A few examples like:
With all of these questions I can see how it could be useful to use within a story, however there is no context of that story. No "I want the black hole to be destroyed so I can..." just the question of how physics works. Whilst these are often unsuitable for physics SE I feel that without the context of a story we are drifting away from that world building aspect of the site in these questions.
I'm not saying we shouldn't be asked or respond with physics-based answers, but there may be a way to shoe-horn the idea into the scenario the writer desires using plot and some hand-waving. If we don't know what the end goal is we can't say "Well, you can't destroy a black-hole but a work-around which achieves your end goal is..". Instead, if we're sticking to the physics of our universe, quite often the reasonable answers end up being summed up by "I'm sorry Dave, I'm afraid you can't do that."
I feel like these are unsatisfactory answers if the OP is a writer.
Should we be encouraging questions to include a little context of their story?
