The Universe Cannot Be a Simulation: Physicists Prove Quantum Reality Cannot Be Digitized

The hypothesis that the physical reality surrounding us is a computer simulation has long since outgrown the realm of science fiction. In academic circles, it is discussed in the context of the concept of "digital physics," formulated by physicist John Wheeler in the thesis "it from bit," and in the philosophical works of Nick Bostrom. The logic of this idea is extremely concrete: if the fundamental laws of nature are fundamentally computable, then the behavior of any closed physical system can be simulated with any predetermined accuracy on a sufficiently powerful classical computer—a discrete Turing machine operating on finite arrays of zeros and ones. At the heart of any classical simulator lies an immutable law: information exchange between modeled nodes…
