You're not going to get material evidence. Anyone who can is probably looking for money or other goods. They're usually a good sign to stay away from.
The proof I talk of, is personal. I look at it more like one would look at a Zero Knowledge proof: there's no such thing as 100% confidence, but (2^64-1)/(2^64) is pretty damn close to 100%. Same idea.
> Particularly with the Chaos mages, there is an indication of an extra fundamental force to reality- much like electricity would have seemed in the 1600s. Do you think this is the case? Or do you think there is some other interaction between the mind and the 4 normal fundamental forces?
I would accept this to be fact if we can find proof of this new force. But as for now, I'm operating under the fact that we know of 4 fundamental forces. I'm assuming that most magic and auras are actually specifically under EM, and not Weak/Strong/Gravity.
Although, some divinations I've done does seem to indicate that there might be another force, but not as a "force".. But more of interdimensional interference. If one accepts the Multiple Worlds Interpretation, there are a near-infinite amount of dimensions nearby. If they could interfere with each other, we could see effects percolate from seemingly nothing. My divinations also indicate that a likely area where we will first see this effect is with the EM_Drive. If this is shown to be proven correct, this is the first case of a reactionless drive--- The key here is a new phenomenon to investigate. Possibly leading to a new force.
> What theories do you have with regard to the prime mechanism of action in magic?
Hard to say. I'm doing the equivalent of firing bowling balls into a kilogram of solid gold, and trying to interpret its atomic structure...
