  1. L'ontologie des singularités.Nicolae Sfetcu - manuscript
    La relativité générale permet les singularités et nous devons comprendre l'ontologie si nous voulons comprendre la nature de l'espace et du temps dans l'univers d'aujourd'hui. Bien que certains physiciens pensent que les singularités indiquent un échec de la relativité générale, d'autres pensent que les singularités ouvrent un nouvel horizon dans la cosmologie, avec de réels phénomènes physiques pouvant contribuer à un progrès profond dans notre compréhension du monde.

  • The Ontology of General Relativity.Nicolae Sfetcu - 2019
    General Relativity generated various early philosophical interpretations. His adherents have highlighted the "relativization of inertia" and the concept of simultaneity, Kantians and Neo-Kantians have underlined the approach of certain synthetic "intellectual forms" (especially the principle of general covariance, and logical empirics have emphasized the philosophical methodological significance of the theory. Reichenbach approached the GR through the "relativity of geometry" thesis, trying to build a "constructive axiomatization" of relativity based on "elementary matters of fact" (Elementartatbestande) for the observable behavior of light (...)

  • Introduction dans les théories de la relativité.Nicolae Sfetcu - manuscript
    Selon la relativité générale, la force gravitationnelle est une manifestation de la géométrie de l'espace-temps local. RG est une théorie métrique de la gravité. Il est basé sur les équations d'Einstein, qui décrivent la relation entre la géométrie d'une variété pseudo-riemannienne à quatre dimensions, représentant l'espace-temps et l'énergie-impulsion contenu dans cet espace-temps. La gravité correspond aux modifications des propriétés spatiales et temporelles, qui à leur tour modifient les chemins des objets. La courbure est causée par l'énergie-impulsion de la matière. Selon (...)

  • Classical theory of singularities.Nicolae Sfetcu - manuscript
    The singularities from the general relativity resulting by solving Einstein's equations were and still are the subject of many scientific debates: Are there singularities in spacetime, or not? Big Bang was an initial singularity? If singularities exist, what is their ontology? Is the general theory of relativity a theory that has shown its limits in this case?

  • Singularitățile ca limite ontologice ale relativității generale.Nicolae Sfetcu - manuscript
    Singularitățile la care se ajunge în relativitatea generală prin rezolvarea ecuațiilor lui Einstein au fost și încă mai sunt subiectul a numeroase dezbateri științifice: Există sau nu, singularități? Big Bang a fost o singularitate inițială? Dacă singularitățile există, care este ontologia acestora? Este teoria generală a relativității o teorie care și-a arătat limitele în acest caz? În acest eseu argumentez faptul că există singularități, iar teoria generală a relativității, ca de altfel oricare altă teorie științifică din prezent, nu este valabilă (...)

  • Ontology of Gravitational Singularities.Nicolae Sfetcu - manuscript
    General relativity allows singularities, and we need to understand the ontology of singularities if we want to understand the nature of space and time in the present universe. Although some physicists believe that singularities indicate a failure of general relativity, others believe that singularities open a new horizon in cosmology, with real physical phenomena that can help deepen our understanding of the world. From the definitions of singularities, most known are the possibility that some spacetimes contain incomplete paths (most accepted), (...)

  • Gravitational Singularities.Nicolae Sfetcu - manuscript
    Gravitational singularities in general relativity are spacetime locations where the gravitational field becomes infinite. Scalar invariant curves of spacetime include a measure of matter density. Some physicists and philosophers believe that because the density of matter tends to become infinite in singularity, spacetime laws are no longer valid there. A gravitational singularity almost universally accepted in astrophysics and cosmology as the earliest state of the universe, is the Big Bang. In this case also, the known laws of physics are no (...)
