Tesser is a term primarily used in the realm of science fiction and fantasy to refer to a hypothetical device or concept that enables dimensional travel or teleportation. The word is derived from the Latin word "tessera," meaning a small cube or tile used in mosaics, which symbolizes the idea of different dimensions or worlds being interconnected.
In various works of fiction, a tesser may be depicted as a physical object, such as a device or machine, that allows individuals to instantaneously move from one place to another, crossing spatial distances in a manner that defies conventional transportation methods. The concept of tesser often implies the ability to travel across different dimensions, parallel universes, or alternate realities.
The exact mechanics or nature of a tesser can vary depending on the storyline, whether it is accomplished through advanced technology, supernatural powers, or magical means. Some narratives depict tesser as a risky and unpredictable process, fraught with dangers or complications, while others present it as a convenient and reliable mode of transportation.
The term "tesser" has gained popularity through its inclusion in notable works of fiction, such as Madeleine L'Engle's "A Wrinkle in Time" series, where it is used to describe a method of folding space and time to travel instantaneously. It has since become a commonly recognized term within the lexicon of science fiction and fantasy enthusiasts, often used to describe any form of teleportation or dimensional travel.
