So this is a problem, believe it or not, that reflective physicists really think a lot about, and at this point they tend to go metaphysical, say, well, maybe the set of laws that describes our universe, it's just one set of laws and it describes one part of reality, but maybe every consistent set of laws describes another part of reality, and in fact all possible physical worlds really exist, they're all out there.
Tako da je to problem, vjerovali ili ne, o kojem teoretski fizičari  puno razmišljaju te su u ovom trenutku skloni metafizici, primjerice, možda je skup zakona koji opisuje naš svemir samo jedan skup zakona i opisuje jedan dio realnosti, ali možda svaki konzistentni skup zakona opisuje drugi dio realnosti, i možda ustvari svi mogući  fizički svjetovi zapravo postoje, svi su tamo negdje.
