<prompt> U-Einstein wasungula indlela yokucabanga ebizwa ngokuthi i-a? Njengoba kunikezwe umbuzo odlule, bhala umongo onempendulo yawo. Kungaba imisho engu-1 kuya kwengu-20. Umongo:  <response>: Kwakungumjikelezo weplanethi iMercury kuphela okwakubonakala sengathi umthetho kaNewton wokudonsela phansi wawungawuchazi ngokugcwele. Ezinye izazi zezinto ezisemkhathini zazibikezela ukuba khona kwenye iplanethi iVulcan eyayingachaza ukungafani; kodwa, naphezu kwezinye izinkomba zokuqala, ayikho iplanethi enjalo eyatholwa. Lapho uAlbert Einstein esungula inkolelo-mbono yakhe yokuhlobana okuvamile GR waphendulela ukunakekela kwakhe enkingeni yomjikelezo kaMercury futhi wathola ukuthi inkolelo-mbono yakhe yengeza ukulungiswa, okwakungachaza ukungafani. Lesi kwakuyisikhathi sokuqala lapho kwaboniswa khona ukuthi iNewtons Theory of Gravity ayilungile kangako kunenye indlela.
