In 1814, Jean-Pierre Laplace theorized that if a being existed that could know the exact location and speed of every atom in the universe and could process all of that information instantaneously, it could predict exactly what would happen at any given place or time. The name for this fictional being was Laplace’s Demon, and it was intended to illustrate the application of physics. Since that time, ideas like thermodynamics and chaos theory have been provided as contradictions, opposing that idea that such structure exists in the universe. It’s a thought experiment about the idea of something being random and to what extent information becomes useful as a predictor for future events.
