A Time Decay Vacuum is a New Era of Space Science with Reference to Magnetohydrodynamic Flows

A controlled thermonuclear fusion reaction of the Sun is the heart of the space craft propulsion system. A band of ultraviolet radiation and X-ray emission of shorter wave length permeated by a magnetic mirror in the presence of a radiofrequency accelerator with the Sun at the resonant level is to produce hydrogen fusion laser due to a driving force to act as a laser fusion thruster. A superfluid helium (4He2) of burning with the Sun is a fifth state of matter. A higher state of matter is confined to a typical helical line which corresponds to the existence of outer universe.
