Multiverse Science Fiction

“Jewelled, the multiverse spread around him, awash with life, rich with pulsating energy,” (Moorcock). Indeed, Multiverse Science Fiction is a rich playground for writers and is literally full of infinite possibilities.

So, what is a multiverse? The definition is tweaked by each writer, but generally speaking it a multiplicity of universes branching out from every moment in time, of which our universe is only one. This means that in addition to a multiplicity of universes there is also a multiplicity of selves—each of us would exist in each of the other universes, though we may be a bit different in each one. Prompts some identity questions, doesn't it?

The plot of a story within this sub-genre must inevitable come to transportation. A character in the story must find a way to interact with another universe. Characters may be able to control which universe they go to, or not. As characters explore other universes they may find only slight differences among the universes, or drastic differences like the very nature of the physical world. Travel devices are common—think the show Sliders, which has a handheld device that opens worm holes—but gates are even more common.

Other Features of Multiverse Science Fiction

  • Level of Real Science

    Low-Moderate. Physics has an interest in the idea of the multiverse, so science can be a real and integral part to a Multiverse story. Given our limited understanding and perception the science has to go beyond our current scientific understanding—but that's exactly what sci fi is supposed to do.

  • Level of Grand Ideas/Social Implications

    >High. The possibility of infinite universes and infinite selves leads to many many questions. The biggest question Multiverse Sci Fi has to tackle is that of our origin. The big bang theory is now just an event that helped our universe branch off from the greater multiverse—a multiverse to which we are still connected. The idea shakes the foundations of many worldviews.

  • Level of Characterization

    Variable. In Multiverse Sci Fi writers can take a traditional approach to character development, in which case all types of characters are possible. Or, writers can take a more postmodern approach to characterization—by presenting a more fragmented character, who has selves in multiple universes, each a little different than the next. This creates complex characterization and questions the very nature of identity.

  • Level of Plot Complexity

    High. When dealing with the possibility of infinite universes and infinite selves plots tend to get complicated. There will plenty of intertwining of story/character/themes and plenty of movement in a Multiverse story.

  • Level of Violence

    Variable. Multiverse Sci Fi has many variables and possibilities and the nature and level of any violence is part of these variables. Some stories involve detailed accounts of war and other stories are more spiritual and transcendent.

Related Science Fiction subgenres

  • Alternate and Parallel Worlds Science Fiction. Multiverse describes a “universe” that is made up of multiple alternate and/or parallel worlds that intersect. Multiverse is dependent on these two sub-genres, though it is distinct from them.

  • Time Travel Science Fiction. Time travel, especially the time travel paradox, assumes there is a multiverse—even if the story doesn't say so explicitly. The multiverse theory means that if you travel to the past and change something, the paradox is avoided by creating a new universe that branches off from yours.
