  I take non-locality to be the Michaelson Morley experiment of the 21st
Century, assume its universal validity, and try to derive its consequences.
Spacetime, with its locality, cannot be fundamental, but emergent from
entangled coherent quantum variables and their behaviors. Two consequences: i.
If we start with non-locality, we need not explain non-locality. We must
explain an emergence of locality and spacetime. ii. There can be no emergence
of spacetime without matter. This contradicts General Relativity, which is
local, formulatable without matter and without an emergence of spacetime.
Quantum gravity cannot be a minor alteration of General Relativity. This will
lead to: Matter not only deforms spacetime, but creates spacetime. This quantum
creation of spacetime consists in: i. Fully non-local entangled coherent
quantum variables. ii. The onset of locality via decoherence. iii. A metric in
Hilbert Space among entangled quantum variables. iv. Mapping from metric
distances in Hilbert Space to metric distances in classical spacetime by
episodic actualization events. v. Discrete spacetime is the relations among
these discrete actualization events. vi. "Now" is the shared moment of
actualization of one among the entangled variables. vii. The discrete,
successive, episodic, irreversible actualization events constitute a quantum
arrow of time. viii. The arrow of time history of these events is recorded in
the very structure of the spacetime constructed. ix. Actual Time is a
succession of two or more actual events. Relation to Causal Set Theory,
faithful Lorentzian manifolds and light cones are discussed. The theory
inevitably yields a UV cut off. The cut off is a phase transition between
continuous spacetime before the transition and discontinuous spacetime beyond
the phase transition. This may predict the knee and ankle of the gamma ray
spectrum. Testing via the Casimir effect is proposed.
