I'm currently playing a dark side using Sage, and think that the way One with the Universe is currently written doesn't make a lot of sense. As it stands, you get one white pip if you roll successes and no threats, and a black pip if you roll both successes and threats. This works great for a light side user, but for a dark sider not so much.
One would think that becoming better at Astrogation would prove beneficial, but that's not always the case for the darksider, since that would be increasing his chances to get white pips rather than black pips.
I'd say its pretty reasonable to make a house rule that, in the case of darksiders, the color of the pips is inverted in the use of this power (generating black pips with successes and no threats, and white pips with successes and threats), but is there any way to interpret this as such with RAW?
