Simulation Hypothesis

The Simulation Hypothesis is the proposal that our perceived reality is a computational simulation created by a more advanced civilization. The argument, most prominently developed by Nick Bostrom, reasons that if technologically mature civilizations are likely to run ancestor simulations, and if each simulation contains many simulated minds, then the number of simulated observers would vastly exceed the number of biological observers — making it probable that we are among the simulated.\n\nThe hypothesis raises questions at the intersection of philosophy of mind, computation theory, and anthropic reasoning. It is a special case of the broader observer-selection problem: what should we infer from the fact that we find ourselves in a particular kind of reality? The hypothesis is not empirically testable in any straightforward way, but it has generated productive debates about the nature of consciousness, the limits of computational physics, and the structure of observer-selection arguments.\n\n\n
