# Is a question about whether something is possible on topic?

Is a question that asks whether something is possible within the laws of physics on-topic here?

(Very vague) Example: assuming any level of technology, can you do this within the laws of physics, or would some law(s) of physics prevent it?

Would such a question be on-topic here (with more details of course)?

If the question is asking if something is possible in the context of trying to better understand a specific physics concept, then I would say it is on topic for PSE.$$^*$$
$$^*$$ Of course, the question also needs to follow other site policies, be understandable, be focused, etc.
