Big Bang (Original Multiverse)

Big Bang is an event that created the Original Multiverse.

History
In the beginning, there was only one, A single black infinitude. Then the infinitude found release and "exploded" in a big bang, marking the creation of everything in existence; filling a multiverse. When Barry Allen meets the Speed Force speaking as Joe West, it claims that it itself was present when the first subatomic particle sprang forth from the Big Bang to form reality; and will do so even when the universe decays.
