# Theory The only single document with a general overview of Urbit is our ginormous [whitepaper](theory/whitepaper). The whitepaper has been described as "sort of like a PhD thesis, but maybe more like three PhD theses jammed into a single 40-page document." Like Everest, it's there. Some critics experience doubt that Urbit is actually a real thing. This is forgivable. Sometimes, visual evidence will correct these disturbed minds. See our 2015 demo [(part 1)](theory/part-i), [(part 2)](theory/part-ii), or our original [2013 demo](theory/old). But if the aliens could fake the moon landings, they could certainly fake Urbit.
