I wrote an answer to question Who wrote about an energy free space elevator?.
The question is asking for scientific writers - which may indicate science-fiction writer using real science, or actual scientists - who would have considered the energy free space elevator. This is actually a triviality from a scientific point of view, based on a principle that was probably known even to engineers in the middle ages, possibly earlier.
Thus I suggested the names of scientists who had contributed the idea. They clearly were scientific writers, as requested in the question.
The answer was deleted on the basis that they are not science fiction writers, which is not what is being asked.
I actually checked the wording of the question before answering, as the answer represented some real work on my part, which I thought might be useful to science-fiction readers. It could also be useful to some authors who do write nonsense on that topic.
The site is about science fiction, but there is no constraint that matters relevant to science fiction should exclude real science, or real scientists.
But I did not get a chance to answer the moderator criticism, which seems unfounded, given the actual wording of the question, which is not the wording the moderator seems to be asserting.
