The Map of the Multiverse

Countdown #39 offered some mechanical information about the new multiverse: A Source Wall surrounds each universe and there is Anti-Life between walls. The Bleed is also between universes, but it "is moving" (the Bleed allows for quick transport between universes). Time is not equal among them. This sounds complex, and you'd be right to wonder if Batman's large wager on partybets carries over into the other universes, but I think we know there are bigger issues at hand—Marvel Zombies is a great example!

Before they were destroyed, the Monitors lived in a nexus that existed "everywhere at once"; they could not see into the Bleed. There is also a stray area between universes called Limbo, the home of forgotten people.

Various things allow transport across universes: Contol of the Anti-Life Equation; the Speed Force and Cosmic Treadmill; quantum mechanics; the lantern belonging to Earth-9's (Tangent) Green Lantern.

Recently, the sentient Source supposedly recombined with it's opposite half, the Anti-Life. At this time, Darkseid was also killed. But since Darkseid soon returned, and controlled the Anti-Life as a distinct force, it is probable that the status quo is once again a separate Source and Anti-Life.

Earth-0 Ray decided to take up Ray-51's life, which included a happy marriage to Jean Loring, and a science project that would allow him to travel across the multiverse. All life on this world was destroyed when Superboy Prime breached Monarch's containment suit (Countdown #13). Afterwards, its monitor, Nix Uotan, remade humanity. But it was doomed again, as the site of the "Great Disaster." Brother Eye came to Earth-51 and unleashed the Morticoccus virus (also spread by Karate Kid). The only human survivors were Buddy Blank and his grandson, the "last boy on Earth," who becomes Kamandi. This is the setting for DC's 1970s titles OMAC and Kamandi.
