Parallel Universes Or Other Dimensions In Science Fiction!

Parallel Universes are unually synonymous with ‘Other Dimension.’ The use is especially common in movies, television and comics, even less in modern science fiction prose. The idea of ​​a parallel world was first introduced in comics with the release of Flash # 123 “Flash of Two Worlds”. 

In written science fiction, “new dimension” refers more frequently and more precisely to additional coordinate axes beyond the three known spatial axes. By suggesting a journey along these additional axes, which are normally imperceptible, the traveler can reach worlds that are otherwise unreachable and invisible.

In 1884, Edwin A. Abbott wrote the seminal novel that explores this concept called Flatland: A Romance of Many Dimensions. 

In 1895, The Time Machine of HG Wells used time as an additional “dimension” in this sense, considering the four-dimensional model of classical physics and the interpretation of time as a dimension resembling the space in which humans can travel. Wells also used the concept of parallel universes as a result of time as the fourth dimension in stories such as The Wonderful Visit and Men Like Gods, an idea suggested by the astronomer Simon Newcomb, who spoke about the time universes and parallels; “Add a fourth dimension to the room, and there is room for an infinite number of universes side by side, as for an unlimited number of leaves when we stack them together.”


There are many instances where authors have explicitly created additional spatial dimensions for their characters to achieve parallel universes. In Doctor Who, the doctor accidentally enters a parallel universe when trying to repair the TARDIS console in Inferno.

Douglas Adams uses the idea of ​​probability in addition to the four classical dimensions of space and time as an additional axis, similar to the interpretation of quantum physics in many worlds in the last book in the series Hitchhiker’s Guide to the Galaxy, Mostly Harmless Model were to capture the continuity of space, time and probability. 

Robert A. Heinlein postulated in The Number of the Beast a six-dimensional universe. In addition to the three spatial dimensions, he invokes symmetry to add two new temporal dimensions so that there would be two groups of three. Like the fourth dimension of H. G. Wells’ Time Traveler, these extra dimensions can be traversed by people using the right equipment.
