    • I have a theory here: electromagnetism and electric field itself is not quantized, but the effects on particles it is, that's why you can observe single photons interferencing with itself. In reality there are electomagnetic waves emitted but they are too weak to trigger any measuring device. Prove me wrong.

  • It's important to note that "observing" a particle is much more involved than what the word would imply. It's not a passive act, in order to observe a particle you have to hit it with another. In such a sense, every single particle in existence isn't "observed" until it interacts with another, so for nearly the entire life span of a particle it doesn't actually exist, it's simply a solitary wave.

    • Underrated comment. When they stay stuff like this they make people think that literally “looking” at it changes it’s behavior and it’s like… no hitting it with another particle to see if it’s there or not changes it’s behavior, sounds way less mysterious this way tho.

    • Yeah it seems just about every visual explanation of the dual behavior observed in the slit experiment depicts the observer as this passive eyeball or camera, and also uses the word "choose", as if the particle can somehow make a choice between passing through one slit or the other, or both, which is all extremely misleading.

  • This sounds exactly like Heisenberg’s uncertainty principle, in which a particle’s momentum and location in space cannot be determined at the same time, leading it to have multiple positions at once until observed. The same can be said about Schrödinger’s cat. In this thought experiment, a cat is in a black box with some poison. Next to the poison is a radioactive source. When the source reaches a certain count rate, the poison is released; the thing is the decay of the radioactive source is unpredictable, so cat at any point in time is both dead and alive until observed. Another analogy is if a tree falls and no one was there to hear or see it fall, did it really fall? Both theories have been used to question the possibility of a multiverse where every possible outcome generates a new universe. The idea of life being a “computer” program is logical, as almost all aspects of nature have mathematical attributes that are perfectly related to one another. Every possibility follows certain “coded” rules/axioms to carry out. In that case mathematics and physics is just the study of reverse engineering the program of the simulation. But when you reverse engineer a program and come across something that shouldn’t run, like photons arranging themselves when observed, you question whether this is intentional or an undefined natural error. It breaks the algorithm that we have documented for centuries.

And these were people who had never attended school nor knew the English language. And within an hour, they were discussing among themselves the dual wave and particle properties of photons. They were drawing the diagrams in the dirt! Since that day, I've had a deeper respect for the remote, isolated tribal people of the world.

    • Yes, for most interactions, but photons do not directly interact. To observe which way, special crystals that split the photon in two can be used so that if the photon travels through one side, one photon can hit the screen and the other can hit a detector. All of these interactions still impart momentum which affect the outcome. MIT OpenCourseware has a great lecture series on this that actually gets into the math but also explain it clearly.

    • Yes, the detector or measuring device used in the double slit experiment interacts with the photon and alters its behavior, causing it to act like a particle. This is because the act of measurement or observation involves the exchange of energy and information between the photon and the measuring device, which disturbs the photon's wavefunction and collapses it. The type of detector used in the experiment is important. For example, a photon passing through a slit may be absorbed and re-emitted by a detector, which can cause a change in the photon's energy and momentum. This disturbance can alter the photon's path and cause it to behave as a particle, rather than a wave that undergoes interference. Additionally, the act of measurement introduces uncertainty into the system, which can further disturb the photon's behavior. The position of the photon is uncertain until it is measured, and this uncertainty can propagate through the system and disrupt the interference pattern. In summary, the presence of a detector or measuring device in the double slit experiment interferes with the photon by altering its wavefunction and introducing uncertainty into the system. These effects cause the photon to behave like a particle rather than a wave, and the interference pattern disappears.

    • @@DarkSpice84 The wave function of a particle (or more generally a system) contains all the information about the state of that particle. It can be used, for example, to calculate the probability of the particle being in a particular position. Let’s say you want to know which slit a electron went through without interfering with its current state (that is, you want to make a measurement and not change the wave function, so it keeps the cool wave pattern, as if it was not measured). Measuring some quantum state of a particle is basically applying a transformation to its wave function and reading the output, so you can’t directly measure something out of a particle and expect it to behave like you did nothing. So the best approach here would be to copy the wave function, perform a measurement on the copy and the original keeps unchanged. Sadly, we can’t do that (search for no-cloning theorem for further clarification). In short, you have a wave function 𝛙 upon which you can take measurements by applying some transformations to it, but whenever you do so, it changes to another wave function 𝛙’. You may try to clone this wave function, but the best you may get are imperfect copies. I hope this sums it up, cheers.

  • Hi! For a long time I have wondered what exactly we mean by saying "when the photons are observed" and I encountered this video when I tried to look it up. I'm a chemist and have learned from analytical chemistry that we can't measure anything without it interacting with the material of the detector. I was of course curious in how we exactly can "observe" something halfway through an experiment without fundamentally changing the experiment and therefore likely the result. So when I heard that "scientists used a measuring device to observe the slit that each photon passed through" it obviously peaked my interest. From my understanding, and please correct me if I'm wrong or misinterprets the experiment, the so-called measuring device or slit-detector is actually polarizing filters which do not perform any kind of measurement or detection themselves. By only filtrating forth polarized light from each slit (which I think are perpendicular to each other), it would presumably be possible to identify which photons passed through each slit later on. If this is the case, I think it is an extreme stretch of the definition detector or measuring device if no observations, measurements or analysis were performed by this so-called device. I realise that this is likely an extreme simplification made in order to illustrate other points, and while it is false (at least from my interpretation of what a measuring device is), there might be a valid argument that "we might as well view it as a detector for the sake of simplicity". So there is no magical detector. Darn it, another childhood dream squashed. I still have some issues with general statements I've encountered such as "the photons change their behaviour because we observe them", which likely are simplifications of "in an experiment in which we tried to observe the path of the photons, they behaved like particles instead of waves". While I don't think either statements are necessarily false, they both seems a bit misleading if left on their own. From my perspective, the experiment when using the filters is, at least to some degree, fundamentally different from the one without filters. We can observe "that perpendicular polarized light behaves like particles instead of waves when passing through the slits", and don't get me wrong, it is definitely a interesting and wierd result that clearly illustrates the wave-partical duality of photons. However, to draw the conclusion/interpretation that "they behave differently **because** we try to observe their paths" sounds rather backwards to me. While it is true that we set up the experiment in order to determine their path, a less misleading way to express the result could be "they behave differently because we fundamentally changed the experimental conditions, i.e. we removed all photons that didn't exhibit certain properties (i.e. a certain polarization)". While this might be obvious for physicists and chemists alike (that we can't measure anything without interacting with it), I don't think it is as obvious to people with other backgrounds. The slit-detector is often breezed over in explanations of the experiment and is therefore more or less implied to be a passive observer. A reasonable explanation for this is that we can't explain everything in a 6 minute video. We would need to explain what polarized light is and why that is significant. Easily understood explanations are without a doubt important, and can be justified even if they oversimplify things (such as the slit-detector). However, when doing an over-simplification and just saying "we just observe the photons" it would be easy, and I think very reasonable, to add a large shining caveat saying "the detector is not a passive observer and that it by its very nature may influence the outcome of the experiment". While this likely would result in some confusion, it would more importantly raise questions which are the bread-and-butter of curiosity. I genuinely think that Newsthink and physicists in general only have the best intentions in mind, but I find this sort of explanation (without any caveats) unnecessarily misleading nonetheless. While interpretations such as "photons change their behaviours/properties **because** we observe them" are alright to make, I personally find them missing the mark of what the actual experiment was about and what the results really showed (i.e. if I understand things correctly). Is it possible that the photons behaviour changed **because** we tried to observe their path? Yes anything is possible, but I find it rather speculative (to put it mildly) if this is the only data that they base it on. In general, while it is easy to say "You should stay sceptical even when experts explain something" or "Of course the experiment is more complex than it seems, we're talking about physics and the video is 6 minutes long", I don't think that's something we should expect people from outside the scientific community to always take into consideration. And that is why i wrote this post (also because I wanted to know if I've misunderstood something). I would also be very interested for any information regarding other real experiments (i.e. not thought experiments) that deal with "whether photons behave differently if "observed"". Have a nice day!

    • You're correct about the polarizing filters. Each filter blocks out a certain direction of the wave, x y or z. By combining two different polarizing filters you should be able to block out the x and y directions of the wave, for example, leaving only the z direction. It's true that these filters aren't "measuring" or "observing" anything in the more common way that we understand those words, but I think they do "observe" the light in a more quantum/abstract way than we probably understand. I'm a biologist though so definitely not my field of study.

    • @@SpencerfromEarth hi, thanks for your response. It’s good to have confirmation about the filter blocks, so thanks again! After I wrote this comment, I spoke to a physicist friend of mine and thought a bit more about the experiments. Most of my criticism stands about how the concept was described in the video but today I wouldn’t have added the comment about that “I find it very speculative to say that the photons behavior changed because we tried to observe them”. I still find it misleading and very easy to make far-drawn conclusions from it, but I was also a bit too focused on the experiment where many photons were sent in and not the experiment where one photon was sent at a time. There is, as you say, clearly a quantum mechanical phenomenon happening at the filters as shown by the latter experiment. So it’s very likely that it also happened in the first mentioned experiment (where many photons were sent), so it’s not only that polarized light interacts differently than unpolarized light which effected the result. It’s therefore really a question of semantics, and while it could be interesting to delve into a deep philosophical discussion about what “observing” really is, I don’t really think it’s worth it. As I’ve mentioned, I personally don’t like the word *observing* to describe the phenomenon, but I don’t really expect people to care much about my stickler tendencies. Hope you have a nice day!

  • I have a theory that this is what Stanly Kubrick was basing his movie on Space Odyssey 2001. The light sequence at the very end as being observed by the pilot (Boman i think) traveling through space after entering a monolith which looks exactly like a slit. The slit is solid black but after he enters he then observes a light show of colors that couldnt have been seen before. Also , everyone knows how perfect kubrick directed his movie shots are, theres never an error meaning the continuation of the story is never out of sequence, except for 1 time i noticed and this could refer to the delay and observation of a particle correcting itself. The jacket appearing on a chair then disappearing in the next shot was thought to be an error which is unlikely, theres a lost and found alert is being said in the following screenshots, meaning that it corrected itself after the viewers observation. A majority of the movie is presented with black and white backgrounds (duality) for example the ceiling is made of white light in the U.S. Spaceship just as the floor in Bowmans room is lit up in white light. We see this again in the meeting room ,black ceilings and corners with white light walls. The white light is also in the center of the ship thats rotating with Hal. Im suggesting theres an inside world and an outside world that exist simultaneously but not observable , its seperated by the light. The absense of light is the the monolith, solid black darkness and going through it brings you to the other side. Bowman went through it twice. 1st time as a pilot and 2nd time at his death bed where he becomes a star child made of light. I cant explain all of it here but i think you can see where im going with this, im very interested to here what you guys think of this.

  • I’ve seen a lot of people saying it’s the physical interaction of the observing device that interferes with the photon, by “bumping” into the photon and causing it to change. To reiterate, if the device is turned off, the photons return to being waves. So once turned on the observing device must be emitting waves or particles that interferes with the photons and causes it to act like a particle. This makes the most logical sense to me as well. A photon behaving like it “knows” or has “consciousness” seems less likely to me. So my question is, what if we put more than one observing device in the experiment? For example, one device pointed down (eagle view), another pointed to a horizontal view, and one behind the photon machine. All devices turned on. Would this change the outcome of the pattern the photons make? Would different amount of devices and angles yield different results? I’m not sure if this experiment has been done. I’d love to do it myself but I figure it’ll be difficult to get your hands on a photon shooting machine. Thoughts?

As a rough example, imagine there is a bowling ball moving on the bowling path, and you throw another bowling ball that should hit the first bowling ball, bounce from it and go back to you to tell you that there was a moving bowling ball, from which your bowling ball bounced. And of course, after the hit not only your bowling ball bounced, but also the initial ball changed it's course. Something like that could be happening on a level of particles, in my assumption.

Everything being recorded as if in some alternate reality. Well maybe not that basic, it's hard to express in words, but I get the impression that most humans get a feeling at one time or another/ or many times, that you are being watched by something unknown. One time when in Europe I accidentally took a large amount of a unknown psychedelic ( long story ) it keep me up for 4 days and I had thought I went mad. During this time a weird world revealed itself to me, there were these red balls like eyes everywhere constantly watching and monitoring every movements we humans make, you know the red eyes in the matrix sentinels, well I was seeing those things literally everywhere all around us, you moved and it followed your movements like a lens in a camera. There were millions of these things everywhere I looked. I hadn't seen the Matrix film back then as this was in 1993 and the Matrix wasn't released until 1999. You have no idea how terrified I was when I saw the film for the first time and those red eyed sentinels were in the film. Its not a coincidence that most people feel weird when looking into camera and asked questions or told to say something..

So if you are tuned to see particles, you will see particles. It's like looking at clouds with pictures of animals in your head. But the same thing will happen, if you look at the former particles with an idea of probability waves. Both are concepts, that work quite well under certain circumstances. And both will fail under others. Most people think, physics is about finding out how exactly reality looks like. But the first hard lesson is, that you can't. But you can find out, how reality behaves. The models and theories are made to understand that good enough to make smart predictions. And the analogies, like "photons behave like particles" (IF observed in certain conditions!), are made to get familiar with that stuff. Let me mention one last point, if you're still sticking to a it"s one or the other idea. Ask yourself, what a real particle would be like. A solid orb? Made out of what? Which diameter? Homogenious or not? And how the heck would a complex probability function look like in reality? Etherial Numbers floating in space and time with real and imaginary parts? So don't ask, what it is, but how it could be described best to make the maths consistent with the measurements. Sorry to say that, but studying somehow demystifies the whole stuff, and i could have known.

When the consciousness of an observer connects to the consciousness of a particle there is an energetic and magnetic-like reaction.

  • I don't think we live in "simulation", but i do think that universe we live in, works similar to a computer program. it's a FACT that by observing something, you are altering it. or to say it in a different form "you can't observe something without altering it". It's very simple concept, in order to observe something, you must interfere. for example if you are looking at something, then particles interact with your eyes, which is interference. same happens with cameras. if camera sensor is able to see whatever it is looking at, then that object is also able to detect presence of the camera sensor. more fascinating thing for me, is fabric of space. we know it exists, because that's what causes gravity. gravity is 4-dimensional. when on earth (or other planets), if you drop something, it will fall towards the core, but in space, if you place something on fabric of space, it will bend inwards, making a 4-dimensaionl "bowl" and things will fall into it. if you'd be able to get in center of a planet, you'd be in 0g. so if fabric of space exists, then it means that fabric of space MUST have shape and size. what is that shape and size? I think it's a cube, because that would make most logical sense and also refers to the theory that it's all a big "simulation". another interesting thing, is that there MUST be tiniest particles that cannot be destroyed, which act as 1s and 0s, as in binary. if particle exists, it's a 1, if no particle, it's a 0. which means that everything in universe is basically just data, that can be created, copied and/or deleted. another thing about fabric of space, if it exists (which it does), then it must have particles, but what does it consist of? normal matter don't collide with it, is that what scientists call "dark matter"? but yes, i too think that universe is more like a computer than "natural".

  • This has been answered years ago. Pilot wave theory explains why the particles, including electrons , act the way they do until they are "observed." By observed, they mean detected. After all, we cant see electrons, we use visible light photons to see. Electrons are WAY smaller than photons. We cant observe these particles with our vision. When these particles are sent through a detector to "observe" their position, the pilot wave is induced off and the particles can move in a straight path because they are no longer influenced by their own precursor wave. Lots lf lead scientists dont like this explanation because it removes the mystique of particle physics and proves the motion is deterministic. It's a lot less sexy and hard to sell when the mysticism is explained.

    • I am a programmer and I thought about the idea, that the world might be programmed a lot. From this perspective the idea, that light behaves like a function whenever not observed closely seems like a typical optimisation. Why simulate a myriad of photons, when you really only need a macroscopic light/shadow texture. I have many ideas about time, but it is very hard to order them. Time goes slower in proximity to large masses and obviously where there is a large mass there is a lot of matter and where there is a lot of matter a lot is happening and where a lot is happening a lot has to be computed - so it makes sense that the program needs a lot of time to calculate each frame in these regions and therefore time in these regions runs slower. This is obviously not a commonly used programming strategy since in basically all programs time is a global variable and not depending on space or anything else. Time also goes slower when moving very fast and this makes sense since an object that moves very fast potentially experiences a lot of different things in a very short time, which again is computationally expensive. In the end I really can't wrap my head around all this though. It is an intriguing idea at the least and I'd really like to explore these topics deeper and gain a real understanding of it all.

The observer can leave the room but as long as the interaction or detection takes place at those locations you get identical outcomes in general. Similarly, if you move the screen toward the slits the pattern changes from a double slit interference pattern to 2 single slit interference patterns but never to 2 single slit patterns with no interference like when the detector is on the screen side of the double slits. The observer needs the detector to interact with the system and the observer observes the detector.

  • The biggest problem I have with the description of this experiment, is that "observed" is just our way of describing the process. If you just LOOK at the double slit experiment, nothing changes or happens. Instead, you are using a measuring device that sends out a wave of some kind to bounce off of the "flung" electrons, to measure what is happening. Its an over simplification to consider measuring and observing one process. The machine measures. We observe the measurement. Turn the machine off, the measurement goes away, and so does the particle pattern. OUR observation has nothing to do with it. I also picture the experiment in reverse. Its not a case of the measurement affecting the electron. Its a case of the measuring devices putting out a wave that distorts space time. And then the flung electron has to traverse those distortions. When an airplane rises, its because of aerodynamics. The airplane wings move into the air so much that the air starts to push the wings downward and upward. The airplane fights the resistance of the air, and then rises. Now imagine that you shoot an election similarly into a an area where the waves coming from the sensor push against the electron particles enough to move them from one course, to a new course. One wave won't do it, but if a few thousand to a few million waves push against the electron from the moment it leaves the slit till it hits the screen...well, maybe that's why the interference pattern condenses back to a particle pattern. My biggest question, to qualify that is, do the particle patterns on the side most opposite to sensor move back toward the sensor, stay in the same place, or mover further away from the sensor. If they move back toward the sensor, maybe they are hitting the back of the sensor waves, and get pushed backward as a result. If they stay in the same spot, then maybe its hitting the valley in those waves, and shooting right at the screen. If they move away from the sensor, then they are hitting the front of the sensor waves. It becomes a game of spacetime Plinko.

I always like to fall back on Occam's Razor for things like this - the easiest answer tends to be the right one. You changed the conditions of the experiment by adding an observation element and as soon as you changed the conditions, you got different results. So look for what was changed. The observation apparatus. Surely there has to be some interference that is being created causing the change in behavior. I have no reason to believe that these particles reacted differently because they were being watched. There has to be a simpler and more logical reason for the behavior.

  • Observations that are passive in nature would not alter the nature of the particle being observed. Active observation implies an illumination of the particle utilizing some manner of energy, and observing the result. To passively observe the particle, you must know something of the basic nature of the particle, otherwise the particle goes undetected. To actively observe particle, you must also know the basic nature of the particle, and how it will react to the energy imposed on it, or it will again go unnoticed, or display a result which doesn’t make sense. This also applies in our efforts in attempting to understand and observe dark matter and dark energy.
