scholarly journals Recovery of Global Symmetries in a 't Hooftian Universe

Author(s):  
Alexandre Furtado Neto

All fundamental Planck scale symmetries are restored on a global level when a new charge is postulated in a finite, closed, Euclidean discrete space. Gravity emerges as a residual effect of the electromagnetic force in this scenario, resulting in a deterministic toy universe driven by a single input parameter. The model is developed using a constructive approach. Randomness is identified using a Chaintin argument. Aleph0 definite value is tied to the size of the universe. This is not an interpretation of Quantum Mechanics, but a deeper attempt to describe nature.

A non-probabilistic interpretation of quantum mechanics asserts that we get a prediction only when a wave function has a peak. Taking this interpretation seriously, we discuss how to find a peak in the wave function of the universe, by using some minisuperspace models with homogeneous degrees of freedom and also a model with cosmological perturbations. Then we show how to recover our classical picture of the universe from the quantum theory, and comment on the physical meaning of the backreaction equation.

Imagine a model of the universe that, if true and known to be true, would solve the following philosophical problems: the direction and flow of time, an ontology for laws of nature, the interpretation of quantum mechanics, the interpretation of probability, a semantics for counterfactuals, trans-world and trans-temporal identity, essentialism and natural kinds, and free will and responsibility. The successful solution to these problems would convince most of us that we should, at the very least, give this model serious consideration. This is the argument of Storrs McCall's A Model of the Universe: Space-Time, Probability, and Decision. Assume that the branched-tree model of the universe is true, and all these problems are solved. Thus, the branched-tree model should at least be a plausible candidate for the true model of the universe.

AbstractThe Many-Worlds Interpretation (MWI) is a theory in physics which proposes that, rather than quantum-level events being resolved randomly as according to the Copenhagen Interpretation, the universe constantly divides into different versions or worlds. All physically possible worlds occur, though some outcomes are more likely than others, and therefore all possible histories exist. This paper explores some implications of this for history, especially concerning causation. Unlike counterfactuals, which concern different starting conditions, MWI concerns different outcomes of the same starting conditions. It is argued that analysis of causation needs to take into account the divergence of outcomes and the possibility that we inhabit a less probable world. Another implication of MWI is convergent history: for any given world there will be similar worlds which are the result of different pasts which are, however, more or less probable. MWI can assist in thinking about historical causation and indicates the importance of probabilistic causation.

Resumen: Este comentario aprecia la metodología realista e interdisciplinar de la obra Los sótanos del universo. Se dialoga con el autor sobre el valor epistemológico del azar; la interpretación de la mecánica cuántica y la posibilidad de reducción en los sistemas dinámicos complejos. Se destaca por último la finalidad ínsita en la inteligibilidad del universo como vía de apertura de la ciencia a la trascendencia.Palabras clave: inteligibilidad del universo; finalidad; interdisciplinariedad.Abstract: This article appreciates the realistic and interdisciplinary approach of the book Los sótanos del universo. It debates with the author on the epistemic value of randomness; the interpretation of Quantum Mechanics and the possibility of reduction for complex dynamical systems. It finally highlights the inherent purpose associated to the intelligibility of the universe as a way of opening science to transcendence.Keywords: Intelligibility of the Universe; Purpose; Interdisciplinarity.Recibido: 4 de junio de 2013.

In this paper a new small parameter associated with the density matrix deformation (density pro-matrix) studied in previous works of the author is introduced into the Generalized Quantum Mechanics (GQM), i.e. quantum mechanics involving description of the Early Universe. It is noted that this parameter has its counterpart in the Generalized Statistical Mechanics. Both parameters offer a number of merits: they are dimensionless, varying over the interval from 0 to 1/4, and assuming in this interval a discrete series of values. Besides, their definitions contain all the fundamental constants. These parameters are very small for the conventional scales and temperatures, e.g. the value of the first parameter is on the order of ≈10-66+2n, where 10-n is the measuring scale and the Planck scale ~ 10-33cm is assumed. The second one is also too small for the conventional temperatures, that is those much below the Planck temperature. It is demonstrated that relative to the first of these parameters the Universe may be considered as a nonuniform lattice in the four-dimensional hypercube with dimensionless finite-length (1/4) edges. And the time variable is also described by one of the above-mentioned dimensions due to the second parameter and Generalized Uncertainty Relation in thermodynamics. In this context the lattice is understood as a deformation rather than approximation.

In the last years, many different primeval quantization theories on the Planck scale have been developed. Their goal is to provide a vacuum model able to ground the research beyond the Standard Model. Despite their goal is quite ambitious and aims toward particle physics, a necessary and notable consequence is we can read Quantum Mechanics from an emergent viewpoint. Different hypotheses on elementary cells are possible. We will focus here on the conceptual features of G. ’t Hooft and F.Winterberg theories with a special attention for the emerging of non-local correlations. These theories define a new style in the interpretation of Quantum Mechanics.
