An explanation for quantum mechanics is given in terms of a classical theory
(general relativity) for the first time. Specifically, it is shown that certain structures
in classical general relativity can give rise to the non-classical logic normally
associated with quantum mechanics.
An artificial classical model of quantum logic is constructed to show how
the Hilbert space structure of quantum mechanics is a natural way to describe a
measurement-dependent stochastic process.
A 4-geon model of an elementary particle is proposed which is asymptotically
flat, particle-like and has a non-trivial causal structure. The usual Cauchy data are
no longer sufficient to determine a unique evolution; the measurement apparatus
itself can impose further non-redundant boundary conditions. When measurements
of an object provide additional non-redundant boundary conditions, the associated
propositions would fail to satisfy the distributive law of classical physics.
Using the 4-geon model, an orthomodular lattice of propositions, characteristic
of quantum mechanics, is formally constructed within the framework of classical
The model described provides a classical gravitational basis for quantum
mechanics, obviating the need for quantum gravity. The equations of quantum mechanics
are unmodified, but quantum behaviour is not universal; classical particles
and waves could exist and there is no graviton.
