Question

During Elul we learned, among other things, the Talmudic passage about “coming simultaneously” in tractate Gittin. I read an article on the topic that argued that the problem of cause and effect cannot be solved by a scriptural decree, because this is a logical problem, and even a scriptural decree is subject to the rules of logic. Is this really a logical problem? I remembered that in the past I read a story about a person who received from his future self instructions for building a time machine, and then went back and sent those same instructions to himself. In that story there is a clear problem of cause and effect (the knowledge arrived only because he was able to go back, and that was only because the knowledge arrived…), but there is no logical problem here. The story works perfectly well. Rather, there is a loop here created by the author’s scriptural decree, so to speak. Can one make the same claim in the Talmudic passage about “coming simultaneously”? That the situation in which the woman is divorced because her courtyard transfers ownership to her (since she is divorced) is not in itself a contradictory state, but only the “jump” to it is problematic, and that jump (like the loop in the story) can be created by force of a scriptural decree?
(I was also told that in the story about the time machine there is no case of “coming simultaneously,” even though there is a cause-and-effect problem.)
