Unogona kugadzira mitsetse miviri yechinyorwa ichi here?
Context:Mufizikisi, giravhiti (kubva muchiLatin gravitas 'uremu') ndiko kudyidzana kukuru kunokonzera kukwezva pakati pezvinhu zvose zvine uremu kana simba. Simba rinokweva ndiro, nokure, risina simba zvikuru pamasimba mana anokosha, rinenge risina simba kakapetwa ka1038 pane simba rakasimba, kakapetwa ka1036 pane simba remagetsi uye kakapetwa ka1029 pane simba risina simba. Somugumisiro, haina pesvedzero inokosha pamwero wezvikamu zviduku zveatomu. Zvisinei, simba rinokwevera zvinhu pasi ndiro rinoita kuti zvinhu zvifambirane, uye ndiro rinoita kuti mapuraneti, nyeredzi, mapoka enyeredzi, uye kunyange chiedza zvifambe.  Pasi pano, simba rinokwevera zvinhu pasi rinoita kuti zvinhu zvive nehuremu, uye simba rinokwevera zvinhu pasi reMwedzi ndiro rinoita kuti pave nemvura inoyerera mumakungwa (kuyerera kwemvura kunokonzerwa nekutenderera kweNyika neMwedzi). Giravhiti inewo mabasa akawanda anokosha muzvipenyu, ichibetsera kutungamirira kukura kwezvirimwa kupfurikidza nomutoo wegravitropism uye ichipesvedzera kutenderera kwemvura muzvinhu zvipenyu zvine masero akawanda. Kunzvera migumisiro yokusava nehuremu kwakaratidza kuti simba rinokweva zvinhu pasi ringaita basa rinokosha pakuita kuti muviri usadzivirirwe uye kuti masero arambe achisiyana-siyana mumuviri womunhu.  Kukwezvana kwaiita zvinhu zvaiva negasi zvakasikwa kwakabvumira kuti zvibatanidzane zvobva zvaumba nyeredzi idzo dzakazopedzisira dzaumba mapoka enyeredzi, saka simba rinokwevera zvinhu pasi ndiro rakaita kuti pave nezvinhu zvakawanda zvakakura zviri muchadenga. Giravhiti ine nzvimbo isingaperi, kunyange zvazvo migumisiro yayo ichiva isina simba zvikuru sezvo zvinhu zvinoenda kure zvikuru.  Giravhiti inonyatsorondedzerwa neGeneral Theory of Relativity (yakatsanangurwa naAlbert Einstein muna 1915), iyo inorondedzera giravhiti kwete sesimba, asi sekukombama kwenzvimbo-nguva, kunokonzerwa nekugoverwa kusingaenzaniswi kwehuremu, uye kukonzera kuti huwandu hufambe nemitsetse ye geodesic. Muenzaniso wakanyanyisa wekukombama kweiyo nzvimbo-nguva igomba dema, kubva pasina chinhu - kunyangwe chiedza - chinogona kupukunyuka kana chakapfuura gomba dema. Zvisinei, kune akawanda mashandisirwo, giravhiti inosvika zvakanaka nemutemo waNewton wekukweva kwepasirese, uyo unotsanangura giravhiti sesimba rinokonzeresa chero miviri miviri kukwezverwa kune mumwe nemumwe, ine hukuru hwakaenzana neyakagadzirwa yemasa avo uye inopesana neyakaenzana nekwere yenzvimbo iri pakati pavo.
Mune dzidziso huru yefizikisi (Newton), Gravity kukwezvana pakati pezvinhu kwakavakirwa pahuremu hwazvo nechikamu chechikamu chinovaparadzanisa. Muzvinyorwa zve relativity (Einstein), ndiko kukombama kwenzvimbo-nguva kunogadzirwa nezvinhu pachazvo.
