english: If we run the movie of our universe backwards, we know that there was a Big Bang in our past, and we might even hear the cacophonous sound of it, but was our Big Bang the only Big Bang?
non_english: Ak by sme spustili film nášho vesmíru odzadu, vedeli by sme, že v našej minulosti sa udial Veľký tresk a možno by sme mohli dokonca počuť aj jeho kakofonický zvuk. Bol však náš Veľký tresk jediným Veľkým treskom?
