Penrose thinks that there is some real, physical “collapse” of a quantum superposition as objects grow big enough for gravity to become a significant part of the picture. Therefore: quantum mechanics might break down when confronted with gravity – when objects get big enough to “feel” significant gravitational force – so quantum mechanics needs modifying or reinterpreting.
