A Penrose diagram, also called a conformal diagram, is a spacetime diagram that fits an infinite spacetime into a finite picture while preserving light-ray paths, introduced by Roger Penrose in 1963.
Penrose inequality
The Penrose inequality is a conjecture in general relativity relating the total mass of a spacetime to the area of the black hole horizons it contains.
Penrose interpretation
The Penrose interpretation is Roger Penrose's proposal that quantum wave function collapse is a real physical process caused by gravity rather than measurement, known quantitatively as the Diósi–Penrose model.
