Stiven Hoking: Earth ayaa u beddesho karaan meeraha koriyo isla sida Venus

Earth wuxuu beddeli karaa meeraha Venus lagu koriyo oo kale, iyada oo badaha, roobka acid karkaraya, ma haddii dadka loo xakameeyo kara isbedelka cimilada karin. Tani waxaa lagu sheegay in waraysi uu dhawaan siiyay jirka Stiven Hoking. "Waxaan ku dhow inay dhibic tankeeda halkaas oo kululaaneysa ee caalamka uu noqon doonaa mid laga bogsoon yihiin. tallaabo Trump ee riixdo laga yaabaa in Earth galay buur, iyo waxa la mid ah sida Venus, halkaas oo heerkulka celcelis ahaan waa 250 degrees Celsius iyo Samada halkii roob lagu dhibciyo sulfuric acid "waxay noqon doontaa, - ayaa sheegay in Stiven Hoking, tixraaca samaynta go'aanka Donald Trump on bixitaanka Mareykanka heshiiska Paris cimilada.

falcelinta erayada Hawking

Si kastaba ha ahaatee, inta badan saynisyahano ayaa sheegay in dhacdadaas oo kale waa buunbuunin yaabo iyo riwaayado. Marka la barbar dhigo Venus, Earth waa meel aad u fog ka Sun ah, iyo sababta oo ah Halabuurka kiimikada ay, Yaanay noqon doona jawi isku cufan ka kooban carbon dioxide, sidaas darteed in heerkulka on Earth inuusan weligiisna gaari doonin 250 degrees Celsius. Laakiin halka khubarada isku raacsan yihiin in dhibaatada arrimuhu guud ee isbedelka cimilada musiibo waa ma noqon karaan kuwo ka badan oo degdeg ah. "Xaaladdan oo kale, Hawking ayaa cod karsanaa," - yiri Maykl Mann, climatologist Maraykanka ee Pennsylvania State University. - Earth ka fog yahay ka Sun ee ka badan Venus, sidaa daraadeed waxa aan awood u yeelan doonaan in ay la kulmaan saameyn la mid ah lagu koriyo on baaxadda isla, kaas oo la kulma ay Venus, waxa duniduna ma ay kari doonaan badaha ee dareenka suugaan. Si kastaba ha ahaatee, dhibaato guud oo ah in ay saameeyeen Hawking, taas oo ah in dhulkeenna laga yaabaa inay noqdaan noolaan karin u ah nolosha aadanaha, haddii Dadka ma aha in isbedel khatar ah cimilada waa deg deg ah.

meeraha hothouse

Venus - Tani waa meeraha labaad ka Sun ah, waana meeraha ugu ifka badan ee Nidaamka Solar. Inkasta oo ay la magacaabay ka dib markii ilaahadda Roman jacaylka iyo damaca, uma baahnid inaad si ay u qorsheeyaan safar jaceyl la lamaanahaaga meerahaas mustaqbalka dhow. In kasta oo xaqiiqda ah in size ee Venus dhow yahay size la mid ah sida dhulka, oo halkaas wuxuu dhacaa cuf la mid ah, haddii kale waa mid aad u kala duwan oo ka soo Dhulka oo biyo ah. Venus - sidoo kale waa meeraha ugu kulul ee nidaamka qoraxda, iyo heerkulka waxaa ay gaari karaan 466 degrees Celsius. Sababta heerkulka sida uu yahay jawiga cufan iyo qarada waaweyn oo carbon dioxide, kaas oo waxaa la helay iyagoo daruur ah ee sulfuric acid oo dhan. Iyadoo la raacayo, jawiga nuuga kulaylka ka sii badan intii dhulka jawi. Intaa waxaa dheer, Venus waa badan u dhaw in ay qorraxda, maxaa yeelay, taas oo nuuga shucaaca ka badan Dhulka. marno firfircoon fara badan yihiin oo kaliya dheeraadka kale ee fasalka wadada Ada, taas oo uu leeyahay Venus. Fikradda asaasiga ah ee sababta Venus Maarraynta muuqashadii Jahannamo been in xaqiiqda ah in meeraha ahaa ee aan dhammaadka lahayn wareegga wax loop. Planet nuuga shucaac badan radiated, ay sabab u tahay taas oo uumiga biyaha iyo aad u badan iyo cunfiga shaabadeeyey in jawiga, taas oo iyana keentay in nuugista of tiro ka sii weyn kulaylka iyo kululaaneysa joogto ah, oo loo yaqaan saamayn lagu koriyo ah. "Si fudud u gelin, Venus helay a" stroke kulaylka ": meeraha waa si joogto ah kulul, laakiin ma qabow waayeen", - ayaa sheegay in Tyler Robinson, astrobiologist at the University of Washington.

seenyo An yaabo dhulka

Inkastoo dadka badankoodu iska falno joogtada ah ee dhulka cimilada, meeraha maray isbedel badan oo cajiib ah in ay taariikhda, oo dhererkiisu yahay 4.5 bilyan oo sano jir. Inta lagu guda jiro Oxygen sare, kaas oo ka dhacay oo ku saabsan 2.5 billion sano ka hor, cyanobacteria photosynthetic xanaajiyeen kordhay cajiib ah qadarka oksijiin ee jawiga. Ilaa 650 milyan oo sano ka hor caalamka si buuxda u dhegtay, noqdo mid baraf weyn. Oo wakhtiga dinosaurs on heerkulka Earth ahaa celcelis ahaan 10 degrees Celsius ka badan hadda, sababtoo ah jawiga ayaa weli ahayd hodan ku carbon dioxide. A kaarboonka weyn ayaa sababay noolaha badan ee la soo dhaafay, tusaale ahaan, eynu ku dhammaadka xilligii Permian, ku saabsan 252 milyan oo sano ka hor, marka badda nolosha ku saabsan boqolkiiba 95 ku dhintay sabab u qayilo ee badaha.

Earth uma oggolaan doono in qaddar ee Venus

Sidaas awgeed waa in aan macquul ahayn si ay u eegaan seenyo musiibo weyn cimilada. Si kastaba ha ahaatee, khubarada badankooda weli aaminsan yihiin in dhacdadaas oo kale waa heer sare lagama yaabo. In aragtida, geeddi-socodka la mid ah, kaas oo la bilaabay on Venus, dhici kartaa in dunida, laakiin waxaa xusid mudan in habkan qaadan doonaa boqolaal malaayiin sano. Sidaas daraaddeed sida ay khubaro badan. Sidoo kale, suurtagalnimada in badaha dhulka kari doono si la mid ah sida badaha ku Venus waa mid aad u yar.

Ilaaliya dhulka?

Xaqiiqada ah in Earth la ilaaliyo shucaaca qoraxda waa jawi in uu yahay mid ka duwan jawiga of Venus. "Jawiga ee Venus waa qiyaastii boqol jeer ka sii dhumuc weyn iyo denser badan dhulka jawiga, oo sidaas waa ka kooban yahay ku dhowaad oo gebi of carbon dioxide," - yiri Robinson. Wixii la barbardhigo jawiga Dhulka, wuxuu ka kooban yahay inta badan ee nitrogen kelli iyo oksijiin, iyo boqolkiiba 0.04 tiriyaa carbon dioxide.

Land hore u soo maray ugu xumaa

Haddii aan jawiga cufan oo ah carbon dioxide iyo qiyaas dheeraad ah ee shucaaca qoraxda suurtagalnimada in dhici doona seenyo la mid ah dunida, iyo in Venus waa mid aad u yar. Ma jiro eegaayo qumman ee gaasas lagu koriyo oo kale ka mid ah xaqiiqooyinka ay waxaa lagu yaqaan in dadka maanta. Intaa waxaa dheer, ee la soo dhaafay on Earth ahaayeen xaaladaha cimilada diiran, tusaale ahaan, inta lagu guda jiro Epoch Eocene (inta u dhaxaysa 56 iyo 34 milyan oo sano ka hor). Waqtigaas, content carbon dioxide ee jawiga uu ahaa saddex jeer ka badan this. Xitaa haddii aad qiyaasi mustaqbalka ka mid ah baabuurta, diyaaradaha iyo qaboojiyaha oo dhan, ma Saadaasha cimilada ma awoodi doonaan in ay muujiyaan heer la mid ah ee carbon dioxide in jawiga.

hanad shar of script

maanta saamayn aqalka dhirta lagu koriyo la xakamaynin ma matali karto khatar dhab ah in meeraha. Laakiin, dabcan, waxaa had iyo jeer waa khatar ku waxyeeleynayo ula kac ah. Dr. Xun been abuuran karo xal injineernimada, la mid ah kuwa la soo jeediyey ee intaa dheer in terraform Mars, laakiin baaxadda ficilkan oo kale waa in ay noqdaan weyn. Waxaad u baahan doontaa fluorocarbons, sidaas Dr. Xun yeelan doonaan inay oogaan Diinta dunida ah, ka go'an in ay isticmaalka Reebay hairspray iyo shiir. Laakiin halkan yimaado dhibaatada: ee la soo dhaafay in qaar ka mid ah waxyaabaha la buufiyo macaamiisha loo isticmaalo fluorocarbons, si kastaba ha ahaatee, qayb waxaa lagu mamnuucay in loo isticmaalo ee todobaatanaadkii daahay.

masiibo cimilada waa suurto gal

Si kastaba ha ahaatee, dunida uma baahna in ay noqoto labaad Venus ah, sidaa darteed waxa uu noqonayaa mid laga nacay nolosha aadanaha. Heshiiska Paris sheeganayso in ay qaban kulaalaya in ka yar laba darajo Celsius kor ku heerkulka pre-warshadaha. Laakiin xitaa heerka this hayo muddo dheer waxay keeni kartaa isbedel karin in mar hore bilaabay. Kuwani isbedel cimilada keeni karaa dhaawac musiibo in la lafaguro jidhadhka dhulka, iyo sidoo kale beeraha.
