erhole

Erhole is a term used primarily in speculative fiction and online discussions to denote a hypothetical opening in spacetime that connects distant places or moments. It is not a standard term in established physics, and its meaning varies by author and context.

In fiction, erholes are often depicted as alternatives to black holes or wormholes. They may be traversable and require exotic energy to stabilize, with properties that differ from conventional models. Some portrayals show erholes as naturally occurring features, others as gateways engineered by advanced civilizations. Commonly cited differences include the presence or absence of an event horizon, the need for stable containment, and the predictability of travel times.

Beyond fiction, the term is sometimes used metaphorically to describe gaps in a theory, data, or argument—an unknown or inaccessible region in a model.

Because erhole is a non-standard and context-dependent term, there is no single authoritative definition. Users should consult the source material for precise usage.
