=====Plasma Cosmology - Plasma Cosmology Viewpoint=====
===Lede===
Plasma cosmology represents an alternative framework to the standard model of cosmology by prioritizing the roles that electromagnetic forces and plasma physics play in the formation and evolution of cosmic structures. This perspective challenges some fundamental components of the Big Bang theory, such as the notion of cosmic expansion. By focusing on electromagnetism and plasma interactions, proponents argue for a different understanding of astronomical phenomena.

===Current State===
The theoretical foundation of plasma cosmology is built upon principles from plasma physics and electromagnetism, offering unique insights into astrophysical processes. This field proposes that electromagnetic forces significantly influence large-scale cosmic phenomena. Research in plasma cosmology often focuses on areas where these effects are pronounced, such as the behavior of astrophysical jets and galaxy formation. Although it is not a mainstream model within astronomical observatories, research continues at smaller institutions or through collaborative efforts, leveraging computational models to simulate plasma interactions that may elucidate the structure of cosmic phenomena. For an in-depth look into its development, readers can refer to [[plasma-cosmology-history]].

===Notable Proponents===
Hannes Alfvén, the Swedish physicist and Nobel laureate, laid much of the theoretical groundwork for plasma cosmology through his foundational work in plasma physics. Alfvén identified Birkeland currents — filamentary electrical currents flowing through magnetized plasma — as a mechanism capable of structuring matter on cosmic scales, and argued that electromagnetic forces had been systematically underestimated in astrophysical modeling. His work on magnetohydrodynamics provided the mathematical framework that later plasma cosmology researchers would build upon.

Anthony Peratt extended Alfvén's work through large-scale computational simulations of plasma interactions. Peratt's simulations demonstrated that z-pinch dynamics — the magnetic self-compression of current-carrying plasma filaments — could reproduce galactic morphologies resembling observed spiral and elliptical galaxies without invoking gravitational collapse or dark matter. He argued that scaling arguments derived from laboratory plasma experiments could be applied to cosmic dimensions, and his numerical work sought to show that electromagnetic forces operating over intergalactic distances could account for the filamentary large-scale structure observed in galaxy surveys.

===Viewpoints===
Proponents of plasma cosmology argue that electromagnetic processes — specifically Birkeland currents and z-pinch dynamics — are capable of explaining both galactic and intergalactic structures without resorting to concepts like dark matter or cosmic inflation. Advocates hold that the filamentary large-scale structure of the universe, in which galaxy clusters are arranged along thread-like formations separated by voids, reflects the morphology of current-carrying plasma structures observed in laboratory settings and predicted by electromagnetic scaling. This viewpoint is detailed on [[plasma-cosmology-explaining-structures-without-dark-matter-viewpoint]]. Critics, however, contend that there is a lack of empirical support for plasma cosmology when compared with the Lambda Cold Dark Matter model, which is widely accepted in the scientific community ([[plasma-cosmology-lambda-cdm-skeptics-viewpoint]]). Additionally, some advocates suggest that plasma cosmology offers a more unified perspective on physical laws by integrating electromagnetism with gravity. They point to phenomena such as Birkeland currents threading galactic filaments, z-pinch compression as a mechanism for star and galaxy formation, and the correspondence between laboratory plasma morphologies and observed cosmic structures as evidence that a single electromagnetic framework can account for phenomena that mainstream models attribute to multiple separate mechanisms ([[plasma-unified-physics-viewpoint]]).

===Controversies===
There is an ongoing debate regarding the ability of plasma cosmology to adequately explain observational data, including redshifts and cosmic microwave background radiation ([[plasma-cosmology-adequacy-of-explanations-controversy]]). Critics also question the scientific validity of plasma cosmology's methodologies when compared with those used in mainstream cosmological models ([[plasma-cosmology-scientific-methodologies-controversy]]). Another point of contention is the interpretation of redshifts as results of electromagnetic forces rather than cosmic expansion ([[plasma-cosmology-redshift-interpretation-controversy]]). Furthermore, discussions have arisen about potential biases within peer review processes in the broader astrophysics community ([[plasma-cosmology-peer-review-bias-controversy]]). Lastly, there are disputes concerning whether laboratory plasma phenomena can be effectively scaled to cosmic dimensions ([[plasma-cosmology-scaling-plasma-to-cosmic-scales-controversy]]).
