This document presents Anti-Vacuum Theory, a conceptual theoretical framework proposing that gravity emerges from deviations of a cosmic quantum vacuum field from its equilibrium state. The theory introduces the concept of a neutral vacuum equilibrium state, denoted by the symbol ∅, representing a balanced configuration of the cosmic field. Matter and energetic astrophysical processes are hypothesized to disturb this equilibrium, generating local vacuum imbalances. Under extreme conditions, such as stellar collapse and supernova events, the field may undergo a critical phase transition into a new state referred to as the Anti-Vacuum. Within this framework, black holes are interpreted as stable Anti-Vacuum structures characterized by large quantum pressure differentials relative to their surroundings. Gravity is therefore treated as an emergent phenomenon arising from the dynamic tendency of the cosmic field to restore equilibrium rather than as a fundamental interaction. This work is intended as a conceptual and exploratory theoretical proposal and should not be considered an experimentally validated physical theory.
