Operational General Relativity: Possibilistic, Probabilistic, and Quantum

Understand

In this paper we develop an operational formulation of General Relativity similar in spirit to existing operational formulations of Quantum Theory.

• To do this we introduce an operational space (or op-space) built out of scalar fields.
• A point in op-space corresponds to some nominated set of scalar fields taking some given values in coincidence.
• We assert that op-space is the space in which we observe the world.
