We discuss how to embed quantum nonlocality in an approximately classical spacetime background, a question which must be answered irrespective of any underlying microscopic theory of spacetime. We argue that, in deterministic hidden-variables theories, the choice of spacetime kinematics should be dictated by the properties of generic non-equilibrium states, which allow nonlocal signalling. Such signalling provides an operational definition of absolute simultaneity, which may naturally be… 
Classical and quantum cosmology with York time
We consider a solution to the problem of time in quantum gravity by deparameterization of the ADM action in terms of York time, a parameter proportional to the extrinsic curvature of a spatial
Foundations of anisotropic relativistic mechanics
We lay down the foundations of particle dynamics in mechanical theories that satisfy the relativity principle and whose kinematics can be formulated employing reference frames of the type usually
Cosmological history in York time: inflation and perturbations
The constant mean extrinsic curvature on a spacelike slice may constitute a physically preferred time coordinate, ‘York time’. One line of enquiry to probe this idea is to understand processes in our
An extension of cosmological dynamics with York time
It has been suggested that the York parameter T (effectively the scalar extrinsic curvature of a spatial hypersurface) may play the role of a fundamental time parameter. In a flat, forever expanding
Quantum gravity and quantum probability
We argue that in quantum gravity there is no Born rule. The quantumgravity regime, described by a non-normalisable Wheeler-DeWitt wave functional Ψ, must be in quantum nonequilibrium with a
Pilot Wave Theory and Quantum Fields
Pilot wave theory (PWT), also called de Broglie-Bohm theory or Bohmian Mechanics, is a deterministic nonlocal `hidden variables' quantum theory without fundamental uncertainty. It is in agreement
Benefits of Objective Collapse Models for Cosmology and Quantum Gravity
We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applications of objective

It is argued that, while de Broglie's dynamics is a tenable physical theory, Bohm’s dynamics is not and there would be no reason to expect to see an effective quantum theory today, in contradiction with observation.
Statistical anisotropy and cosmological quantum relaxation
We show that cosmological quantum relaxation predicts an anisotropic primordial power spectrum with a specific dependence on wavenumber k. We explore some of the consequences for precision
Ju n 20 05 Generalizations of Quantum Mechanics
We review realistic models that reproduce quantum theory in some limit and yield potentially new physics outside that limit. In particular, we consider deterministic hidden-variables theories (such


Hidden Variables, Statistical Mechanics and the Early Universe
One of the central mysteries of quantum theory is that it seems to be fundamentally nonlocal—and yet the nonlocality cannot be used for practical signalling at a distance. The consistency of modern

Einstein's theory of gravity is reformulated so that the cosmological constant becomes an integration constant of the theory, rather than a coupling'' constant, and the key weakness'' of this formulation is that one must introduce a nondynamic background spacetime volume element.
The Large Scale Structure of Space-Time
The theory of the causal structure of a general space-time is developed, and is used to study black holes and to prove a number of theorems establishing the inevitability of singualarities under certain conditions.
Pilot-Wave Theory of Fields, Gravitation and Cosmology
Our universe is characterised by: (i) The absence of practical instantaneous signals (signal-locality), and (ii) An all-pervading statistical ‘noise’ (uncertainty principle). Now, as Bell deduced,
Signal-locality in hidden-variables theories
Gravity with a dynamical preferred frame
We study a generally covariant model in which local Lorentz invariance is broken "spontaneously" by a dynamical unit timelike vector field $u^a$---the "aether". Such a model makes it possible to

We study the origin of the Born probability rule ρ = |ψ|2 in the de Broglie–Bohm pilot–wave formulation of quantum theory. It is argued that quantum probabilities arise dynamically, and have a status
Nonlocality, Lorentz invariance, and Bohmian quantum theory.
A model invariant under a certain limit of Lorentz transformations, a limit retaining the characteristic feature of relativity, the nonexistence of absolute time, i.e., of simultaneity is presented.
Measurement understood through the quantum potential approach
We review briefly the quantum potential approach to quantum theory, and show that it yields a completely consistent account of the measurement process, including especially what has been called the
A Statistical Superfield and Its Observable Consequences
A new kind of fundamental superfield is proposed, with an Ising-like Euclidean action. Near the Planck energy it undergoes its first stage of symmetry breaking, and the ordered phase is assumed to
