Superposition in Jewish Law
Question
Following up on the column about superposition in Jewish law, can the twilight period also be considered a kind of superposition?
Answer
That depends on how one understands the twilight period. There are views that it is both day and night (and not that there is a line between day and night that passes through the middle of twilight), and then perhaps one could compare it to superposition. But I think that here it is simply both this and that, and not superposition. In that column I pointed out that if there is no contradiction between the determinations, then there is no need to resort to superposition. If we understand that between day and night there is a segment composed of both of them, then there is no contradiction here.
For that matter, adding onto the Sabbath and the second day of a Jewish holiday are halakhic superposition.
Also worms that have not emerged from fruit are like Schrödinger's cat: they are worms, but not halakhically worms.
