Zachriel,

I should say that the authors did not make it easy to follow their paper by stressing the analogy with the expansion of the universe. That is a deterministic process: every galaxy recedes from every other galaxy (on sufficiently long length scales).

In contrast, here we are dealing with a stochastic process: proteins move toward and away from each other. One has to do averaging in order to see a trend. The concept of equilibrium, crucial to the understanding of this work, is not stressed frequently enough. It took me a while to realize its importance. Those Hubble diagrams surely did not help.

I suppose experts had an easier time, but I am glad I took time to understand this work. It is very nice.
