Arp's discordant redshifts were dead in 1975 when it was realized a uniform distribution of galaxies in a volume created the 1/z distribution of angular separation. Arp and supporters always ignored this. Details described in Discordant Redshifts: A Post-Mortem. Support among professionals has been rapidly dying off, in every sense of the expression, leaving mostly nothing but 'fanboys'.
One of Electric Universe claims greatest problem is where the power comes from to drive the claimed currents (see Challenges for Electric Universe 'Theorists'...).
Claims that galaxies, or stars, are actually powered by giant electric currents have more problems than 'dark matter' because such currents emit microwaves. We don't detect these microwave streamers passing through stars or galaxies. For stars like the Sun, such currents create all kinds of severe problems for satellites and astronauts.
For more details, see the "Death by Electric Universe" series at: Challenges for Electric Universe 'Theorists'.
And the big question is where is the battery or generator that powers all this? Where does it get its power!?
