The simulation hypothesis proposes that what we experience as the world is actually a simulated reality, such as a computer simulation in which we ourselves are constructs.[1][2] There has been much debate over this topic in the philosophical discourse, and regarding practical applications in computing.

"Turtles all the way down" is an expression of the problem of infinite regress. The saying alludes to the mythological idea of a World Turtle that supports a flat Earth on its back. It suggests that this turtle rests on the back of an even larger turtle, which itself is part of a column of increasingly larger turtles that continues indefinitely.
