U-Astronaut uDavid Scott wenza umbuliso ecaleni kweflegi yase-US ngoJulayi 30, 1971 enyangeni ngexesha le-Apollo 15 mission. (Ifoto: NASA / UNxibelelwano) Indawo engaqhelekanga yokuchonga efunyenwe yi Isixhobo saseKepler ithathe ingqalelo ye-SETI (Ukufuna Ubukrelekrele Basemhlabeni). Iziko kutshanje likhombe inkqubo ye-Allen Telescope Array yeekhilomitha ezingama-300 kumantla mpuma eSan Francisco kwinkwenkwezi, i-KIC 8462852, ukuvavanya ingcinga yokuba isiphoso sinokuba sisiginesha yempucuko yangaphandle.
Ukuba oku kuphuma ngaphandle inokuba lelona bali likhulu ukusukela oko kwasungulwa ivili okanye ukufunyanwa komlilo-kukweso sikalo, utshilo uGqr. UMichio Kaku kudliwanondlebe ngomnxeba noMbonisi. Ugqirha Kaku ngunjingalwazi we-physics kwiKholeji yesiXeko saseNew York (CUNY), apho abambe khona uSihlalo we-Henry Semat kunye noProfesa kwi-physics ye-theoretical. Elinye lawona manani adumileyo kwezenzululwazi namhlanje, uGqr. Kaku waseka i-String Field Theory, wabhala uninzi INew York Times ethengisa ngokugqibelele iincwadi , kwaye iyaqhubeka nokulandela kuka-Albert Einstein ekuyileni ithiyori kuyo yonke into .
Sinekratshi lokucinga ukuba sinomdla kakhulu, izidalwa zasemhlabeni ziya kuhamba amawaka eminyaka yokukhanya nje ukusindwendwela. Asinomdla nje.
Okanye inokuba yeyona dud inkulu ukusukela kwiLoch Ness monster, kunye nantoni na phakathi. UCarl Sagan wakhe wathi, ‘Amabango amangalisayo afuna ubungqina obungummangaliso.’ Ke ukuba luphawu lwendawo engaphandle komhlaba, kufuneka sikwazi ukubona ukuba yintoni le nto. Omnye umgqatswa bubungqina bayo bohlobo-2 lwempucuko. Siyi-zero zero; amandla ethu siwafumana kwizityalo ezifileyo, kwi-oyile nakwamalahle. Uhlobo lwe-1 yiplanethi; banokulawula imozulu, banokulawula iplanethi iphela. Uhlobo lwe-2 yi-stellar, balawula iinkwenkwezi ezinje nge Star Trek. Uhlobo lwe-3 yi-galactic njenge-Star Wars. Amandla afunekayo okulahla ukukhanya kweenkwenkwezi ngeepesenti ezingama-22 angakufanelekela oku njengohlobo lwempucuko yesi-2-oko kukuthi, banokudlala ngeenkwenkwezi-nangona kunjalo kukuqagela njengoko singazi ukuba sisiginitsha yempucuko yasemhlabeni na okanye ukuleqa irhanisi lasendle. Asazi.
Ithuba lokuba isenokuba ngumtyikityo wenye impucuko liphakamise enye ingxoxo ngobunyani be UFermi Paradox . IFermi Paradox izama ukucacisa ukuba kutheni kubonakala ngathi sisodwa kwindalo iphela. Ingcali yamachiza u-Enrico Fermi wayekholelwa kwelokuba ukuba bekukho imibutho yabaphambukeli, enye yazo ibinokuthambisa ngokulula imithala ngexesha lesigidi seminyaka. Isikali sexesha lokuthambisa iigalaxi yimigca encinci xa kuthelekiswa nobudala bendalo iphela, ke ukuba ikho ikhona ngesele siyibonile imiqondiso yayo.
Abanye abantu bathi ukuba kukho iindlela zobomi ezikrelekrele phaya, kwaye ndicinga ukuba zikhona, Kwenzeka njani ukuba bangasindwendweli? Kutheni le nto bengahlali emhlabeni wengca ye-White House, babhengeze ubukho babo kwaye basinike itekhnoloji yabo? Ewe, ukuba uhamba ezantsi kwindlela yelizwe kwaye ubona indlwana, uyehla uye kwiimbovane uthi ndikuphathele izipho, ndikuphathela iitrinket, ubuhlalu, ndikuphathele amandla enyukliya, ndise kwindlovukazi yakho yembovane ? Okanye ngaba sinomdla ongaqhelekanga wokunyathela ezimbalwa zazo? Ukuba abaphambukeli bahambele phambili kangangokuba banokuhlala kwibala laseWhite House, ke sifana neembovane kubo, asinanto sibanikayo, ke isizathu sokuba bangabhengezi ubukho babo kuthi kukuba siyadika , Bazibonile zonke. Asinanto sinika ngayo impucuko ehambele phambili kwaye yiyo loo nto ndicinga ukuba abasindwendweli. Sinekratshi lokucinga ukuba sinomdla kakhulu, izidalwa zasemhlabeni ziya kuhamba amawaka eminyaka yokukhanya nje ukusindwendwela. Kungenxa yoko le nto bengasindwendweli, singekho mdla nje.
Ukudanisa kunye neenkwenkwezi: uNeil deGrasse Tyson ngesizathu sokuba iSayensi 'i-Hilarious.'
