alterworlds

An alterworld is a hypothetical concept within speculative fiction, referring to a parallel universe or dimension that exists alongside our own reality. Unlike simple alternate realities, which might differ by a single historical event or minor detail, alterworlds are often described as possessing fundamentally different physical laws, dimensions, or even forms of existence. They are not merely variations of our world but entirely separate and distinct planes of reality.

The idea of alterworlds allows for exploration of diverse and imaginative settings, free from the constraints of known scientific principles. Authors and creators use alterworlds to introduce fantastical creatures, unique magical systems, or societies that have evolved along vastly different paths. The concept often serves as a narrative device for characters to travel between these worlds, leading to themes of discovery, conflict, or the search for belonging.

While rooted in science fiction and fantasy, the concept of alterworlds can also touch upon philosophical ideas about the nature of reality and the possibility of multiple universes. The specific characteristics and accessibility of alterworlds vary greatly depending on the fictional work, ranging from realms that can be easily accessed to those that remain largely inaccessible or even unknown.
