I don’t know how much discussion has been on a topic like this already, but allow me to explain.

> The term "world-building" was first used in the Edinburgh Review in December 1820 and appeared in A.S. Eddington's Space Time and Gravitation: An Outline of the General Relativity Theory (1920) to describe the thinking out of hypothetical worlds with different physical laws.

Well, that’s *very* broad, and I must admit so is this site. Sure, the definition has evolved some, but It’s still very close to how it was back then.

This site probably holds the record for most generic stack exchange website ever created. As a result of this you can basically ask any question you want and probably get an answer. Which of course I have no issue with, it makes the site unique, but sometimes it seems like what is considered to actually be worldbuilding is poorly defined.

Now recently I’ve been looking into simulations attempting to approximate a universe, in a rough way. To give you a idea of the concept, here is a piece of software that reflects the idea fairly well. [TIMU by buddhaman.](https://itch.io/queue/c/2490769/games-to-try?game_id=545192)

Now that the context is set up, what actually is worldbuilding? Making a fantasy land filled with magic for a book certainly is. Creating a sci-fi dystopia for a movie is too. Designing the hazards for a post apocalyptic wasteland in a video game surely is. But what about creating the design of a universe simulator? It’s definitely a world in a sense, definitely not real, and definitely something that you are making. How far does worldbuilding go, at least for the purposes of asking a question on this site?
