A key concept in special relativity is that time and space are not independent but depend on the relative motion state of the observer. This also includes the idea that relative velocity affects how time and distances between objects are measured. Later, in 1915, Einstein developed general relativity to extend the theory to include the effects of gravity, showing that matter or energy can determine the geometry of spacetime, affecting the motion of bodies and systems in curved spacetime. Additionally, the spacetime structure imposes on matter to position and behave according to its curvature. Then, we examined Einstein's equation and Schwarzschild's solution, which predicted the existence of black holes due to uncertainties in these solutions. We then conducted a thermodynamic study of the Schwarzschild black hole based on classical laws of thermodynamics, calculating some thermodynamic quantities of the black hole, and studying the variations of these quantities in relation to each other by plotting, analyzing, and interpreting the data. 2024-07-14T00:00:00Z Vibrations, Waves and Optics Dr. BOUHDJER, Lazhar http://dspace.univ-bouira.dz:8080/jspui/handle/123456789/17474 2024-12-08T13:38:16Z 2024-01-01T00:00:00Z Titre: Vibrations, Waves and Optics Auteur(s): Dr. BOUHDJER, Lazhar Résumé: ph 2024-01-01T00:00:00Z Cours de Mécanique Quantique II Bouchemla, Nedjma http://dspace.univ-bouira.dz:8080/jspui/handle/123456789/15960 2024-01-30T08:42:03Z 2022-01-01T00:00:00Z Titre: Cours de Mécanique Quantique II Auteur(s): Bouchemla, Nedjma 2022-01-01T00:00:00Z Synthèse Des Activités De Recherche HAMMA, Issam http://dspace.univ-bouira.dz:8080/jspui/handle/123456789/15918 2024-01-25T09:48:41Z 2020-01-01T00:00:00Z Titre: Synthèse Des Activités De Recherche Auteur(s): HAMMA, Issam 2020-01-01T00:00:00Z
