This article analyses the firewall paradox (wall‑of‑fire paradox, AMPS) — one of the most discussed challenges to modern quantum gravity. The paradox arises from an apparent contradiction between three postulates: the unitarity of quantum mechanics, the semiclassical description of Hawking radiation, and Einstein’s equivalence principle. Proponents of “informational language” argue that to save information, one must abandon the equivalence principle and accept the existence of a high‑energy “firewall” at the event horizon of a collapsar. It is shown that the firewall paradox is a problem of “informational language” , not a physical contradiction. The paradox is rooted in the conflation of the three senses of “information” (configuration, observer’s knowledge, pseudosubstance) introduced in Article 1. When reformulated in physical language (configuration, quantum correlations, unitary evolution), the need for a “firewall” disappears. Monogamy of entanglement is a property of quantum correlations, not an “informational principle”. The change in correlation structure after Page time is a technical problem, not a fundamental contradiction. Alternative approaches (Susskind’s complementarity) that do not require a firewall are considered. Responses to possible objections are given. The reformulation preserves the equivalence principle, eliminates the pseudo‑paradox, and turns the problem into a technical description of quantum correlations. The article is the seventh in the series “Reformulating Key Concepts of Physics Without Informational Language”. Keywords: firewall paradox, wall of fire, AMPS, collapsar, information, quantum correlations, monogamy of entanglement.
