<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: Ukudlula: Ezinye izibikezelo ze - general relativity zihluke kakhulu kulezo ze - classical physics, ikakhulukazi ngokuphathelene nokudlula kwesikhathi, i - geometry yesikhala, ukunyakaza kwemizimba ekuweni kwamahhala, nokusakazeka kokukhanya. Izibonelo zalokhu kuhluka zihlanganisa ukunwetshwa kwesikhathi samandla adonsela phansi, i-gravitational lensing, i-gravitational redshift yokukhanya, kanye nokubambezeleka kwesikhathi samandla adonsela phansi. Izibikezelo ze-General Relativity ezihlobene ne-classical physics ziye zaqinisekiswa kukho konke ukubonwa nokuhlolwa kuze kube manje. Nakuba inkolelo-mbono evamile yokulinganisela ingeyona ukuphela kwenkolelo-mbono yokulinganisela yamandla adonsela phansi, iyinkolo elula kunazo zonke evumelana nemininingwane yokuhlola. Nokho, kusasele imibuzo engaphenduliwe, eyisisekelo kunazo zonke iwukuthi inkolelo-mbono evamile yokuthi izinto zihlobene ingahlanganiswa kanjani nemithetho ye-quantum physics ukuze kukhiqizwe inkolelo-mbono ephelele nevumelana ngokwayo ye-quantum gravity. Umbuzo: Izibikezelo ezithile zemfundiso ka - Einstein yokuhlobana okuvamile azivumelani naluphi uhlobo lwe - physics?  <response>: isayensi yemvelo yakudala
