I agree, E=MC2 pretty much sums that up. I imagine mater as a form of energy folded up in on itself, many many times. The thing I have trouble getting my brain around is that it's always been there. I don't disagree with this, but being the finite sentient thing that I am, I've definitely gotta question whether or not I've got the organic makeup to actually grasp that fully. I am after all a by product of this.
