Ambiplasma

Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe This is contrary to the consensus by cosmologists and astrophysicists which strongly supports the theory that astronomical bodies and large-scale structures in the universe are mostly influenced by gravity, Einstein's theory of general relativity and quantum mechanics. These can be used to explain the origin, structure and evolution of the universe on cosmic scales.

Some theoretical concepts about plasma cosmology originated with Hannes Alfvén, who tentatively proposed the use of plasma scaling to extrapolate the results of laboratory experiments and plasma physics observations and scale them over many orders-of-magnitude up to the largest observable objects in the universe (See box.)

As of 2017^[update], the vast majority of researchers have openly reject plasma cosmology and Alfvén's plasma scaling because it does not match modern observations of astrophysical phenomena or accepted cosmological theory.

Also the term plasma universe is sometimes used as a synonym for plasma cosmology, as an alternative description of the plasma in the universe.

In the 1960s, the theory behind plasma cosmology was introduced by Alfvén, who won the 1970 Nobel Prize in Physics for his other (unrelated) work in magnetohydrodynamics (MHD),Oskar Klein and Carl-Gunne Fälthammar. In 1971, Klein extended early proposals and developed the "Alfvén-Klein model" of the universe, or metagalaxy, an earlier term to distinguish between the universe and the Milky Way galaxy. In this Alfvén-Klein cosmology, sometimes called Klein-Alfvén cosmology, the universe is made up of equal amounts of matter and antimatter with the boundaries between the regions of matter and antimatter being delineated by cosmic electromagnetic fields formed by double layers, thin regions comprising two parallel layers with opposite electrical charge. Interaction between these boundary regions would generate radiation, and this would form the plasma. Alfvén introduced the term ambiplasma for a plasma made up of matter and antimatter and the double layers are thus formed of ambiplasma. According to Alfvén, such an ambiplasma would be relatively long-lived as the component particles and antiparticles would be too hot and too low-density to annihilate each other rapidly. The double layers will act to repel clouds of opposite type, but combine clouds of the same type, creating ever-larger regions of matter and antimatter. The idea of ambiplasma was developed further into the forms of heavy ambiplasma (protons-antiprotons) and light ambiplasma (electrons-positrons).
