Kanye njengokuba yonke into inesiqalo, ikwanayo nokutshona kwelanga. Isiseko esinjalo sisetyenziselwa ubukho bunjalo, ukusuka kubomi ngokwabo ukuya kwinto nganye eyinxalenye yendalo iphela. Ngaloo ndlela, amaxesha amaninzi Kuyinto eqhelekileyo ukuzibuza ukuba kuya kuba nini ukuphela kwayo yonke into kwaye ukuba inzululwazi iya kuba nempendulo. Kodwa, ngokubanzi, zithini izazi ngeenkwenkwezi malunga nesiphelo soMhlaba?
Ungakhathazeki, ngokuqinisekileyo ukuphela kwexesha kusekude kakhulu. Ngokutsho koluntu lwenzululwazi, kwixesha eliphakathi okanye elide, akukho bungqina bezoyikiso zangempela ze-cosmic. Nangona kunjalo, ikamva aliqinisekanga kwaye alinakuphikiswa, ngoko yonke into inokwenzeka.
Unokuba nomdla kwinqaku lethu: Ngaba ungathanda ukwazi ukuba yintoni amafu? Bazi kakuhle!
Isiphelo soMhlaba. Kutheni le nto ixhalaba kangaka?
Nangona uluntu lwenzululwazi inkxaso ngenyaniso ukuba akukho ngozi kuMhlaba, eneneni umkhwa wahlukile. Ngamanye amazwi, inxalenye enkulu yoluntu ibandakanyekile ekugqibeni oko kuya kwenzeka kwisijikelezi-langa kungekudala. Noko ke, abaqondi kwaphela ukuba ziziganeko ezingaphaya kwamandla omntu.

Ukususela kwixesha elidlulileyo, ukuphela koMhlaba kube yinxalenye yengcamango yembali yoluntu. Uloyiko nokungaqiniseki okubangelwa kukungakwazi ukusabela kwintlekele kwenza isiseko sokubuza lo mbuzo: Siya kufika nini isiphelo?
Ngokusekelwe kuyo, Zonke iindidi zeethiyori zeyelenqe zenziwe ukuzityeshela ngokupheleleyo izigqibo okanye iingqikelelo zenzululwazi. Eyona idumileyo kuzo zonke yileyo yayibonisa ikhalenda yamaMaya ngo-2012.
Kulungile, ngokutsho kohlalutyo oluthile kunye nokungabikho kokuqina, babeka isiphelo soMhlaba ngoDisemba 21, 2012. Nangona kunjalo, njengoko kulindelwe kwaye, emva kwezilumkiso zesayensi ukuba akuyi kwenzeka, ngokwenene, akukho nto eyenzekayo.
Ngaphandle kwe-anecdote enjalo, Akuzange kubekho ithiyori yeyelenqe egquba ngolu hlobo phakathi koluntu ngokubanzi. Ukanti, kwakhona, inzululwazi yoyisa. Emva koko, ukususela ngoko, izazi ngeenkwenkwezi ziye zalawula ukuphikisa nayiphi na ingcamango yalo mba. Ke, ngokufutshane, i-End of Times ihlala ingaqinisekanga kwaye, ukuza kuthi ga ngoku, akunakwenzeka ukuba yenzeke.
Ke… yintoni enokubangela isiphelo soMhlaba ngokwesayensi?
Ngokucacileyo, iithiyori zeyelenqe azihambisani nezibakala ezixhasayo. Ngaphandle kwento yokuba zizithintelo ezilula ezingenantsingiselo, abantu banikezela kuloyiko kunye ne-echo yoluntu.
Ukutshintsha loo nyaniso, kubaluleke kakhulu zazi iingozi zokwenyani ezisongela umhlaba. Nangona isiphelo soMhlaba singenakwenzeka ngeli xesha langoku, oko akuthethi ukuba akukho mngcipheko ngokupheleleyo.
Khumbula ukuba i-cosmos ayinasiphelo, ngoko ilikhaya kuzo zonke iintlobo zezinto ezinokuba yingozi. Phakathi kwazo kukho iiasteroids ezintsonkothileyo nezibhadulayo, izidalwa ezidweliswa luluntu njengezidalwa ezixela kwangaphambili iintlekele.
Kodwa kwakhona, kukho izoyikiso ezibambekayo kumphezulu ngokwawo okanye umoya womhlaba. Yizo kanye ezi ziganeko zoyikiso ezibangela inkxalabo eyandayo phakathi kweengcali. Zisenokungafani nesiphelo soMhlaba, kodwa ukuba aziphathwa kakuhle, zinokuzisa amaxesha anzima kwixesha elizayo.
I-asteroid Apophis kunye nokuqikelelwa kwayo ngomhlaba
Ifunyaniswe ngoJuni ka-2004, iApophis yi asteroid entle ebeka isoyikiso kuMhlaba. Inamaphiko afikelela kuma-370 eemitha ububanzi, into eyoyikekayo.
Ngale ndlela, kwakungonyaka ka-2004. apho iApophis yabangela isiphithiphithi ngakumbi kuluntu lwezenzululwazi. Emva kokubonwa kwayo, i-asteroid, ngokwezibalo ezithile, yahlelwa njengesongelo sokwenyani nesinokuphela.
Esona sizathu sasikukuba i-Apophis yayiza kuwela kufutshane ngokwaneleyo eMhlabeni ukuze itsalwe kwindawo yayo yomxhuzulane. Nangona kunjalo, ixesha elithile kamva kwaye kude kube ngoku, intlanganiso elandelayo kunye ne-Apophis, ecwangciselwe i-2068, ayithethi nayiphi na ingozi.
I-colossus Bennu kunye nemilinganiselo yayo emangalisayo
Ukongeza kwi-Apophis, enye iasteroid esandula kufundwa nguBennu, into enkulu yasesibhakabhakeni eyabonwa ngo-1999 eSocorro, eMelika.Inobubanzi obungaphezulu kweemitha ezingama-480, lelinye lawona matye amakhulu asemajukujukwini kufutshane ne-orbit yomhlaba.
Enyanisweni, iimpawu zayo ezithile ziye zayenza ukuba ibe yinto yokufunda indawo ye NASA. Phakathi kwazo, i-OSIRIS probe yendawo iceba ukuqokelela imathiriyeli enamatye kangangoko kunokwenzeka ukuhlalutya i-asteroid. Ngeziphumo ezifunyenweyo, iimfihlelo ezininzi malunga nabo kunye nokuziphatha kwabo ziya kutyhilwa.
nangona kwixesha elizayo ayibeki isoyikiso ngqo kuMhlaba, UBennu uya kuhlala efundisiswa. Njengoko iyi-asteroid entsonkothileyo kwaye engaqondakaliyo, akwaziwa ngokuthe ngqo ukuba kuya kwenzeka ntoni kumashumi ambalwa eminyaka.
Ukufudumala kwehlabathi kuyinyaniso
Uluntu lonke lwezenzululwazi, ngaphaya kwe-astronomy, lugxininise ingozi ebangelwa kukukhutshwa okugqithisileyo kwe-CO₂. Ngokuqokelela le gesi kunye nezinye, kunye nemiphumo eyingozi, iplanethi iqala ukutshintsha kakhulu.
Ngaloo ndlela, ukufudumala kwehlabathi iye yalushiya uphawu okokugqibela. Ukutshintsha kwemozulu, kunye nokunyibilika komkhenkce, zezinye zeempawu zolu rhwebo luxhalabisayo. Mhlawumbi isiphelo soMhlaba asikho emajukujukwini, kodwa kumhlaba wawo ukuba kukho into engenziwanga ngawo.
Siya kuba yintoni isiphelo somhlaba ngokwenene? Ngaba ngokwenene uyafuna ukwazi?

Ngokusa okutsha kunye nenkqubela phambili yetekhnoloji, ukufumanisa ukuba siya kuba yintoni isiphelo soMhlaba yinto enzima. Ukongeza kwimiba enokwenzeka esele iphakanyisiwe, kukho ezinye ezimbalwa ezinokungena kolo luhlu.
kunjalo, uluntu lwezenzululwazi lucacisa ukuba akukho meko imbi kuMhlaba kumashumi eminyaka ezayo. Kakade ke, impembelelo yomntu kwimekobume imele ilawulwe ukuze kuthotyelwe loo mbono.
Ngaphandle koko, impendulo kuphela enengqiqo kwinto eya kuba yisiphelo soMhlaba, igxininise ngakumbi kwinyani yokuphela kwelanga. Kunjalo, umama inkwenkwezi ayingomntu ongenasiphelo, ngoko ke ukuguga kwayo kwixesha elizayo yeyona meko ichaseneyo.
