V Brit\u00e1nii v\u011bdci z Cornell University odpov\u011bd\u011bli na ot\u00e1zku, pro\u010d jsme je\u0161t\u011b nena\u0161li mimozem\u0161\u0165any.<\/strong><\/p>\n

Sv\u00e9 z\u00e1v\u011bry publikovali fyzici ve v\u011bdeck\u00e9m \u010dasopise Proceedings of the Royal Society of London A.<\/em><\/p>\n

Abychom pochopili, pro\u010d se lidstvu neda\u0159\u00ed komunikovat s jin\u00fdmi sv\u011bty, v\u011bdci provedli sv\u00e9 v\u00fdpo\u010dty a vzorce. I kdy\u017e nep\u0159inesli nic nov\u00e9ho, zam\u011b\u0159ili se na detaily, kter\u00e9 jejich p\u0159edch\u016fdci pom\u00edjeli.<\/p>\n

P\u0159ed v\u00edce ne\u017e p\u016fl stolet\u00edm byl vytvo\u0159en vzorec, pomoc\u00ed n\u011bho\u017e m\u016f\u017eeme vypo\u010d\u00edtat, kolik civilizac\u00ed je v Galaxii. Tento vzorec zformuloval astronom Frank Drake.<\/em> (2)<\/p>\n

Podle jeho v\u00fdpo\u010dt\u016f bylo jasn\u00e9, \u017ee \u0161ance na hled\u00e1n\u00ed jin\u00e9ho \u017eivota a kontakt s n\u00edm, jsou skv\u011bl\u00e9.<\/p>\n

P\u0159esto t\u00edm nebyl vy\u0159e\u0161en Fermiho paradox.<\/em> Fyzik Enrico Fermi<\/em> (3) kdysi polo\u017eil skeptickou ot\u00e1zku: pokud existuje tolik mimozemsk\u00fdch civilizac\u00ed, pro\u010d jsme o tom zat\u00edm nenalezli d\u016fkazy?<\/p>\n

Fyzici Cornell University<\/em> upozornili na to, \u017ee ve v\u00fdpo\u010dtech, zalo\u017een\u00fdch na formulaci Drakeova vzorce<\/em>, \u0159ada v\u011bdc\u016f vych\u00e1z\u00ed z nep\u0159esn\u00fdch \u00fadaj\u016f. Z tohoto d\u016fvodu je v\u00fdsledkem rovnice n\u011bjak\u00e1 „konkr\u00e9tn\u00ed“ cifra, bl\u00edzk\u00e1 po\u017eadovan\u00e9mu p\u0159\u00e1n\u00ed, a nikoli velk\u00fd soubor r\u016fzn\u00fdch variant odpov\u011bd\u00ed.<\/p>\n

Brit\u0161t\u00ed v\u011bdci vypo\u010d\u00edtali znovu Drakeovu rovnici, s p\u0159ihl\u00e9dnut\u00edm v\u0161ech chyb. Vzali v \u00favahu takov\u00e9 rysy, jako je doba existence civilizac\u00ed, \u010das pro vznik hv\u011bzd, po\u010det hv\u011bzd s planetami a kosmick\u00fdmi objekty, podobn\u00fdmi Zemi.<\/p>\n

Fyzici tyto v\u00fdpo\u010dty kombinovali pomoc\u00ed statistick\u00fdch \u00fadaj\u016f a zjistili, \u017ee 30% v\u00fdsledk\u016f ukazuje, \u017ee v Galaxii<\/em> nejsou jin\u00e9 civilizace. \u010c\u00e1st v\u00fdsledk\u016f ukazuje vysok\u00fd po\u010det civilizac\u00ed, jako tomu bylo u p\u0159edchoz\u00edch v\u00fdpo\u010dt\u016f.<\/p>\n

Brit\u0161t\u00ed v\u011bdci tedy do\u0161li k z\u00e1v\u011bru, \u017ee Fermiho paradox prost\u011b nem\u00e1 smysl. Absence viditeln\u00fdch civilizac\u00ed lze vysv\u011btlit Drakeov\u00fdm vzorcem.<\/p>\n

Pravd\u011bpodobnost, \u017ee se lid\u00e9 mohou v budoucnu setkat s jin\u00fdm \u017eivotem, nebo \u017ee\u00a0 existoval v minulosti, tu ale st\u00e1le je\u0161t\u011b je.<\/p>\n
