Ukuhlola isimiso sethu sonozungezilanga kuye kwaveza okunye okutholwe okumangalisa kakhulu kwesayensi yamaplanethi. Esinye sezambulo ezithakazelisa kakhulu kube ukutholakala kwemihlaba enolwandle olungaphansi komhlaba okukholakala ukuthi ifihla ukuphila.
Le mihlaba ayitholakali kuphela ezindaweni ezingaphandle zesimiso sethu sonozungezilanga, kodwa futhi phakathi kwamasathelayithi aneqhwa amaplanethi amakhulu njenge-Europa, Titan, kanye ne-Enceladus. Ngisho nePluto, iplanethi ekude, kukholakala ukuthi inolwandle olufihlwe ngaphansi komhlaba.
Ngosizo lobuchwepheshe obuthuthukisiwe kanye nelukuluku elingapheli labacwaningi, sikwazile ukujula ngezimfihlakalo zale mihlaba.
I-Southwest Research Institute usosayensi weplanethi u-S. Alan Stern ubhala embikweni owethulwe eNgqungqutheleni yaminyaka yonke yama-52 yeLunar and Planetary Science (LPSC 52) ngoMashi 2021 ukuthi ukusabalala komhlaba wamanzi olwandle lwangaphakathi (IWOWs) ohlelweni lwethu sonozungezilanga kuphakamisa ukuthi kungenzeka kuvame kwezinye izinkanyezi. nezinhlelo, ezandisa kakhulu izimo zokuhlala kweplanethi nokuphila kwebhayoloji ngokuhamba kwesikhathi.
Sekuyiminyaka eminingi ososayensi bazi ukuthi imihlaba enolwandle endaweni yayo, njengoMhlaba, kufanele ihlale ebangeni elithile ukusuka ezinkanyezini ukuze igcine amazinga okushisa agcina lezo zilwandle ziphila. Ama-IWOW, ngakolunye uhlangothi, angabonwa ebangeni elikhulu kakhulu ukusuka ezinkanyezini zawo. Lokhu kwandisa ngokuphawulekayo inani lemihlaba okuhlalwa kuyo okungenzeka ibe khona kuwo wonke umthala.
Imihlaba efana nomhlaba enolwandle nayo isengcupheni yezingozi ezihlukahlukene zokuphila, kusukela emkhathini wesibhakabhaka kanye nenkanyezi enomsila kuya ekukhanyeni kwezinkanyezi eziyingozi, ukuqhuma kwe-supernova engumakhelwane, nokuningi. Ngokusho kwe-athikili ye-Stern, ama-IWOW awavikelekile ezinsongweni ezinjalo ngenxa yokuthi ulwandle luvikelwe yiqhwa nedwala elingamakhilomitha amaningana kuya kwamashumi amaningi amakhilomitha futhi limboze izilwandle zawo.
“Imihlaba yasolwandle emanzini ikufanelekela kangcono ukunikeza izinhlobo eziningi zokuzinza kwemvelo, futhi mancane amathuba okuba ibhekane nezinsongo zokuphila ezivela emkhathini wazo, inkanyezi yawo, isimiso sonozungezilanga, kanye nomthala, kunemihlaba efana noMhlaba, izilwandle ngaphandle,” kusho uStern.
Uphinde aveze ukuthi ukumbozwa okufanayo kwamatshe neqhwa okuvikela ulwandle kuma-IWOWs nakho kuvikela impilo ekubonweni cishe ngazo zonke izindlela zezinkanyezi.
Uma imihlaba enjalo iyindawo yokuqala yokuphila emthaleni nempilo ekhaliphile ikhula kuwo - "uma," amanothi amakhulu - ama-IWOW angasiza ukuxazulula inkinga. I-Fermi Paradox.
I-Fermi Paradox yisihloko esabekwa ekuqaleni kwawo-1960 ngu-Enrico Fermi, kamuva owawina uMklomelo KaNobel kuPhysics. Ibuza ukuthi kungani bungekho ubufakazi obucacile bokuphila uma bugcwele indawo yonke. "Ungqimba olufanayo oluvikelayo lweqhwa nedwala oludala izindawo ezizinzile zokuphila luphinde luthathe leyo mpilo ekutholakaleni kalula," kusho uStern.
Sengiphetha, ukutholakala kwemihlaba enezilwandle ezingaphansi komhlaba kuye kwashintsha umkhakha wesayensi yeplanethi kule minyaka engu-25 edlule. Njengoba ukuba khona kwemihlaba enjalo kuvame esimisweni sethu sonozungezilanga, lokhu kusho ukuthi maningi amathuba okuba sithole ukuphila ngale koMhlaba kunalokho obekucatshangwa ngaphambili.
Amasathelayithi aneqhwa amaplanethi amakhulu afana ne-Europa, i-Titan, ne-Enceladus, namaplanethi akude afana ne-Pluto, manje asengamakhandidethi aphambili okuhlola nokutadisha okwengeziwe, njengoba engase abe nokhiye wokuvula izimfihlakalo zokuphila endaweni yonke.
Amathuba awapheli ngempela, futhi okutholwe yile mihlaba ngokungangabazeki kuzoqhubeka nokuthatha imicabango yethu iminyaka eminingi ezayo.
Ukwaziswa okwengeziwe: "Eminye Imithelela Kokubili Ukuphila Nempucuko Mayelana Nemihlaba Yangaphakathi Yasolwandle Yamanzi".
