    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.

    I definitely prefer the pilot waves, but, unfortunately, quantum mechanics are probably far more illogical than that so I'm gonna stick to Copenhagen.
    Still, pilot waves would make sense thanks to the quantum "aether" of force fields. Particles are nothing more than excitations in the force fields of the universe after all.

    If the particle is creating a wave as it moves and then interacts with it when going through two slits to create the interference pattern, why wouldn't the particle do that when going through just one slit?

    What about the Bell's theorem, though? At some point you actually say that if the De Broglie's theory is correct, then you don't know where the particle is only due to your ignorance. But, to my knowledge, this is really impossible if we accept the observations in quantum mechanics, and the Bell's theorem clearly proves it starting from first principles and taking as hypotesis the QM observations. In fact, if there is a wave that carries the particles through space and if we make the assumption that both the wave evolution and the wave-particle interaction are deterministic, then we could in principle reproduce two identycal results starting from the same initial conditions. But QM as we know it does not predict this!

En donde la materia visible no es mas que materia oscura que se ha desprendido de esta ultima y se desplaza sobre esta en función de la vibración de esta. Materia fluctuando entre oscura y visible. ¿Eso no es lo mismo que dice el Hinduismo y el Budismo de la naturaleza de la realidad?.

    i want to share something with you people, and I'm NOT fooling around here, okay , im very serious about this ;.. it's maybe important for scientists to know ... i studied 1 year physics and then stopped ... was too difficult for me .. so I never studied quantum mechanics etc (because that's in the 2nd year) ... one night I woke up crying ... 'im 99,99% sure i had a spiritual experience ..; Einstein was in my 'dream' ... it was much more intense than just a dream, ... i truly believe it was something spiritual ... because I woke up crying ... with my hands like searching for him but he was gone ... in this spiritual meeting ... we were sitting next to each other and Einstein was showing me a book ... at the time i was very busy with double slit experiment, all the time thinking how is this possible ... it was like an obsession back then ... so we were sitting next to each other with that book ..; I SWEAR to death I have never heard of this name before ... Einstein showed me the name .... D brogle ... later I was looking for this name ... and he probably meant " de Broglie " .... so in my opinion you scientists need to check de Broglie and what he said and truly understand him and this is the answer for the double slit or maybe other till now unexplainable things ...

    I'm not sure if I like the "pilot wave" concept (what I like or not is of no consequence). But I've never been comfortable with Copenhaguen's interpretation about the so called "reality" (what can be equally pointless, at the end of the day).

    • mike4ty4
      mike4ty4 25 дней назад

      Agreed. Copenhagen really is a non-starter for a number of reasons. For one, it simply gives up on the idea of trying to assign any reality at all to the universe when we're not looking at it or not armed with measuring devices; which doesn't make sense because the universe existed long before we did to look at it, and had to exist before in order to be able to form us in the first place, thereby ignoring all the other sciences like biology, geology, astronomy, etc. which all combine together to point to a vastly older universe of which humans are only a tiny part. Though actually that's not quite right - technically it doesn't say a human has to be looking but it _does_ say that a "classical" measuring system has to be in place, yet as far as we can tell all these "classical" objects are made up of quantum particles just the same as everything else, and it gives no definition as to where the border between "classical" and "quantum" lies, and the more and more experiments are done pushing the bounds of superpositions and other "quintessentially quantum" effects up to larger and larger scales, the harder and harder it becomes to think there must be a sharp boundary at all unless you want to imagine the universe puts it at an utterly and completely arbitrary point. That's not impossible of course but it seems to defy everything else we know about how it's built and that's that magic walls don't just pop up in the middle of otherwise smooth spaces. (Or if there is, then what if it ends up being in some place that we didn't think? Why don't we see "quantum" effects occurring in "surprise" locations? Why does the "time of collapse" just so happen to so neatly fit with everything and anything we do that we call a measurement? What general principle governs it, and what would happen if it turns out there's some exception? Where would we even begin to look for one given there's no theory as to why this should be the case?) It rather makes more sense to say the universe is through-and-through quantum, and the classical is an apparent large-scale limit and thus the measuring devices should be in _principle_ - even if not in _practice_ - describable by the same quantum rules. Bohmian mechanics provides one - but as far as we can tell, not provable - way to assign a "reality" before the measurement and thus a way to make it universally applicable as it should be. Even if it's not the right one, that is beside the point - the point is it shows it's possible, and thus the Copenhagen non-interpretation cannot just be assumed to be necessary or gospel truth. And what's forgotten by Bohm opponents is that Bohm himself thought just as much - he did not intend for his theory to be the final word on the matter, only a proof-of-concept to show you could indeed achieve the job and that the "no go theorems" had loopholes that could be gotten around. So even if it's not the best or not complete enough doesn't mean the _Bohmian program_ , as it should be called, is pointless or crap.

    Hi, i actually see this completly resembling the wave-particle theory. Now what i get from this is, "Quantum General Relativity".
    Electron is a particle that jumps ina spacetime fabric that creates ripples producing wave interference.
    Hence both particle and wave phenomenon is satisfied.

  • An artist theory on the physics of 'Time' as a physical process. Quantum Atom Theory

    Could the great similarity between fluid dynamics and quantum mechanics be because everything is based on the same universal process? This idea is based on: (E=ˠM˳C²)∞ with energy ∆E equals mass ∆M linked to the Lorentz contraction ˠ of space and time. The Lorentz contraction ˠ represents the time dilation of Einstein’s Theory of Relativity. We have energy ∆E slowing the rate that time ∆t flows as a universal process of energy exchange or continuous creation. Mass will increase relative to this process with gravity being a secondary force to the electromagnetic force. The c² represents the speed of light c radiating out in a sphere 4π of EMR from its radius forming a square c² of probability. We have to square the probability of the wave-function Ψ because the area of the sphere is equal to the square of the radius of the sphere multiplied by 4π. This simple geometrical process forms the probability and uncertainty of everyday life and at the smallest scale of the process is represented mathematically by Heisenberg’s Uncertainty Principle ∆×∆pᵪ≥h/4π. In such a theory we have an emergent future unfolding photon by photon with the movement of charge and flow of EM fields. This gives us a geometrical reason for positive and negative charge with a concaved inner surface for negative charge and a convexed outer surface for positive charge. The brackets in the equation (E=ˠM˳C²)∞ represent a dynamic boundary condition of an individual reference frame with an Arrow of Time or time line for each frame of reference. The infinity ∞ symbol represents an infinite number of dynamic interactive reference frames that are continuously coming in and out of existence.

    The problem is: the pilot-wave must to collapse at moment to observation, because the particle is measurment but the previous wave must to disappear; instead both (pilot wave and its particle) are still existing.
    This pilot wave and particle existing simultaneously contradicts the principle of complementarity.

    Wouldn't it be great if we allowed even more than two competing theories for ALL fields of science (instead of subtle totalitarian "standard theory"s). And wouldn't it be great if ALL scientists had no emotional investment in any theory, but could dispassionately investigate them all without any subjective "likes" and "dislikes" (prejudices).

  • forestsoceansmusic

    "Does this mean that this is what quantum particles are actually doing? No." Instead of "mean" you should have used the word "prove". This doesn't prove the case, but it is a good theory/model for explaining the observed results of quantum experiments. Certainly this is a better 'Occam's Razor' model, not needing: "spooky action at a distance", "superposition", and "parallel universes".

    "If there's any uncertainty it's just due to our ignorance of what's actually going on." I've always thought that.

    I figured it out. WOW how simple. Memorize 100 "physics phrases" of five words each into sentences, and then combine five of them them randomly into paragraphs. Again, combine five of them into a paper. Combine five papers and you have a thesis. Combine five theseses (sprinkeled with homework, papers, a mid-term and final) and you have a course. Combine five courses per year for five years and earn a masters. Add five more semesters and a 200 page book and you have earned a PhD. Welcome abord Doctor. Then, regurgitate the above to students and ask them if they are too stupid to get it. Those that say they got it become teacher's assistants.

For photons themselves time does stand completely still always and because of that a photon experiencing traveleling instantly to anywhere in the universe (if the theory is correct).

    the pilot wave theory suggests that there are speeds faster than light

    • mike4ty4
      mike4ty4 Месяц назад

      Yes, in a sense. However, the faster than light speeds are not believed to be observable, because we still cannot _predict_ the particle's position to more than the probability |psi|^2 as in standard QM. It _has_ a definite position before we make the measurement, but all we can _know_ is the probabilities from the wave function psi. (This is the main difference with standard QM. Standard QM says it _does not have_ a definite position before the measurement, only an ill-defined one determined up to the probability distribution.) On the other hand, there is some suggestions that in BQM it may be possible for an "off-equilibrium" distribution to exist in which case that one could potentially observe this (in particular the |psi|^2 law breaks down and one can measure more precisely than the Heisenberg uncertainty principle's limit - perhaps, this is what the "Heisenberg Compensators" do in Star Trek :) Star Trek's universe is a BQM universe as there's some way to make off-equilibrium distributions possible and that is used in the transporter :) Too bad the writers didn't seem to know about this, it would make a rather compelling speculative justification for that technology AND would be consistent with Star Trek's universe as one where FTL is possible.), and also refute BQM if it doesn't happen, but there is as of yet, I believe, no known way to attempt to induce such a distribution: it appears to be rather similar to the second law of thermodynamics, in particular that law can in theory break down but it requires extremely unlikely (as in "odds that make winning the lottery look a googol times more common than breathing") events to occur to see a violation. Thus unless there is some radical breakthrough on either the theoretical or experimental front, no observation of faster-than-light action by BQM, if it exists or not, will be possible.

      So basically if i say that pixies are splitting up the quantum in the 1th dimension and carry each halve through each split to then put it back together and let it go it's merry way, you CAN NOT tell me that's wrong? ... funny ^^
      Well i gave my preference, because the other seems 'further out', basically 'if two theories compete the simpler and more obvious theorie feels like it could be closer to the truth than one that's more complicated and less obvious.' ... know it's not real science, but if you give it some thought, it makes more sense than picking the more complicated one. (and yes, that is in support of my pixie theorie ;) given you want to argue that my pixie theorie can not be true for that reason, but the theories proposed here are equal).
      ps. I am an amateur physicist, or simply somebody interested in all sorts of sciences and knowledge :) ... personally i feel that our understanding of QM could be increased if we adopt another way to look at how we construct the dimensions. I watched the youtube series 'the Xth dimensions explained' a coupe of years back and though about this for quite some time and though about how it might be wrong. And came up with a different setup... The 0th dimension is the time dimension, it's a vector that points forward in all directions, seeing there are no space dimensions in this dimension, it can ;) and it's how we assume time works, it goes forward everywhere regardless how you move or in which direction. Then at a 90 degree angle there is a vector that designates a point, either a point in time, or time through a point. Then adding another vector at this point at 90degree we can designate (the direction of) a line in the 2nd dimension, add another vector at 90degrees we get a field, add another vector we get a 'cube' (though it's more like a 3sided pyramidal cone) ... and strangely enough we can do so with each dimension still having all degrees of motion free and undefined, so you can go further up. But anyways, for quantum mechanic you only have to work in the 0th and 1th dimension, and if time is equal everywhere, and a point only defined by one vector, then basically where it shows up in 4D space (the traditional 3D world we live in) is irrelevant, we could even find it at 2 different locations, because the time is equal, if time is not equal everywhere the quantum may jump around to exist at it's designated time ... anyways, i only know very few QM effects, basically those that made more popular science, and i have no background in the field and can thus only think about it conceptually, but found it interesting that building up the dimensions in a different way, starting with time in the 0th, then vectors to build up dimension, and understanding degrees of freedom in relation to the objects that could exist in those dimension, gave an interesting logically consistent build that seemed to also sort of explain 'why' (that describe you mention) certain effects/observations might take place ... maybe give it some thoughts in your spare time, as it could also well be the rambling of some amateur wanna be physicist (also recommend watching those videos, mainly the one on the 0th dimension) ;) ... ps. happy new year, and good luck on your endeavors !
      ohw, i would suggest maybe moving into the field of quantum entanglement, if we can get 64 pairs of them working at infinite distance, we can basically build a 64bit interstellar 64bit digital connection. The only tech that Startrek seemed to have never attempted to explain, yet simply used for instant communication across lightyears of distance. Because who in the audience (or at home) wants to 'staytuned' for years to receive an order from the Headquarters. Yeah, i extrapolated that after dutch scientist managed to get an entanglement working on a more spooky distance ^^ ... hey, science without dreams is like butter without the peanut variety. ;) ... w/e you do, follow your passion !

    • mike4ty4

      Except that we CAN'T - that's the problem. Not until there's some significant and radical breakthrough in our understanding - because the different "interpretations" do not make any experimentally testable predictions that are at odds with anything in standard quantum mechanics. They change around the "back end" but do nothing to the "front end", as it were. And because there is no prediction, there is no obvious place to start looking for a way to attempt such a proof. It will require more refinement of existing interpretations and more out-of-the-box thinking, or a real serendipitous discovery, before we will be able to actually bring evidence to bear upon the problem. It is a real, serious and genuine gap in our knowledge of the universe and imo one that too often gets glossed over. Physics should not just be about trying to predict experiments I think, but to _describe_ what is actually "going on out there in the wild". That description may not be known to be absolutely what is going on, but we need one. Right now we have a bunch and all of them look equally good because there's nothing they seem to describe better.
      I know! I'm frustrated by it too but that's how it goes!!! :) Aww. And I'm actually getting a degree in Physics, and might even go on to graduate school to be a real research scientist!
      "SCIENCE PROOF" ... yeah, we all would like one. But sometimes we also have to say where we don't know. That's another aspect of science, to be meek and admit where your evidence doesn't let you go far enough. And yet that's where you then need to exercise your imagination, to try and create possibilities with the hope one can be tested. In a way science itself is like the quantum wave function. Our imagination spreads out with all kinds of fantastic possibilities. Then we find evidence. Which narrows it down to one or a few. Then we find something else we don't know and our imagination now spreads out again, but from this new point and not the old one since those possibilities were discounted. And on and on it goes. (Which is kind of how the Bayesian QM approach works :) )
      The important part about this theory to me though it is at least tells me there is _A_ way to understand QM in such a way it can fit in with the world we experience and not seem to utterly contradict it.

    but the droplet interacts with other matter, the interference pattern formed is by those 'other matter'. when a single electron passes through a double slit and still forms the pattern, there is nothing else (otherwise the experiment itself will be wrong). so if you say that what happens at the quantum level is actually deterministic then the question will remain what formed the pattern? won't this be more paradoxical?

    I wonder if pilot wave theory is the same as quantum mechanics in that that Quantum particles have a "surface tension-ish charge" that if it broken it collapses the wave function. Perhaps the "surface tension" is just made up of charges or interference with the Natural Energy in nothingness like in the "in a nutshell - what is nothing" video. Perhapse observation is s interacting with energy wave holding up the partical ball collapsing it?

    Notice how the smaller droplets interact with the larger ones. Almost like an electron stuck to a nucleus, or atoms coming together forming a molecule. Its only momentary but its fun thinking about it, i guess we like to see patterns that why i look at it that way.

    i think it is PILOT WAVE THEORY which could explain lot of understanding about QUANTUM MECHANICS but it's not the actually same.As each droplet have it's certain a new wave at a time as the times it touches the surface a new wave create but I have little confusion about the waves generate from an electron is it a single wave which redistribute again and again around it in QUANTUM mechanics?

    It's a great mistake to assume that, if the math is similar in two analogous systems, so is the underlying physics. After Bell, do pilot waves really make QM any clearer? You still have to deal with non-locality.

    • mike4ty4
      mike4ty4 Месяц назад

      It's a mistake if you were to _conclude_ that the physics is similar. But when it comes to _making hypotheses_ you have a great deal of freedom to imagine and draw inspiration from many sources. Given that QM's only deterministic dynamical equation is a wave equation, looking at other wave phenomena is a not entirely off-the-wall bet when trying to account for the when-time or the applicability of the non-deterministic dynamical equation of QM. And so far this hypothesis makes the right predictions for everything we are able to experiment with so we don't seem to have made a mistake with it so far. Namely, insofar as it makes a prediction at all it makes the same predictions as ... standard QM. The problem with that, of course, is we _need_ a different prediction to be able to test it, or a prediction in some domain where standard QM does not apply or was not tested, that we can then test. Yet we don't have that (There is some speculation about a "quantum non equilibrium" state as being possible under Bohmian QM where it would predict deviant behavior from standard QM, but there is no known way to extract from the theory some kind of method to force or induce such a state and thus no way to test whether or not such a thing can actually happen or not and so evidence or falsify the theory.).

    At least two major differences between bouncing silicon balls and quantum physics. Observing/measuring does not collapse the wave distribution of the tiny bouncing silicon balls. Interference of quantum particles can happen non locally. Sorry, but even if tiny bouncing silicon balls make more intuitive sense ... its still not quantum physics

    Definitely more plausible than the Copenhagen interpretation.

    • mike4ty4
      mike4ty4 Месяц назад

      Yeah. Well the real problem with Copenhagen imo is it's not well-formulated or well-defined. Actually this is not entirely different: in Copenhagen you also have a classical component. The problem with Copenhagen is that it is undefined as to the _boundary where_ classical mechanics operates and where quantum mechanics operates. (The "wave function collapse" is said to occur when the two come into contact with each other, and measuring devices are considered classical, but given they are definitely known to be made of quantum-mechanical particles it seems odd to imagine that somehow the laws of quantum mechanics are arbitrarily suspended for them at our convenience.) This doesn't really solve the problem. The original measurement problem is where does the _temporal_ boundary between the deterministic many-possibility evolution and indeterministic reduction to a single classical possibility exist. Copenhagen simply exchanges this temporal boundary question for a spatial boundary question and thus solves nothing. It's just a crap salve that makes it _look_ like you're solving stuff. Bohmian is better than that because it says that _at all times there simultaneously exists a classical and quantum state_ for the system under consideration, so this boundary-making problem does not exist at all, it solves it. FWIW my favorite interpretations are Bohmian and Bayesian (epistemic) QM, the least favorite are Copenhagen and Many Worlds, and everything else is somewhere in the middle.

    I like many videos on this channel, and this one has very cool visualization of wave mechanics. But I have to speak against "Pilot Wave Theory" as an alternative to Copenhagen interpretation, which I understand unsettles a lot of people who are interested in physics but haven't studied QM systematically. Einstein was wrong about "god doesn't play dice", as so many experiments have supported QM rather than deterministic theories. If you are interested, EPR paradox and Bell's theorem are good starting points.

    Could the pilot wave be the reason the EM drive works? Wave interaction creating forward momentum?

    • mike4ty4
      mike4ty4 Месяц назад

      I've heard those claims but haven't really looked into the details. My gut would say no because Bohmian pilot-wave QM should not make any predictions different from standard QM. Standard QM doesn't allow for odd thrust, so I don't see why Bohmian QM would do so. Then again modeling the EM drive quantum-mechanically is a problem in Quantum Field Theory (QFT) for the electromagnetic interaction, and there is disagreement as to how to interpret relativistic QFT through a Bohmian framework (e.g. what is the choice of beables? do we go particles first, fields first, or what?).

      Dogmatism, if not in science proper then in science education. The honest truth is that the interpretation problem is unsettled as in - completely, because all interpretations make the same predictions as standard QM. It would be better to first teach that QM from a purely mathematical point of view lets us predict experimental results, but because it contains two dynamical laws with no explicitly defined conditions as to the when-time at which they apply except the _observed_ behavior of one law is known to apply with a measurement, then say there is no proven way to resolve this, and offer a set of _possible_ interpretations. Insisting on one, Copenhagen or otherwise (I assume Copenhagen) = dogmatism because there's no evidence in play and no way known to generate any.
      Yes science SHOULD not have dogmatism but science is alas a practice done by PEOPLE, and PEOPLE have a penchant to be dogmatic. So science as it exists in ideal, and as it exists in real life practice, are two rather different things, and unfortunately the latter often fails to live up to the ideals of the former. You might be interested in another Veritasium video here called "Is Most Published Research Wrong?" to see how deep the rabbit hole on this one goes. FWIW there's a lot of online "kook pots" who are often lay observers whose scientific knowledge is lacking and don't make very decent and informed arguments as to the existence of dogmatism in science, and often propose pet theories with basic misconceptions in them, but on the other hand the scientists' reactions to these theories is to just dismiss them by pushing dogma against them, not just evidence, when in reality the better approach is to point out the misconception but have the humility to also admit that real science yes can indeed fall into dogmatism traps too sometimes and is not a perfect practice so at least they are right imo to be skeptical though I think that's rather unfortunate because a lot of science IS really good and we ignore it at our own peril (see, e.g. Global Warming and Vaccines) but "scientists" need to own up some responsibility for this in how they deal with the public. (And while I'm not a full bones-earned scientist yet I'm getting my degree in the stuff, physics and computer science.) IMO the only "kook pot" to get really angry at is the one who tries to con people out of money in fake medical scams, etc. which lead to people dying or losing a lot on false hopes, and if a lot of people who AREN'T scammers have a perception that science is dogmatic, whether they propose ill-informed theories or not due to their own personal speculation (which I believe is a good thing to do, to question things for yourself), perhaps one should investigate at least the reasons for that perception and that's what I advocate. Part of this is, I believe, scientists' attitudes, and part, poor education, and I say especially poor education. (And if we had better education we'd probably have less "kook pots" because people would be more encouraged to also not get too dogmatic about their OWN private speculations either and seek more knowledge if they want to, which is the common failing. They question something - which is !!!!GOOD!!!! - but don't fully understand what they're questioning, and don't see this, because they haven't learned how to or want fame. Real education would, while not making everyone into a scientific expert, at least get people to understand well the basic process of scientific thinking, and also dispel the notion that most scientists are somehow "famous" people. Really, the great man theory of history has to die hard! :) )

    Assuming the casimir effect is caused by plates being to close for quanta waves to form, you could conduct an experiment to test for quanta outside of their carrier waves, also assuming the we have instruments that can measure quanta and not the just their waves.
