If you could put the bag into the all-silver state after leaving it across town by taking all the silver coins out of another bag, that would be a big deal.
So magnetize a sample of iron as a permanent magnet, cut the sample in half, send the second half to the moon, and re-polarize first half here on earth, and show me that it's lunar partner has spontaneously re-magnetized itself in agreement with its earthbound phantom amputated Siamese twin. And then back again, ad infinitum.
(Obviously you don't mean necessarily literally on paper)
Do you claim that the predictions that are made about what is observed are false, or that the interpretation is wrong, or?
Surely you don't mean that by interpreting it in a particular way, it causes different things to happen, so I can't think of anything other than those two.
I think he means that the "entanglement" as understood by general public, i.e. as "I do something to particle A, and suddenly particle B changes" is an invalid way of reading the math; you didn't do anything to B, you merely figured out, by interacting with A, in which world you're in.
You see, this is the thing that kills me when thinking about the quantum world. The Many Worlds interpretation is so clean and obvious, except for one thing - it requires creating a new universe for each quantum entanglement event. Gah!
Of course that does make me think about forking processes and copy-on-write, and the idea that our reality is just a simulation in a computer and that maybe creating new universes is not as expensive as we might at first think...
