Following Smolin, we proceed to unification of general relativity and quantum theory by
operating solely with events, ie, without appealing to physical systems and space-time. The
universe is modelled as a dendrogram (finite tree) expressing the hierarchic relations
between events. This is the observational (epistemic) model; the ontic model is based on p-
adic numbers (infinite trees). Hence, we use novel mathematics: not only space-time but
even real numbers are not in use. Here, the p-adic space (which is zero-dimensional) serves …
