Travel Along the Chain of Universes Along the w-Axis: From A₁ to A₅

This article presents a technical-fictional prototype of travel along the chain of neighboring universes $A_{1,1} \to A_{1,2} \to \ldots \to A_{1,5}$ based on the Infinite-Dimensional Multiverse Model (IDM). The text is a strict extrapolation of IDM postulates and supplements the prognostic article in the series. The key paradox is substantiated: the distance to a neighboring universe is undefined in three-dimensional space, making conventional "flight" impossible. The only means of travel is a quantum breakthrough between branes, requiring Planckian energy ($\sim 10^{19}$ GeV) and generators of planetary or stellar size. A step-by-step procedure is described in detail: identification of the $w_1$ axis, measurement of interaction intensities, breakthrough creation, stabilization, and navigation. The journey consists of a series of jumps between branes, not motion in the conventional sense — the ship remains stationary until the breakthrough. Possible universe types are classified by "hospitality": from habitable (constant deviations $\sim 10^{-3}-10^{-2}$) to sterile, vacuum-unstable, and singular. Specific scenarios of constant values and expected conditions are provided for $A_{1,1}\ldots A_{1,5}$. Demarcation from related concepts is carried out: academic brane models (Braneworld Hyperdrive, Green, Kabat et al.), science fiction (Baxter, Stewart), and Everettian branches (many-worlds interpretation). It is shown that the proposed mechanism (physical movement between branes via breakthrough) has no direct analogues.
