What is a multiverse and what types of multiverse are there?

Posted by Harbinger451 on March 2, 2014

The 451 ePublishing Haus CategoryWe are starting a new section of the website entitled the Multi-Verse Digest – a guide to to the best known alternative histories and other worlds of fiction, folklore, film and games. In this quantum age of a proposed infinite multiverse each is just as likely as the next! Harbinger451 will be exploring them soon. As an introduction to the concept of multiverses we have devised a list of types of multiverse – which is presented here for your information. It might be handy for writers and RPG-ers of speculative fiction (Science Fiction, Fantasy or Horror) looking for ideas for, and rationals behind, their invented universe or world setting.

The Multi-Verse Digest

In its broadest sense a multiverse (or meta-universe) is a collection of multiple universes, any number of which could be very similar to or very different from our own and each other. Many types of multiverse (and universes within them) have been theorised and none, some or all could exist simultaneously either together or apart. Here is a list of the basic types of multiverse that could exist… maybe.

The Cyclic or ‘Yo-yo’ Multiverse:
Our universe is one in a potentially infinite series of expanding and contracting universes that each end in a big-crunch before spawning the next with another big-bang. Every big-bang could reincarnate the universe in a slightly or even drastically different form.

The Wider Cosmological or ‘Infinite’ Multiverse:
Our universe is everything within the cosmological horizon… but what about beyond that horizon, are there a potentially infinite number of other universes out there in the great unknown void beyond our observable universe? Possibly… in fact, probably. When dealing with an infinity almost anything is possible and, to varying degrees, probable. So a vast and massively varied amount of other universes almost HAS to be out there.

The Quantum Split or ‘Spooky’ Multiverse:
The basic building blocks of our universe, the sub-atomic quanta, can be observed in a range of possible manifestations – each with a different probability or likelihood of appearing. What if each of these possible observations correspond to a different manifest universe – running parallel or parallax to ours on weirdly different, strange sounding, M-theory dimensions, strings or branes. At the quantum level all matter and energy may be linked, bound or entangled through time, space or extra dimensions with their counter-part quantile manifestations. Some or all quanta may exist in multiple places, times or dimensions at once. Many theorist’s use these apparent spooky properties of quanta to extrapolate wormholes and the potential for gateways or portals to another universal place, time, or even parallel world.

The Time-streams or ‘What if?’ Multiverse:
This extrapolation of the Quantum Split Multiverse stipulates that every random event has many possible outcomes and connotations – each with a different probability. A die throw has six possible outcomes, each leading to a slightly different but equally possible future. What if all those possible futures play out in different branching time-lines – each equivalent to a whole parallel universe ultimately leading back in time to the same initial causal event – whether its a Big-Bang or not?

The Dark or ‘Mysterious’ Multiverse:
The observable universe appears to be lacking a great deal when it comes to matter and energy. Where is it and what is it doing? We only know of (can see) about 5% of the matter and energy that should be in our universe. The rest we have labelled (for want of better terms) Dark Matter (27%) and Dark Energy (68%). What if this hidden unknown is beyond our normal perception, it occupies the same space or void but is on different continuum or continua, or has the same continuum but occupies a different space or void. These would not so much be different universes but would be quantum flip, dark or just other-world versions or slants of ours.

The Virtual or ‘Matrix’ Multiverse:
The computer simulated virtual worlds we can create are getting more and more advanced. Eventually we will be able to virtually simulate a world that is, for all intents and purposes, as convincing and ‘real’ as our own actually ‘real’ one. There could be multiple digital copies of these virtual worlds and in some they could create virtual worlds of there own as we have. This of course begs the question – how do you know if the ‘real’ world you are in now IS the ‘real’ world and not just one of many created by a Cosmic Programmer trying out different scenarios? Also – it rears the soul-destroying prospect of being in a virtual simulation within a virtual simulation… within a virtual simulation… and on and on ad-infinitum.

The Mathematical or ‘Ultimate’ Multiverse:
Mathematical possibility and probability provides an ultimate multiverse that contains every mathematically possible universe made manifest according to different laws of physics, varying constants and differing initial conditions. The rational behind this theory is – if something is mathematically possible it must exist… somewhere. If it can exist – it will… especially in an infinite multiverse.

The Speculative or ‘Fictional’ Multiverse:
Many gifted story tellers have created believable fantasy worlds as the imaginative stage on which their tales are dramatised. Any of them could be real in an infinite multiverse of possibilities. There could be a universe where those fictitious events took place. There could be a universe where H. P. Lovecraft’s Cthulhu Mythos is real, there could be one where Game of Thrones is actually happening and there could be one where the Galactic Empire relies on the control of a very rare spice from an obscure desert planet called Dune.

There could be universes out there where any form of magic system is real, or where the Force from Star Wars is real, or really Gothic ones where ghosts, werewolves and zombies roam among us and the vampiric Count Dracula is an actual historical character.

As counter-intuitive as it may seem for a relatively scientific speculation on the nature of everything – in an infinite multiverse there could be universes where any connotation of the religious or philosophical beliefs that we have invented while on this planet Earth IS real and true… for me – that is the most terrifying possibility of all.

What is a universe and what types of universe are there? Coming soon!
