Background/introduction: This study is to discover the nature of consciousness and/or universe. Methods: Comparing the nature to a Game of Life system. Results: Found that the universe and a Game of Life system has the similar mathematical nature. Conclusions: Humans are limited in what they know by the technical limitation of their cortical language network. A reality is a situation model. The universe is a self-driven objective state machine which evolves by itself automatically. Heisenberg’s uncertainty principle can be explained under this situation. If we are happy to accept randomness, it’s obviously possible that all other worlds in the many-worlds interpretation don’t exist objectively. Consciousness is actually the use of a mathematical model by a Turing machine (TM). A TM’s consciousness or decisions shouldn’t be able to alter/impact/change the fated world line of any elementary particle within this world. Except Schrodinger equation (or its counterpart) which is the only actual causality of the objective-reality, any other causality is only a (subjective) Granger causality.
