SÃ¥, du har lÃ¤st Dawkins “The God Delusion” och Hitchens “God Is not Great” och du har bestÃ¤mt dig fÃ¶r att tro pÃ¥ att Gud inte existerar. Men, vad (vem?) var det dÃ¥ som skapade vÃ¤rldsalltet? Vad var det som startade processen som ledde fram till att jag kan sitta hÃ¤r framfÃ¶r min dator och stÃ¤lla frÃ¥gan om vad som startade processen som ledde fram till att… ja, ni fattar.
Jo, vÃ¥rt universum kan ha skapat sig sjÃ¤lv:
However, the possible existence of closed timelike curves under certain extreme conditions may offer a solution to the problem of what came before the Big Bang, which most cosmologists believe started our universe.
In a paper submitted for publication, Li and Gott explore the question of whether anything in the laws of physics would prevent the universe from creating itself. “The universe wasn’t made out of nothing,” Gott suggests. “It arose out of something, and that something was itself. To do that, the trick you need is time travel.”
Li and Gott speculate that a universe undergoing the rapid early expansion known as inflation could give rise to baby universes, one of which (by means of a closed timelike curve) would turn out to be the original universe.
As they did for Misner space, the two physicists found a self-consistent vacuum state, demonstrating that closed time loops can occur under inflationary conditions in certain space-times. Hence, the researchers say, “the laws of physics may allow the universe to be its own mother.”
Hm. “StÃ¤ngda tidsliknande kurvor”? Babyuniversum som Ã¤r skapade av sig sjÃ¤lv?
Tror jag behÃ¶ver lite mer kaffe.
