Abstract
This paper is a synthesis of previously
published material on the topic. We show that an
adequate mathematical model for the physical (i.e., perceptible
and therefore past) reality must be finite. A finite
approach to past proper time is given. Proper time turns out to
be proportional to the sum of the return probabilities of a
Bernoulli random walk.
