High Quality Content by WIKIPEDIA articles! The Penrose interpretation is a prediction of Sir Roger Penrose (born 1931) about the relationship between quantum mechanics and general relativity. Penrose proposes that a quantum state remains in superposition until the difference of space-time curvature attains a significant level. This idea is inspired by quantum gravity, because it uses both the physical constants and . It is an alternative to the Copenhagen interpretation, which posits that superposition fails when an observation is made, and the many worlds hypothesis, which states that alternative outcomes of a superposition are equally "real", while their mutual decoherence precludes subsequent observable interactions.
