OOC: No I'm not trying to argue from an OOC standpoint that it is genetic, just from the IC Veridian view they'd rather lay it to something genetic than saying its some mystical power force embedded within the fabric of everything. They will believe they can explain powers like force-push, moving objects, etc. as advanced telekinetic powers vs saying its someone's ability to "use the force." Just as they would explain Jesus Christ as being some advance form of alien life than accepting the notion that he's the son of God, for example.
I have no problem with not using the medichlorians as it doesn't hurt the idea of the RP I have in mind. I just want to make sure it won't completely screw over what you've already established through your own RPing of Jedi and Sith if the Veridians, through experimentation, find some more scientific way to explain the force for themselves. Again, think of it as completely non-canon and we can even go as far as saying the Veridians have it completely wrong, but for them they'll think they've got it all figured out. If that makes any sense. An since you haven't used midichlorians, I won't either, but the Veridians will think they've found something that explains it in their terms.
This is the same approach the Veridians will take with everything in the Universe that is seemingly "magical" or "god-like" that is being Rped. For them, science can explain everything lol
