Ulwazi olukhululekile njengelanga le-star, leplanethi yethu ehlukanisiwe kanye nalowo wonke umuntu obheka phambili ezweni elingaphandle kwalo.
Phambi kokuba sihambe, bheka lapho ukhona. Uhlala endaweni encane, itshe elimanzi, lijikeleza ngokushesha kunesandi futhi liwela njalo ngasohlangothini lwesibhakabhaka esijwayelekile. Insimbi emlonyeni wakho ne-calcium emithambo yakho yakhiwa ezibhakabhaka ezifa ngaphambi kokuthi ilanga lizalwa. Ngomuzwa sizondiza ngaphandle, ngesilinganiso sangempela, sidlula emhlabeni ohlanganisa ukukhanya kwethu. Ingxenye enkulu yesikhathi sokuhamba yimpi; lokho kuyinto. Khumbula inkinobho ensundu emnyama emuva kwakho. Yindawo eyodwa kuphela esiyazi lapho umuntu abheke khona futhi ebuza ukuthi kwenzekani.
Ilanga
Konke kuqala lapha. Ilanga ligcina i-99.86% yesisindo sonke se-solar system: i-fusion reactor ebanzi ngamaplanethi angama-109.

Konke kuqala lapha. Ilanga ligcina i-99.86% yesisindo sonke se-solar system: i-fusion reactor ebanzi ngamaplanethi angama-109.
Kusuka elanga: 0 AU · Ukukhanya kwelanga kuthatha: 0 s · 5,499 °C
Unyaka lapha uhlala izinsuku ezingama-88, kodwa ukuvuka kwelanga kuya kokunye kuthatha amahora angama-176. Iplanethi ehamba ngokushesha kakhulu inezinsuku ezihamba kancane kakhulu.
Kusuka elanga: 0.4 AU · Ukukhanya kwelanga kuthatha: 3.2 min · Usuku olulodwa luhlala: 4,222.6 h · 167 °C
Akunakude kakhulu noMhlaba, kodwa kubanda kakhulu. Ikhaya le-greenhouse elihambayo ligcina iplanethi e-464 °C, lipholile ngokwanele ukuxuba uphethiloli.
Kusuka elanga: 0.7 AU · Ukukhanya kwelanga kuthatha: 6 min · Usuku olulodwa luhlala: 2,802 h · 464 °C
I-palette blue dot, futhi indawo ekuphela kwayo esiyazi lapho umuntu esebuza khona imibuzo. Inkinga ngayinye esisebenza kuyo ihlala lapha.
Kusuka elanga: 1 AU · Ukukhanya kwelanga kuthatha: 8.3 min · Usuku olulodwa luhlala: 24 h · 15 °C
Isigamu sesisindo sezulu, nelanga eliphuma lishintsha umbala. Izwe elisha abantu abazohamba kulo.
Kusuka elanga: 1.5 AU · Ukukhanya kwelanga kuthatha: 12.7 min · Usuku olulodwa luhlala: 24.7 h · -65 °C
Kungaphezu kwephindwe kabili inani lezinkanyezi zonke ezihlangene. I-Great Red Spot iyisimo sezulu esibanzi kunaso iplanethi.
Kusuka elanga: 5.2 AU · Ukukhanya kwelanga kuthatha: 43.3 min · Usuku olulodwa luhlala: 9.9 h · -110 °C
Izinhlamvu zibanzi kunamakhilomitha angama-270,000 futhi, ezindlini, ziyimitha eziyisithupha ubude. ISaturn ayinzima kakhulu kunemanzi.
Kusuka elanga: 9.5 AU · Ukukhanya kwelanga kuthatha: 1 h 19 min · Usuku olulodwa luhlala: 10.7 h · -140 °C
Igobile kumadigri angama-98, ijikeleza ilanga. Umcibisholo ngamunye uthola iminyaka engu-42 yokukhanya kwelanga, bese ku-42 yebusuku.
Kusuka elanga: 19.2 AU · Ukukhanya kwelanga kuthatha: 2 h 40 min · Usuku olulodwa luhlala: 17.2 h · -195 °C
Umoya ofinyelela ku-2,000 km/h, okhawulelwe kakhulu ehlelo lokukhanya. Kusuka lapha ilanga liyisinkanyezi esikhanyayo kuphela esimweni sezulu esimnyama.
Kusuka elanga: 30.1 AU · Ukukhanya kwelanga kuthatha: 4 h 10 min · Usuku olulodwa luhlala: 16.1 h · -200 °C
Udlule 4.5 amakhilomitha ayizigidi. Sunlight makes the same journey in about four hours, and it has been making it for four and a half billion years.
Funda ukuthi ama-orbit asebenza kanjaniInkinga ngayinye emhlabeni, engqondweni, yinkinga yolwazi. Sichaza isifundo esibhekene nezingozi ezikhona ekhaya lethu kuphela, sifundisa isayensi yezulu kubo bonke ababheka phambili, futhi sixhasa konke okuvulekile. Akukho lutho olukhokhelwayo. Akukho abanikazi bezimali. Ukucabanga nje, okuhloswe ngawo unyaka ozayo.
Indlela ezine zokuzivikela kweplanethi encane: ama-oceans ayo negesi, amandla alo, ubuhle bezimpilo eziphilayo kuyo, kanye negumbi lokufundela elivulekile labo bonke abafuna ukufinyelela ngaphezu kwayo.
Izifundo kanye nezisetshenziswa ezixhumeneyo ezishintsha wonke umuntu ube ngumfundi oqonda ama-orbit, ama-rockets nesimo sezulu. Simahhala, isikhathi eside.

Ngomlando wonke womuntu, umuntu angabheka phezulu futhi athole i-Milky Way. Namhlanje umuntu oyedwa kuthathu akakwazi ukuyibona, futhi oyisishiyagalombili kumashumi amabili abaphila ngaphansi kwezulu elingasekho ngokucacile. Ukwelashwa kuyinto elula: ukuvikela ukukhanya, ukuwuthambisa, futhi uvumele ubusuku bubuye lapho akukho muntu ofuna khona.

Gcina isifundo, hlola i-physics, kwakha ithuluzi, hlela umkhosi wezulu olumnyama. Yonke inkontileka ishicilelwe, futhi abahlinzeki abajwayelekile bangaba amalungu e DAO.
Thola umsebenziKonke lapha mahhala, futhi kuzohlala njalo. Kusuka ngo-2017 abasunguli bathathe le phrojekthi ngokwabo, ngenxa yenjabulo elula yokubonisa abantu izulu esilubelana ngayo. Uma iwebhusayithi ikunikeza okuthile, insizakalo isiza ukugcina izifundo, amathuluzi nocwaningo luvulekile ukuze ufunde okuningi.
