A Vast Space of Possibilities
The set of possible rules that could govern the universe is vast and infinite. This poses an intriguing conundrum: why did we end up with a relatively simple rule instead of a more complex one? After all, if there are countless possibilities, how did we become the lucky winners of a simpler rule?
A Bizarre Twist
The situation becomes even more mind-boggling when considering the concept of multi-way graphs. Imagine not only applying a specific rule wherever it is applicable but also applying all possible rules in all possible ways simultaneously. Sounds insanely complicated, right? Surprisingly, this results in a fascinating feature called causal invariance.
Causal Invariance
The rule multi-way graph, created by the application of all possible rules in all possible ways, inherently possesses causal invariance. This means that different reference frames within this graph can be considered equivalent with the right translation. In other words, regardless of how we slice and interpret the graph, the result remains the same.
Unlocking the Beautiful Mathematics
The mathematical foundation for this phenomenon lies in higher category theory, groupoids, and computational complexity theory. These seemingly unrelated fields offer a deeper understanding of the space of all possible rules and the transformations that occur within hypergraphs.
A Turing Machine Insight
One powerful model of computation, the Turing machine, helps shed light on this complex topic. While deterministic Turing machines follow a single path, non-deterministic Turing machines explore a multitude of branching possibilities. By considering an extreme non-deterministic Turing machine that can accommodate any possible rule at each step, we arrive at the rule multi-way graph—a representation of all possible histories.
The Observer’s Role
When we, as observers, try to make sense of the universe, we choose a reference frame within the rule multi-way graph. It is within this frame that we infer the rule governing the universe. However, it’s important to note that different reference frames can lead to completely different descriptions of the universe, making our interpretation subjective.
A Multitude of Universes
Think about how we perceive the universe—our senses, our size, and our cognitive abilities shape our understanding. However, there are countless other reference frames that yield incoherent descriptions of the universe. Each reference frame within the rule space gives rise to a unique interpretation.
Embracing the Complexity
The mystery of the universe’s rules unfolds before us, revealing a breathtaking tapestry of complexity. As we explore the vast space of all possible rules, we begin to comprehend the intricacies that underpin our existence.

FAQs
Q: How did we end up with a simpler rule for the universe?
A: The selection of a particular rule within the space of all possible rules is determined by our choice of reference frame and our subjective interpretation.
Q: Can different reference frames lead to different descriptions of the universe?
A: Yes, choosing different reference frames within the rule space can result in contrasting descriptions of the universe.
Conclusion
The rules that govern our universe are a captivating enigma. Through the exploration of multi-way graphs, causal invariance, and the vast space of all possible rules, we gain insights into the complexity and beauty of our existence. As we continue to unravel the secrets of the universe, let us marvel at its boundless wonders.
