We can see that the community agrees that questions should show what you have tried, and I'm glad about this. However, this question asks for ways to model a situation that is never seen in everyday life. In this case "realism" is difficult to judge because the observer will have no way of knowing if the result is what would really be seen in such a setting.
From the question:
I'm looking for realism in order to discover unexpected effects, not just to pass as realistic to a casual observer. Obviously most observers (including me) won't know the effects to look for since they aren't familiar from everyday life, so I'm looking for "reasonably physically correct" rather than just "convincing".
Is this enough of a reason to justify making an exception to "show what you have tried"? Is there another way in which prior effort could be demonstrated, without knowledge of the correct outcome?
How should we deal with questions like this?
