I am thinking of adding a new tag that might be helpful in Worldbuilding. One of the tags I am think of at the moment is multiverse.
For questions pertaining to or about the existence of multiple universes.
Multiverse theory discusses the possible existence of multiple parallel universes. This theory partially explains why the universe can support life, despite the very small probability of the universe would have all of the properties needed for life to form. Multiverse theory explains the Weak Anthropic Principle. If an infinite number of universes each have different properties, when intelligent life develops in one they will observe that their universe seems to posses a specific set of properties needed to support life. Multiverse provides a scientific explanation for creationism in religion.
I was looking at a post and thinking "I could add a few tags to this," but when I looked for those tags, I realized they didn't exist. Specifically, it was this post.
I am not wondering if it is possible to add these tags or how to add them, I have the rep to do so. What I am wondering is whether I should. Will adding this tag be helpful to other users? I have read the help section about tags, and it says:
As a general rule, you should avoid creating new tags if possible, and new users are not allowed to create new tags. Even if you have sufficient reputation, you should only create new tags when you feel you can make a strong case that your question covers a new topic that nobody else has asked about before on this site.
I don't this tag would be particularly novel, but I think they would help users search for questions about topics they like. For example, someone who is really interested in multiverse in particular could search for questions with that topic.
Should I create this tag, or would it just be more noise on the site? It would be great to hear what people's opinions are on this.
