A “rabbit hole” is an expression used to describe a situation where someone starts exploring a topic and keeps going deeper and deeper into it, often discovering more related information than they expected and spending a lot of time on it. Here are some of them. If you have other interesting rabbit holes that are not on this iceberg, feel free to propose them to me ! Links for the entries are WIP (Due to the nature of some of the entries, I will not provide any links to them. All of them lead you to safe places on the internet, mostly Wikipedia or Youtube.) !!! Some of the entries, not all of them, came from other icebergs !!! Credits to: u/LJ_fin ; u/BrokenEnthusiasm ; Feldup ; Cnawak ; Obscuria ; VZION ; Nick Crowley
