The Electromagnetic Spectrum

For millennia man has been privileged to observe the universe only in the visible. Thus, in the development of astronomy and astrophysics, what could be seen in a very narrow region, approximately 4000-7000 Angstroms, came to dominate the interpretation of the observed data. While radio astronomy became important in the 1950's, it had only minimal impact on already well-developed world models and in fact, some of the data could be claimed to support existing models.

Not until the 1980's did much of the electromagnetic spectrum become known (or was even suspected to exist). With the exception of plant life, sight is one of the most important senses to life on earth and, neglecting phenomena such as lightning, the aurora, and the stars, favors the existence of the first three states of matter as found on the surface of earth: solids, liquids, and gases. Thus, since solids, liquids, and gases are the most identifiable forms of matter on earth, their transference to other `masses' in the universe, such as the planets and their satellites, but also to the stars, seemed reasonable in the development of early astronomical theories.

The dissipation of the source energy from evolving or moving plasma in localized regions can then lead to pinches and condense states. Where double layers form in the pinches, strong electric fields can accelerate the charged particles to high energies, including gamma ray energies {Alfvén, 1981}. These should then display the characteristics of relativistic charged particle beams in laboratory surroundings, for example, the production of microwaves, synchrotron radiation, and nonlinear behavior such as periodicities and `flickering.'
