Keby dnes vedci ohl\u00e1sili, \u017ee zaru\u010dene a nespochybnite\u013ene na\u0161li \u017eivot na inej plan\u00e9te, bol by to najv\u00e4\u010d\u0161\u00ed objav v hist\u00f3rii \u013eudstva<\/strong>. Znamenal by nielen otrasenie mnoh\u00fdmi n\u00e1bo\u017eenstvami, ale vytvoril by \u00faplne nov\u00e9 etick\u00e9, mor\u00e1lne i filozofick\u00e9 ot\u00e1zky, razom by sa do vesm\u00edrneho v\u00fdskumu investovalo nepomerne viac ako kedyko\u013evek doteraz. Len\u017ee aj napriek tomu, \u017ee vesm\u00edrny v\u00fdskum u\u017e dnes stoj\u00ed miliardy a miliardy dol\u00e1rov a pracuj\u00fa na \u0148om najkvalitnej\u0161\u00ed a najschopnej\u0161\u00ed \u013eudia na svete, nepodarilo sa n\u00e1js\u0165 \u017eiadny skuto\u010dn\u00fd d\u00f4kaz o existencii inteligentn\u00e9ho \u017eivota mimo na\u0161ej plan\u00e9ty.<\/p>\n

 <\/p>\n

\u0160tatistika ale hovor\u00ed v prospech \u017eivota mimo Zeme. U\u017e dnes vieme, \u017ee ka\u017ed\u00e1 galaxia obsahuje minim\u00e1lne jednu miliardu hviezd<\/strong> a v na\u0161om pozorovate\u013enom vesm\u00edre je aspo\u0148 jedna miliarda galaxi\u00ed<\/strong>. A \u010fal\u0161ie mimo n\u00e1\u0161 dosah. To s\u00fa po\u010dty, ktor\u00e9 sa \u010dloveku iba ve\u013emi \u0165a\u017eko predstavuj\u00fa, nie e\u0161te ch\u00e1pu.<\/p>\n

Zdroje uv\u00e1dzaj\u00fa, \u017ee ot\u00e1zku \u201eKde s\u00fa v\u0161etci?\u201c polo\u017eil Enrico Fermi<\/strong> po\u010das obed\u0148aj\u0161ej prest\u00e1vky s fyzikmi Emilom Konopinskim, Edwardom Tellerom a Herbertom Yorkom v roku 1950 v Los Alamos. \u201eUpozornil na to, \u017ee aj napriek tomu, \u017ee vesm\u00edr je relat\u00edvne dos\u0165 star\u00fd, nenach\u00e1dzame v Mlie\u010dnej ceste \u017eiadne stopy po mimozemsk\u00fdch civiliz\u00e1ci\u00e1ch, ak\u00fdmi by boli napr\u00edklad stopy po raketov\u00fdch technol\u00f3gi\u00e1ch alebo r\u00e1diovom vysielan\u00ed<\/em>.\u201c (zdroj)<\/p>\n

Fermi m\u00e1 pravdu v tom, \u017ee vesm\u00edr je dos\u0165 star\u00fd na to, aby umo\u017enil rozkvet inteligentn\u00e9ho \u017eivota a v\u00fdvoju n\u00e1ro\u010dn\u00fdch technol\u00f3gi\u00ed. Je pod\u013ea neho naivn\u00e9 myslie\u0165 si, \u017ee sa \u017eivot mohol vyvin\u00fa\u0165 jedine v takej forme a v takom \u010dase, ak\u00fd pozn\u00e1me tu na Zemi. Ak ale \u017eivot mohol vznikn\u00fa\u0165 a vyv\u00edja\u0165 sa aj inde, mal by zanecha\u0165 po sebe aspo\u0148 nejak\u00e9 stopy – ak u\u017e nie je vidite\u013en\u00e9, tak aspo\u0148 vo forme r\u00e1diov\u00fdch v\u013an, ktor\u00e9 by boli jednozna\u010dne identifikovate\u013en\u00e9 ako vytvoren\u00e9 z\u00e1merne. A tak\u00fdchto \u017eivotov mohli zo \u0161tatistick\u00e9ho h\u013eadiska vznika\u0165 tis\u00edce \u010di mili\u00f3ny. Pre\u010do teda dodnes nevieme ani o jednom z nich? Kde s\u00fa v\u0161etci t\u00ed mimozem\u0161\u0165ania?<\/em><\/p>\n

 <\/p>\n

Paradox n\u00e1m pon\u00faka tri z\u00e1kladn\u00e9 odpovede, pre\u010do dodnes o \u017eivote mimo Zeme nevieme:<\/p>\n

    \n
  1. Mimozem\u0161\u0165ania neexistuj\u00fa, \u017eivot na Zemi je jedine\u010dn\u00fd a vz\u00e1cny vo Vesm\u00edre. T\u00e1to\u00a0<\/strong><\/li>\n
  2. Mimozemsk\u00e9 civiliz\u00e1cie existuj\u00fa, ale e\u0161te nedo\u0161lo ku komunik\u00e1cii s nami.<\/strong><\/li>\n
  3. Z\u00e1stupcovia mimozemskej civiliz\u00e1cie s\u00fa u\u017e na Zemi.<\/strong><\/li>\n<\/ol>\n

     <\/p>\n \u013dudstvo po sebe zanech\u00e1va stopy vo vesm\u00edre u\u017e cel\u00e9 desa\u0165ro\u010dia. S\u00fa to r\u00e1diov\u00e9 sign\u00e1ly, predmety vypusten\u00e9 do vesm\u00edru a ovplyv\u0148ovanie kl\u00edmy Zeme. Ak existuje \u017eivot mimo Zeme, pre\u010do o tak\u00fdchto prejavoch zatia\u013e nevieme? P\u00fdta sa na to Fermiho paradox.\n

    V prvom variante paradox (paradoxne) po\u010d\u00edta s t\u00fdm, \u017ee by sa mohol niekde vo vesm\u00edre vyskytova\u0165 \u017eivot, ale vo ve\u013emi primit\u00edvnej forme, ktor\u00e1 sa nikdy nestihla vyvin\u00fa\u0165 do inteligentn\u00e9ho \u017eivota. \u010ci u\u017e pre vlastn\u00fa neschopnos\u0165 \u010deli\u0165 prek\u00e1\u017ekam, pre pr\u00edrodn\u00fa katastrofu alebo \u010doko\u013evek in\u00e9 n\u00e1s tento \u017eivot nestihol kontaktova\u0165 alebo inak sa prejavi\u0165.<\/p>\n

    Druh\u00fd variant po\u010d\u00edta preva\u017ene s \u013eudsk\u00fdmi probl\u00e9mami. Aj my predsa existujeme, ale vesm\u00edrom necestujeme. Je to n\u00e1kladn\u00e9, n\u00e1ro\u010dn\u00e9, vyskytuj\u00fa sa tu nov\u00e9 etick\u00e9 ot\u00e1zky a probl\u00e9my (m\u00e1me v\u00f4bec pr\u00e1vo plodi\u0165 deti mimo Zeme?). Pr\u00edpadne je cestovanie vesm\u00edrom fyzik\u00e1lne nemo\u017en\u00e9, ak by sme chceli uva\u017eova\u0165 o prekon\u00e1van\u00ed v\u00fdznamnej\u0161\u00edch vzdialenost\u00ed v prijate\u013enom \u010dase.<\/p>\n

    Tret\u00ed variant je nepochybne ten najatrakt\u00edvnej\u0161\u00ed pre priaznivcov vedecko-fantastickej literat\u00fary a kon\u0161pira\u010dn\u00fdch te\u00f3rii, nemo\u017eno ho v\u0161ak ignorova\u0165. Po\u010d\u00edta s t\u00fdm, \u017ee mimozem\u0161\u0165ania u\u017e \u013eudstvo kontaktovali, ale vedia o tom iba vybran\u00ed \u013eudia, pr\u00edpadne s\u00fa pravdiv\u00e9 historky o hav\u00e1rii UFO, o \u00fanosoch \u013eud\u00ed a tak \u010falej.<\/p>\n

     <\/p>\n

    Fermiho paradox je zauj\u00edmav\u00fd a rozporupln\u00fd z\u00e1rove\u0148. Mnoh\u00ed s n\u00edm nes\u00fahlasia u\u017e len z podstaty, \u017ee ve\u010f ani my ned\u00e1vame vedie\u0165 o svojej pr\u00edtomnosti vo vesm\u00edre – nie je to v\u0161ak pravda. \u013dudstvo u\u017e cel\u00e9 desa\u0165ro\u010dia akt\u00edvne podnik\u00e1 kroky na to, aby vesm\u00edr o \u017eivote na Zemi vedel a navy\u0161e sa na\u0161a pr\u00edtomnos\u0165 vo vesm\u00edre prejavuje r\u00e1diov\u00fdmi vlnami, satelitmi na obe\u017enej dr\u00e1he Zeme a sondami za hranicou Slne\u010dnej s\u00fastavy (Voyager).<\/p>\n
