I think this might relate to what he discusses at the end of the very long Project Announcement blog/article. Something like there may be many different rules, but the one we find will be correct for us due to the framework we have for evaluating the universe (senses, math, etc.).
If it's correct to the framework we have--do we have "a framework" for evaluating the universe? It seems more like there are many. Within senses--millions of frameworks. Within math, millions. And for good reason; this lens offers a different look at this aspect, and this other lens offers a singular view of that one. Stars are white. Stars are blue or red or yellow. Stars have no color. All of these true and helpful, and also conflicting in some context or another.
Looking at the way he's evaluating universes and aiming to find one that's so well matched to ours, just intuitively I also have to wonder how many different ways there are of modeling our universe that are worth keeping around no matter how poorly they fit in even some big ways.
