Our work consists on showing that the Spacetime curvature introduced by Einstein in the Universe and also in the Brain is a result of the Information Entropy of different quantum Paths of elementary particles (leptons, bosons…) of path integrals model. We started by seeing the structure of how the incoming information is processed and then propagated in the brain and how the latter is deformed in each neuron to thus create a potential reaction response distorted or not. In quantum physics, and particularly in quantum field theory (QFT), the paths in path integrals have an equivalent role to paths between two neighboring linked neurons (synapses + neurotransmitters + dendrites). Using this modeling, we prove mathematically that the entropy of the Information coming from the paths could be equivalent to the Spacetime curvature in Universe as in Brain

In “What Flashes Up,” Karen Barad exposes a startling new sense of matter. The “agential realist” interpretation of quantum physics in her monumental Meeting the Universe Halfway had already brought the indeterminacy and relationality—the “intra-activity”—of quantum ontology into resonance with human ethics: All beings compose and partake in the responsive structure of the world. “Intra-acting responsibly as part of the world means taking account of the entangled phenomena that are intrinsic to the world’s vitality and being responsive to the possibilities that might help us flourish.” In the present discussion, Barad draws Walter Benjamin’s messianic “now-time” via Judith Butler and quantum field theory into a deep meditation on the matter of time, a time that breaks from the scientific and political modernisms of purportedly linear progress.

Dirac Conjugation

We have developed a quantum field theory of spinors based on the algebra of canonical anticommutation relations (CAR algebra) of Grassmann densities in the momentum space. We have proven the existence of two spinor vacua. Operators C and T transform the normal vacuum into an alternative one, which leads to the breaking of the C and T symmetries. The CPT is the real structure operator; it preserves the normal vacuum. We have proven that, in the theory of the Dirac Sea, the formula for the charge conjugation operator must contain an additional generalized Dirac conjugation operator.

The vacuum catastrophe results from the disagreement between the theoretical value of the energy density of the vacuum in quantum field theory and the estimated one observed in cosmology. In a similar attempt in which the ultraviolet catastrophe was solved, we search for the value of the cosmological constant by brute-force through computation. We explore combinations of the fundamental constants in physics performing a dimensional analysis, in search of an equation resulting in the measured energy density of the vacuum or cosmological constant that is assumed to cause the accelerated expansion of the universe.

ResumenLos abundantes análisis filosóficos sobre la física cuántica no se han visto en general acompa- ñados por una consideración equiparable hacia su prolongación natural en la teoría cuántica de campos. Esta teoría se ha revelado en su versión electromagnética como una de las herramientas predictivas más precisas de la ciencia física. No obstante, sus cimientos conceptuales siguen siendo altamente controvertidos y cabe dudar si una ampliación de su formalismo conducirá a la tan deseada unificación de las fuerzas fundamentales, y por ende, a una comprensión global de las propiedades básicas de la naturaleza.Palabras claveFilosofía de la física, teoría cuántica de campos, unificación de fuerzas, predicciónAbstractThe abundant philosophical analyses on quantum physics have not been generally followed by an equivalent consideration toward their natural continuation in the quantum field theory. This theory is regarded in its electromagnetic version as one of the best predictive tools in physical science. Nevertheless, its conceptual foundations are still surrounded by controversy and it is doubtful if an extension of its formalism will lead us to the unification of the four basic forces, and therefore to a global understanding of the basic properties of nature.KeywordsPhilosophy of physics, quantum field theory, unification of forces, prediction

Continuity And Discontinuity

While most new materialists, including Thomas Nail, tend to distance themselves from Deleuze, this essay reads the encounter of Nail's ‘process materialism’ and Deleuzian philosophy as productive rather than contentious. After tracing the affinities of their notions of continuity and discontinuity by way of Deleuze's The Fold: Leibniz and the Baroque and Nail's Lucretius I: An Ontology of Motion and Being and Motion, the essay considers Nail's unfolding of Lucretius’ luminous philosophy in relation to Deleuze's reading of Lucretius from within Deleuze's own ‘philosophical luminism’. Within the multiple overlaps between Nail and Deleuze, particularly vis-à-vis quantum physics and quantum field theory, their divergent readings of the particle–wave duality bring about a productive conceptual tension. Nail's argument about the ontological precedence of waves over particles (‘process precedes existence’) is illuminated by Deleuze's concept of their ontological complementarity (actual particles and virtual waves, virtual particles and actual waves), and vice versa.

Friedmann Robertson Walker

The standard cosmological solutions of Einstein's equations of general relativity describe a fluid that is homogeneous and isotropic in density and pressure. These solutions, often called the Friedmann–Robertson–Walker solutions, are believed to be good descriptions of the universe at the present time. But early on, processes connected with particle physics and quantum field theory may have caused localized inhomogeneities, and recently some new kinds of solution of Einstein's equations have been found, which may describe such regions. In one solution being studied by Wesson and Ponce de Leon (Phys. Rev. D: Part. Fields, 39, 420 (1989)), the density is still uniform but the pressure is nonuniform about a centre. The mass is given by a relation that looks like the familiar Newtonian relation m = (4/3)πR3ρ. However, the solution has other properties that are quite strange (e.g. a region of negative pressure and a kind of dipolar geometry). It is not known if solutions like this are merely mathematical curiosities or imply something about the behaviour of real matter in extreme situations.

The Brain

We derive time evolution equations, namely the Klein–Gordon equations for coherent fields and the Kadanoff–Baym equations in quantum electrodynamics (QED) for open systems (with a central region and two reservoirs) as a practical model of quantum field theory of the brain. Next, we introduce a kinetic entropy current and show the H-theorem in the Hartree–Fock approximation with the leading-order (LO) tunneling variable expansion in the 1st order approximation for the gradient expansion. Finally, we find the total conserved energy and the potential energy for time evolution equations in a spatially homogeneous system. We derive the Josephson current due to quantum tunneling between neighbouring regions by starting with the two-particle irreducible effective action technique. As an example of potential applications, we can analyze microtubules coupled to a water battery surrounded by a biochemical energy supply. Our approach can be also applied to the information transfer between two coherent regions via microtubules or that in networks (the central region and the N res reservoirs) with the presence of quantum tunneling.
