The causal set and Wolfram model approaches to discrete quantum gravity both permit the
formulation of a manifestly covariant notion of entanglement entropy for quantum fields. In …

The celebrated geodesic congruence equation of Raychaudhuri, together with the resulting
singularity theorems of Penrose and Hawking that it enabled, yield a highly general set of …

The formal relationship between two differing approaches to the description of spacetime as
an intrinsically discrete mathematical structure, namely causal set theory and the Wolfram …

The causal set program and the Wolfram physics project leave open the problem of how a
graph that is a (3+ 1)-dimensional Minkowski spacetime according to its simple geodesic …

Spacetime computing is undoubtedly one of the most ambitious and less explored forms of
unconventional computing. Totally unconventional is the medium on which the computation …

This document describes a correspondence between photons and propagating information
packets (PIPs) that are emergent out of the Space Element Reduction Duplication (SERD) …

Several classes of directed acyclic graphs have been investigated in the last two decades, in
the context of the causal set program, in search for good discrete models of spacetime. We …

After some reflection on the messages that I have found most inspiring in Wolfram's NKS
book, ten years after its publication, in this paper I speculate on a few, highly attractive new …

The concept of emergence is a powerful way to explain very complex behavior by simple
underlying rules. Existing approaches to producing emergent collective behavior have many …

The causal set program and the Wolfram physics project leave open the problem of how a
graph that is a (3+ 1)-dimensional Minkowski spacetime according to its simple geodesic …
