Plasmas are strongly influenced by electro-magnetic forces. A laboratory simulation of two interacting electric "Birkeland" currents, models many characteristics of galaxy formation. The Electric Universe is based on the known properties of plasmas, in preference to unproven theoretical physics, and consequently does not require black holes, dark matter and dark energy, neutron stars and the Big Bang.
Is that Dr. Peratt’s galaxy simulation?
I must have seen that many years ago in “The Big Bang Never Happened” by Eric Lerner.
Lerner was working on an interesting plasma-focus device... wonder if he ever made something useful.
