Šta se to dešava???
Veliki hadronski kolajder (LHC), akcelerator koji su gradili vodeći
fizičari planete u Centralnoj evropskoj laboratoriji za nuklearna
istraživanja (CERN) i preko 2.000 istraživača sa nekoliko stotina
fakulteta iz celog sveta i laboratorija iz 34 zemlje, biće isproban
etapno. Naučnici se nadaju da će im taj uređaj omogućiti da dobiju verodostojne informacije o nastanku univerzuma. Oni pretpostavljaju da će pomoću njega ponovo stvoriti uslove kakvi su postojali jedan trilioniti deo sekunde posle Velikog praska.
Kolajder se nalazi u džinovskom tunelu na dubini od 100 metara i
prečnika 27 kilometara. Dva snopa čestica će se kretati suprotnim
smerovima velikom brzinom. Međutim, njihove putanje će se na mnogi
mestima presecati i sudarati. Čestice će usmeravati nekoliko hiljada
superprovodljivih magneta. Upravo će posledice tih sudara biti glavni
predmet istraživanja naučnika. Ukoliko se sve bude odvijalo po planu, prvi protoni će početi da kruže po celom akceleratoru 2. ili 3. septembra.
Posle toga inženjeri procenjuju
da će im biti potrebno mesec-dva da bi doterali i podesili intenzitet
snopova pre nego što dozvole njihovo sudaranje i proizvodnju čestica
koje su dovele do nastanka univerzuma.
CERN će zatvoriti
akcelerator tokom zime da bi se uštedela struja, a u međuvremenu čitava
armija fizičara koji su sagradili dva džinovska detektora čestica ATLAS
i CMS pripremaće se za veliki događaj, to jest aktiviranje celog
Velikog hadronskog kolajdera 21. oktobra.
Za Veliki hadronski
kolajder vezane su brojne priče i legende. Na primer, postoji mišljenje
da bi u akceleratoru mogle da se pojave crne rupe, koje bi uništile ne
samo mašinu već i pola teritorije Francuske i Švajcarske i - na kraju -
našu planetu.
Naučnici tvrde da je tako nešto u principu moguće,
ali da bi te rupe postojale suviše kratko, to jest nekoliko delića
sekunde, da bi nanele bilo kakvu štetu. Osim toga, dodaju oni,
sudaranje subatomskih čestica, slično onome koje će izazvati kolajder,
konstantno se dešava u prirodi, a sudari čestica kosmičkog zračenja
proizvode mnogo više energije od kolajdera.
„Sasvim je očigledno da neće biti smaka sveta kad uključimo naš akcelerator“, ističe Lin Evans, šef projekta CERN.
