V\u011bdci zjistili, kde se vzalo tolik vody pro d\u00e1vnou katastrofu<\/strong><\/p>\n

Pod povrchem na\u0161\u00ed planety, v hloubce n\u011bkolika stovek kilometr\u016f jsou obrovsk\u00e9 z\u00e1soby vody.<\/p>\n

Pov\u011bst o sv\u011btov\u00e9 potop\u011b je jeden z nejdiskutovan\u011bj\u0161\u00edch biblick\u00fdch p\u0159\u00edb\u011bh\u016f. \u0158ada v\u011bdc\u016f v\u011b\u0159\u00ed, \u017ee se skute\u010dn\u011b odehr\u00e1la. A nejednou. Na v\u0161ech kontinentech jsou \u010detn\u00e9 zn\u00e1mky z\u00e1plav. Jezera se slanou vodou se nach\u00e1z\u00ed i tis\u00edce kilometr\u016f od pob\u0159e\u017e\u00ed \u2013 i ta jsou pova\u017eov\u00e1na za poz\u016fstatky d\u00e1vn\u00e9 potopy.<\/p>\n

Ale odkud se na Zemi vzalo tolik vody k tak katastrof\u00e1ln\u00ed glob\u00e1ln\u00ed povodni? K takov\u00e9, \u017ee praotec Noe p\u0159ist\u00e1l se svou archou na vrcholku hory Ararat?<\/p>\n

\"\"<\/p>\n

Hypot\u00e9z je cel\u00e1 \u0159ada. Do oce\u00e1nu mohl spadnout asteroid nebo kometa, co\u017e by zp\u016fsobilo obrovsk\u00e9 tsunami. Nebo rozt\u00e1l led v d\u016fsledku glob\u00e1ln\u00edho oteplov\u00e1n\u00ed. Nebo naopak, chlad zp\u016fsobil zablokov\u00e1n\u00ed \u0159ek ledem, a \u00farove\u0148 vodn\u00ed hladiny v oce\u00e1nech dramaticky vzrostla. A n\u011bkte\u0159\u00ed v\u011bdci dokonce tvrd\u00ed, \u017ee osa planety se posunula, a v d\u016fsledku toho p\u0159esuny vod postupovaly ve vln\u00e1ch o v\u00fd\u0161ce n\u011bkolika kilometr\u016f.<\/p>\n

Nicm\u00e9n\u011b, a\u017e do ned\u00e1vn\u00e9 doby neexistovaly solidn\u00ed v\u011bdeck\u00e9 d\u016fkazy, kter\u00e9 by se mohly op\u0159\u00edt o spolehliv\u00e1 fakta.<\/p>\n

Nyn\u00ed byly publikov\u00e1ny v \u010dasopise Nature v\u00fdsledky senza\u010dn\u00ed studie. D\u00edky nim se hypot\u00e9za, kter\u00e1 byla d\u0159\u00edve pova\u017eov\u00e1na za \u00fapln\u011b bl\u00e1znivou, stala velice re\u00e1lnou. Jde o hypot\u00e9zu, \u017ee voda p\u0159i potop\u011b p\u0159i\u0161la z nitra Zem\u011b. Nyn\u00ed to u\u017e opravdu nen\u00ed fantazie – uvnit\u0159 na\u0161\u00ed planety se nach\u00e1z\u00ed obrovsk\u00e9 z\u00e1sob\u00e1rny vody. Je j\u00ed v nich tolik, \u017ee by to sta\u010dilo k napln\u011bn\u00ed deseti oce\u00e1n\u016f, nap\u0159\u00edklad v Pacifiku.<\/p>\n

\"\"<\/p>\n

Tajemstv\u00ed sv\u011btov\u00e9 potopy byla skryta uvnit\u0159 diamantu.<\/p>\n

Je to vlastn\u011b \u00fapln\u011b mal\u00fd diamant – v\u00e1\u017e\u00ed m\u00e9n\u011b ne\u017e jednu desetinu gramu. Byl nalezen v Braz\u00edlii. Je zn\u00e1mo, \u017ee diamanty vznikaj\u00ed ve velk\u00fdch hloubk\u00e1ch – v\u00edce ne\u017e 500 km.<\/p>\n

Geologick\u00fdmi procesy se dostal na povrch. Ale co je nejd\u016fle\u017eit\u011bj\u0161\u00ed: diamant v sob\u011b obsahuje p\u0159ekvapiv\u00fd n\u00e1lez – mal\u00fd miner\u00e1ln\u00ed krystal ringwoodit (1). Je hermeticky „uzav\u0159en“, a proto je ve stejn\u00e9m stavu, v jak\u00e9m byl v hloubce. A tak poskytuje vz\u00e1cnou p\u0159\u00edle\u017eitost: zjistit, jak\u00e9 bylo prost\u0159ed\u00ed, ve kter\u00e9m vznikl.<\/p>\n

Anal\u00fdza, proveden\u00e1 t\u00fdmem v\u011bdc\u016f pod veden\u00edm geochemika Grahama Pearson (2) z kanadsk\u00e9 univerzity v Albert\u011b (University of Alberta v Edmontonu), uk\u00e1zala, \u017ee v krystalu ringwooditu je p\u016fl procenta vody. To znamen\u00e1, \u017ee vznikal obklopen vodou.<\/p>\n

Podle st\u00e1vaj\u00edc\u00edch p\u0159edstav, ringwoodite – hlavn\u00ed slo\u017eka tzv. p\u0159echodov\u00e9 z\u00f3ny Zem\u011b – se nach\u00e1z\u00ed v hloubce n\u011bkolika set kilometr\u016f.<\/p>\n

P\u0159ed n\u011bkolika lety hovo\u0159ili o podzemn\u00edch oce\u00e1nech ameri\u010dt\u00ed v\u011bdci pod veden\u00edm Michaela Wysession (3), profesora seismologie na Washington University v St. Louis.<\/p>\n

Nalezli je p\u0159i studiu seismogramy – z\u00e1znamov\u00fdch charakteristik zem\u011bt\u0159esen\u00ed.<\/p>\n

Anal\u00fdza p\u0159ibli\u017en\u011b 600.000 seismogram\u016f je p\u0159ekvapila. Zd\u00e1 se, \u017ee alespo\u0148 ve dvou m\u00edstech – pod v\u00fdchodn\u00ed \u010d\u00e1st\u00ed euroasijsk\u00e9ho kontinentu a pod Severn\u00ed Amerikou se nach\u00e1z\u00ed obrovsk\u00e9 vodn\u00ed n\u00e1dr\u017ee<\/p>\n

A je\u0161t\u011b p\u0159edt\u00edm mo\u0159skou vodou pod povrchem Zem\u011b objevili brit\u0161t\u00ed v\u011bdci z University v Manchesteru. Rozpoznali jej\u00ed stopy v oxidu uhli\u010dit\u00e9m, unikaj\u00edc\u00edm z hloubky asi 1500 kilometr\u016f. Nikdo jim nev\u011b\u0159il. Ale zd\u00e1 se, \u017ee nyn\u00ed ten d\u016fkaz existuje.<\/p>\n

Jak se voda dostala dovnit\u0159 Zem\u011b, nen\u00ed zn\u00e1mo, – je mo\u017en\u00e9, \u017ee vznikla spolu s planetou. To znamen\u00e1, \u017ee tam v\u017edycky byla. Nebo se tam dostala z povrchu, kde bylo vody d\u0159\u00edve mnohem v\u00edce ne\u017e nyn\u00ed. Mo\u017en\u00e1, \u017ee cel\u00e1 planeta byla kdysi jeden velk\u00fd oce\u00e1n. Jako Jupiter\u016fv m\u011bs\u00edc Europa.<\/p>\n

Existuje teorie, podle kter\u00e9 hlubinn\u00e1 voda p\u0159ich\u00e1z\u00ed na povrch Zem\u011b pravideln\u011b. A pak znovu nate\u010de do podzem\u00ed. V\u011bdecky vzato, objem zemsk\u00e9 hydrosf\u00e9ry se m\u011bn\u00ed.

Mimochodem, na dn\u011b oce\u00e1nu jsou podivn\u00e9 otvory, ze kter\u00fdch proud\u00ed voda o teplot\u011b 400 stup\u0148\u016f. Naz\u00fdvaj\u00ed se „\u010dern\u00e9 kom\u00edny“.<\/p>\n

\"\"<\/p>\n

Je mo\u017en\u00e9, \u017ee v d\u00e1vn\u00fdch dob\u00e1ch podzemn\u00ed n\u00e1dr\u017ee praskly. Vznikly gejz\u00edry hork\u00fdch, slan\u00fdch vodn\u00edch par, jako kdy\u017e praskne kotel. Glob\u00e1ln\u00ed mo\u0159sk\u00e1 hladina se zv\u00fd\u0161ila, a d\u00e9\u0161\u0165 ze zkondenzovan\u00fdch par trval 40 dn\u016f a 40 noc\u00ed. Tak vznikla Sv\u011btov\u00e1 potopa. A pak voda natekla zp\u011bt.<\/p>\n

To znamen\u00e1, alespo\u0148 teoreticky, \u017ee se takov\u00e1 katastrofick\u00e1 ud\u00e1lost m\u016f\u017ee st\u00e1t znovu. A to i takov\u00e1, \u017ee ani ten Ararat nebude vid\u011bt. Je mo\u017en\u00e9, \u017ee i pod oce\u00e1ny, tedy tam, kde se dosud seismicky p\u0159\u00edli\u0161 nezkoumalo \u2013 jsou oblasti pln\u00e9 vody.
