Universe A (The Secret Origin of Jenny Everywhere)
According to Jenny Everywhere: Secret Origins, a comic book with the actual Jenny should be taken with a grain of salt, the universe in which Jenny Everywhere was originally born existed at the Edge of the Multiverse until it was destroyed.
Cosmology
According to the comic, this universe was home to an Earth that was, in some significant absolute sense, the oldest multiversal counterpart of the planet. There, science was highly advanced, to the point of a utopia. There appeared to be little in the way of space travel, however, though ways to observe the cosmos from Earth did exist.

History
According to Jenny Everywhere: Secret Origins, the universe was attacked by a Living Black Hole, an intelligent force of destruction which consumed planets and stars. It rampaged through the universe over a period of several months, getting ever closer to Earth. One eminent scientist discovered the reason that the stars had been going out, but his warnings were dismissed as "monster stories" by the ruling authorities of the planet.
In desperation, the Professor and his wife built the Pod, a device capable of withstanding the destruction of the universe. It only had room for a small child: their baby daughter, Jenny. They placed Jenny in the Pod just as the Black Hole arrived, tearing the skies apart, but the machine worked, saving Jenny. However, it had the unintended side-effect of sending her everywhere in the Multiverse at once, splintering her to infinity; thus, Jenny Everywhere was born. (COMIC: My Bloody Valentine)
In contradiction to Secret Origins, however, Jenny Everywhere once returned to her mother's house "for the first time in centuries", showing that Jenny's original homeworld still existed. She also recalled growing up with her mother until she was at least six years old, casting further doubts on the reliability of the comic book. (PROSE: Memories of Nowhere)
