Chorisont

Chorisont is a term used in science fiction to describe a class of artificial spacetime boundaries that enable near-instantaneous travel or communication between distant regions. In many depictions, a chorisont is a developed technology or constructed gateway that warps or stabilizes a conduit through which matter and information can pass with minimal conventional propulsion. The field or gateway is typically described as requiring precise energy balance, phase coherence, and gravitational control; improper tuning can cause spacetime instability, radiation bursts, or temporal displacement.

In-universe explanations vary. Some authors treat chorisonts as surfaces or membranes that define a horizon-like boundary, while others present them as a network or lattice of interconnected conduits. The phenomenon is commonly associated with exotic matter, negative energy, or quantum-entangled pathways. Chorisonts are frequently used as plot devices for exploration, colonization, trade, or military conflict, and they raise questions about causality, responsibility, and the ethics of rapid interstellar movement.

Across works, chorisonts appear in contexts ranging from exploratory missions and frontier settlements to political treaties and regulatory regimes that govern access, safety standards, and ownership of routes. The term remains a flexible concept in fiction, often adapted to fit the science backdrop of a given universe.
