The Uncyclopedia universe is the horrifying alternate reality where everything ever written on Uncyclopedia is true and exists, including people's lives/biographies, historical events, culture and such. Since there is an infinite number of alternate realities out there, there is a 10^googolplex^googolplex^googolplex chance that a given universe may be exactly what Uncyclopedia describes. This is in contrast to our own reality, where almost anything non-fictional on Wikipedia is mostly true (with some exceptions) instead.
