Query: Berkelian Idealism Regarding Properties in Orthodox Quantum Mechanics,
  and Implications for Quantum Gravity   Referring to the 18th century idealism of George Berkeley in which an object
exists if and only if it is observed, this note shows that orthodox quantum
mechanics (OQM) entails a Berkelian idealism regarding properties (BIRP): a
quantum `has' a property X with quantitative value x if and only if the
property X has just been measured with outcome x. It is then impossible to
recontextualize GR's principle of curvature in any quantum framework that
implies this BIRP, for a quantum cannot curve space-time if it doesn't have a
definite energy - which is supposed to be the cause of curvature - in absence
of observation to begin with. Concluding, it is ruled out that a quantum theory
of gravity, in which GR's principle of curvature is built in as a fundamental
physical principle, can be developed in any framework implying this BIRP.
