El indawo yonke ebonakalayo Yingxenye yendawo yonke esingayithola futhi siyifunde eMhlabeni noma ngezinsimbi zasemkhathini. Kubhekiselwa esikhaleni esingaphakathi “komkhathi obonakalayo” wethu, okuwuhlobo lomkhawulo esingakwazi ukubona izinto noma izehlakalo ngenxa yejubane elinomkhawulo lokukhanya kanye nokwanda kwendawo yonke. Njengoba isayensi ithuthuka, sithola okwengeziwe ngendawo yonke.
Kulesi sihloko sizokutshela konke okudingeka ukwazi ngendawo yonke ebonakalayo, izici zayo nokuthi ziyini izingxenye zendawo yonke.
Uyini umkhathi obonakalayo
Ngamagama alula, umkhathi obonakalayo ufana nebhamuza elikhulayo elisuka endaweni yethu yokubuka eMhlabeni. Ukukhanya kuhamba ngesivinini esilinganiselwe, futhi lokhu kusho ukuthi ulwazi olumayelana nezinto nezenzakalo ezisemkhathini lungafinyelela kithi kuphela uma luye lwaba nesikhathi esanele sokuya kithi lusuka emthonjeni walo. Njengoba indawo yonke ikhula, ezinye izifunda zisuka kithi ngesivinini esidlula ijubane lokukhanya, okusho ukuthi ngeke sithole ukwaziswa okuvela kuzo.
Ubukhulu bomkhathi obonakalayo bushintsha njalo njengoba ukwanda kwendawo yonke kuqhubeka. Njengamanje, kulinganiselwa ukuthi irediyasi yebhamuza lethu elibonakalayo Cishe ku-46 billion light years, okusho ukuthi singathola kuphela izinto noma izehlakalo ezingalelo banga noma eziseduze nathi ngaleso sikhathi.
Izingxenye zomkhathi obonakalayo
Izinhlobo ezihlukahlukene zezimo zemvelo ezakha ukwakheka kwendawo yonke ebonakalayo zaziwa kangcono njengezinto zezinkanyezi noma izindikimba zasemkhathini. Lezi zinhlangano, ezibonakala ngeso lenyama noma ngokusebenzisa izinto zokubuka, ziyizingxenye eziyisisekelo zendawo yonke.
Umkhathi omkhulu womkhathi awunakulinganiswa, unobubanzi obungenamkhawulo bendawo engenalutho ephazanyiswa ukunqwabelana okukhulu kwezinto namandla. Ukwakheka nokuguquguquka kwalokhu kunqwabelana kunquma ukwakheka kwezinto ezihlukahlukene zezinkanyezi.
Udaba olumnyama luwuhlobo lwendaba olungatholakali kalula oluhlala lungabonakali ekubukweni njengoba lungakhiphi noma yimiphi imisebe kazibuthe. Nokho, Yakha ingxenye ebalulekile yendaba endaweni yonke ku-26,8%.
Amandla amnyama uhlobo lwamandla olubonakala ngokungaqondile, ukuminyana okungaguquki, nokungakwazi ukubonwa. Umsebenzi wawo oyinhloko ukushayela indawo yonke ekukhuliseni. Nakuba ubukhona bayo bamanje buseyindaba yethiyori ye-cosmological, Kukholakala ukuthi afinyelela ku-70% wamandla endaweni yonke akhiwe yilolu hlobo lwamandla.
Imithala nezinkanyezi
Umthala iqoqo lezinkanyezi ezizungeza i-eksisi eyabiwe, ziletha nezinye izakhi zomzimba ezahlukahlukene, okuhlanganisa amaplanethi, izinkanyezi ezinomsila, ama-asteroids, namafu amakhulu e-hydrogen ne-helium, ngokuvamile aziwa ngokuthi ama-nebulae.
AmaNebula anesibopho sokubukeka okumhlophe okujwayelekile kwemithala, okuhlanganisa ne-Milky Way, lapho isimiso sethu sonozungezilanga sihlala khona. Igama lalo mthala livela ekufaneni kwalo nobisi oluchithekile, ukubukeka okunjengomfudlana amaGreki asendulo ayehlotshaniswa nobisi lwebele lukankulunkulukazi uHera (owaziwa ngokuthi uJuno kumaRoma) ezinganekwaneni zawo zezinganekwane.
Izinkanyezi zingamalanga akude, ngayinye inezici nezici zayo ezihlukile. Lezi zindikimba zasemkhathini zingabhekwa njengokuqhuma okukhulu okuqhubekayo emkhathini okugcina isimo esiyindilinga ngenxa yamandla adonsela phansi azo, anamandla anele okuvimbela izakhi zazo ukuba zingahlakazeki endaweni yonke. ILanga yisibonelo esibonakala kakhulu senkanyezi.
Amaplanethi namasathelayithi
Iplanethi yinto engabonakali, eyindilinga esemkhathini ezungeza enye inkanyezi, ngokuvamile enkulu kakhulu, egudle umzila oyingqayizivele we-orbital ongenawo amanye amaplanethi noma amaplanethi. Njengoba iplanethi ngayinye yakha isuka emafini akhona amagesi kanye nemfucumfucu ye-cosmic, ukwakheka kwawo kanye nezimfanelo kungahluka kakhulu komunye nomunye. Lo mehluko uncike kakhulu ekuba seduze kweplanethi noma ebangeni lenkanyezi. Ngokwesibonelo, Umkhathi weplanethi iMercury wakhiwe ngamagesi akhanyayo namancane ngenxa yokuba seduze neLanga., kuyilapho umkhathi we-Jupiter, oqhele ngezigidi zamakhilomitha, uminyene futhi wakhiwe amagesi emvelo asinda kakhulu njenge-ethane, i-methane ne-ammonia, ngaphezu kwe-hydrogen ne-helium.
Into yasezulwini ezungeza iplanethi enkulu futhi ibanjwe amandla ayo adonsela phansi ibizwa ngokuthi isathelayithi yemvelo. Lawa masathelayithi angahluka kakhulu ngosayizi, ukwakheka kanye nokubunjwa, kusukela ezindikimbeni zasemkhathini eziyisiyingi njengeNyanga yethu kuye kumasathelayithi anomumo ongavamile njenge-Deimos, okungenye yamasathelayithi amakhulukazi e-Mars.
Amasathelayithi, kungakhathaliseki ukuthi amunye njengoMhlaba noma ubuningi njengeJupiter's 92, Zinemizila yazo ezungeza iplanethi. Nokho, nazo zihamba ngokuhlanganyela neplanethi njengoba izungeza inkanyezi. Kubalulekile ukukhumbula ukuthi amasathelayithi awafani nezindandatho zamaplanethi. Izindandatho zeplanethi zakha kusuka ezinhlayiyeni, uthuli namagesi azungeza ndawonye ezungeza iplanethi, enze idiski elibonakalayo elifanayo, njengoba kubonakala kuSaturn.
Amaplanethi namaplanethi
Ama-asteroids amancane, izindikimba zasezulwini ezinamadwala ezincane kakhulu ukuthi zingahlukaniswa njengamaplanethi, kodwa zikhulu kakhulu ukuthi zingahlukaniswa njengama-meteoroids. Bangatholakala behlakazekile, kungaba uwedwa noma ngamaqembu aziwa ngokuthi amasimu asteroid, okungama-agglomerations aminyene kakhulu. Lezi zingcezu zento ziyahlukahluka ngobukhulu nokuma, ngokuvamile zinesimo esingajwayelekile. Esimisweni sonozungezilanga kunebhande le-asteroid eliphakathi kwemizila yeMars neJupiter. Ngokuyisisekelo, ama-asteroid awalutho ngaphandle kwamadwala asemkhathini angenawo umkhathi noma impendulo kumkhakha wawo wamandla adonsela phansi. Nakuba amanye ama-asteroid ahlala ezinzile ngaphakathi kwenkundla noma ibhande, amanye ahamba emigudwini eshintshashintshayo ezungeze inkanyezi, ngakho angabangela imithelela yenkanyezi eyinhlekelele.
Inkanyezi enomsila iyindikimba yasezulwini ehamba emkhathini, Ngokuvamile kwenziwa izinhlayiya zeqhwa, amadwala nothuli. Njengoba isondela enkanyezini eshisayo njengeLanga, inkanyezi enomsila iqala ukuhwamuka, ishiya umzila owaziwayo obizwa ngokuthi umsila.
Ngithemba ukuthi ngalolu lwazi ungafunda okwengeziwe ngomkhathi obonakalayo nezici zawo.
