You may be refering to 1970 Nobel Prize in Physics
winner Hannes Alfvén
'. He is usually regarded as the father of this branch of plasma physics
Here's a short biography: Hannes Alfven (1908-1995)
In his own words from ''Electricity in Space
…"there is one great branch of physics which up to now has told us little or nothing about astronomy. That branch, is electricity. It is rather astonishing that this phenomenon, which has been so exhaustively studied on the earth, has been of so little help in the celestial sphere. Electricity has illuminated our cities but has shed no light on stellar phenomena; it has linked the earth with a dense net, of communications but has given no information about the universe around us.
Certainly we have seen plenty of evidence of electrical phenomena out in space. Within the last few decades we have discovered several important electrical effects in the heavens: strong stellar magnetic fields such as could only be caused by large electric currents, radio waves emanating from the sun and from many star systems, and the energetic cosmic rays, which are electrically charged particles accelerated to tremendous speeds.
These phenomena, however, are still very mysterious."…
"We know that interstellar space is not absolutely void. Although the matter in it is very thin, certainly not more than an average of one atom per cubic centimeter, in the vastness of the universe it adds up to an enormous amount of material. In at least some regions the interstellar matter is ionized, so that it is a good electrical conductor. Furthermore, there are good arguments for assuming that a weak magnetic field (some millions of a gauss) pervades all of space. It is likely, therefore, that magnetohydrodynamic waves roam ceaselessly througlr space, generating weak but very extensive electric fields, especially near the stars."…
I understand that his theories lead him to develop a quite unique cosmological vision.
