Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem”

In 1964, John Stewart Bell famously demonstrated that the laws of standard quantum mechanics demand a physical world that cannot be described entirely according to local laws.  The present article argues that this non-locality must be gravitationally related, as it comes about only with quantum state reduction, this being claimed a gravitational effect. A new formalism for curved space-times, palatial twistor theory is outlined, which appears now to be able to accommodate gravitation fully, providing a non-local description of the physical world.
