I-1 APR esinye isigaba eside socwaningo okuhloswe ngaso ukuthola nokufunda amaza adonsela phansi. Futhi manje, ngemva kwenyanga, ukubonwa okuphumelelayo kokuqala kwamenyezelwa njengengxenye yalesi sigaba somsebenzi.
I-LIGO (Laser Interferometer Gravitational-Wave Observatory) kanye nama-Virgo observatories asetshenziselwa ukuthola amagagasi adonsela phansi. Eyokuqala ihlanganisa izakhiwo ezimbili ezitholakala e-United States e-Livingston (Louisiana) naseHanford (Washington). Ngokulandelayo, umtshina we-Virgo use-European Gravity Observatory (EGO).
Ngakho-ke, kubikwa ukuthi ekupheleni kuka-April kwakungenzeka ukubhalisa amasignali amabili adonsela phansi ngesikhathi esisodwa. Eyokuqala yaqoshwa ngo-Ephreli 25. Umthombo wayo, ngokusho kwedatha yokuqala, kwakuyinhlekelele yendawo yonke - ukuhlanganiswa kwezinkanyezi ezimbili ze-neutron. Ubuningi bezinto ezinjalo buqhathaniswa nesisindo seLanga, kodwa i-radius ingamakhilomitha angu-10-20 kuphela. Umthombo wesignali wawusebangeni elingaba iminyaka yokukhanya eyizigidi ezingu-500 ukusuka kithi.
Umcimbi wesibili uqoshwe ngo-Ephreli 26. Ososayensi bakholelwa ukuthi kulokhu amagagasi adonsela phansi azalwa ngenxa yokushayisana kwenkanyezi ye-neutron kanye nomgodi omnyama ebangeni elingama-light years ayizigidi eziyizinkulungwane ezingu-1,2 ukusuka eMhlabeni.
Qaphela ukuthi ukutholwa kokuqala kwamagagasi adonsela phansi kwamenyezelwa ngoFebhuwari 11, 2016 - umthombo wawo kwaba ukuhlanganiswa kwezimbobo ezimbili ezimnyama. Futhi ngo-2017, ososayensi baqale babona amaza adonsela phansi kusukela ekuhlanganisweni kwezinkanyezi ezimbili ze-neutron.
