We have a few of question on the site that are purely hypothetical, more like thought experiments. I don't want to pick on anyone specifically, but I'll add some examples to make clear what kind of questions I mean:
- Would a plant need light if the chemicals gained by photosynthesis were given through the roots or as a foliar spray?
- Could an organism theoretically produce a metamaterial-like structure? [closed]
- If I put a cup over a spider, and leave it there for a day, will the spider survive?
Should these question be on-topic here? Where do we draw a line here?
