Microscopic Rewrites and the Causal Network
1:04:54 - 1:10:48 (05:53)
The order of microscopic rewrites does not affect the causal network, which is the only phenomenon that affects the universe observer. The observer is only affected by the causal network of how events that happen in the universe lead to other events affecting themselves.

The only thing an observer can be affected by is the causal network of how events in the universe affect events in the observer, rather than the microscopic rewrites that happen within it.

Certain kinds of microscopic rewrite rules cause the causal network to be independent of the microscopic order of rewritings, which is essentially equivalent to a change of reference frame, and shows the property of causal invariance that implies a single thread of time in the universe.
