The Cosmic Thunderbolt - Electric Universe and Plasma Physics
This is a very nice introduction to the Electric Universe and Plasma Physics
If you zoom into the image of Galaxy GCM31 you will see the birkeland currents not keeping the jets linear. They meander back and forth as in the cover photo... This was/is a problem that stopped David LaPoint from joining the EU-team.
Goto thunderbolts.info to study more, but David LaPoint makes a good point that galactic plasma tails/trails/streams ejected into a Birkeland intergalactic Currents would straighten out the tails, yet they are instead meandering as in the cover photo.
