Nemuseli narazi\u0165 do plan\u00e9ty, no na spustenie vymierania sta\u010dila ich gravit\u00e1cia, informuje Universe Today.<\/a><\/p>\n

Fargion predstavil svoju hypot\u00e9zu na vedeckej konferencii venovanej vysokoenergetick\u00fdm kozmick\u00fdm zdrojom. Tvrd\u00ed, \u017ee v d\u00e1vnej minulosti mohli vn\u00fatornou \u010das\u0165ou Slne\u010dnej s\u00fastavy prech\u00e1dza\u0165 trpasli\u010die plan\u00e9ty<\/a> alebo in\u00e9 ve\u013ek\u00e9 objekty s hmotnos\u0165ou porovnate\u013enou s Mesiacom \u010di dokonca s plan\u00e9tami.<\/p>\n

Tak\u00e9to teles\u00e1 by pod\u013ea neho vytvorili extr\u00e9mne slapov\u00e9 sily podobn\u00e9 t\u00fdm, ktor\u00e9 dnes sp\u00f4sobuje Mesiac. Rozdiel by v\u0161ak bol obrovsk\u00fd. Namiesto be\u017en\u00e9ho pr\u00edlivu a odlivu by Zem zasiahli gigantick\u00e9 vlny, rozsiahla vulkanick\u00e1 aktivita a prudk\u00e9 klimatick\u00e9 zmeny.<\/p>\n

Priamy n\u00e1raz tak\u00e9hoto telesa do Zeme by predstavoval extr\u00e9mne vz\u00e1cnu udalos\u0165. Ove\u013ea pravdepodobnej\u0161\u00ed scen\u00e1r pod\u013ea autora zah\u0155\u0148a bl\u00edzky prelet. Pr\u00e1ve ten mohol pod\u013ea jeho v\u00fdpo\u010dtov vyvola\u0165 katastrofy<\/a> schopn\u00e9 zmeni\u0165 v\u00fdvoj \u017eivota na celej plan\u00e9te. Vedci u\u017e desa\u0165ro\u010dia sk\u00famaj\u00fa pr\u00ed\u010diny ve\u013ek\u00fdch vymieran\u00ed. Niektor\u00e9 pr\u00edpady maj\u00fa pomerne jasn\u00e9 vysvetlenie. Pri vyhynut\u00ed dinosaurov existuj\u00fa presved\u010div\u00e9 d\u00f4kazy o dopade ve\u013ek\u00e9ho asteroidu vr\u00e1tane sl\u00e1vnej ir\u00eddiovej vrstvy rozpt\u00fdlenej po celej plan\u00e9te. Pri in\u00fdch udalostiach v\u0161ak situ\u00e1cia nie je tak\u00e1 jednozna\u010dn\u00e1.<\/p>\n

M\u00f4\u017ee za masov\u00e9 vymierania na Zemi gravit\u00e1cia?<\/p>\n

Najv\u00e4\u010d\u0161ie vymieranie v hist\u00f3rii Zeme nastalo pred pribli\u017ene 251 mili\u00f3nmi rokov na hranici permu a triasu. O \u017eivot vtedy pri\u0161lo 80 a\u017e 95 percent v\u0161etk\u00fdch druhov. Vedci dodnes diskutuj\u00fa o tom, \u010do presne katastrofu sp\u00f4sobilo.<\/p>\n

\u201ePri permsko-triasovom vymieran\u00ed neexistuje ani ir\u00eddiov\u00e1 anom\u00e1lia, ani ve\u013ek\u00fd impaktn\u00fd kr\u00e1ter, ktor\u00fd by sa dal jednozna\u010dne spoji\u0165 s touto udalos\u0165ou,\u201c upozor\u0148uje Fargion.<\/p>\n

Pr\u00e1ve preto navrhuje alternat\u00edvne vysvetlenie. Pod\u013ea jeho predstavy mohol okolo Zeme preletie\u0165 objekt s hmotnos\u0165ou trpasli\u010dej plan\u00e9ty. Gravita\u010dn\u00e9 p\u00f4sobenie n\u00e1sledne rozkol\u00edsalo oce\u00e1ny, deformovalo zemsk\u00fa k\u00f4ru a zv\u00fd\u0161ilo aktivitu magmy hlboko pod povrchom. V\u00fdsledkom mohli by\u0165 obrovsk\u00e9 cunami, mas\u00edvne sope\u010dn\u00e9 erupcie a klimatick\u00e9 zmeny trvaj\u00face cel\u00e9 roky.<\/p>\n

Zauj\u00edmavou \u010das\u0165ou hypot\u00e9zy je aj poh\u013ead na syst\u00e9m Zem-Mesiac. Autor upozornil na \u00fadaje z\u00edskan\u00e9 zo skamenen\u00fdch koralov. Tie nazna\u010dili, \u017ee pribli\u017ene na konci dev\u00f3nu sa tempo vz\u010fa\u013eovania Mesiaca od Zeme n\u00e1hle zmenilo. Pod\u013ea Fargiona by tak\u00fato zmenu mohol vysvetli\u0165 pr\u00e1ve gravita\u010dn\u00fd vplyv ve\u013ek\u00e9ho telesa po\u010das bl\u00edzkeho preletu.<\/p>\n

Nejde v\u0161ak o v\u0161eobecne prijat\u00fa te\u00f3riu. Samotn\u00fd autor prizn\u00e1va, \u017ee presn\u00fd po\u010det podobn\u00fdch objektov ani ich hmotnos\u0165 zatia\u013e nikto nepozn\u00e1. Ch\u00fdbaj\u00fa tie\u017e priame d\u00f4kazy, ktor\u00e9 by jednozna\u010dne potvrdili konkr\u00e9tny prelet v \u010dase jednotliv\u00fdch vymieran\u00ed. To znamen\u00e1, \u017ee hypot\u00e9za zatia\u013e patr\u00ed medzi odv\u00e1\u017enej\u0161ie vedeck\u00e9 n\u00e1vrhy a bude potrebova\u0165 \u010fal\u0161ie overenie.<\/p>\n

Fargion sa napriek tomu zam\u00fd\u0161\u013ea aj nad bud\u00facnos\u0165ou. Ak podobn\u00e9 objekty v minulosti skuto\u010dne nav\u0161t\u00edvili vn\u00fatorn\u00fa \u010das\u0165 Slne\u010dnej s\u00fastavy, teoreticky by sa podobn\u00e1 udalos\u0165 mohla zopakova\u0165 aj v bud\u00facnosti.<\/p>\n

\u201eAk objav\u00edme prich\u00e1dzaj\u00face teleso dostato\u010dne skoro, m\u00f4\u017eeme sa pripravi\u0165 alebo sa pok\u00fasi\u0165 odkloni\u0165 men\u0161ie objekty,\u201c uv\u00e1dza vedec.<\/p>\n

Pri ve\u013ek\u00fdch teles\u00e1ch by v\u0161ak \u013eudstvo ve\u013ea mo\u017enost\u00ed nemalo. Najv\u00e4\u010d\u0161ie nebezpe\u010denstvo by pod\u013ea jeho v\u00fdpo\u010dtov nepredstavoval samotn\u00fd objekt, ale obrovsk\u00e9 slapov\u00e9 vlny, ktor\u00e9 by mohli obieha\u0165 plan\u00e9tu cel\u00e9 roky. Autor dokonca navrhol budovanie bezpe\u010dn\u00fdch \u00fato\u010d\u00edsk vo vysok\u00fdch horsk\u00fdch oblastiach.<\/p>\n

\u0160t\u00fadia priniesla e\u0161te jednu zauj\u00edmav\u00fa my\u0161lienku. Fargion nazna\u010dil, \u017ee podobn\u00e9 katastrofy by mohli \u010diasto\u010dne vysvetli\u0165 aj sl\u00e1vny Fermiho paradox<\/a>. Ten sa p\u00fdta, pre\u010do napriek obrovsk\u00e9mu mno\u017estvu hviezd a plan\u00e9t nevid\u00edme zn\u00e1mky mimozemsk\u00fdch civiliz\u00e1ci\u00ed.<\/p>\n

\u201eAstrofyzik\u00e1lne slapov\u00e9 katastrofy m\u00f4\u017eu z \u010dasu na \u010das vymaza\u0165 aj technologicky vyspel\u00e9 civiliz\u00e1cie a vr\u00e1ti\u0165 \u017eivot na primit\u00edvnej\u0161iu \u00farove\u0148,\u201c domnieva sa vedec.<\/p>\n

\u010ci sa t\u00e1to hypot\u00e9za uk\u00e1\u017ee ako spr\u00e1vna, zatia\u013e nikto nevie. Pripom\u00edna v\u0161ak, \u017ee hist\u00f3ria Zeme aj celej Slne\u010dnej s\u00fastavy st\u00e1le ukr\u00fdva mno\u017estvo nezodpovedan\u00fdch ot\u00e1zok. A niektor\u00e9 z nich mo\u017eno nes\u00favisia iba s asteroidmi, ale aj s obrovsk\u00fdmi telesami, ktor\u00e9 na\u0161u plan\u00e9tu v d\u00e1vnej minulosti mo\u017eno iba tesne minuli.<\/p>\n
