Well, I have to mention that I don't have a formal education in theoretical physics, just a keen interest.

That being said, with all due respect, I think string theory is implausible in a fundamental way.  I think the process of forming a theory and then backforming a framework of postulates to support it, is rather flawed.  Not that such reasoning *can't* work, but I just think that one's statistical probability of being correct decreases in inverse proportion to how much you fly in the face of Occam's Razor.

As for spice and cognition, it is striking to me how much things seem to click into place as I re-enter the atmosphere.  My thinking feels very much more holographic, and subtle informational connections are illuminated in very interesting ways.  It almost makes me wonder if that kind of thing is precisely why entheogens are scheduled and banned, in spite of their being very nearly harmless.  But I tend to be pretty cynical about those things.

I have begun to form an idea about matter being analogous to a solid state of energy, with perhaps electricity corresponding to a liquid state, and light (photons) being the vapor state.  I haven't figured out plasma yet.
