If one resolves the measurement problem by allowing a real physical process of wave collapse, it is the collapse dynamics which manifests the non-locality, and which resists the fully Relativistic formulation.

Non-locality appears at exactly the point where the "measurement problem" which infects standard quantum theory is resolved.

If the correct solution to the measurement problem does not involve local beables, or if those beables have no nonrelativistic analogs, then starting with nonrelativistic quantum mechanics is counterproductive. But one has to start somewhere...

The regrettably widespread opinion that there is no real non-locality inherent in the quantum theory is therefore deeply intertwined with the regrettably widespread opinion that the measurement problem can be painlessly solved without postulating either additional variables or any real collapse process.

Dynamical variables are what count in physics, not coordinate or gauge transformations.

[T]his is something that can't be defined locally. It's got to be defined globally, in the context of the system as a whole. ...[T]hat's a very difficult thing for physicists to cope with because we're used to formulating all our laws of physics as local laws, and not as global laws.

[I]n general relativistic observations there is no preferred independent time variable. What we measure are a number of variables, all on equal footing, and their relative evolution. ...[I]t can be equally read it as the evolution of the variable T₁ as a function of the variable T₂, or viceversa. Which of the two is the independent variable here?

Some problems simply do not yield to reductionist techniques, particularly those that are dependent on emergent phenomena.

Some authors state that the last stage in this chain of measurements involves "consciousness," or the "intellectual inner life" of the observer, by virtue of the "principle of psycho-physical parallelism." Other authors introduce a wave function for the entire universe. In this book, I shall refrain from using concepts that I do not understand.

Time appears in quantum mechanics as a continuous parameter which represents an abstraction of the dynamical role of the measurement apparatus. The requirement of invites the extension of this abstraction to include space and time coordinates. The implication that space-time localized measurements are a useful, if practically unrealizable idealization may be incorrect, but it is a grave error dismiss the concept on the basis of a priori notions of measurability.

The manner in which time and space are bound up with each other in the four-dimensional continuum is variable. It is difficult to express this variability of the cross-connections between space and time in simple language, and different interpretations of it are possible, corresponding to different mathematical transformations of the fundamental line-element, e.g. a different choice of the variable which we interpret as "time." Perhaps the best way we can express it is by saying that the solution of the field-equations of the theory of relativity shows that there is in the universe a tendency to change its scale, which at the present time results in an expansion, but may perhaps at other times become, or have been, a shrinking. This is true of the grand scale model of the universe.

So long as mathematicians can impose up-and-down semantics upon students while trafficking personally in the non-up-and-down advantages of their concise statements, they can impose upon the ignorance of man a monopoly of access to accurate processing of information and can fool even themselves by thought habits governing the becoming behavior of professional specialists, by disclaiming the necessity of, or responsibility for, comprehensive adjustment of the a priori thought to total reality of universal principles. The everywhere-relative velocities and momentums of interactions, of energetic phenomena of universe, are central to the preoccupations and realizations of the comprehensive designer. The concept of relativity involves high frequency of re-established awareness, and progressively integrating consideration of the respective, and also integrated dynamic complexities of the moving and transforming frame of reference and of the integrated dynamic complexities of the observed, as well as of the series of integrated sub-dynamic complexities, in respect to each of the major categories of the relatively moving frames of reference, of the observer and the observed. It also involves constant reference of all the reciprocating sub-sets to the comprehensive totality of non-simultaneous universe, from which naught may be lost.

While non-relativistic time is the observable quantity measured (or approximated) by physical clocks, in general relativity clocks measure s along their worldline, not t. The relativistic... t is a freely chosen label with no direct physical interpretation. ...The physical content of a solution of Einstein's equations is not in its dependence on t, but ...in what remains once the dependence on t (and x) has been factored away.

At the most elemental level, reality evanesces into something called Schröedinger's Wave Function: a mathematical abstraction which is best represented as a pattern in an infinite-dimensional space, Hilbert Space. Each point of the Hilbert Space represents a possible state of affairs. The wave function for some one physical or mental system takes the form of, let us say, a coloring in of Hilbert Space. The brightly colored parts represent likely states for the system, the dim parts represent less probable states of affairs.
