Superdeterminism may have solved the quantum measurement problem
A local, realist, reductionist interpretation with no extra dimensions, universes, or solipsism.
Quantum entanglement is weird, but it is hard to explain why. It seems quite mundane why two particles that were once in contact might be correlated.
Yet, Einstein called entanglement “spooky action at a distance.” And many physicists insist that information is transmitted instantaneously between particles. This information tells one particle both what experiment was done and the result of the measurement at the other.
Measurement correlation hardly seems unusual since if you have a bag with a black ball and a red ball and you reach in, pull out a black ball, and your friend reaches in, you already know they must pull out a red ball. Likewise, if you fire the black ball towards your friend Alice in one direction at near the speed of light and the red one in the other direction towards your friend Bob at near the speed of light, and Alice sees a black ball speeding towards her; Bob must surely see a red ball.
It is easy to show the difference between colored balls and particles using mathematics. The case of the balls is called a classical mixture, while the case of the particle spins is an example of…
