I asked a question recently: Why was the tree burnt?
Part of this question is checking whether Cyclops' optic blasts produce heat. That's only part of the question because if they do, then that makes for a pretty trivial answer: the tree is burnt because the blast is hot.
The actual question, though, is "If not, why was the tree burning?".
Yet, this question has been closed as a duplicate of a question that has nothing to do with this specific instance of Cyclops hitting something with his blasts and having it light up. The only part of the answer to the "duplicate" that is even relevant is "Nor does it emit infrared radiation or heat of any kind". All that does is justify my question, not answer it.
Note: I'm perfectly happy to edit the question if someone has a specific suggestion.
