SPOOKY ACTION AT A DISTANCE EXPLAINED SIMPLY LondonCityGirl – Knowledge

Hi Guys,

Today I’m looking at spooky action at a distance and this video definitely needs a few views if you’re new to the subject :D

As always I hope you enjoy this video and I’ll see you in the next year with plenty more videos as I ramp up production as much as I can.

1. SuperSaiyan UltraGogeta: This video is educational
2. Trevor Jones: What if its wrong and all particles are entangled together and pass the message on through all particles but its that instantaneous that we see it as just 2 particles as there can be only 2 connected at once but still connected in away to the rest that its possible for this to happen over any distance I get its hard to understand what I'm saying but it'd a theory
3. im replying to this comment: I can do these with my fingernails
4. Chief Seadawg: This video is excellent, as entangled particles were explained in a very perspicuous manner. I have read quite a bit on this topic and have spent a great deal of time thinking about it. What is fascinating is that not only the spin, but the locations (Quantum Superposition) of these particles are never revealed until they are observed or measured, such as in the famous "Double-Split Experiment." And the fact that two entangled particles can be separated by the entire length of the universe, yet both instantaneously reveal themselves when measured or observed leads me to believe that not only space and time, but reality itself are not as we think we "understand" them to be. Yes, this is indeed spooky action at a distance! I also wonder just how a particle "decides" whether it will have an up spin or a down spin at the instant it is created? No room for LGBTQs at this level!
5. Prince Gupta: Great video plz make more video on Physics Topics....... Which software you are using to make this type of videos.
6. Danilo Pacheco Martins: Awesome video, but I have a question. If an electron hasn't been observed yet, will it be for certain in a spin up and down state? Or even though it hasn't been observed yet, it might have a defined state?
7. Danilo Pacheco Martins: +Tarang Patil that I had got it. My question is if it hasn't been observed yet, will it be for certain in a super position?
8. Tarang Patil: It will be spin up and down at the same time. This is called Superposition
9. LapSiLap: Watched bells theorem many times.. Didnt understand very much but after watching 5:13 3 times i understood it muuuuuch better! Well done
10. LondonCityGirl – Knowledge: Thank you! :D I'm really pleased to read that! :D :D
11. Amal Murali: Nice explanation
12. zarchy55: I found the video to be very informative. However, with all due respects, it did not explain Spooky Action at a Distance. It merely demonstrated that experimental results are consistent with Spooky Action at a Distance. There was no explanation of how it occurs. It still remains “spooky” in my mind.
13. Jim Pickard: You have made my head spin at a distance proving that action at a distance is possible
14. theShowman: My head is spinning as a result of watching this video ! (That's a compliment BTW, not a criticism). I can't help thinking that some gifted genius will one day will put all this together and give us a 'feel' of what is going on. Maybe we'll be able to travel vast distances and won't be restricted by the speed of light.
15. Andre XX: But is there an explanation of a mechanism whereby two particles separated by light years can communicate? If we could explain this surely it would tell us something very fundamental about the nature of the universe?
16. jugosever: How do we know a pair of entangled particles are still entangled even if they are separated by the entire universe? I mean, there is no way we can have two spin detectors separated by the entire universe.
17. Maya: If system 1 and system 2 are entangled, but you can't access system 2 (because of very large distance, or maybe system 2 is behind a black hole, etc.) you can still notice because you lack information to describe system 1: you can only completely know system 1 if you also know system 2, because part of the information of 1 is encoded in the entanglement between both. When you lack information on something, you have to resort to give probabilities to phenomena. And when you introduce probability distributions in physics, automatically you need the concepts of information, entropy and temperature to describe systems. Systems which are 'complete' on themselves (aren't entangled with anything else) are called pure states, while those which are entangled with something else (and hence have part of their information encoded in the other system) are called mixed. Mixed systems have an entropy and hence temperature, while pure systems do not. This is a way you can distinguish them.
18. Hyper Red: nice :)
19. Cosmic Rift: Spooktober is ovah!
