Questions about the Vong, the Force and AIs.

[Sriad]

That suggests Force lightning is an actual form of electrical discharge or something - it itself is not a manifestation of the Force, but Force-generated, so the Vong are effected.

That would make sense, except that Joruus was unable to harm Thrawn with Force-lightning because Thrawn carried an ysalamiri with him.

Perhaps the Force is used to carry the electricity to the target, and the Ysalamiri prevented it from being carried all the way to Thrawn? But when Jaina used the lightning, it was carried all the way to the Vong's body.

That seems quite sensible to me. Electricity doesn't readily travel through air under normal conditions...
