Could there be more than one correct rule?

Yes, the concept of rule space relativity suggests that many rules can be equivalent, but each different rule will be appropriate for a different “observer”, or, more specifically, will be the rule suitable for an observer using a certain language to describe the universe. Our particular description language—based on our sensory experience, and the formal descriptions of existing physics—may well have enough freedom that it allows several possible consistent rules.
