The answer is somewhere in here but the mechanic may or may not be here.>> <<@1243spirit says : when they sayed + and a - knows already what they are with the hidden veritable dasent it make then quantum in Tangled?? My brain just made that connection can some make sure if im getting it correct or i missed the point and should rewatch the video>> <<@adotcm says : Why tf did I think that was sperm>> <<@NiravThekare says : I understand no sh*t but watched the whole video>> <<@masterelen-c5f says : That said, there are some interesting exceptions that appear to be faster than light but don't actually violate Einstein's theory of relativity: The expansion of the universe: Space itself can expand faster than light. Very distant galaxies can recede from us at an effective speed greater than c because it's the space between us that's stretching—not the galaxies moving through space. Quantum entanglement: Two entangled particles show correlated behavior instantly, even when separated by great distances. This might seem like faster-than-light communication, but it cannot be used to send information, so it doesn't break relativity. Phase and group velocities: Under certain conditions, the peaks of waves or interference patterns can move faster than light. However, these do not carry usable information or energy faster than light. Hypothetical particles (tachyons): Physicists have proposed particles that would always move faster than light, called tachyons. However, there is no experimental evidence that tachyons exist, and they create serious theoretical problems such as violations of causality. Einstein's special relativity predicts that: An object with mass requires more and more energy to accelerate. As it approaches the speed of light, the required energy approaches infinity. Therefore, no object with mass can be accelerated to or beyond the speed of light. So, based on everything we've observed so far, nothing carrying matter, energy, or information has ever been shown to travel faster than light through space.>> <<@pono_ouiji says : The "speed" of light or rather the reproduction of light through octave wave fields is not constant as presumed, the illusory reproduction of motion is based upon the medium of which it's observed projectorary consists whithin. Henceforth, if the observable existence is warped and possibly experienced as temporary emotional discomfort then who is to distinguish the difference in fields of distortion when all means of measurements within it's field is distorted as the surrounding environment>> <<@normalguy-kt8wk says : Einstein biggest blunder isn't the cosmological constant but it is chasing to prove that quantum mechanics is wrong.>> <<@KnowALot says : Can high-pressure air bend a laser beam?>> <<@saikatalam150 says : Did anyone noticed that they are eating 3 half portion burgers. there should be 4 half portions mathematically. where is the remaining half portion??? did the cameraman take it??? or "veritasium" has something to do with this???>> <<@mritunjoydas336 says : Well, if many world interpretation is correct, does every subatomic particle measurement create a new world with different outcomes? If yes, does the information about the creation of different worlds travel at the speed of light? Does every "world" have the same stretch in spacetime? If we consider the branching of the worlds because of the measurements, is that branching at lightspeed? I'm confused!!>> <<@LawtonJucaro says : I am not a physicist, but what if two entangled particles aren't really separated? What if they're connected by something we can't see, perhaps through a fourth spatial dimension, like two points on a rope?>> <<@SteveBD6-11 says : "There Is Something Faster Than Light" it's spacetime, don't waste 44 minutes of your life on this>> <<@GongMaster says : Imagination is also faster than the speed of light. I can imagine travelling from one point to the next in an instant.>> <<@glenswada says : Entangled particles don’t feel time.>> <<@erikfreeman2472 says : 😲>> <<@calebcase80 says : Bad news>> <<@meltyend says : It's me, im faster than light>> <<@MrDv1lowes says : Wouldn't the wave function cause everything measured on that plane to be instant? If the origin of particle was moving from it's source linearly (just cause for measurement), from that point it's no longer linear, but a wave instead. Where equally on that infinite plane the particle now exists. Meaning that no matter where you measure it, all other traveled no longer exist with the exception of the symmetrical. Both traveled and exist on that same plane. Measure one causes the opposite to collapse instantly. You can measure the speed between both at the point of collapse in a line because all positions of the particle existed at the same time on that line.>> <<@SujeetSingh-rd7oc says : Mass!!>> <<@jonpomerance-trifts6113 says : 30:55 *positrons (not protons)>> <<@SGT_Chemistry says : How does the many worlds hypothesis deal with the 1st law of thermodynamics?>> <<@SaravananRamamoorthy-o4f says : 2:17 proof by coontradiction>> <<@paulkelly2928 says : The thing that can travel faster than light is the dark. Look at its ability to get out of the way of the light. How fast can shadow travel?>> <<@alphasky03 says : Are we being told the multiverse exists?>> <<@Kammino11110 says : i had no clue how quantum physics work... until I saw a random comment about socks>> <<@ronsimpson3198 says : It is not a double toroidal object it is triple toroidal by design. It is one of the secrets of field theory>> <<@rodrigoguerra2836 says : The problem here is this fiction of a "classical" observer: it makes no sense. Imagine that you're a professor and you ask your student to go measure something. Does the wavefunction collapse when they measure it, or when they tell you what they measured? The solution is "hidden variables". For the positron-electron pair, the spins are fixed when they are produced and so there is only one answer in the envelope. Quantum typicality then guarantees that if you repeat the experiment over and over again you will get answers with probability equal to the square of the wavefunction. No action at a distance or spookiness necessary>> <<@Stibiumowl-oder-kurz-Stibi says : Could so.eone more smart than me if the video's problem can be resolved by apliing solutions from the twin padadox with the non-universality of simoltaneously-ness of events? I was wondering if the twin paradox could be a solution for the Videos paradox, namely 37:25. If in the reference frame of Red Envelope Particle, particle Red sees itself at rest and Blue moving away at arbitrarily high speed. So Blue ages slower, if age here is time until it is due to be measured, so the Red observes itself beeing measured at first. So it has time to tell the entangled Blue how to spin-orient correctly as Blue has much more time until it is measured. But from Blues perspective, Red ages slower i.e. is measured later and is open to be told how to orient spin. So each particle thinks it was measured first and told the other one how to spin. And had the time to tell this with just light speed because the particles weren't seperated faster than light.>> <<@trim-h9y says : The thing about quantum physics is i don't understand it ... But nobody understands it😂😂😂>> <<@gbail9566 says : Quantum Field Theory may suggest all particles are one, thus neither local nor non-local!>> <<@wlan246 says : 4:33 Probability "travels" faster than light—but as far as we know, probability is not a particle or a wave. The wave function collapse must be a metaphysical phenomenon, in that it is exempt from the limitations to which the matter and energy that are "in" the universe are subject. Edit: To put it differently, the wave function isn't "in" spacetime, carrying information from one point to another, but a phenomenon "behind" spacetime, the effects of which operate instantaneously.>> <<@ThePaulsen1992 says : Enjoyed the video but I'm pretty disappointed the actual dichomoty that bell's theorem implies was not talked about... That local causality and statistical independence can't be true simultaneously. In other words, you can save local causality if you accept superdeterminism; i.e. that the measurement outcome of the EPR experiment is correlated with its past light cone of influences. Many worlds theory is not the only alternative. While most pop science media usually glosses over this fact when discussing the topic, I was honestly surprised it wasn't mentioned at all in this video... You guys are usually so good when it comes to stuff like this! Fingers crossed we might get a follow-up video one day about it 🤞>> <<@reborn5125 says : Its me>> <<@claudeenckels2117 says : La vitesse absolue est la vitesse qui n'a plus de limites ... Dans ce cas, ce n'est même plus nécessaire de la mesurer.>> <<@leovolin7525 says : 20mln pple cheated by the crappy title! I do not think these are real thinkers.>> <<@Crispyfry080-0.0 says : Ok where is young sheldon…>> <<@gopalkrishnamurtykarri-xy2om says : Anyone heard of tachyon>> <<@wgranicki says : The fact, that the only time the expression "spooky action at a distance" is mentioned in this video is during an ad, is a kind of disgrace>> <<@publicinrage says : You all presuppose the wave is an arc. What is the evidence that the wave is an arc?>> <<@MistiMoan says : 39:54 not sure I can agree you can't send information backwards in time. And I was coming across all of this stuff when I was trying to explain precognition which I have experienced uncontrollably since I was about 15 years old. I turn 42 in a few weeks. I've been working on trying to write a paper on a scientific explanation for this.>> <<@Cogumass says : 10>> <<@SweetFeet-w1e says : so cool>> <<@FuzzOffier says : 8 mins>> <<@ThaMassDebater says : WARNING- Dumb analogy and question coming... Who remebers the Bruce Lee movie, Enter the Dragon? Who recalls the scene with all of the mirrors? If observation breaks the wave function, even at a distance, why do you see multiple mirrors with images on them? If mirror one (Observer) blocks, intercepts or interacts with the light wave, wouldn't the wave function to the other images on the other mirrors also collapse? Why can you still see the images on all of the other mirrors if wave collapse occurs even at a distance. I know im probably way off the mark with my interpretation so can someone please explain?>> <<@Moreno.P says : i just dont like how this women Explain>> <<@willivonen says : There is no barrier to particle decay.😊>> <<@jondo7680 says : Many worlds makes no sense and does not solve the problem. If you get a + you are in + world. How does her envelope know that they are in + world? If you two meet again, which mechanism makes sure that you meet the one from your world and not the wrong one? When did the decision about which world you are in happen? If there is no faster than light collapse, it must been decided earlier, which you say predicts 33% not 25%. Many worlds just brings that time stamp back to the big bang or earlier, because that decision must always have applied and you must always have lived in that world. And no if you say you split the world during the measurement (where the f do you get the energy to split the whole universe? Energy is a reserved term where the f do you get what ever that's necessary to do so?) then you have to split the universe everywhere. Do you know how big the universe is? So applying that split at the other edge of the universe doesn't need to be faster than light? What about her place how fast does her room know that you are now split and became the + world? Manny world solves nothing but is good to sell books or keep people watching. It just moves the problem elsewhere. Pilot wave is the much more promising interpretation. At least it got mentioned this time.>> <<@shalinis873 says : We must be in fourth dimension to prove what is actually happening coz in fourth dimensional thought experiment we can be in both areas where the electron and positron are, at the same time. I'm I right>> <<@kurkync says : I think what is missed here is WHY there is 1/4 and 3/4 disagreement rate predicted by quantum mechanics. My understanding is that the first measurement wave function collapse "causes" the spin to point directly towards + or - . This, according to Malus's law, causes the probability of opposite spin going towards + and - to be 3/4 and 1/4 respectively if the machine is tilted 120 degrees. If the particles somehow "agreed" on the spin prior to measurement then the second measurement would be based on the "agreed" spin and show different probability.>>
