Paradigm transition in cosmic plasma physics

In situ measurements in the magnetospheres together with general advancement in plasma physics are now necessitating introduction of a number of effects that have been recently discovered or earlier neglected. Examples are: electric double layers (like in the lower magnetosphere); thin current layer (like in the magnetopause) giving space a cellular structure; current produced filaments (e.g., in prominences, solar corona and interstellar clouds). Further it is important to use the electric current (particle) description and to study the whole circuit in which the current flows. The pinch effect cannot be neglected as is now usually done. The critical velocity phenomenon is essential, for example for the band structure of solar system. Theory of dusty plasmas is important. The result is a change in so many theories in cosmic plasma physics that it is appropriate to speak of an introduction of a new paradigm. This should be based on empirical knowledge from magnetospheric and laboratory investigations. Its application to astrophysics in general, including cosmology, will necessarily lead to a revision of, e.g., the present theories of the formation of stars, planets and satellites. It is doubtful whether the big bang cosmology will survive. (Auth.)
