Stopy v\u00fdbuch\u016f z kosmu jsou zachyceny v letokruz\u00edch strom\u016f.<\/strong><\/p>\n

Skupina japonsk\u00fdch v\u011bdc\u016f z University v Nagoya (Nagoya University)<\/em> pod veden\u00edm profesora Fusa Miyake<\/em>, zkoumala letokruhy star\u00fdch cedr\u016f, kter\u00e9 rostly v Evrop\u011b.<\/p>\n

Zjistili, \u017ee ve st\u0159edov\u011bku cedry zachytily siln\u00fd energetick\u00fd tok, v jeho\u017e d\u016fsledku obsah radioaktivn\u00edho izotopu uhl\u00edku C14 vzrostl 20 kr\u00e1t!<\/p>\n

Podle odpo\u010dtu letokruh\u016f Japonci ur\u010dili, \u017ee k tomu do\u0161lo v roce 775 n.l. V\u011bdci uve\u0159ejnili v\u00fdsledky m\u011b\u0159en\u00ed v \u010dasopise Nature.<\/em><\/p>\n

Prvn\u00ed dva zdroje, samoz\u0159ejm\u011b odpadaj\u00ed: v osm\u00e9m stolet\u00ed nedo\u0161lo k \u017e\u00e1dn\u00fdm hav\u00e1ri\u00edm jadern\u00fdch elektr\u00e1ren, ani nevybuchly atomov\u00e9 bomby.<\/p>\n

Zb\u00fdv\u00e1 kosmos…<\/strong><\/p>\n

Zem\u011b se tedy musela dostat p\u0159ed 1200 lety do cesty n\u011bjak\u00e9 kosmick\u00e9 katastrofy, a byla bombardov\u00e1na kosmick\u00fdmi paprsky. Ale co bylo zdrojem, to se japonsk\u00fdm v\u011bdc\u016fm nepoda\u0159ilo zjistit.<\/p>\n

Oza\u0159ovat Zemi m\u016f\u017ee t\u0159eba Slunce. Ale to by musela b\u00fdt s\u00edla, kter\u00e1 by zni\u010dila ozonovou vrstvu a zp\u016fsobila pol\u00e1rn\u00ed z\u00e1\u0159i na cel\u00e9 planet\u011b.<\/p>\n

A to by nepro\u0161lo bez pov\u0161imnut\u00ed kronik\u00e1\u0159\u016fm t\u00e9 doby – lid\u00e9 bedliv\u011b sledovali podivnosti a zaznamen\u00e1vali anom\u00e1lie. Ale takov\u00e1 sv\u011bdectv\u00ed z t\u00e9 doby nejsou.<\/p>\n

Ale i to by museli lid\u00e9 vid\u011bt. Starov\u011bc\u00ed astronomov\u00e9 nap\u0159\u00edklad uv\u00e1d\u011bj\u00ed v\u00fdbuchy supernov, kter\u00e9 nastaly v roce 1006 a 1056.

Dokonce i stopy po takov\u00e9 explozi by dnes astronomov\u00e9 na\u0161li i po takov\u00e9 dob\u011b s pomoc\u00ed modern\u00edch infra\u010derven\u00fdch a rentgenov\u00fdch teleskop\u016f.<\/p>\n

Pot\u00e9, co Japonci zkoumali d\u0159evo star\u00fdch cedr\u016f, prov\u011b\u0159ili vzorky z\u00edskan\u00e9 z ledovc\u016f.

\u201eNedovedu si p\u0159edstavit takov\u00fd v\u00fdbuch supernovy, nehled\u011b na to, \u017ee by musel b\u00fdt velmi jasn\u00fd,\u201c<\/em> \u0159ekl v\u011bdec \u010dasopisu New Scientist. \u201eNav\u00edc, muselo b\u00fdt n\u011bkolik takov\u00fdch z\u00e1blesk\u016f, cel\u00e1 s\u00e9rie v mal\u00e9 vzd\u00e1lenosti.\u201c<\/em><\/p>\n

Podle Jonathona Allena,<\/em> studenta Kalifornsk\u00e9 univerzity se jednalo o supernovu, o kter\u00e9 je zm\u00ednka v tzv. Anglosask\u00e9 kronice<\/em>. Podle textu se v roce 774 na obloze nad Angli\u00ed po z\u00e1padu Slunce objevil \u201erud\u00fd k\u0159\u00ed\u017e\u201c.<\/p>\n

\u010cerven\u00e1 barva jevu podle n\u011bj m\u016f\u017ee nazna\u010dovat, \u017ee by se hv\u011bzda mohla nach\u00e1zet za prachov\u00fdm mra\u010dnem. P\u0159es n\u011bj by byl poz\u016fstatek t\u00e9to supernovy (t\u0159eba neutronov\u00e1 hv\u011bzda) dnes jen t\u011b\u017eko pozorovateln\u00fd. A to by vysv\u011btlovalo, pro\u010d se na hv\u011bzdn\u00fdch map\u00e1ch neobjevuje \u017e\u00e1dn\u00fd vhodn\u00fd kandid\u00e1t na v\u00fdbuch v dob\u011b kolem roku 775.<\/p>\n

Volba slov v kronice by tak\u00e9 snad mohla nazna\u010dovat, \u017ee objekt se na obloze objevil kr\u00e1tce po z\u00e1padu Slunce. To by pak znamenalo, \u017ee b\u011bhem dn\u00ed \u010di t\u00fddn\u016f n\u00e1sleduj\u00edc\u00edch po zm\u00edn\u011bn\u00e9m pozorov\u00e1n\u00ed by hypotetickou supernovu pozemsk\u00fdm pozorovatel\u016fm zakrylo Slunce. To by mohlo vysv\u011btlovat, pro\u010d ji nezaznamenal \u017e\u00e1dn\u00fd pisatel krom\u011b autora(\u016f) Anglosask\u00e9 kroniky. (podle: technet.idnes)<\/em><\/p>\n

Ufologov\u00e9, zab\u00fdvaj\u00edc\u00ed se d\u00e1vnou astronautikou, rozvinuli my\u0161lenku Igora Moskalenka<\/em> po sv\u00e9m. A navrhli \u0159e\u0161en\u00ed: u Zem\u011b se odehr\u00e1ly jak\u00e9si \u201ehv\u011bzdn\u00e9 v\u00e1lky<\/em>\u201c. Zem\u011b zachytila z\u00e1blesky v\u00fdst\u0159el\u016f, kter\u00e9 po sob\u011b p\u00e1lily kosmick\u00e9 lod\u011b v\u00e1l\u010d\u00edc\u00edch civilizac\u00ed.<\/p>\n

Existuje v\u0161ak i m\u00e9n\u011b bojovn\u00e1 hypot\u00e9za. Ta je zalo\u017eena na studi\u00edch americk\u00e9ho astronoma Harrise,<\/em> kter\u00fd se v roce 1986 sna\u017eil dok\u00e1zat, \u017ee gama z\u00e1blesky – a dlouh\u00e9 a kr\u00e1tk\u00e9 \u2013 jsou v\u00fdsledkem pohybu kosmick\u00fdch lod\u00ed, s pohonem na antihmotu.<\/p>\n

Gama-z\u00e1\u0159en\u00ed se objev\u00ed v d\u016fsledku styku antihmoty s na\u0161\u00ed, oby\u010dejnou, hmotou \u2013 dojde k anihilaci. Kosmick\u00e1 lo\u010f, pou\u017e\u00edvaj\u00edc\u00ed tuto energii ke sv\u00e9mu pohybu, \u010das od \u010dasu vyvol\u00e1v\u00e1 takov\u00e9 exploze.<\/p>\n

Harris se dokonce pokusil dohledat \u0159adu gama z\u00e1blesk\u016f, kter\u00e9 le\u017e\u00ed v jedn\u00e9 linii. V\u011b\u0159il, \u017ee jde o dr\u00e1hu letu ciz\u00ed kosmick\u00e9 lodi.

Tak\u017ee je mo\u017en\u00e9, \u017ee p\u0159ed 1237 lety se Zem\u011b dotkla emise ciz\u00ed kosmick\u00e9 lodi?<\/p>\n","protected":false},"excerpt":{"rendered":"
