The term multiverse has many nicknames including but not limited to quantum universes, alternate universes, alternate realities etc. But, what is the multiverse? If one was to look up the meaning of the word, the definition that is provided in the Oxford Dictionary states “a hypothetical space or realm consisting of a number of universes, of which our own universe is only one”1. The use of the term multiverse or its other moniker parallel universe, has been used in cosmology, physics, and philosophy to perhaps more prominently in science-fiction literature and movies for decades. Ever since Edwin Hubble discovered that the universe is expanding in the 1920s, there have been questions regarding the possibility of there being more than one universe. However, there has been no evidence to support the existence of multiverse. Interestingly, despite us humans being inherently logical beings, we still entertain the notion of multiverse which someone has yet to discover or observe. Why should the notion of having more than one universe than our own be any more valid than other scientific idiosyncrasies? As it turns out, the existence of parallel universes was not readily acceptable to physicists either. However, Eternal Inflations theory, String theory; which predicts the possibility of the existence of more than trillions of universes within multiverse as well as there being more than three dimensions that us humans perceive, echo the existence of multiverse which caused physicists to pay more attention to this notion.
An American philosopher named William James used the term “multiverse”, to explain a theoretical, unseen but moral and just universe different from ours, in his essay “Is Life Worth Living?” published in 1895 2. However since then, physicists have used the term to refer to the hypothetical existence of actual universe other than our own. Out of them, a
