The History of the Multiverse

Just came across the Wikia hosted DC Database Project, which has an incredibly detailed description of the Multiverse.

"The Multiverse consist(ed) of multiple versions of the universe existing in the same physical space, but separated from each other by their vibrational resonances.

The Original Multiverse was created as the result of interference in the Big Bang by Krona. It was destroyed by the Crisis on Infinite Earths.

An Interregnum Multiverse was created by Alexander Luthor during Infinite Crisis.
