Anatomy of a Galaxy in Evolution
Poincaré, at the conclusion of the preface to his book, `Hypthéses Cosmogoniques', states "One fact that strikes everyone is the spiral shape of some nebulae; it is encountered much too often for us to believe that it is due to chance. It is easy to understand how incomplete any theory of cosmogony which ignores this fact must be. None of the theories accounts for it satisfactorily, and the explanation I myself once gave, in a kind of toy theory, is no better than the others. Consequently, we come up against a big question mark."
Galaxies consist of a variety of objects that have been categorized into classes: normal, barred, peculiar, Seyfert, active core, elliptical, radio, quasars, and so on. The answer to why these classes occur in the universe requires a valid description of the universe.
According to the renowned plasma physicist David Bohm, "the universe is an unending transformation in flux whose previous states we are not privileged to know." The universe is taken to be a transformation in flux, of infinite dimension and time, that, in the current plasma state necessarily leads to electrical currents and magnetic fields.
According to the Nobel lauereate Hannes Alfvén, "Space is filled with a network of currents which transfer energy and momentum over large or very large distances. The currents often pinch to filamentary or surface currents. The latter are likely to give space, as also interstellar and intergalactic space, a cellular structure."
The structure above is a cut of the plasma universe showing the filamentary currents produced by plasma in flux. Plasma tend to separate into regions according to temperature, density, magnetic field strength, chemical constituency, and other physical properties. Wherever these regions are in relative motion, they are coupled by electrical currents that they drive in each other. Like all electrical currents, the circuit paths are closed, sometimes over very great distances. Thus plasmas in relative motion in one part of the universe can produce prodigious amounts of electrical energy. This energy may be transferred over many billions of light years to burst suddenly from a very small and localized region representing the circuit load.
Electrical currents produce two other very important physical effects. Electrical currents produce magnetic fields and microwave radiation. If the electrons in the current flow have relativistic velocities and are in the presence of the magnetic fields, synchrotron radiation is produced. Concomittant with the generation of magnetic fields are electric fields.
