A discovered "paradox" in the double slit experiment

Click For Summary
The discussion centers on a paradox arising from the double slit experiment when introducing two observers, one inside a box and one outside. When the observer inside (person 1) measures which slit an electron passes through, the interference pattern disappears for them, while the outside observer (person 2) expects to see an interference pattern due to their lack of knowledge about person 1's measurement. However, it is clarified that the act of measurement by person 1 alters the experimental setup, leading to the disappearance of the interference pattern regardless of person 2's knowledge. The conversation also touches on interpretations of quantum mechanics, including the measurement problem and superposition, suggesting that both observers will ultimately agree on the observed outcomes. The conclusion emphasizes that any measurement, regardless of the observer's knowledge, affects the system's behavior and the resulting patterns.

At this point, there is actually no answer to the measurement problem ('Schrodinger's Cat') in the many-worlds picture since the 'Einselecton' program that would allow for splitting of worlds does not work: http://arxiv.org/abs/1406.4126
Among other things, this means that 'Quantum Darwinism' does not work either as an explanation for the emergence of the macroscopic world.
