This document presents a global scientific-transition framework based on a unified reinterpretation of fundamental physics in which all measurable phenomena arise from a frictionless etheric medium governed by a scalar pressure field Ψ. The objective is to preserve the continuity of all existing scientific programs —laboratories, instruments, budgets, research lines, and academic careers— while redefining only the physical interpretation of the phenomena already observed. The paper provides a 12-month transition plan designed to reorient dark-matter laboratories, dark-energy programs, cosmic-expansion surveys, galactic-morphology projects, high-energy-physics facilities, and CMB missions without discarding any infrastructure, data, or methodology. It includes domain-specific analyses, case studies (DESI, LZ, CERN), institutional communication guidelines, academic-integration protocols, international coordination strategies, psychological-impact mitigation, and a long-term technological roadmap. The proposal maintains that no scientific investment is lost: every resource is repurposed toward more coherent objectives such as mapping ether-pressure gradients, refractive-index evolution n(t), Ψ-field vibrational modes, and large-scale pressure structures. The document establishes a constructive, disruption-free transition that strengthens global research while opening new technological avenues based on the dynamics of the etheric pressure field.
