Here is a fun philosophical question I wonder about sometimes, given that my background is in computer science and not physics. In the field of computer science, a Turing Machine is considered to be able to carry out any computation. So, philosophically, could the universe be thought of as a type of computation? And therefore, is the universe a type of Turing Machine? Are there any processes/behaviors in the universe that could not be modeled by a Turing Machine?
