(My understanding; I only took one course in quantum mechanics)
Arguably the information that you "gained" was predetermined when you decided which colored ball to place in which box. You didn't gain any knowledge that you couldn't have known before you were teleported 5,000 ly away.
What's also more difficult is that the balls wouldn't have definitive colors, but exist in a probabilistic state / superposition. But you couldn't send the message "I have a red ball" to the individual 5,000 ly away because collapsing your ball's wave will be random and you can't determine which color you want. You could "mistakenly" collapse your ball to blue, not red.
- russdill 6y agoThis big missing piece here is that it's not a simple red/blue property. Spin is the easiest to understand. When you measure, the spin will either measure up, or down. The key though is you can measure spin against any angle. If you measure the spin of the two particles at the same angle, you will get opposite answers. And you can choose what angle to measure at* long after the particles have separated. * There is one theory of QM that removes the possibility of choice from the universe.
