The evidence displayed here is fantastic and my only comment is that a common question asked is "Where is the power source?". For me it is fairly obvious that plasma in space provides such a good conductor of electricity that we haved a lossless sytem, continuously circulating current through invisible Birkeland current filaments, tubes, etc. An initial 'spark' was all that is needed to provide energy which cannot be destroyed.
Each galactic system concentrates and distributes its energy supply through component parts, with no losses.
Does anyone disagree?
