This post catches up with a nice paper published last year by Sam Baron and Baptiste Le Bihan called “Causal Set Theory is (Strongly) Causal.” (A post about a previous, related paper by the same authors is here.) Causal Set Theory (CST) is an approach to quantum gravity that features discrete, causally linked foundational elements,… Continue reading More About the “Causal” in CST

The “Causal” in a Causal Theory of Spacetime
Across several posts, I have outlined how a causal process theory can provide an attractive ontology for phenomena described by the natural sciences, from quantum physics to biology. An exception, mentioned in a recent post, is that I haven’t had much to say about the spacetime of general relativity (GR). This topic is complicated by… Continue reading The “Causal” in a Causal Theory of Spacetime
Questions About Time and Space
The last post presented a version of causal process theory as a framework for ontology. The world is fundamentally a causal network, made up of persisting causal processes that participate in change-producing interaction events. As I mentioned, many details would need to be filled in to have a more complete picture. Below, I tackle a… Continue reading Questions About Time and Space
