  1.  @rolandcuthbert784  String Theory predicts certain things, such as supersymmetry. If supersym particles are not found then it fails to pass the test, right?

  2. Semantics? Einstein uses the term "force" 184 times in his book "Relativity" You can say gravity is or is not a force, it doesn't matter to the theory.

  3.  @philcowdall9399  I was very disappointed with her take on superdeterminism. She acted like it was a valid scientific possibility. In fact it is only a philosophical possibility, much like the theory that God put dinosaur bones in the ground to fool people. Except in superdeterminism, every quantum in the history of science is a fake bone like that.

  4. The connection is created locally, but it acts nonlocally.

  5.  @kuribojim3916  Indeed. It's not classical so it's easy to misinterpret. Doesn't the ER = EPR conjecture uses local action and finite speed, actually? The signal travels at c but appears instant/ nonlocal to us because it goes through a wormhole...

  6. I do not expect he is right about AI being impossible. But it hardly seems disproven. Today's AI can't even tell if it's snowing outside.

  7. Science doesn't use proof.

  8. I think he says quantum mechanics is flawed because the schrodinger equation does not describe measurement.

  9. Yes, but we don't know if that gravity is split in half in the two slit experiment, half in each slit.

  10.  @alanrobison4761  If the gravity is not split, which slit does it go through?

  11. so it's either string theory, or nothing?

  12. It's experimentally validated. It takes imagination, but so does the idea of an electron.

  13.  @math6844  Irrelevant. Finding nothing in the kitchen does not prove the dining room is empty. It may of course convince people that it is useless to keep looking. That is a judgement of the human intellect, not proof.

  14. per Copenhagen, a particle can be in a superposition of two states.

  15. correction: one state with a superposition of two different values.

  16.  @cassandrasmith9173  Thank you, good advice! Undefined seems a bit too simplistic. It is not undefined, it is defined as one of two possible values. Unknown also seems too simplistic. It doesn't have a specific value. It's not just in our mind. But that's mostly semantics. More fundamentally, a system in superposition of two values may actually have both of those values. I recall an experiment where a silicon oscillator was put in superposition of "non vibrating" and "vibrating" condition by coupling to a josephson junction. Both conditions had detectable signatures in the data. It seems like both were actualized at the same time. Not undefined, not unknown, but both mutually contradictory states at once.

  17.  @adrianwright8685  yup, that's sensible. Looking in the dark would have a zero percent chance of success.

  18. They don't run the world, tho the materialist paradigm kinda does.

  19. yeah that's where I am now too. it's a probability, it's about the future. when we reach the present, we don't need it.

  20. the aether is quantum. it is now called the "field" and studied by quantum field theory.

  21.  @Thomas-gk42  Yup, it is wrong. Bell and Aspect showed that LOCAL hidden variables cannot explain the results of experiment. (Values that stay unchanged and travel with the particle even when it is in free flight). Nonlocal variables could exist, and local variables could exist too! My cat is a local hidden variable when I don't know where he is. But no matter what, local hidden variables cannot explain Aspect's two slit experiment...

  22.  @Thomas-gk42  interesting. i wonder what would be measured?
    1
  23.  @Thomas-gk42  i mean, how would such an experiment be set up?

  24. It is testable.

  25. agree. never put music over speech, except in a brief intro

  26. String theory was used to predict the viscosity of the QGP. Correctly.

  27.  @philcowdall9399  lol! Hilbert is my 3rd favorite, 4th favorite, 5th...

  28. That is questionable. She advocated denying medical treatment to people for refusing experimental medicine. That's not really acceptable, per Nuremberg trials.

  29. technology, probably

  30. GR has a lot of "why" in it. But we should probably not expect an answers to ultimate 'why' questions from science. If everything has a cause, then there would be no first cause. So there would be no ultimate reason that we could find. If there was a first cause, we would not know why it happened, at least not in the deductive sense of knowledge.

  32. String theory was used to predict the viscosity of the Quark Gluon Plasma, later measured at CERN.

  33. agree. She said people who refuse to take experimental medicine should be denied admission to hospitals. That violates the Nuremberg Code, which was used to prosecute other Nazis. So in this respect she's a medical Nazi.

  34. Those are words for observations. Observations are not cop outs. They are the foundation of science. They may turn out to be misleading words, but since there are many testable theories to explain the observations, there is no cop-out except saying they don't exist.
