Plasma Physics Applied to Cosmology

FEB 01, 1971
It is time for a fresh approach to cosmical electrodynamics. Instead of searching for new laws of physics we should be trying to find out how to use the laws we already know.

Hannes Alfvén

The study of astrophysics in modern times should essentially involve the application of laboratory results to cosmical problems, with help from theoretical physics. In the realm of plasma physics, there appears to be no reason why known basic laws, formulated in the laboratory, should not hold just as well at the astrophysical and cosmological scale.
