Interesting and challenging* article on the quantum nature of things:

Challenging for me, because of some unfamiliar physics and my tendency towards distraction; but also because I *still* have big problems with the mismatch between General Relativity's "Gravity is not a force" and everywhere else where it seems to be considered a field with gravitons as the force-carrying particles.

In the end, all of these are models, and I guess you pick the one that works best for you today. But it will be cool if we come up with a model that incorporates quantum theory and gravity.
