Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna 1984, Herb Chen weUniversity of California paIrvine ndiye akatanga kutaura zvakanakira kushandisa mvura inorema senzira yokuona nayo neutrinos dzinobva kuzuva. Kusiyana nezvakamboshandiswa kare, kushandisa mvura inorema kwaizoita kuti detector iyi inzwe zvinhu zviviri, chimwe chacho ndechokuziva zvose zvinonzi neutrinos, uye chimwe chacho ndechokuziva neutrinos dzemaerekitironi chete. Nokudaro, mucherechedzi wakadaro unogona kuyera kudengenyeka kwe neutrino zvakananga. Nzvimbo iri muCanada yainakidza nokuti Atomic Energy of Canada Limited, iyo inochengetedza matura makuru emvura inorema kutsigira CANDU reactor power plants, yakanga yakagadzirira kukweretesa mari inodiwa (inokosha C$330,000,000 pamitengo yemusika) pasina mari. Creighton Mine muSudbury, pakati pevakadzika zvikuru munyika uye nokudaro yakaderera mumhepo yakasviba, yakakurumidza kuzivikanwa senzvimbo yakanaka yekuedza kwaChen kwakanga kwava kuda kuvakwa, uye kutungamira kwemugodhi kwakanga kuri kuda kuita kuti nzvimbo yacho iwanike nokuda kwezvimwe zvinodhura chete. Panguva iyoyo yakakwikwidzana neTRIUMF's KAON Factory chikumbiro chemari yemubatanidzwa, uye huwandu hwakawanda hwemakoroji anotsigira SNO nekukurumidza yakatungamira kuti isarudzwe kusimudzira. Chibvumirano chepamutemo chakapiwa muna 1990.  Mubvunzo: Chii chiri kuyerwa?
