Lidstvo zauj\u00edm\u00e1 velmi skromn\u00e9 m\u00edsto, a to nejen ve vesm\u00edru, ale tak\u00e9 ve sv\u00e9 domovsk\u00e9 Galaxii – Ml\u00e9\u010dn\u00e9 dr\u00e1ze.<\/strong>
\nJeho m\u00edsto uk\u00e1zal astronom Adam Grossman<\/em> na sv\u00e9m blogu – malou \u017elutou te\u010dku. (1)<\/p>\n

Jej\u00ed pr\u016fm\u011br je pouh\u00fdch 234 sv\u011bteln\u00fdch let – je to opravdu mr\u0148ous v porovn\u00e1n\u00ed s celou galaktickou spir\u00e1lou o pr\u016fm\u011bru v\u00edce ne\u017e 100 tis\u00edc sv\u011bteln\u00fdch let.<\/p>\n

Bod, nebo jak se tomu \u0159\u00edk\u00e1 Grossman, „bublina lidstva<\/em>„, je oblast, jej\u00ed\u017e hranice je d\u00e1na prvn\u00ed vys\u00edl\u00e1n\u00edm radia v roce 1895.<\/p>\n

Od t\u00e9 doby se um\u011bl\u00e9 elektromagnetick\u00e9 sign\u00e1ly \u0161\u00ed\u0159\u00ed v\u0161emi sm\u011bry do vesm\u00edru rychlost\u00ed sv\u011btla. S touto rychlost\u00ed se roz\u0161i\u0159uje sf\u00e9ra, napln\u011bn\u00e1 t\u011bmito sign\u00e1ly. Napl\u0148uje prostor, kde tyto sign\u00e1ly m\u016f\u017ee n\u011bkdo sly\u0161et. Nebo alespo\u0148 pochopit, \u017ee bylo zachyceno n\u011bco um\u011bl\u00e9ho.<\/p>\n

Pokud ov\u0161em v tomto prostoru existuje odpov\u00eddaj\u00edc\u00ed druh vyn\u00e1lezu r\u00e1dia. Nemluv\u011b o radioteleskopu.<\/p>\n

I kdy\u017e se „bublina lidstva<\/em>“ zd\u00e1 velk\u00e1, sv\u011bty, kter\u00e9 jsou v\u00edce vzd\u00e1len\u00e9, nemohou v\u011bd\u011bt o na\u0161\u00ed existenci.<\/p>\n

Na na\u0161e vys\u00edl\u00e1n\u00ed zat\u00edm nikdo neodpov\u011bd\u011bl. Tak\u00e9 v\u011bdci st\u00e1le je\u0161t\u011b nezachytili nic povzbudiv\u00e9ho \u2013 \u017e\u00e1dn\u00e9 mimozemsk\u00e9 r\u00e1dio nebo alespo\u0148 n\u011bkter\u00e9 um\u011bl\u00e9 sign\u00e1ly.<\/p>\n

Znamen\u00e1 to, \u017ee mimozem\u0161\u0165an\u00e9 v na\u0161\u00ed „bublin\u011b“<\/em> nejsou? Adam Grossman napsal, \u017ee se c\u00edt\u00ed velmi osam\u011bl\u00fd.<\/p>\n

Je p\u0159\u00edli\u0161 pozd\u011b se schovat\u2026<\/strong><\/p>\n

Seth Shostak<\/em>, vedouc\u00ed programu pro hled\u00e1n\u00ed sign\u00e1l\u016f mimozemsk\u00fdch civilizac\u00ed, se domn\u00edv\u00e1, \u017ee je p\u0159\u00edli\u0161 pozd\u011b se schovat. „Bublina lidstva<\/em>“ pro n\u011bj ve skute\u010dnosti nen\u00ed zase tak mal\u00e1.<\/p>\n

R\u00e1diov\u00e9 vlny ze Zem\u011b od po\u010d\u00e1tku \u00e9ry jej\u00edho vys\u00edl\u00e1n\u00ed, zas\u00e1hly p\u0159es 6000 hv\u011bzdn\u00fdch syst\u00e9m\u016f.<\/p>\n

A ka\u017ed\u00fd den sign\u00e1ly lidsk\u00e9 civilizace zasahuj\u00ed minim\u00e1ln\u011b jeden nov\u00fd hv\u011bzdn\u00fd syst\u00e9m.<\/p>\n

Je nepravd\u011bpodobn\u00e9, \u017ee mimozem\u0161\u0165an\u00e9 – i vysp\u011blej\u0161\u00ed ne\u017e my – poslouchaj\u00ed na\u0161e r\u00e1dio nebo sleduj\u00ed na\u0161i televizi. Se vzr\u016fstaj\u00edc\u00ed vzd\u00e1lenost\u00ed je sign\u00e1l u\u017e siln\u011b zkreslen\u00fd. Ale mohou rozpoznat v sign\u00e1lech um\u011bl\u00fd p\u016fvod a ur\u010dit jeho polohu. Podle Shostaka lidsk\u00e1 technika n\u011bco takov\u00e9ho bude schopn\u00e1 za sto, dv\u011b st\u011b let. Jinak \u0159e\u010deno, u\u017e jsme d\u00e1vno v\u0161e uk\u00e1zali na\u0161i polohu. A budeme v tom pokra\u010dovat, i kdy\u017e bychom nyn\u00ed snad u\u017e necht\u011bli\u2026<\/p>\n

Shostak\u016fv n\u00e1zor sd\u00edl\u00ed i vedouc\u00ed v\u00fdzkumu \u00dastavu radiotechniky a elektroniky RAV, doktor fyzik\u00e1ln\u00edch a matematick\u00fdch v\u011bd, Alexander Zajcev.<\/em><\/p>\n

\u201eNemysl\u00edm si, \u017ee by se m\u011bli pozem\u0161\u0165an\u00e9 p\u0159ed n\u011bk\u00fdm schov\u00e1vat,\u201c<\/em> \u0159\u00edk\u00e1.<\/p>\n

\u201ePokud budeme p\u0159edpokl\u00e1dat, \u017ee existuje siln\u00e1 agresivn\u00ed civilizace, daleko p\u0159ed n\u00e1mi, tak se p\u0159ed n\u00ed neschov\u00e1me.<\/em><\/p>\n

Pokud jejich technika je vyvinuta tak, \u017ee by mohli za\u00fato\u010dit na Zemi, znamen\u00e1 to, \u017ee u\u017e d\u00e1vno zjistili na\u0161e r\u00e1diov\u00e9 vlny – nap\u0159\u00edklad na\u0161e TV se satelitn\u00edm p\u0159\u00edjmem – a v\u0161echno o n\u00e1s v\u00ed.<\/em><\/p>\n

Z druh\u00e9 strany, pokud sign\u00e1ly zachytila civilizace na stejn\u00e9 \u00farovni s n\u00e1mi, pak, pokud s n\u00ed nav\u00e1\u017eeme r\u00e1diov\u00fd kontakt, nejsme nijak ohro\u017eeni.<\/em><\/p>\n

Ani na\u0161e, ani jejich technika nen\u00ed schopna dolet\u011bt od jedn\u00e9 hv\u011bzdy k druh\u00e9 v relativn\u011b kr\u00e1tk\u00e9m \u010dase.\u201c<\/em><\/p>\n
