\u017d\u00e1dn\u00ed mimozem\u0161\u0165an\u00e9 nejsou, tvrd\u00ed skeptici a odkazuj\u00ed na slavn\u00fd Fermiho paradox.<\/em> (1)<\/strong><\/p>\n

Enrico Fermi<\/em> byl americk\u00fd fyzik italsk\u00e9ho p\u016fvodu, nositel Nobelovy ceny. Podle legendy, jednou v roce 1950 p\u0159i ob\u011bd\u011b poslouchal kolegy fyziky, kte\u0159\u00ed tvrdili, \u017ee mimozem\u0161\u0165an\u00e9 ve vesm\u00edru nejsou nic neobvykl\u00e9ho. A zeptal se jich: „Tak kde k \u010dertu jsou?“<\/em> Fyzici nena\u0161li odpov\u011b\u010f.<\/p>\n

Zd\u00e1nliv\u00fd rozpor – obrovsk\u00fd vesm\u00edr a nedostatek kontaktu s jeho obyvateli \u2013 je naz\u00fdv\u00e1n Fermiho paradox.<\/em><\/p>\n

Po \u010dtvrt stolet\u00ed p\u0159i\u0161el s dopl\u0148kem Angli\u010dan Michael Hart<\/em>. \u0158ekl, \u017ee pokud by existovaly tis\u00edce mimozemsk\u00fdch civilizac\u00ed, pak by se k n\u00e1m dostaly u\u017e p\u0159ed miliony let. No, alespo\u0148 n\u011bkter\u00e9.<\/p>\n

K dne\u0161n\u00edmu dni se v\u0161ak nikdo z jin\u00fdch sv\u011bt\u016f k n\u00e1m nedostal. Ani se s n\u00e1mi nikdo nekontaktoval.<\/p>\n

Alespo\u0148 o tom nen\u00ed \u017e\u00e1dn\u00fd nezpochybniteln\u00fd v\u011bdeck\u00fd d\u016fkaz. A to je, podle skeptik\u016f, nejp\u0159esv\u011bd\u010div\u011bj\u0161\u00ed argument ve prosp\u011bch skute\u010dnosti, \u017ee mimozem\u0161\u0165an\u00e9 – v\u016fbec neexistuj\u00ed.<\/p>\n

\u201eK n\u00e1m nikdo nikdy nep\u0159ilet\u011bl a nikdy nep\u0159ilet\u00ed,\u201c<\/em> – \u0159ekl p\u0159i t\u00e9to p\u0159\u00edle\u017eitosti profesor Simon Conway Morris, odborn\u00edk na teorii evoluce z Cambridge. (2) \u2013 \u201e\u0160ance, \u017ee mimozem\u0161\u0165an\u00e9 existuj\u00ed, je prakticky nulov\u00e1. A mnoz\u00ed jsou si toho dob\u0159e v\u011bdomi. A tak berou mimozem\u0161\u0165any jen jako legraci. \u010cist\u011b teoreticky.\u201c<\/em><\/p>\n

Mimozem\u0161\u0165an\u00e9 k n\u00e1m zkr\u00e1tka nep\u0159ilet\u00ed, proto\u017ee nejsou. Bohu\u017eel, skeptici mohou m\u00edt pravdu. A my jsme opravdu jedin\u00ed sv\u00e9ho druhu. Ned\u00e1vno to vyj\u00e1d\u0159il i astronom Dimitar Sasselov,<\/em> profesor z Harvardu, jeden z vedouc\u00edch v\u011bdeck\u00e9ho programu teleskopu Kepler. (3)<\/p>\n

Podle hrub\u00fdch odhad\u016f, jak v\u011bdec vysv\u011btluje – 1 miliardu let trvalo hv\u011bzd\u00e1m, je\u017e vznikly v ran\u00e9m vesm\u00edru, aby z prvotn\u00edho vod\u00edku a helia „vyrobily“ dostatek materi\u00e1lu pro vznik planet – kysl\u00edk, \u017eelezo, k\u0159em\u00edk, uhl\u00edk a dal\u0161\u00ed t\u011b\u017ek\u00e9 prvky.<\/p>\n

Je\u0161t\u011b pak v\u00edce ne\u017e 9 miliard let trvala tvorba a vytv\u00e1\u0159en\u00ed podm\u00ednek, vhodn\u00fdch pro \u017eivot. Ukazuje se, \u017ee Zem\u011b, kter\u00e1 je star\u00e1 asi 4,5 miliardy let, dob\u0159e zapad\u00e1 do tohoto \u010dasov\u00e9ho r\u00e1mce. A je mo\u017en\u00e9, \u017ee Zem\u011b nikoho nep\u0159edehnala ve sv\u00e9m v\u00fdvoji, a nikoho nepustila p\u0159ed sebe. Jin\u00fdmi slovy, je vysok\u00e1 pravd\u011bpodobnost, \u017ee na\u0161e planeta je prvn\u00ed, na kter\u00e9 vznikl \u017eivot. A my jsme prvn\u00ed inteligentn\u00ed bytosti ve vesm\u00edru.<\/p>\n

Sasselov v\u011b\u0159\u00ed, \u017ee \u010das, kter\u00fd je pot\u0159eba pro vznik i t\u011bch nejjednodu\u0161\u0161\u00edch organism\u016f, m\u016f\u017ee b\u00fdt roven se st\u00e1\u0159\u00edm vesm\u00edru. Proto, pokud budeme cht\u00edt n\u011bkde naj\u00edt mimozem\u0161\u0165any, pak s nejv\u011bt\u0161\u00ed pravd\u011bpodobnost\u00ed nebude jejich civilizace vyvinut\u011bj\u0161\u00ed ne\u017e na\u0161e. A mo\u017en\u00e1, \u017ee je na stejn\u00e9 \u00farovni, jako je ta na\u0161e. Tak\u017ee, mimozem\u0161\u0165an\u00e9 nemohli dorazit v minulosti. A je naivn\u00ed \u010dekat na n\u011b v bl\u00edzk\u00e9 budoucnosti. A ani oni n\u00e1s.<\/p>\n

To je \u0159e\u0161en\u00ed Fermiho paradoxu<\/em> \u2013 to \u00fapln\u011b nejjednodu\u0161\u0161\u00ed ze v\u0161ech \u0159e\u0161en\u00ed: vesm\u00edr je je\u0161t\u011b p\u0159\u00edli\u0161 mlad\u00fd, ne\u017e aby mohl b\u00fdt napln\u011bn \u017eivotem.<\/p>\n
