Panspermia - waa fikrad ah oo ku saabsan muuqaalka kore ee nolosha on Earth. caddayn panspermia

Ka mid ah aragtiyaha ku saabsan asalka ah ee nolosha on Earth la xiqiijiyay in panspermia haya meel gaar ah. Ra'yiga Tani waa arrin qalaad. Wuxuu sidoo kale dhigayaa in nolosha on dhulkeenna ayaa dabiiciga ah runtan. uurjiifka Its la keenay dhulka la jirka kale samadu (tus dhagax xiddig) ama markab shisheeye. Panspermia - in fikrad ah, muuqaalka kore ee kaas oo la xidhiidha magaca Faylasuuf qadiimiga Aristotle. Taageerayaasha of aragtida ah ayaa ku noolaa qarniyo XVII-XVIII. Gotfrid Leybnits. Si kastaba ha ahaatee, kaliya ee bilowga ah ee panspermia qarnigii XX waxaa iska daayeen inay noqon sababaynta falsafada iyo helay Fikirka ka duwan oo lagu daydo.

panspermia shucaaca

In 1908, saynisyahan Swedish Svante Arrhenius horey fikradda, loo yaqaan aragtida panspermia shucaac. jirka ayaa soo jeediyay in kudka bakteeriyada ahaayeen ugu horeysay ee adduunka ka dib markii uu socdaalka ka rukummada fog ee caalamka. Sababta tani "socdaalka" Arrhenius dareemay cadaadiska qoraxda (light ama xiddiga kale ee weyn).

xiqiijiyay in panspermia waxa uu leeyahay taageerayaal badan. The nolosha ay isirka u badan tahay, saynisyahano, kuwaas oo wac Venus, halkaas oo bakteeriyada kulaylka u adkaysta ka heli kartaa on Earth mar marka labada meerayaasha ahaayeen meel fog ka ugu gaaban midba midka kale ka.

cadaadiska Factor light

Jiritaanka cadaadis iftiin Arrhenius hor cadeeyay jirka experimentally Ruush Pyotr Lebedev. Waxaa intaa dheer, waxa uu falanqeeyay saamaynta this ifafaale on the kudka Lycopodium (Lycopodium). Marka tan la eego, in qarnigii XIX ah, aragtida ah ee panspermia taageeray Ferdinand Cohn, Justus von Liebig, Germanom Gelmgoltsem, iyo aqoonyahanno kale oo qudbad uu waqti.

Si kastaba ha ahaatee, qarnigii XX ah, fikrad this ayaa haatan lagu eedeynayaa cilmi badan oo kala duwan. iyaga dhex yiil, doisprezece Shklovsky, Carl Sagan iyo kuwa kale. Dadka ka soo horjeeda diidi xujada panspermia, sabab ah in socdaalka meesha bannaan ee muddada dheer ma aan samayn karo aan dose shucaaca khilaafka burbur.

meel visitors

In guud foomka of aragti panspermia u akhriya in vacuum ah, taas oo u safri karaan bakteeriyada iska dhex degtaan dheer, waa in aanay carqalad la noloshooda, tan iyo heerkulka at aad u hooseeya, unugyada waa la xayiray (animation ganaax). Fikrad ahaan guests caynkan oo kale ah "toos" isla markiiba ka dib markii uu yimid in Earth, halkaas oo la horumariyo a mahad cimilada raaxo leh si kadis ah duruufaha badan.

Fikradaha kor ku xusan ayaa lagu beeniyay by culimada casriga ah. Studies ee shaybaarka waxay muujiyeen in in vacuum ee cell meel si fudud u qaraxdo sabab u uumi biyo superfast u gaar ah. Wacan tahay habkan sheyga waxaa lagu halligay cadaadiska gudaha xad-dhaaf ah. Tani waa dood ugu muhiimsan ee khubaro kuwaas oo aaminsan in panspermia shucaaca - quraafaad ah.

Litopanspermiya

nooc kale oo panspermia - litopanspermiya. Aasaasihii of aragtida ah ee Melvin Calvin rumeysan yahay in bilowga nolosha ka heli kartaa caalamka, oo ay weheliyaan meteorite ah. Ilaa iyo hadda, fikradda guud ee panspermia aan la xoojiyaa oo ay biilka u dhigma.

On Earth runtii aad u hesho hadhaaga yar ee meteorites gubo in jawiga. qalab noocan oo kale ah bartay noocyo kala duwan oo saynisyahano, laakiin ma jirto cid weli awoodin in ay iyaga ka heli ama iyaga oo ku raad nolosha. Qubarada oo kaliya qaar ka mid ah walxaha noolaha go'an (tus dufanka leh acids iyo acids amino).

Ra'yiga dhagax xiddig

xiqiijiyay in kale oo ku saabsan muuqaalka kore ee nolosha on Earth, ee la xidhiidha panspermia, ee loo yaqaan aragtida ah dhagax xiddig lagu soo bandhigay kitaabka Freda Hoyla "nool daruur". In qoraalkaan, qoraaga ayaa isku dayay in uu cadeeyo meelmar ah ee ay fikirka ku saabsan tusaale ahaan ka mid ah cudurrada dillaaca virus caalamiga ah (oo ay ku jiraan tusaale ahaan ka mid ah hargabka Spanish qarnigii hore XX). Hoyle soo jeediyay in cudurka mass sida (faafa) waxaa lagu sharaxi karaa iyaga oo asal ahaan cometary. In si la mid ah sida fayraska, Earth nolosha ka heli karto, qoraaga ayaa sheegay.

Leeyihiin doodaha iyo soo horjeeda ee aragtida ah ee asal ahaan cometary bakteeriyada. virologists intooda badan isku raaceen in, tusaale ahaan, faafa hargabka ee Hong Kong inta lagu jiro 1968-1969. ka badan ayaa macquul ah sharxayaa gudbinta cudurka qof ilaa ka qof iyo horumar in dagaalka ka dhanka ah habka difaaca jirka, ka badan fikirka ah iyada oo xididdada runtan. Intaa waxaa dheer, litopansermiya - xiqiijiyay in aan la macnayn karaa sida naasohoodu leh bakteeriyada galay nidaamka qoraxda nidaamka xiddigta kale, halkaas oo, laga yaabee, waxaa jira calaamadaha nolosha.

panspermia faray

In 1970-mada. in bulshada sayniska waxaa jira aragti kale oo geesi ah oo asal ahaan nolosha on Earth - panspermia faray. fikrad Tani aan la haddii aadan ee mawduuca ka dibna-caanka ah ee sirdoonka leeska celin. Haddii aad aaminsan tahay panspermia ku faray, miraha ugu horreeya ee nolosha u muuqday on Earth Emaraadka ilbaxnimada gaar ah, ee hadda jira meel guntiisa meel. Waxaa laga yaabaa in kudka iyo bakteeriyada soo diray on mashiinka khaas ah, oo waxay ku wada sameeya la abuuro of gumeysi ama tijaabo cilmi ah.

Taageerayaasha fikradda ah panspermia faray sida ay cadeyn waxaa la xusuusiyey in dhammaan noolaha jidhadhka leeyihiin in ay qaab-dhismeedka waa dhif on biraha dhulkeenna, oo ay ku jiraan molybdenum. Sabab kale oo been dabiiciga ah ee code hidaha. The asal ahaan of this ifafaale ayaa weli si buuxda u fahamsan yahay. Sababtoo ah oo ka mid ah dhibco badan cad u muuqdaan fikradaha ugu aan awoodi karo, gaar ahaan la xiqiijiyay of panspermia faray. apologists Its qabaa in dhamaan noolaha jidhadhka dhulka ka awoowe caadi ah (noole) soo degay, halkan muuqday mahad ilbaxnimada ah leeska celin. Dhanka kale, waxaa weli ma jirto wax caddayn ah oo nadiif ah jiritaanka shisheeyaha iyo booqashooyin ay u Earth.

Carro runtan

panspermicheskaya kale oo la xiqiijiyay in booguhu waxay ku dhaadhacay male ah in uu dhulka la uumay ciidda runtan, kaas oo ku jiray jeermiska nolosha. Xaaladdan oo kale, bakteeriyada ku noolaan karaa oo keliya marka la haynta heerkulka ah oo deggan on meeraha cusub. Si kastaba ha ahaatee, saynisyahano cilmi waxay muujiyeen in in marxaladaha hore ee jiritaankeeda, Earth ahaa kubad cas-kulul, taas oo uu sii waday si uu ku qaboojiyo in ka badan malaayiin badan oo sano.

Si kastaba ha ahaatee ciidda runtan sida side nolosha ka heli karto on dhulkeenna badan ka dib. Tani waa fikrad kale, kuwaas oo soo jeedisay panspermia. Si kooban, fikrado kuwanu waa suuragal ahayn in 1970. Waxa uu cadeeyay oo ay ku jirto cilmiga Soofiyeeti Lev Mukhin. Kasta oo xeryahooda organic adag hortiisa ka muuqan doonaa dunida oo dhan, waa in ay ka gudbaan jawi dhulka, halkaas oo ay ku soo wada combusted la meteorites iyo waxyaabaha kale ee bannaan.

roobab "Live"

Doodaha ugu danbeeyay ee ku saabsan nooca nolosha dhulka bilaabay meel sannadkii 2001, markii dawladda Indian of Kerala Roobka gaar ah oo cas. gaar ee ifafaale this dabiiciga ah ma ahaa la filayn oo keliya adag. Goob sheegay roob roobabka ka hor inta aysan goob joog duufaan aan caadi ahayn oo sii daysa iftiinka awood badan.

The ifafaale roob cas ayaa soo jiitay ee saynisyahano iyo amateurs ka adduunka oo dhan. waxbarashada dheeraad ah ayaa muujiyay in sababta dhabta ah ee qayb ka steel midabka adaanaha joogay oo biyaha qaab slurry a. dareenka maleegay ahaayeen khilaafaadka. Waayo, taageerayaasha panspermia xaqiiqda weli muran kale oo ay guushu ku fikirka ah ee asal ahaan runtan nolosha dhulka.

Roobka ugu horreeya sida ka kudka, taas oo ka hor on meeraha weligii inuu halkaas tago ka badan balaayiin Earth sano ka hor karin? khubarada badankooda fasiray dhacdooyinka ee Hindiya kastaba. Seynisyahanno ku ogaaday in kudka in wada dhaceen roobka cas, waxaa iska lahaa epiphytes ah - dhirta maanka ku caan sii kordhaya meel kasta oo qayb ka this ee dunida. Sayidka, roobabka waxay ahaayeen wareegga dhacdo kaliya ee walxaha organic ee dabiiciga ah. Si kastaba ha ahaatee, qaybtii ugu roobka cas ee Kerala muujiyeen sida dhici dhici kara gumaysigii nolosha dhulka.

Search The sii

Si aad u taariikhda, ma mid oo ay heli waayeen caddaymo nolosha ka baxsan Dhulka (oo ay ku jiraan in arrinta meteoritic lifaaqan meeraha saddexaad ee nidaamka qoraxda ka meel dibadda ah). Marmar, warbaahinta muuqan warbixin cajiib ah oo ku saabsan natiijooyinka sida, laakiin dhab ahaantii dhabta ah waa fasiraadda khalad ah xaqiiqooyinka ama been ula kac ah. Inta badan, waayo jirkaaga ah in la qaato xeryahooda ka imanba sida bakteeriyada. Intaa waxaa dheer, ku dhacaan dhulka ku, arrinta runtan "wasakh ah" nolosha dunida, taas oo sii jahawareerinaya observer ah.

dood intaas oo dhammu waxay muujiyaan panspermia in - mala-shaki, kaasi oo aan lahayn saldhig cadaymaha. Si kastaba ha ahaatee, shaki sayniska ma hortago dhowr ah oo muhiim ah oo dunida ka wadaan baadi doodo si ay u taageeraan aragtiyaha sida.
