and then acts in accordance with "behaving itself" i.e. no interference pattern.

    The only way the pilot wave can go faster then light would be if it's wave function (probability wave? light cone? ) is everywhere in the universe at one, its the size of the universe to begin with, just as a quark has a finite size, it doesn't take time to grow to that size at the speed of light it's just that size. Now to figure out a way to look at particle waves at a distance and take some sort of reaction to it at point in space time outside its light cone.

    If you were able to theoretically build a computer that knows the position of every particle (and its corresponding momentum) that interacts with earth and earth itself, would it be possible to accurately predict the movements (using the computer) of the particles and their future position relative to each other. Because you are predicting the future position of the particles, would this mean that theoretically you could predict the future position of a larger scale object and therefore predict the future...?

    The only problem with the pilot wave theory from what I understand; is the fact if you try and see what slit the particle goes through before hand. You will get two distinct patterns instead of many.

    You haven't mentioned the objections to Bohmian mechanics: it introduces non-locality.

    Interestingly, although Einstein is famous for his "God does not throw dice" objections to the non-determinism of the Copenhagen interpretation, he was far more bothered by non-locality.

    One reason non-local hidden variable theories haven't gotten much attention is because von Neumann published a false proof claiming to show that hidden variable theories are impossible. This argument was simply false, and shown to be false by Grete Hermann. But Hermann's refutation of von Neumann was largely ignored, and so hidden variable theories were ignored despite de Broglie-Bohm being perfectly consistent, only introducing limited non-locality while maintaining realism and determinism.

    Another reason is ESSW, which again has been massively influential despite being 1. completely misunderstanding Bohmian mechanics and 2. completely refuted by experimental observation that confirms the predictions of Bohmian mechanics.
