Uyini njalo okudonsa, njengoba ibalwa kanye lesi silinganiso isetshenziswa lapho

Njengoba omunye eziningi eziyisisekelo eziseZwini physics, njalo okudonsa kukhulunywa ngaye okokuqala ekhulwini le-18. Ngesikhathi esifanayo sayiswa imizamo yokuqala ukukala ukubaluleka kwayo, kodwa ngenxa ukungapheleli ithuluzi futhi ngenxa yokuswela ulwazi kulo mkhakha, enze kube nokwenzeka kuphela nekhulu le-19. Kamuva lo mphumela ngokuphindaphindiwe kushintshwe (okokugcina lokhu kwenziwe 2013). Nokho, kufanele kuphawulwe ukuthi umehluko oyinhloko phakathi lokuqala (G = 6,67428 (67) · 10 ^-11 s ^-2 · m³ · kg ^-1 noma H · m² · ^-2 kg) nowokugcina (G = 6,67384 ( 80) · 10 ^-11 s ^-2 · m³ · kg ^-1 noma H · m² · kg ^-2) amagugu alikho.

Ukusebenzisa le isici ngoba izinjongo ezifanele, ukuze kuqondwe ukuthi lokhu njalo ngokuya jikelele komhlaba wonke (uma kungekhona ukwenza ukubhuka e aphansi kuyizinhlayiyana physics kanye nezinye isayensi abangaphansi eyaziwa). Lokhu kusho ukuthi njalo okudonsa Zomhlaba, Moon noma Mars, ngeke ihluke nomunye.

Lokhu inani njalo okuyisisekelo Mechanics classical. Ngakho-ke, njalo okudonsa ehilelekile ezihlukahlukene izibalo. Ikakhulukazi, ngaphandle kokuba ulwazi mayelana ucishe ukubaluleka ngqo sale ipharamitha, abacwaningi ayikwazanga ukubala esibaluleke kangaka embonini isikhala, ukusheshisa mahhala ukuwa (okuzoba yabo nganoma iyiphi iplanethi noma ezinye nendikimba ethile esemkhathini).

Nokho Newton, ezashiwo umthetho wamandla adonsela phansi ngendlela jikelele, njalo okudonsa wayaziwa kuphela theory. Okungukuthi, wakwazi ukwakha omunye postulates ezibaluleke kakhulu ngokomzimba, ngaphandle kokuba ulwazi mayelana isamba kulo, eqinisweni, kusekelwe.

Ngokungafani nezinye constants ayisisekelo, mayelana nokuthi iyiphi njalo okudonsa, i-physics athi nabanye nokwabelana ukunemba. Inani layo eyatholakala futhi ngezikhathi ezithile, futhi isikhathi ngasinye lihlukile kulowo odlule. ososayensi abaningi bakholelwa ukuthi leli qiniso ongakaphathelani iguquka, kodwa isizathu ewubala nje ngaphezulu. Okokuqala, lokhu nesilinganiso (ekubaleni lokhu njalo Kwenziwa ucwaningo ehlukahlukene), kanti okwesibili, amadivaysi ngokunembile, okuyinto kancane kancane kwandisa, idatha kokuba esibekiwe, futhi umphumela omusha eyatholakala.

Sikhishwe iqiniso lokuthi njalo okudonsa liyinani kulinganiswa 10 kuya -11 degrees (leso sika-Mechanics classical ukubaluleka ultrasmall), akumangalisi intuthuko njalo Coefficient. Lapho okungukuthi kuncike uphawu ukulungiswa eziqala 14 zedesimali.

Nokho, kukhona zanamuhla wave physics omunye umbono, okuyinto ukubeka phambili Fred Hoyle noJohane. Narlikar ku 70-yalolucwaningo kwekhulu elidlule. Ngokusho ezizathwini zabo, njalo okudonsa incipha nge sikhathi, esithinta nezinye izinkomba eziningi ezibhekwa constants. Ngakho, i-American sezinkanyezi van Flandern kwaphawulwa lo mkhuba ukusheshisa kancane of the Moon nezinye izindikimba zasezulwini. Báqondiswa lo mbono, kufanele bazitshela ukuthi noma yimaphi amaphutha wonke esikhathini izibalo ngaphambili akazange ashade, futhi umehluko imiphumela kungenxa izinguquko njalo kule ukubaluleka uqobo. Lo mbono efanayo ithi mayelana impermanence ezinye eziguquguqukayo ezifana ngejubane lokukhanya e cleaner.
