Simulation hypothesis

The Simulation hypothesis is a proposition that what we perceive to be physical reality, including all observable, measurable events (potentially to the quantum scale), are purely virtual in nature, being the artificial product of a simulator rather than being the real in and of itself, a form of hyperreality. The nature of the simulator is unknown, but is often presumed to be computational in nature, the supposition being that it may operate similarly to how a computer may be used to generate simulated realities, as in the form of video games.
