“There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.”

astrophysicist and winner, with Louis Néel of France, of the Nobel Prize for Physics in 1970 for his crucial contributions in founding plasma physics—the study of plasmas (ionized gases).In 1939 Alfvén printed his theory of magnetic storms and auroral displays in the atmosphere, which immensely influenced the modern theory of themagnetosphere (the area of Earth’s magnetic field). He revealed a extensively used mathematical approximation through which the advanced spiral movement of a charged particle in a magnetic field can also be simply calculated. Magnetohydrodynamics(MHD), the learn about of plasmas in magnetic fields, used to be generally pioneered through Alfvén, and his work has been acknowledged as basic to attempts to regulate nuclear fusion.Alfvén used to be an early supporter of “plasma cosmology,” an idea that challenges the big-bang model of the beginning of the universe. Those who support the theory of plasma cosmology dangle that the universe had no starting (and has no forseeable end) and that plasma—with its electrical and magnetic forces—has accomplished more to organize matter in the universe into star systems and different large observed structures than has the pressure of gravity. A lot of Alfvén’s early analysis used to be integrated in his Cosmical Electrodynamics (1950). He additionally wrote On the Origin of the Solar System (1954), Worlds-Antiworlds (1966), and Cosmic Plasma (1981).
