“…Other motivations come from the Mach's Principle, that played an important role in the development of General Relativity, as, for example, the Brans-Dicke theory in which the gravitational interaction is mediated by a scalar field as well as the tensor field of General Relativity and the gravitational constant G is not presumed to be constant but instead 1/G is replaced by a scalar field which can vary from place to place and with time. Another theory in accord with Mach's Principle is de Sitter Relativity initially proposed by Fantappié and subsequently developed by Arcidiacono and other authors [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. At present, both Brans-Dicke theory and de Sitter Relativity are generally held to be in agreement with observation.…”

More than one century is passed by the publication of special relativity and few less by the birth of general relativity. Despite the great experimental successes of these theories, the study of the universe, is plagued by numerous unsolved problems. For example one of the most problems in cosmology is the cosmological constant, which governs the expansion of the universe, also known as dark energy. A substantial portion, about 60%, of the mass-energy in the universe is in a form of mysterious energy that is pushing the cosmos apart at an accelerating rate. What is this energy, and where does it come from? Cosmologists have no real idea. Although given a similar name, there is another problem in cosmology, the so-called dark matter, which is actually unrelated to dark energy, except insofar as they involve things we don't understand. About 90% of the mass in the universe is in an apparently invisible form of matter that we call dark matter. This dark matter can only be measured by the gravitational pull it has on objects around it, and all galaxies we observe contain large halos of it, often extending for hundreds of thousands of light years beyond the edge of luminous matter. Is this dark matter actual matter, such as weakly interacting massive particles, or perhaps it is just an observational artifact caused by an improper theory of gravity? Another mystery is why there is so much more matter than antimatter in the universe. According to physical theories, these forms of matter are essentially equivalent, but conventional matter is observed in much greater abundances than antimatter. In this paper we summarily introduce the principal alternative theories proposed during one century of relativity.

“…It is plausible that cθ0 coincides with the classical electron radius (Licata & Chiatti, 2010;Chiatti, 2011), which also corresponds to the range of strong interactions. If this identification is correct, the nucleation of matter originates a spatially extended big bang, corresponding to the condition under which, in the conventional big bang model, the Universe would find itself at the end of the hadronic era.…”

“…An approach based on general principles and able to better investigate the De Sitter Universe appearing and its relationships with the known Big-Bang scenario is necessary. This is the aim of the Archaic Universe theory, developed by the author with Chiatti since 2006 and based on group methods of the projective relativity (Licata, 2006;Licata & Chiatti, 2009;2010;Chiatti, 2012).…”

The problem of initial singularity in cosmology, beyond the technical aspects, set the insurmountable limits of every description purely dynamics of the universe. In this brief note we present the main conceptual aspects of the Archaic Universe cosmological program. The adoption of a de Sitter pre-space as a structure of the quantum vacuum allows you to rethink the problem of time in cosmology by the relationship between the archaic non-local phase and the local observable Universe.

“…More specifically, the "archaic universe" theories go back to the group theoretical approaches proposed in the mentioned, classical works of Arcidiacono and Fantappié [121][122][123][124][125][126] wherein the Projective Relativity" was introduced. Let us recall some basic concepts.…”

Aim of this paper is trying to show the possible significance, and usefulness, of various non-selfadjoint operators for suitable Observables in non-relativistic and relativistic quantum mechanics, and in quantum electrodynamics: More specifically, this work starts dealing with: (i) the hermitian (but not selfadjoint) Time operator in non-relativistic quantum mechanics and in quantum electrodynamics; with (ii) idem, the introduction of Time and Space operators; and with (iii) the problem of the four-position and fourmomentum operators, each one with its hermitian and anti-hermitian parts, for relativistic spin-zero particles. Afterwards, other physical applications of non-selfadjoint (and even non-hermitian) operators are briefly discussed. We briefly mention how non-hermitian operators can indeed be used in physics [as it was done, elsewhere, for describing Unstable States]; and some considerations are added on the cases of the nuclear optical potential, of quantum dissipation, and in particular of an approach to the measurement problem in QM in terms of a chronon. This paper is largely based on work developed, along the years, in collaboration with V.S.Olkhovsky, and, in smaller parts, with P.Smrz, with R.H.A.Farias, and with S.P.Maydanyuk.
