A news article about a proposed experiment to test that philosophical question.
It does make sense that the behavior of the universe could be explained by interactions between “numbers.” Then anything seemingly paradoxical (e.g., particle/wave duality) is possible. We conceptualize and measure it as specific though un-intuitive physical behavior (both particle-like and wave-like, or string-like, or 21-dimensional, or some such conceptual model) but really it’s just a pattern of the numbers in the “computer”. We instantiate globs of rules to understand things which only really exist mathematically, where there’s not necessarily an “ultimate reality” to any of it, rather just relationships between structures. The universe is a giant cellular automaton, a massive thing similar to Conway’s “Game of Life”.
This is pretty trippy:
You’re watching particles of some other world.
[ And “light speed” in this world is laid bare to us, because a fundamental particle (one cell in the grid) cannot have influence on anything other than its neighboring cells, so information cannot exceed the speed of “light”; “light speed” is equal to one grid cell per clock cycle. ]
I speculate here that “God” is the computer, or whatever the simulation is running in. The “Godhead” is the brain’s perceptual representation of its grasp of the higher-level rules of the computer at the lowest level comprehensible to it, in its most fundamental “language.”
