Among the various ideas put forward in the search for a theory
of quantum gravity, the causal set hypothesis is distinguished
by its logical simplicity and by the fact that it incorporates
the assumption of an underlying spacetime discreteness
organically and from the very beginning.

In the way that it has developed, the causal set hypothesis has
given rise to a mathematical framework (the "dynamics of
sequential growth") in which time is an active process of
"becoming" that can be identified with the continual birth of
new elements of the causal set.
