Post History

## On topic for the community name only
The question could be assumed to be on topic for the ***name*** of this community: "Scientific Speculation". It is indeed a speculative question about science that hasn't been discovered yet, extrapolated from science that is still in the process of being tested.

## Likely off topic for the community purpose
Like many websites, the name does not fully describe the purpose. The top of the Q&A category states the purpose for this category:

> General Q&A about worldbuilding and other speculative developments that can be extrapolated from science.

This community is for people who are building a fictional world, and want to establish what would be realistic. For example, they may be making board games, computer games, screenplays, or novels.

The separate category "Rigorous Science" is still serving the same purpose, just with a stricter requirement for well founded science.

## Grey areas
Different people may ask the same question for different purposes, so there will always be grey areas where it is not clear if a question is on topic.

In this particular example, it is possible someone might want to ask about preventing sight deterioration in adults as part of their work on a novel set in the near future, but that does not appear to be the case here.

For any community it is difficult to define exactly what is on topic, so the scope is refined over time by discussion on Meta. Now that you've identified this example, anyone is free to make the case for it being on topic, or for more generally accepting scientific questions that are not related to building fictional worlds.

By discussion and voting the community will decide what should count as on topic. By the current guidance, the example appears to be off topic to me personally.

## Existing documentation
You can find guidance in the [Scientific Speculation help section](https://scientific-speculation.codidact.com/help), which in particular includes the [Frequently Asked Questions](https://scientific-speculation.codidact.com/help/faq). 

## New communities
If you'd like Codidact to have a new community where scientific questions in general are on topic, or a community for a specific branch of science, or anything else, you can propose it at [Codidact Proposals](https://proposals.codidact.com/).
