The Ontology of General Relativity
The Ontology of General Relativity

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 … Citeşte mai mult

Grandfather paradox in time travel
Grandfather paradox in time travel

The most well-known example of the impossibility of traveling in time is the grandfather paradox or self-infanticide argument: a person who travels in the past and kills his own grandfather, thus preventing the existence of one of his parents and … Citeşte mai mult

Anomalii ale relativității generale
Anomalii ale relativității generale

În timp, teoria generală a relativității a acumulat mai multe anomalii și discrepanțe, indicând necesitatea unor teorii mai bune despre gravitație sau alte moduri de abordare. Ipotezele ad-hoc introduse în relativitatea generală pentru a explica singularitățile gravitaționale pe baza condițiilor … Citeşte mai mult

Introduction dans les théories de la relativité
Introduction dans les théories de la relativité

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 … Citeşte mai mult

Classical theory of singularities
Classical theory of singularities

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 … Citeşte mai mult

Hooke’s claim on the law of gravity
Hooke’s claim on the law of gravity

Based on Galileo’s experiments, Newton develops the theory of gravity in his first book Philosophiæ Naturalis Principia Mathematica („Principia„) of 1686. Immediately after, Robert Hooke accused Newton of plagiarism, claiming that he unduly assumed his „notion” of „the rule of … Citeşte mai mult

Newton’s action at a distance – Different views

Different authors have attempted to clarify the aspects of remote action and God’s involvement on the basis of textual investigations, mainly from the Mathematical Principles of Natural Philosophy, Newton’s correspondence with Richard Bentley (1692/93), and Queries that Newton introduced at … Citeşte mai mult
