For the sake of animal lovers, I come up with a variant of Schrodinger's Cat experiment thus: a. in place of the poor cat is a Young's slits setup, with one translucent side of the box doubling as the screen, b. in place of the lethal injection is a switch, c. at a certain fixed time (say 5 minutes after setting up), either one of the slits, depending on the state of the above switch, will be closed. The interference pattern is viewed from outside with the box still closed. What can I expect after (c)? If I understand Schrodinger's argument correctly, there should be interference pattern because both slits are in a superimposed state of open and closed and that state has not been observed. Is that correct? Or is the switch counted as an observer and there is no superimposed state after all?
