Quasars are vast explosions, lasting millions of years, that occur in the centers of galaxies. They emit huge beams of energy, in only one direction at a time. (Smaller quasars are called “active galactic nuclei” or AGN.) While the most popular explanation for quasars is that they are giant black holes, their phenomena are duplicated on a much smaller scale by Herbig-Haro objects, which form as a stage in the birth of ordinary stars, so can’t involve black holes. In the 1980’s Eric Lerner, now LPP’s Chief Scientist, published papers using the plasmoids formed in a dense plasma focus as an electromagnetic model for quasars. In this model, the quasars formed as a result of current converging at the center of a galaxy, much as in the laboratory, plasmoid form as the currents in a plasma focus converge. The theory allowed Lerner to make quantitative prediction about the behavior of plasma focus devices that led to the development of the current focus fusion research.
