Low-frequency wave excitation by weak nonlinear interaction of two high-frequency pump waves: part II-experiments
This paper presents an experimental study of the characteristics of the LF wave excited in a hot magnetized plasma column by weak nonlinear interaction of two HF pump waves. These experimental features are systematically compared with theoretical ones which have been established in a previous theoretical paper.
Are the Galaxies Really Receding
Sixty years of competing speculation and theory have failed to establish conclusively whether the Big Bang expansion concept is valid. Three methods to resolve the continuing impasse are discussed. First, it can be shown that two initial assumptions of the theory directly contradict each other, producing inconsistent and unacceptable results. Secondly, based on well established facts and assumptions, an organized, disciplined proof shows that observed conditions in a hypothetical expansion would be contrary to those which are now actually observed. Finally, a new method is presented to directly determine whether galaxies are receding or not based on rotation velocity and independent of the redshift. If no recession is found, there can be no universal expansion.
