The only thing like it in fiction is the Conjunction of the Million Spheres in Moorcock's multiverse: an event, that occurs once in an eternity, in which travel between the "million spheres" or "fifteen planes" is momentarily possible. At other times, such travel requires powerful magical artifacts.
Real-life multiverse cosmology considers the possibility of collisions between universes. Such collisions are likened to collisions between high-tension wires, only on a scale that releases a Big Bang instead of a shower of sparks. Nobody knows whether any form of multiverse cosmology can ever be proven.
