I consider equilibrium to be similar to infinity. One can approach it while never actually getting there. Much like continual halving will approach zero while never getting there.

So the idea is that eventually the universe will be expanding faster than light speed? That's gonna take some time to wrap my head around. How can this ever happen? Does this mean new space is being created between two given particles? Or that one particle is moving away from another at >c, creating the illusion of "expanding" space?
