Earth
From Jenny Everywhere Wiki
A version of the planet Earth existed in one universe.
History and Description
The specifics of this version of Earth are unknown, although it was definitely populated by humans. Space travel was commonplace among the residents of this Earth, and a transport vessel would often carry people between Earth and its Moon, upon which the Lunar College of Selene had been established by earthlings, specifically those of the organization NASA.
Young geniuses of the planet were sent to the Lunar College, however, this was secretly part of a plan to stifle their intelligence, presumably to prevent some sort of uprising, suggesting a rather dystopian society. Nevertheless, IMAX documentaries are known to have existed there. (COMIC: Bacterial Lunarversity)
