Lid\u00e9 byli v\u017edy fascinov\u00e1ni mo\u017enost\u00ed \u017eivota mimo Zemi.

Fermiho paradox<\/h2>\n\n

Navzdory obrovsk\u00e9 velikosti vesm\u00edru a vysok\u00e9 pravd\u011bpodobnosti mimozemsk\u00e9ho \u017eivota podle Drakeovy rovnice jsme je\u0161t\u011b nena\u0161li \u017e\u00e1dn\u00e9 definitivn\u00ed d\u016fkazy inteligentn\u00edch mimozemsk\u00fdch civilizac\u00ed.

V\u011bdci a politici si uv\u011bdomili pot\u0159ebu p\u0159ipravit se na mo\u017enost objeven\u00ed mimozemsk\u00e9ho \u017eivota. V roce 1993 vypracovala skupina v\u011bdc\u016f “Deklaraci princip\u016f t\u00fdkaj\u00edc\u00edch se prov\u00e1d\u011bn\u00ed hled\u00e1n\u00ed mimozemsk\u00e9 inteligence”.
