Ah, but there IS something there about spiritual beings. A theist CLAIMS that such a being, being spirit, is immaterial--meaning no physical substance. Now, that falls under the purview of physics. My equation (based on Einstein's equations in relativity) is:

P = (mc/t)*sqrt(c^2 + v^2*gamma^2)

With an immaterial spirit being, we have that its mass is zero. We plug in zero for m in the above equation.

P = 0*stuff

We learn in very early math classes that zero is a multiplicative killer. Thus, zero times anything is zero. Thus, P = 0, which the power of a spirit being is zero.

Again, I am sorry, but in our universe, spirits don't exist because they all have zero power.

Peace my friend,

Tony
