Ukufundisa mahhala, ucwaningo oluvulekile, kanye nokuxhaswa ngokucacile ukuxazulula izingozi zeplanethi yethu futhi sisize wonke umuntu ukuba afinyelele emhlabeni ongaphezulu kwayo.
Ilanga
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
You have just crossed 4.5 billion kilometres. 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.

Izilwandle eziphuza i-plastic, umoya ongabonakali, izilwandle ezinyuka ngamamilimitha ambalwa ngonyaka. Sichaza ucwaningo kanye namanombolo eduze kwazo.

Silandela indlela abantu, ukubhema kanye nezobuchwepheshe ezithinta ngayo into eplanethi yethu eyodwa.
Xhumanisa Isinqumo esiluhlazaNASA
Isishiyagalombili kumuntu olishumi uhlala ngaphansi kwelanga elikhanyayo, futhi omunye kumuntu wesithathu akakwazi ukubheka i-Milky Way kusuka ekhaya. Sizama ukuthola ilanga elimnyama futhi silandela ucwaningo lokukhula okunempilo.

Akukho akhawunti, akukho zindleko, akukho izikhangiso. Qala ngesilinganiso se-solar system, bese uqedela ukuhlela indiza eMars. Isifundo ngasinye sivela ezingeni eliphakeme, kusuka kokuqala kuya kwebanga le-university.

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. Uma isayithi likulethela okuthile, insizakalo isiza ukugcina izifundo, amathuluzi nocwaningo luvulekile ukuze ufunde kabanzi.
