Plasma Universe / Big Bang comparison

Plasma astrophysicists investigate a wide range of astrophysical phenomena. Many apply their expertise to some of the latest topics in astrophysics, such as the Standard Cosmology, black holes, active galaxies nuclei, neutron stars and dark matter.

Other plasma physicists such as Hannes Alfvén, and others, took a different view, which is compared in the table below.

Plasma UniverseBig Bang model
General approachEmpirical: Application of known laboratory physics onlyKnown physics and "new" physics
(Empirical and hypothetical)
Plasma description"Real" plasma:
Magnetic & electric description
MHD and non-MHD
(approximates a real plasma)
Ideal fluid MHD Magnetohydrodynamics
Dominant forceElectromagnetic for smaller charged particles,
gravity for larger ones. See Gravito-electrodynamics
Electric currents
"Birkeland currents"
Prevalent in all cosmic plasma
Atmosphere, Stellar, Interplanetary,
Interstellar, Intergalactic
Atmospheric Birkeland currents
Cosmic electric circuitsYes
All electric currents follow Kirchhoff's circuit laws
"Invisible" energy transferYes: via circuitsNo
Double layersPrevalentLimited
FilamentationPinched currents (Bennett pinch)Magnetic?
Particle beamsPrevalentPerhaps?
Galaxy formationInteracting Birkeland currents
Electromagnetic and gravity
Gravity and dark matter
Electric chemical separationYes: "Marklund convection"No
Star formationPlasma pinch aids accretionGravitational accretion disk
Synchrotron radiationElectric fieldsBlack holes, gravity
CosmologyPlasma cosmologyStandard cosmology
Big BangNot knownYes
Black holesNoYes
Pulsar"Magnetospheric transmission line system" (See pulsar)Neutron star
Neutron starsNoYes
Dark matterNoYes
Dark energyNoYes
Magnetic reconnectionPedagogic tool describing how magnetic field lines re-orientate,
but field lines do not break, nor cause phenomena
RedshiftIntrinsic contribution,
eg.: Plasma redshift, Wolf effect ?
No intrinsic redshift
  Cosmological redshift (inflation)  

Note: Items in red require ad hoc "new physics", ie, physics never seen before in the laboratory.
