<prompt> Muzvinyorwa zveGeneral Relativity, hapana chinhu chemuviri chinogona kubata kana kukunda chiedza. Hapana chinobva pachiitiko A chinogona kusvika kune imwe nzvimbo X pamberi pechiedza chakatumirwa paA kuenda kuX. Nekuda kweizvozvo, kuongororwa kwemitsetse yese yechiedza null geodesics kunopa ruzivo rwakakosha nezve chimiro chenguva yenguva. Chimiro ichi chinogona kuratidzwa uchishandisa Penrose Carter madhayagiramu umo nzvimbo dzisingaverengeke uye nguva dzisingaverengeke dzakapfupikiswa compactified kuitira kuti dzikwane pamepu yakapera, nepo mwenje uchiri kufamba pamwe ne diagonals senge mune yakajairwa nzvimbo-nguva madhayagiramu. Kuziva kukosha kwechimiro checausal, Roger Penrose nevamwe vakagadzira izvo zvinozivikanwa seGlobal geometry. MuGlobal geometry, chidzidzo chechinhu hachisi chimwe kana imwe yemhuri yeEinsteins equations mhinduro.  <response>: A kusvika kuX
