Suppose a Jewish text says something. Suppose this something relates to some factual reality. Suppose I wonder whether the something is actually true. Would it be on topic to ask about it on Mi Yodeya?
Let's take a simple example to illustrate this:
The Talmud (Berachot 35b) states:
וחמרא מי סעיד והא רבא הוה שתי חמרי כל מעלי יומא דפסחא כי היכי דנגרריה ללביה וניכול מצה טפי טובא גריר פורתא סעיד
But does wine sustain? Did not Raba use to drink wine on the eve of the Passover in order that he might get an appetite and eat much unleavened bread? — A large quantity gives an appetite, a small quantity sustains. (Soncino translation)
Upon reading this Talmudic passage I begin to wonder if it is in fact true that a little bit of wine fills you up but a lot of wine makes you hungry. Note that the question I would be asking is not seeking an interpretation of the Talmudic passage, nor is it asking for the Jewish view of anything. I don't want to know whether "there's a deeper meaning to this passage", or "nature has changed", or "the Talmud might have later rejected this idea", or anything of the sort. I would simply be looking for confirmation or denial of the alleged fact – is it true or false that a small quantity of wine fills you up while a large quantity of wine makes you hungry?
Ostensibly, the question itself has nothing to do with Judaism or Jewish life. However, it was generated from Judaism, and the answer to it may affect my understanding of one of Judaism's core texts. Additionally, it is perhaps reasonable to think that the question would be of interest to other members of Judaism, as they might have studied the same passage and had the same question. It is also perhaps reasonable to assume that "experts on Judaism" might be specifically qualified to answer this question since they may have had to address it themselves when studying the Talmud.
So, does that make it on-topic, or is it still off-topic because the question itself is not about Judaism or Jewish life in any way shape or form?
Obviously, I could edit the question somewhat to make it definitely on topic, but that's not what I am trying to raise here. I want to know if a question of that form would be on topic.
Additionally, you don't need to get hung up on this specific example. There can be other similar types of questions where the statement being fact-checked is a more practical statement or a less practical statement.
Also, you don't need to discuss whether the question itself is a good question (e.g. is it answered in the first Google result?). For the sake of this (Meta) question, assume that the (potential Mi Yodeya) question passes the basic standards to be a question on the Stack Exchange network in general.
