Anomalii ale relativității generale
Rezumat 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 energetice nu sunt foarte eficiente. Sunt necesare ipoteze mai detaliate asupra conținutului materiei. Mulți oameni de știință și filosofi au ajuns la concluzia că singularitățile trebuie să fie asociate cu atingerea limitelor valabilității fizice a relativității generale, fiind nevoie … Citeşte mai mult
