1. Wouldn't light then fundamentally have a fuzzy value for its exact arrival time at the detector at all times? If there was a 1% chance that a photon would tunnel, wouldn't there also be a 1% chance that it would resolve slightly closer to the detector as well? Wouldn't the data for the experiment show that 1% of the time they did in fact show up at the same time?
2. I thought I was smart until I started listening to this guy.
3. seem like light speed is really a statistically thing and not a real limit
4. This is a bit off subject but it came to me by watching this . If everything that fell into a black hole is at the singularity wouldn't that break Heisenberg's uncertainty principle , or could it be they just tunnel out of the black hole?
5. How often can quantum tunneling occur? Why does it happen in one instant instead of the other?
   
   Is there a distinct instance where tunneling can occur? If so, when is the next instance? If there were an infinite number of possible instances, wouldn't tunneling always occur at all times?
6. In theory- Would it be able to control quantum tunneling and upscale it, to teleport a human from one location to another?
7. The transistor does NOT rely on quantum tunneling. Just regular old diffusion and drift of electrons. In fact, tunneling is typically an undesired side effect of small transistors.
   
   That doesn't mean quantum tunneling CAN'T be used - several tunneling-based transistors have been proposed. And tunneling IS the basis for flash memory (which is a floating capacitor more than a transistor). But tunneling is not required for transistors to work.
8. the more I understand about quantum mechanics, the least I understand it.
9. Where do you get the music for your videos?
10. For some reason I found that "I'm on the moon" bit incredibly funny.
11. @PBSSpacetime At 2:19 you make an intersting analogy about the probability distibution of macroscopic objet along the De Broglie wave lengh, you talk about the probality distribution collapsing if someone looked at you. Following that thought wouldn't that be also true if you look at yourselve and therefore interacting with yourselve you would collapse the probability distribution.
    Also at 9:06 about the causality principle violation wouldn't that mean that the information is contained not in the particule itself but in it's wavelengh and therefore not being really a violation.
12. Wait wait wait wait wait. If the de Broglie wavelength is the Planck constant divided by momentum, and momentum is mass times velocity, and velocity is motion, and motion is relative, doesn't that mean that the de Broglie wavelength is also dependent on the velocity of the observer?
    This is a great channel by the way keep up the good work
13. you are observing yourself so you will never teleport
14. Most of this video is bullshit and its crazy that people actually accept this "everywhere at once until observed"
15. should have seen this may be a decade back, who knows, might be a Cern or NASA physicist instead of a doctor
16. quantam tunneing kinda still freaks me out because of the whole higgs-boson vaccum theory
17. Illogical explanations belong only in fantasy physics, not in real physics. My new unifying theory solves most of the fundamental problems in physics theory, guaranteed, using only simple, obvious, physically logical explanations. It is for sale, temporarily, before I publish. You can find my videos using 3 search keywords: matter theory marostica. Initially the term "quantum" had to do with "having 1 out of some number of possible discrete quantities". Now, unfortunately, "quantum" is more synonymous with "illogical, mystery, fantasy".
18. That you can be in many places - and TIMES - at once - is something that QM says can happen. Even though it can't yet explain gravity with a good degree of probably being correct, don't ask me about gravity!, holds true in that you were probably around - at least in part - when Jesus was born. When the pyramids were built. When monkeys and apes separated. When that T-rex looked up at the sky and thought, "oh, shit!" It's been 65 million years? It seems like yesterday, god rest those poor dinosaur souls! :(
    
    You have been around since then. The protons in our bodies have been around since protons were invented. The patent ran out, and the proton has been open-hardware ever since.
    
    Somewhere in the Far East, it has been said that the human existence is of all time and space itself. John Lennon wrote a song describing such a future. Danielle Dax covered it, not too badly. A taste for electronics in music is required.
    
    Gotta love those Star Trek sound effects!
19. Collapse of wave function is a wrong description. Its the build up of matter state from waves. Afrer all everything consists of waves until observed. Within a computergame you cannot see more than the horizon. When you move through a 3d game it computes the new area and the old computed area you visited is dissolved again. But not lost because you can go there again. Somewhere the information is stored.
20. At 2:39, you say that humans have de Broglie wavelength couple of magnitudes smaller than plank length. That was a mistake right?
