<prompt> I-General Relativity GR, eyaziwa nangokuthi i-General Theory of Relativity noma i-GTR iyinkolelo-mbono ye-geometric yokudonsela phansi eyashicilelwa ngu-Albert Einstein ngo-1915 futhi incazelo yamanje yokudonsela phansi kwe-physics yanamuhla. I-General Relativity ihlanganisa i-special relativity futhi ithatha indawo yomthetho kaNewton wokudonsela phansi kwendawo yonke, ihlinzeka incazelo ehlanganisiwe yokudonsela phansi njengepropathi ye-geometric yesikhala nesikhathi, noma isikhala-isikhathi. Ikakhulukazi, ukugoba kwesikhala-isikhathi kuhlobene ngqo namandla nomfutho wanoma iyiphi into nemisebe ekhona. Ubudlelwano bucaciswa yi-Einstein equations, uhlelo lwe-particle differential equations. Umbuzo: Luhlobo luni lwenkolelo-mbono ejwayelekile?  <response>: imfundiso yokwakheka
