User ID: 71952359 United States 12/28/2016 10:19 AM Report Abusive Post Report Copyright Violation | With quantum entanglement there's a 50% chance that both particles are spin up, that we have to call their spin "undefined". Why does this destroy the idea that both particles are created with a definite spin. Why can't we say "both particles are created with a definite spin, but we don't know what the spin is until we measure them, and when we measure one, we know the other one is opposite, and they've been that way since they were created"? Quoting: Anonymous Coward 72646372 Probability is probability until actual measurement determines the real direction and since the other one is always the opposite this is how we know what it would be measured to. What is so spooky about it? Imagine you have a room with random crates which contain green or red apples. You pick one crate, put the half in another empty crate without watching (so you don't now the color yet) and send send it to Timboektoe. When you look what color apples you crates has, you immediately know the color of the apples in the crate in Timboektoe. What's spooky about that? Because the spin isn't set until the measurement is made. Prior to the measurement, the spin is both up and down. Measuring the spin sets it.. then communication needs to occur to synchronize the two particles. Last Edited by Doom Hammer on 12/28/2016 10:26 AM |

They cannot measure it because the act of measuring would cause the spin to go up and down... Well, how could they know the spin goes up and down if they never could measure that? It was going up or down all the time. It's the same intelligence science nonsense as saying the dinosaurs lived 154 million years, 2 hours and 33 seconds ago... |

Space is more likened to static existence as is voltage. Time is more likened to kinetic existence as is current. |

The particles are in a state of superposition until measured. Meaning.. they are both spin up/spin down at the same time until measured. It's not pre-determined. If you remove that one principle.. then what you are suggesting is true. But that's not how the theory works. |

Look up the definition of both. Quoting: Anonymous Coward 72648709 He's right you know Quantum entanglement is spooky because we don't understand the mode of communication between the two entangled particles. It's faster than light speed; we can't observe it. |

Yup. That's why Einstein had a problem with it and said "I like to think that the moon is there even if I am not looking at it." Schrodingers Cat was also a thought experiment to point out the ridiculousness. However, that's what the theory is and it is very successful. It has yet to be proven false. |

Anonymous Coward User ID: 71843037 United States 12/28/2016 02:35 PM Report Abusive Post Report Copyright Violation | The Universe, a whispering gallery The Word is in the Light. Corrupt the Word and All that Is, reacts. Sound bubble tension from the primal explosion Held in sway by the reaction implosion, Like the hand of God bearing an expansive bouquet. Light thusly thrust carries missives of eons. That quasi-static underling is bound universal sub-tension, sub-Om to the Om. Infinite in viscosity, yet frictionless in the infinitesimal. Temporally bound to Source with favored direction Path littered with a wake Path shown by light Spirogram in ouija plane. Self-corrective and reactive Due to all that is action The underling, in perception a slower dynamic, Yet inherently of higher order frequency. The scale is such that a phonon stream could travel As echoes of souls in isentropic cryostasis Thought trains in a massless night Along the boundaries of all that 'was' real. Within the primordial bubble lie the fruits of creation A cornucopia in a woven horn Each fruit a multitude of horns As baby elephants tweeting to the roar of their mothers. Light has memory of where it has been. Expectations arising from thought are sensed As charge propagates throughout all that is mind Charged light therefore anticipating that which is thought. In a gravitonic well, a static field will roll with surface effects due to acoustics (acoustic phonons). In resonance, phonon groups form and a feed sustains the lot. In harmonics, phonon groups decouple, as does the fractal construct of each 'horn.' A construct obtains functionality as a virtue arising from subfunction. Once imbued with such functionality, said construct interacts with all that is. In this universe, we live within a past subfunction, while creation arises thanks to current subfunction within. Which brings us back to the base. A foundation feels all vibrations. Yet to develop order out of all the chaos, useful information is parsed. Distortion ebbs in continuity. Amplitudes wane in subharmonics. What's left is the meekest cry, humbled by suppression, freed of past burden. The process is simplified as the foundation is in all. And the meekest structure dances to the chorus of subfunctions. The halls of records are of images and sounds, information. Yet some would see such as data. Digital archiving is ludicrous to a universe in which each living experiential entity is a 'subuniverse.' Which brings us to holons. And back to whispering galleries. /meanderings -jad |

We seem to think that WE are not affected by quantum entanglement. Our EYES interpret quantum data, yet we do not see the light that our eyes interpret as also entangled. What about the light signals that travels through our brains? This is ALSO entangled. If it's spooky outside of us, it is also spooky INSIDE of us. This would possibly explain many so-called "supernatural" experiences which also include precognition, dreams, dream states, visions and so on. ANY future Theory of Everything would, necessarily, have to include many "unexplainable" things such as NDE, prophetic dreams and visions, and other esoteric experiences. Meditation, concentration and faith may very well have CONCRETE results. Experimentation implies that we do have concrete results by simple observation. Entanglement goes a long way towards showing EVIDENCE for this. Whether we realize it or not, we are on the cusp of amazing new discoveries. I believe it will be seen that the "mysterious" new engine will show these principles in action. After all, it also uses microwaves to somehow produce thrust. Again, we are talking about entangled "radiation". We are definitely going to have to think outside of the box on these things. The TRUTH is stranger than FICTION. |

Why does this destroy the idea that both particles are created with a definite spin. Quoting: Anonymous Coward 72646372 Why can't we say "both particles are created with a definite spin, but we don't know what the spin is until we measure them... It doesn't. If all we could do with particles, was to either measure spin up or spin down with a 50% chance of getting either, the it would become a philosophical question if or not there is spooky action at a distance. Think of a pair of boxes, each containing a pair of gloves. When you open one box, you either get the right hand or the left hand glove. If you get the right hand glove and someone opens the other box, he will always find the left hand glove inside and vice versa. This behaviour can be programmed into the boxes at creation time. No matter how many pair of boxes you try, they would always get it right if programmed properly. If i gave you a pair of boxes and told you that those are magical boxes, which are not programmed but magically communicate the information on if you got the right or left hand glove when you opened it to the other box, such that the other box would output the proper glove when you opened it, you would have no means to prove that those boxes are really magically or they were just programmed at creation time to output the proper glove. However, if you were to consider a pair of boxes you can either open from the top or from the front, things become different. When you open one box from the top, you will find a glove. Opening the box from the front, you will find a coin. Let's call them box A and B. When you open box A from the top, you will find a glove as already mentioned. Subsequently if you were to open box B from the top, you would either find a glove or coin with a 50% chance. You would also find a glove or a coin with a 50% chance if you were to open box B from the front. however: Open the box A from the front, would always give you a coin and when opening box B you would also get a coin 100% of the times independent on if you open the top or front. This is not a behaviour you could possibly program at creation time into the boxes, because you cannot know if the user will either open the top or the front of the box. If the boxes were truly magical, able to communicate instantaneously at a distance, they could get this right 100% of the time If you however programmed the best strategy into the boxes at creation time, you might be able to get it right over 75% of the times, but certainly not 100% unless you got very lucky. This is just an analogy to the way more complex case of how physicists had to device an experiment which proves that those entangled photons are truly communicating instantaneously at a distance. They measure the spin at different angles which is analogues to opening the top or the front of the magic box and the outcomes are far more complex and harder to interpret but in essence they are doing the same as with the boxes i described above. They prove that even with the best strategy programmed into the entangled photons at creation time, you would not be able to guess the outcome correctly as often as if there was spooky action at a distance involved. |

Right now it's like hitting a cue ball in a pool game, hitting the ball without understanding they if you hit it off center or will give the ball a spin in either direction. |
