2. Anyone watching this in 2019?
   Lol, jk

3. A falling tree will make a sound even if nobody is listening. Moon is up there if the calendar says so, even if it is cloudy. We humans are just not so special that we can shape the universe though our observations. Me thinks.

4. Why does the audience sound like they're turning into water when they applaud?

5. Perhaps, measure a gazzilionth of a second prior and post to the measurement.

6. I love Brian Greene! XO

7. What qualities make a Ruediger Schack better than other shacks?

8. omg who sings that version of Rocketman at the end?

9. I will explain it to everyone, but only once, and if you ask the question nicely

10. Wow, how did you ever find such a diverse panel?

11. I like how the arrogance of these scientists about their disbelief in God makes them feel as if God truly existed He would have to bend the knee to them so that they could have 100% evidence of His existence.
    Under the similar order of ideas, I like how arrogant religious people are towards these atheist scientists as if somehow, they, the religious people are representing God, personally, without knowing that, from the unknown , God is probably watching with delight how these scientists are trying to understand Creation at its core.

12. Topic is the same topic, but I liked the animations.

13. This is quite a good one!! Brian Greene is always a good host!!!

14. Hmm.. perhaps the experiment suggests that the issue is not with the particle but with that which exists everywhere even in a vacuum. That is what behaves as a wave when uninterrupted by observation and the particle simply flows through it. So when you think you have a controlled experiment you actually have something you can’t control or see interfering with it.

15. I love learning about physics from all the greats that follow different approaches discussing ways to nail down THE approach.

16. Brian, Yours is entertainment.  [Aussie in BC]

17. Still stuck to the same point… 2018 has passed (well almost, it's christmas in 2 days).

18. its like putting the particle through another set of unseen slits. There is a wave we don't know. Hello

19. There is an unseen wave between the double slit and the screen that makes the particles show the way they do. Imagine a wave form going horizontally left to right or right to left that diverts the particle so it has to go one way or the other. Sort of like a plinko machine but at a constant . Its not rocket science. Damn! Come on!!!! Really????

20. I would like to hear an opinion of someone from the Fermilab (who is expert in pair creation, e-p annihilation and about how it looks like), that what he thinks about that part of the thought experiment, when they talk about one single electron let through to the sliced hole. Because I have to laugh hard, when they drawing the path of one single electron on a straight line.

21. Approach of physical theory for next decade.

22. Very interesting.

23. If travelers from "the many worlds" has visited us then I assume we will be able to travel to them? How do know? I have seen these travelers.

24. These 5 Giant Brains Don’t know what the hell they’re talking about!

    98 minutes of incoherent delusional shamanistic Rambling & Cretinous Gibberings

25. Unfortunately Professor Erwin Cory was not here to tell us the truth about everything….Or maybe he was….

26. Why is the speed of light so much faster than the speed of sound. Why try to tie the universes quantum and relative equations together. None of this means anything. Wonder is so much more rewarding than thinking you have a grip on anything. Like a spark in the wind life is too short to worry about anything but having fun.

27. I remember seeing an earlier version of this where Brian Green gets nasty with Ruediger after he does his coin flip demonstration. They edited it out.

28. What kind of asshole wears no socks to this kind of thing? Jesus fucking christ put your dirty feet away. And he answers things by starting off with "Look…" as if to be the final authority on each subject.

29. I barely know what im talking about but is it possible that our biggest challenge in quantum mechanics is that we are in an ever changing state of space due to the expansion of the universe so data may not correlate because we have shifted to an entirely different position in space and time?

30. of the infinite being possible , to think that a human can know anything at all as fact, is purely conceit

31. The. Quantum waves have existed around every Conner in the universe.

32. By assuming light doesn't travel in a medium, it is obvious that physicists can only explain the double slit experiment by assuming that photons exists with a probability density function. BTW, photon is nothing more than an energy chunk but when it travels through "the medium", it will disrupt the electromagnetic field and who knows what else! A swimmer swimming through the double slit will affect (interfere with) any other swimmers because of the water wave he/she created. The swimmer is not a wave, instead the swimmer created the wave. If a photon disrupts the medium that it travels in, all following photons will be affected and hence you see an interference pattern! This same phenomenon applies to an electron too, obviously. What's the big deal here? Observe our nature, instead of hiding yourself in the lab, and you will understand our real world better!

    BTW, the Schrodinger's wave equation does not derive or require a probabilistic solution. Fitting a probability density function into the Schrodinger's equation is a silly ad hoc assumption made by Born just for the sake of finding a closed form solution for the wave equation. The entire field of modern physics is totally messed up!

33. The electron is just a chunk of bent space, and you are looking at a "Dualistic Topology" of space-time. I've got some videos about this and have been working quite a bit on the math of "dualistic topology". It's not really mysterious if you have dualistic topology. Hint >>> The discrete set {0,1} and the continuous open interval (0,1) are Equivalent. Whether you ask which way, or not ask which way, this is really a topological litmus test for continuity or discreteness. This topological litmus test is inherent to the double slit experiment and you guys just are not understanding that because it is too simple. Wave and particle are both correct, due to equivalence.

34. Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality.

35. seriously organised

36. 1:35:22, I like the closing music!

37. Maybe the problem is with the measuring device, or the act of measuring in itself. Maybe the wave/particle relationship is actually another field, and our measurements are exciting it. Maybe there is a 'measurement' field there-by effecting the outcome.

38. cubism sounds a little like one of the anthropic principles thought up in the 70s same with many worlds sounds like the strong anthropic

39. "It`s a probabilistic scoreboard and it`s a HIIIIGH probability" ?

40. I like the word quantum physics better

41. dippy wrong

42. Has this experiment been done in a gravity free environment? If so? Would the line pattern change to a circle pattern?

43. It makes you wonder if reality is sort of like pixels on a computer screen. Except pixels that are in all directions are atoms and molecules. And when something "travels" through space, we travel through those atoms and molecules like pixels on a pc monitor. Those atoms/molecules simply change, giving us the impression that we're traveling around them, when we're actually just traveling "through" them.
    If something like one single atom is shot through the slot, only that row of atoms is moved. When many atoms are shot through the slits, they create movement to adjacent atoms all around, creating that wave of motion through the slits, emerging on the other side as a wave when atoms move through. On the other side of the slits, it's as if water is poured between and the wave expands.
    ?

44. When someone lectures and continuously put their hand in their pocket are they playing pocket pool to keep things lively?

45. the reality of now collapses down from a possibly infinite array of probabilities as we choose through our free will to actualize what reality we live in the future.

46. Right now. Waves are showing us what was.

    We can treat them as what is or what was.

47. Why does morphing from wave to particle mystify us so much, when we find the same morphing duality throughout nature? I.E. at the science festival the audience forms the wave, it applauds in tandem, it laughs in tandem, we perceive it as an amorphous
    organic whole, and it acts as such. However, if the camera zooms into a close up of an individual asking a question, the wave pattern collapses into atomization, the crowd is no longer an amorphous mass, it morphs into individual particles.

    But it's still a wave, we still know the crowd function is there, we know that it's only briefly collapsed. So the audience briefly sits in two positions at the same time,

    Maybe if we had observational devices that could span the micro and the macro universes at the same time, maybe we'd see that reality at our level also demonstrates spooky distance, super positions etc. It's just we only have the ability to see really small stuff under magnification. We have no ability to see how atoms are behaving at the macro level. Perhaps they are morphing back and forth between waves and particles, we just
    have no ability to observe the process. In other words, we can't observe the micro properties of a crowd. Perhaps if we could, we'd see interference patterns, we'd see entanglement?
