Two Types of Antimatter in the Dynamic Cosmic Medium Model (DKMM)

This article develops the interpretation of antimatter within the Dynamic CosmicMedium Model (DKMM) and proposes that the term antimatter need not denote asingle physical phenomenon within this framework. Instead, a distinction isformulated here between two qualitatively different types of states that may bemerged under one name in ordinary description.The first type, designated as type A, corresponds to a complementary deficitexcitation of the medium relative to its local equilibrium state. It is not a negativemedium nor a separate negative substance, but a deficit deviation of the samepositive medium. This type naturally presents itself as an interpretation of smallpair-produced antiparticles. The second type, designated as type B, represents adeeper and structurally different case: truly oppositely organized matter, that is, adifferent stable nodal regime of the medium, not merely a deficit relative to theordinary state.The article shows that, upon contact with ordinary matter, both types could lead torelease of energy, but by different mechanisms and with different intensity ofpressure response of the surrounding medium. Whereas type A may be understoodas a local equalization of a complementary disturbance, type B may represent acollapse of two incompatible structural regimes of the medium. On this basis, aworking hypothesis of a critical amount of type B antimatter is further formulated,below which the reaction remains local, in the transition region may trigger a limitedcascade, and above it could in an extreme case pass into a self-sustaining avalancheregime.The aim of the text is not to claim that the existence of two types of antimatter hasbeen experimentally confirmed, but to offer a conceptual extension of DKMM thatmay refine the interpretation of antiparticles, energetic processes, and possibleextreme consequences of contact between different states of the medium.
