In the 1930s, when astronomers began measuring the rotation of spiral galaxies, they discovered something apparently impossible. Stars at the outer edges of galaxies were moving far too fast for the amount of visible matter present. According to classical gravitational models, galaxies should have literally torn themselves apart. To preserve the standard framework, physics introduced Dark Matter, an invisible and still undetected component meant to provide the “missing mass.” Yet after nearly a century: no Dark Matter particle has ever been directly detected not at CERN not in underground detectors not in direct cosmological observations At the same time, modern observations started revealing something even more important: Galaxies do not behave like simple gravitational collections of isolated stars. They oscillate. They undulate. They exhibit coherent collective motions, including the recently observed “butterfly wobble” behavior of the This is where the NMSI framework introduces the concept of PON-G, the Galactic Plasma Oscillatory Network. In NMSI, galactic plasma is not a passive medium. It acts as a gigantic electromagnetic coupling layer linking stars, magnetic fields, and energetic fluxes into a coherent oscillatory structure. In other words, a galaxy behaves less like a cloud of independent objects and more like a coherent flexible membrane filled with stars. This changes the interpretation completely. Galactic rotation becomes a collective plasma and electromagnetic coherence effect. Density waves emerge naturally. Butterfly oscillations become expected membrane-like dynamics. Large-scale synchronized motions stop being anomalies. Even more important: PON-G itself possesses a substantial physical mass, estimated to represent roughly 15% of the total galactic mass. This is critical because the oscillatory motion of such an enormous plasma structure can generate colossal electromagnetic fields. The local magnetic intensity measured per square meter may appear relatively weak. But when integrated across the entire galactic surface and volume, the result becomes an enormous electromagnetic structure on cosmic scales. A true EM giant. This may explain why galaxies behave elastically, maintain coherent structures across enormous distances, and respond collectively to external perturbations. Within this interpretation, there is no need to invoke exotic invisible matter to “hold galaxies together.” The issue was not missing mass. The issue was treating galaxies as purely gravitational systems while ignoring large-scale plasma coherence and electromagnetic coupling. In NMSI, the Universe is not an inert gravitational machine. It is a coherent oscillatory network of plasma, fields, and informational fluxes. And Dark Matter may ultimately prove to be not a real substance, but the artifact of an incomplete physical interpretation For more info: https://t.co/kjY6BSJJHi #NMSI #DarkMatter #MilkyWay #Galaxy #PlasmaPhysics #Cosmology #Astrophysics #Electromagnetism #Space #Physics #JWST #Science #Universe #GalacticDynamics #PONG #PlasmaUniverse
