  1. That's probably not the worst metaphor. I never played the game. Are there irreversible consequences once you find something? If there are, then we are getting close.

  2. Which one? We invented so many of them. ;-)

  3. Logic isn't flawed. Logic describes the behavior of classical objects. Quanta are not objects. Quanta are small amounts of energy. If we want to describe quanta correctly we have to use non-commutative algebras. Logic is a commutative algebra... which explains in trivial mathematical terms why it can not possibly give the correct results.

  4.  @johndemore6402  We found the right answer to quantum mechanics in 1927. You are almost a century behind. :-)

  5.  @johndemore6402  Exactly. Why would it matter to me that you are making a fool of yourself? :-)

  6.  @johndemore6402  Correct answer: It doesn't. ;-)

  7.  @johndemore6402  Awh, you are so cute when you are feeling sorry for yourself. ;-)

  8. No, what they mean is "local realism". Local realism is mostly just a newfangled term for "Galilean physics" where everything was determined by the physical values in every given spacetime point. Local realism basically went out the window with special relativity, already, the lesser minds just didn't notice it.

  9. We have figured this out in 1927. You are a little late with catching up. ;-)

  10. Why are you telling is that you don't understand physics, though? ;-)

  11. You have seen communicating particles? You and who else? ;-)

  12.  @balduin7708  Yes, it tells me that absolutely nothing happened. If you don't understand what I mean by that, then you are simply telling me that you don't understand physics. ;-)

  13. Why not? I have four coins, two nickels and two dimes. At the beginning of the experiment I randomly select two coins and send them to Aretha. I take the other two coins and send them to Bethany. Aretha looks at her two coins and finds that she has two nickels. She automatically knows that Bethany has to have two dimes. If she finds one dime and one nickel then it's clear that Bethany also has one of each. That's entanglement with coins. Not a problem.

  14.  @davidhess6593  I didn't say that Einstein was right. A physicist being right or wrong about something makes no difference to nature. If you don't understand that, then you don't understand science to begin with. Entanglement is simply a local conservation law acting on a quantum system. What is the action of a local conservation law? Nothing. It simply does nothing to either energy, momentum, angular momentum or charge. What's hard to understand about nothing happening? Please explain to me why you are having problems with it. :-)

  15. The universe is real, it's just not locally realist. It was never locally realist, we just didn't know better. These kinds of things are remnants of Galilean physics that still keeps spooking around in people's minds. Why do they do that? Because we are still teaching physics like it's the 19th century and we are pretending to high school students that Newton was essentially correct minus some "minor" modification by quantum mechanics and relativity. That's simply not so. Newton is almost 100% wrong. It was always almost 100% wrong, we just didn't know better. What we should be doing is start teaching physics from a modern perspective and then derive Newton as a very useful but almost insular corner case. If we did that, then all these random philosophical musings about the structure of the world would go away in no time.

  16. These folks are simply playing a game of telephone. What physicist were discussing was the (false) philosophical notion of "local realism", which can be trivially ruled out. In YouTube videos that appeal to the completely braindead "local realism" is now replaced with "reality", which are two different pairs of shoes to begin with.

  17. Get yourself a heavy stone and drop it on your big toe. It never fails to prove that the universe is perfectly real. :-)

  18. How do we know what? How quantum mechanics works? It took about 100 years of experiments and 20 years of very hard guessing. In hindsight it's trivial and one can derive it in about half a dozen pages of slightly above high school algebra from a set of mathematical axioms that are named after Kolmogorov. Hindsight is always 20/20. ;-)
