How does EU explain galactic rotation curves?

[rcglinsk]

I'll just cut to the chase. If each star is surrounded by a dual layer that would, as far as I know, shield everything inside from external magnetic forces, how does the galactic magnetic field exert a force on a star that constitutes the centripetal force which is apparent from rotation curves?

Assume you're referring to double layers, since we're not talking DVDs here, yes?

Double layers are layers of opposing charges (positives on one side, and negatives on the other, by and large) that tend to concentrate an electric field potential between them and lowers the overall electric field that would otherwise exist over a larger volume.

So, in a really bad example (I'm sure the numbers are far, far off), rather than having a medium strength field over a hundred meters between anode and cathode, there might be an extremely strong field within a half foot of the anode and within a half foot of the cathode, and then an extraordinarily weak electric field in between for the other 99 feet.

But, basically a particle would be very weakly accelerated for 99 feet, and then very strongly accelerated for the remaining half foot 'til it hits the anode or cathode... I hope I've not buggered that up too badly, as I'm still learning about double layers from scratch.

I don't know whether double layers interfere with magnetic fields as you suggest? Perhaps someone with more specific knowledge of double layers can answer that.

In any event, galaxy rotation curves seems to tentatively match up with PIC simulations of parallel currents through plasma (in cross section).

Part 2, I believe, shows a few rotational curve matchups and other comparison images.
