Black Holes Are Doors: Horizons as Decoder Boundaries, Singularities as Phase Transitions, and Navigation Through Topological Thresholds

A black hole is understood in general relativity as a region from which nothing escapes. This paper proposes a reinterpretation: a black hole is not a trap but a topological threshold — a point on the coherence landscape V(K) where the gradient is so steep that one decoder ceases to function and another begins. The horizon is not a barrier in the code — it is the boundary of a specific decoder’s domain of validity. The singularity is not infinite density — it is a phase transition where the old minimum is destroyed and a new minimum forms. ER = EPR implies every black hole is a wormhole, every horizon a door. The information paradox dissolves: the barrier is in the decoder, not the code. The same structure operates at every scale: physical (gravitational collapse), cognitive (paradigm destruction), institutional (F → 0 collapse), civilizational (species boundary). The difference between transformation and destruction is coherence: K > K_crit through the transition means emergence; K < K_crit means destruction. Black holes are not endpoints. They are transitions. Part of the Spektre research corpus.
