This article presents a combined review of modern scientific concepts of superluminal communication and their connection to the Infinite-Dimensional Multiverse Model (IDM). The first part examines works that create the physical foundation for IDM: Arkani-Hamed, Dimopoulos Greene et al. (2023) — proof of superluminal communication without causality violation; Dai Benakli (2026) — Kaluza-Klein tower as an information channel; Emparan, Suzuki Casimir (1948) — vacuum modulation mechanism; Planck Collaboration (2020) — potential navigation data. It is shown that IDM proposes for the first time a specific method for determining the direction to a neighboring universe through the anisotropy of fundamental constants and provides an engineering formulation of the communication system. The second part is devoted to alternative concepts: phase modulation in plasma (Lieu & Duan, 2017/2025), attempts to bypass the no-communication theorem through quantum entanglement (Cornwall, Herbert), the speculative ITC (Instantaneous Teleportation Cosmos) model by Jim E. B. (2026), which posits the existence of a "basal" reality where information is transmitted instantaneously, and tachyon concepts. It is shown that IDM is the most physically grounded geometric approach that does not violate known laws of physics, unlike speculative attempts to bypass quantum mechanics. A comparative table is provided and conclusions are formulated. Superluminal communication is an actively developing topic with a theoretical foundation and potential feasibility.
