I have to say, I just stumbled upon this and I love the idea of the site and the quality of its contributors.

I wanted to know if some kind of FAQ exists.  

Reason for this is I am interested in building a world/universe on my own and I lack a lot of common knowledge people who are into this genre already have.  

Therefore I am looking for some list of principles/FAQ etc. to get a better overview of what to consider while contructing ones world. I would want it to be a futuristic semi-sciene based universe, meaning the laws of science should apply but speculations like FTL will also be used.

I know that you can filter be frequently asked questions which is quite literally my answer to an FAQ, but I meant something more like a guide/wiki style
