      wtf, if you are stupid but you dont know it yet it does not mean you are not stupid !, how does the pilot theory has anything to do with locality ?!, or your missinterpretation of it ? wtf is wrong with you , haa ? if you spin 2 electrons in opposide directions YOU ALREADY KNOW THEY ARE SPINNING IN OPPOSIDE DIECTIONS, you just dont know which one is spinning in which direction, so as soon as you find the spin of one electron you combine that WITH THE INFORMATION YOU ALREADY HAVE and determine the spin of the second one, this has nothing to do with locality, it does not matter where you Move the second one, you already have the information. htf can smart people be this dumb ? are you so desperate to fin an explanation that you simply ignore parts of the ecuation to fit the result you already expected ?!

    I dont know the underlying math in pilot wave theory but, by the way that it's being explained, it reminds me of modal analysis and other studies I've done in signal analysis during my engineering degree. Rather than thinking of the two particles being interlocked independently from space (indicating information travelling at extremely high velocities in order to guarantee their states are interlinked) couldn't it be that they normally match a "wave" which is independent from space itself? A "natural frequency", if you will accept my analogy with modal analysis, where these particles fit in the nodes of such waves; hence retaining a similar behavior as long as they stay fixed to the nodes of this wave independent from time and space. In order for this to be valid, though, an infinite number of particles all fitting in separate nodes of this hypothetical "wave" would all retain the same properties of the particle under test. Does anyone more knowledgeable know whether this analogy I brought up is a load of garbage or not? ;P

    2 things. 1) QM properties of individual particles contribute to the QM properties of larger ensembles, and above some threshold ensemble size, the QM properties "smear out" (else we would have to choose which contribute and which don't), resulting in the classical properties we know and love. 2) I think it's Bell's theorem that showed that entanglement is more than just deduction. I.e., if we know there are a total of two states and two particles, and after separating them, we observe one, we subtract the observed state from the list of possibilities, leaving only one state possible, thus not requiring FTL info. Bell's theorem showed this is not true...if I remember right.

    The shroedingers cat experiment is a horrible example imo, unless you're trying to prove that the particle is indeed in one state or another.. Because you don't actually change the cats state by measuring it. The cat is indeed either alive or dead, and the only thing that changes is your knowledge, as the measurement has no effect on the cat.

    Actually the rudimentary roots of laser light research comes from crystallography, sapphires and rubies create a strange star effect simetimes. We typically use rubies to make lasers by pumping light into a reflective cylinder and aligning the crystal so that it bounces light to the front and back of the cylinder until it comes out of that tiny area of the ruby that only allows a thin plane of light to exit. Quantum theory helped explain it, not to create it, correct?

    Peter fills a bottle with a pitcher and put it in the trunk of a car. Mike, who doesn't know whether the all or half of the water is poured, drives the car for 10 miles. Before he stops and checks the bottle, the pitcher back a the starting point can be either empty or half full. That, however, is only the case in his knowledge space. In Peter's knowledge space, the amount of water still in the pitcher is already known. The information doesn't teleport 2 miles instantly when Mike opens his bottle, it's just that he doesn't know it yet. Should there be any information that travels, it should be inside Mike's brain, not over 10 miles, and It takes time to deduce that half a bottle means half a pitcher. Say if the universe is run on an engine inside a computer, and it can be paused to examine the exact speed and position of any particle. Then the information is there all the time, we just have no way to get it. It's beyond our knowledge space, which is limited by our methods, not necessary beyond every intelligent being's knowledge space, nor beyond the universal/absolute knowledge space, should there be one. Photons that interact with the pitcher carry information for a suitable observer. The bottle that got carried away can be said to contain extractable information. These carriers of information don't travel instantly. The knowledge inside the brain can arguably be considered information, but this conscious information(knowledge) should not be confused with physics information. If a bird knocks over and empties the pitcher after Mike leaves, it will be possible that Mike sees a half full bottle and thinks that the pitcher is half full. How then, can he get a wrong information, which teleports back to the pitcher?

    Regarding the speed of light being the universal speed limit for everything... we've already proven you can cheat that. By bending space/time you can cheat by moving between two points without the travel time between them. Makes sense that particles may be able to do that too... right?

    Yeah but things can effect things not in thier immediate surroundings without sending a "traveling" signal or message. You have seen this it's called gears. Gears all start turning see the same time with a little gap for the space between the teeth. The universe often functions like waves making particles because inertial energy gives a portion of existing fabric of the universe mass. Like a set of gears though an already excusing standing waves that have created a network of simultaneously moving parts can communicate information in the form of specific inertia to make it look like a partial was at one end and then just appears at the other end. This duplicate however simply interacted with something like this at one end and communicated it's inertial energy to the other end instantaneously. Similarly entangled particles are capable of staying entangled by creating a standard wave along it's path as the two entangled particles travel apart and when one is flipped on the other end the information initially is communicated via spooky action without the usual need for time for a traveling wave to communicate the effects of that traveling inertia on it's immediate surroundings.

    Ugh, I like cats. In my ideal world I would end getting eaten by one, that's how much I like them. So I'm not too fond of that guy Schrödinger. Luckily there's another example (maybe devised by a cat-lover) that shows much the same, and actually at the same time gets to examplify entanglement. Instead of cats you have two friends, two identical boxes and two equally proportioned balls, one red and one white. Your one friend now goes to the opposite end of the world while your other friend grabs the boxes and the balls and takes them with him to a place equally far to both of you and your first friend. He now puts each ball in each identical box and brings them to the post-office with a note, please mail these boxes to these receipients. The clerc then, upon coming back from lunchbreak, writes your adress on one box and your friend's adress on the other and sends them off in the system. A couple of weeks later each box have arrived at their destinations, half a world a part. Right now, *both* balls are in a superposition due to the Copenhagen interpretation. The minute - the second, nay, the split-nano-femtosecond - you open your box and look inside it, the state of the ball will decay into being either red or white. Just like with the cat and it's highly elaborate scheme to ensure maximum randomness. But on top you at the same very instant have caused the state of the ball that is in your friend's box to decay as well - even without him neccessarily having looked yet! Entanglement, ta-daa.

    Doesnt that just mean that we need better methods to "observe" particles, as doing so alters the results? We live in a deterministic world, so i find it very hard to wrap my head around that concept. Its like chaining the poison gas to the opening of the door. Sure, you have observed the status of the cat, but also changed the state of the poor cat. The original state has not been uncovered, but the information of that state is still there.

    I think it is important to keep in mind, that the different interpretations of quantum theory are models describing real quantum phenomena! Most likely, there is no definitive interpretation, because no physical (or - to my best knowledge - any other) model, was ever able to capture every part of the phenomenon it described in all detail on all scales. That's why science relies on various models of the same phenomenon, each with emphasis on different parts (or scales) of said phenomenon. The real question is, which models are able to coexist without fundamental contradictions to each other. I don't think that the different interpretations of quantum theory show these fundamental contradictions, even if that appears to be the case! The key flaws in humanitie's ability to solve those contradictions and create a more accurate approximation to real quantum phenoma lies in it's limited perception of the phenomena themselves and time as a phenomenon which is described by a model based mostly in human perception of it. My suggestion would be, that most of the different interpretations contradict each other, because the describe quantum phenomena with emphasis on their observed (or predicted) behaviour in different temporal dimensions. For example, lets take the many-worlds-interpretation and the wave-collapse-interpretation (or Copenhagen interpretation): The collapse of a wave function into a particle, or the termination of a state superposition in a particle and it's adaptation of a single state with an elimination of all other possible states, allows two (or more) interpretations based on how many temporal dimensions one can observe. Human beings experience time as one dimensional. Their frame of temporal perception is a single point on a line, where what lies behind is inaccessable and what lies in front is unpredictable but unavoidable. From this point of view the assumption, that every state of superposition we are not able to observe after the collapse of the wave function is eliminated from the equation, is fully understandable. But if we assume that time is/has a multidimensional 'structure' (which most evidence points to), and try to imagine what the collapse of a wave function looks like for beings with two dimensional perception of time: Instead of the 1D-perception of a moment in a timeline and the elimination of states in the collapse, a being experiencing two temporal dimensions, would perceive time as a (freely accessable) line in plane (with inaccessable parallel lines) and in this frame of temporal perception, the collapse of the wave function would most likely look like all possible states of the particle are spread among all the parallel lines, observable, but inaccessable. To summerize this: 0. Quantum phenomena (and every other processes) occur in a multidimensional temporal structure. 1. The wave-collapse-interpretation is a model, which describes these phenomena as observed in one temporal dimension. 2. The many-worlds-interpretation is a model, which describes these phenomena as (likely) observed in (at least) two temporal dimensions. 3. Each interpretation serves best, when applied in it's specific frame of perception and holds scientific plausiblility, when viewed in in said specific frame of perception, without contradicting each other fundamentally.

    I have a question on how to get around locality. If a wormhole can connect any to points in the universe, could two particles interact through a wormhole giving the illusion they are interacting across the universe faster than light? Can the particles on each side of the wormhole be considered local because they can interact? If so, any particles can interact with any other particles in space meaning any point in space would be local to any other point in space making all of space local.

    Both theories are flawed because they are dependent on the assumption of individuality between particles, energy, matter. There is no “signal” traveling faster than the speed of light, they are the same particle, experiencing different realities, within the same universe. *Both* realities are true, as they are when observed.

    If there are waves in an ocean, I can send out two croc shoes in opposite directions. They will both be effected by the same waves. So even if I can't see the wave directly I could infer the waves by watching the flotsam.

    "There are a number of different interpretations of quantum mechanics." Sorry Hank, "a number" is singular. LEARN GRAMMAR!

      Chrome Cobra pay close attention pinhead. It is irrelevant if the subject is plural if the sentence is referring to that subject as being comprised of a singular group. For instance, if one says "a flock of geese" that flock is still singular notwithstanding the fact that it is consist of a multitude of geese.

      And it's "Sorry, Hank, ..." so YOU need to learn proper grammar. You cannot even grasp it within your own comment. Stay stupid on stupid channels. Leave the smart stuff for the adults, kid.

      But because "interpretations" is plural it makes it correct English. It says, in kindergarten talk so you comprehend it, that there are many individual ways. Ignorant.

    wtf, if you are stupid but you dont know it yet it does not mean you are not stupid !, how does the pilot theory has anything to do with locality ?!, or your missinterpretation of it ? wtf is wrong with you , haa ? if you spin 2 electrons in opposide directions YOU ALREADY KNOW THEY ARE SPINNING IN OPPOSIDE DIECTIONS, you just dont know which one is spinning in which direction, so as soon as you find the spin of one electron you combine that WITH THE INFORMATION YOU ALREADY HAVE and determine the spin of the second one, this has nothing to do with locality, it does not matter where you Move the second one, you already have the information. htf can smart people be this dumb ? are you so desperate to fin an explanation that you simply ignore parts of the ecuation to fit the result you already expected ?!

    If you don't check the cat box for a long time and you start to smell a decayed cat, is there both a dead cat and a smelly cat in there?

    Is there an episode where everyone on the SciShow team or teams is introduced and their credentials, ocupations, etc. are introduced to the audience? If not, can we get one? I'm very curious about who everyone on screen and behind the scenes are and what they do. I'd also like to know what kind of education everyone has. I'm not trying to imply anything or upset anyone, I'm just curious.

    How does Copenhagen make more sense? It's just saying that locality isn't a thing sometimes because we don't want it to be all the time... right?

    How about the cat's observation? The cat observes the state in the box and thus the state becomes one deterministic state once observed. So the cat is either dead or alive in the box not both.

    I have a strong hunch that everybody has missed the point. The quantum state exists in one place only. Each persons individual mind. The cats status is set,it is dead or it is alive. Each individual conciousness that is aware of the box and its contents,is where the superposition exists. Not a huge leap to understand the links to a multiverse theory that works. If you think hard enough.

    Yes but why are these theories based on observation? Copenhagen theory violates locality based on the idea that a particle requires observation to establish superposition. No other interaction is required beyond observation... And the Quantum Gravity theory requires a conscious observer but points at the universe as a conscious observer...
