intrappolo

Intrappolo is a neologism used chiefly in speculative cosmology and science fiction to denote a localized region of spacetime in which gravitational trapping severely limits the exchange of information with the exterior. The term does not correspond to an established physical object and has no experimental verification.

Etymology and concept: The name is intended to evoke being 'inside a trapped loop' in spacetime. It is a fictional or theoretical construct rather than a defined physical entity in mainstream physics.

Theoretical framework: In hypothetical discussions, intrappolo regions are described using general relativity and concepts of trapped surfaces, horizons, and causal structure. Models explore how information, energy, and matter could evolve under strong gravitational effects and whether remnants could be recoverable or lost.

In fiction: In science fiction and popular media, Intrappolo is used as a setting name—an enigmatic zone, a research outpost, or a hidden city—often associated with mystery, memory, or the boundaries of knowledge.
