Is a theory of everything possible? Critical reflections and variations on the theme (È possibile una teoria del tutto? Riflessioni critiche e variazioni sul tema)

The evolution of the history of physics shows how natural phenomena can be grouped into discrete regimes, between which there are precise relationships and specific connecting elements but which, with an excellent approximation, can be considered independent of each other. Here it is clarified, in the light of developments in contemporary physics, in what sense theory of everything means "theory that aims to explain a specific and limited level of energy", highlighting the link between the world we experience daily and the background of the theories of everything.Keywords: theories of everything; quantum gravity; principle of collective organizationSuntoL’evoluzione della storia della fisica mostra come i fenomeni naturali possono essere raggruppati in regimi discreti, tra cui esistono precise relazioni e specifici elementi di raccordo ma che, con un’ottima approssimazione, si possono considerare indipendenti l’uno dall’altro. Qui si chiarisce, alla luce degli sviluppi della fisica contemporanea, in che senso teoria del tutto significa “teoria che si propone di spiegare un livello di energia specifico e limitato”, evidenziando il legame tra il mondo che sperimentiamo quotidianamente e il background delle teorie del tutto.Parole Chiave: teorie del tutto; gravità quantistica; principio di organizzazione collettiva

Dynamic Quantum Vacuum and Relativity

A model of a three-dimensional dynamic quantum vacuum with variable energy density is proposed. In this model, time we measure with clocks is only a mathematical parameter of changes running in quantum vacuum. Mass and gravity are carried by the variable energy density of quantum vacuum. Each elementary particle is a structure of quantum vacuum and diminishes the quantum vacuum energy density. Symmetry “particle – diminished energy density of quantum vacuum” is the fundamental symmetry of the universe which gives origin to the inertial and gravitational mass. Special relativity’s Sagnac effect in GPS system and important predictions of general relativity such as precessions of the planets, the Shapiro time delay of light signals in a gravitational field and the geodetic and frame-dragging effects recently tested by Gravity Probe B, have origin in the dynamics of the quantum vacuum which rotates with the earth

About a new suggested interpretation of special theory of relativity within a three-dimensional Euclid space

An  interpretation  of  special  theory  of  relativity  is  proposed,  in  which  the  fundamental  arena  of  physical processes is an Euclid three-dimensional space where time exists only as a numerical order of  material  changes  and  the  duration  of  material  changes  is  a  proper,  physical  scaling  function  of  the  numerical  order.  This  model  introduces  interesting  perspectives  in  the  study  of  several  phenomena  inside  special  relativity,  such  as  aberration  of  light,  Doppler  effect,  Jupiter’s  satellites  occultation  and  radar  ranging  of  the  planets.Artykuł nie zawiera abstraktu w języku polski

Symmetry of mass and energy density of quantum vacuum

Mass is an energy form of quantum vacuum in symmetry with diminished energy density of quantum vacuum. Presence of mass diminishes energy density of quantum vacuum respectively to the energy of a given mass. A given particle with a mass diminishes energy density of quantum vacuum, mass-less particle does not diminish energy of quantum vacuum. In order to explain mass of elementary particles this view does not require existence of the hypothetical boson of Higgs

Block Universe - According to the Formalism X4 = ict Space-time is Timeless

According to the formalism d = v x t fourth dimension of space-time is spatial too. In formula X4 = ict symbol t represents numerical order of material change i.e. motion running in space. Flow of time is flow of numerical order of materal change that we measure with clocks. Fundamental unit of numerical order t0,t1,t2...tn of material change is a Planck time tp. Numerical order of material change tn-1 is "before" numerical order of material change tn equivalently as natural number n-1 is "before" natural number n. Flow of physical time is a flow of numerical order t0,t1,t2...tn of material change and runs in a timeles 4D space

Bell Length as Mutual Information in Quantum Interference

The necessity of a rigorously operative formulation of quantum mechanics, functional to the exigencies of quantum computing, has raised the interest again in the nature of probability and the inference in quantum mechanics. In this work, we show a relation among the probabilities of a quantum system in terms of information of non-local correlation by means of a new quantity, the Bell length

Quantum potential physics, geometry and algebra

Recently the interest in Bohm realist interpretation of quantum mechanics has grown. The important advantage of this approach lies in the possibility to introduce non-locality ab initio, and not as an “unexpected host”. In this book the authors give a detailed analysis of quantum potential, the non-locality term and its role in quantum cosmology and information. The different approaches to the quantum potential are analysed, starting from the original attempt to introduce a realism of particles trajectories (influenced by de Broglie’s pilot wave) to the recent dynamic interpretation provided by Goldstein, Durr, Tumulka and Zanghì, and the geometrodynamic picture, with suggestion about quantum gravity. Finally we focus on the algebraic reading of Hiley and Birkbeck school, that analyse the meaning of the non-local structure of the world, bringing important consequences for the space, time and information concepts
