Işığın Kütlesi Yoksa Yerçekimi Işığı Neden BÜKÜYOR? - Feynman'ın Açıklaması | Richard Feynman

In this video, unlike other videos on my channel, we explore in an original way how light, despite having no mass, can be bent by gravity, why Newton's classical model of gravity is insufficient, and the revolutionary spacetime geometry in Einstein's general theory of relativity. Starting with the principle of equivalence, we examine step-by-step how mass and energy bend spacetime, and how light follows the straightest path (geodesy) within this curved geometry. We explore that fascinating process, from Eddington's historic observation of a solar eclipse to the gravitational lensing method and the Shapiro delay. We delve not only into the mechanism of light bending, but also into why light carries energy and momentum even without mass, how Eddington's 1919 experiment brought Einstein global fame, and how gravitational lenses are used in modern astronomy to map invisible dark matter. #light #gravity #alberteinstein #physics #relativity #spacetime #feynmanlectures #cosmology #feynman #science #photon #richardfeynman
