## The digital filter analogy

The fact that the age of the universe $$\simeq 1/H_0$$ suggests that cosmological dynamics must incorporate some form of negative feedback.  Couple this with the Holochronous Principle, whereby the universe retains the gravitational histories of all the matter it contains, and the fact that this gravitational imprint propagates at the speed of light, and you have all the ingredients required for a digital filter system.
