Ndechipi chiri rutivi chairwo rwenheyo chaiyo yaEinstein yorudzi rwokuwirirana?
Context:Kusvikira makore anoverengeka gare gare apo Einstein akagadzira rondedzero yorudzi rwokuwirirana, iyo yakatanga nzvimbo-nguva yakakomberedzwa kuti ibatanidze giravhiti, kutaura kwokuti "rudzi rwokuwirirana chairwo" hakuna kushandiswa. Dzimwe nguva shanduro inoshandiswa inonzi "restricted relativity"; "special" chaizvoizvo inoreva "special case".[p 2][p 3][p 4][note 1] Mamwe emabasa aAlbert Einstein mu special relativity akavakirwa pamabasa ekare aHendrik Lorentz naHenri Poincaré. Dzidziso yacho yakava yakakwana zvikurukuru muna 1907.  Dzidziso iyi "yakakosha" pakuti inoshanda chete mune imwe nyaya apo nzvimbo-nguva "yakapfava", ndiko kuti, apo kukombama kwenzvimbo-nguva (mhedzisiro yesimba <unk> momentum tensor uye inomiririra giravhiti) haina basa. [chinyorwa 2] Kuti agone kukodzera giravhiti, Einstein akagadzira general relativity muna 1915. Kuwirirana chaiko, mukupesana nedzimwe rondedzero dzenhau, kunogamuchira kumhanyisa pamwe chete nokumhanyisa magadziriro enongedzero.
Chikamu "chakakosha" chedzidziso chaiyo yaEinstein yezvokufananidzira chinongedzera kwairi kuva nyaya chaiyo yeGeneral Theory of Relativity yake. Kuwirirana chaiko kunoshanda bedzi mumamiriro ezvinhu chaiwo apo kukombama kwenzvimbo-nguva kunoregeredzwa, i.e., nzvimbo-nguva "yakaenzana". Dzidziso yokuzvimiririra yakatangwa muna 1907, uye kuti ishandise zvakanaka simba rinokwevera zvinhu pasi, Einstein akatanga dzidziso yokuzvimiririra muna 1915.
