crossdomes

Crossdomes are a concept originating in early 21st-century speculative fiction, often appearing in works exploring themes of parallel universes, alternate realities, or dimensional travel. The term itself implies a crossing or merging of distinct realities, often referred to as "domes" or "universes." This crossing might be a deliberate act of travel by individuals or entities, or it could be a more chaotic and unintentional bleeding of one reality into another. The nature of these "domes" can vary widely, from near-identical parallel Earths to vastly different planes of existence with fundamentally altered laws of physics. Common narrative elements associated with crossdomes include characters encountering alternate versions of themselves, facing paradoxes created by interdimensional interference, or navigating worlds where history has taken dramatically different turns. The technology or method by which these crossings occur is also a frequent plot device, ranging from advanced scientific apparatus to mystical or innate abilities. The consequences of crossdome events are typically significant, often posing existential threats to one or more realities involved, or leading to profound philosophical questions about identity, destiny, and the nature of existence itself.
