Wikenigma is a unique wiki-based resource specifically dedicated to documenting fundamental gaps in human knowledge.
Listing scientific and academic questions to which no-one, anywhere, has yet been able to provide a definitive answer. [ 1010 so far ]
That’s to say, a compendium of so-called ‘Known Unknowns’.
I’ve enjoyed browsing around on this site before. Too often, I look for mysteries online and it’s just ARGs and true crime. This is the mystery I’m looking for.
