American astrophysicists who announced just months ago what they deemed a breakthrough in confirming how the universe was born now admit they may have got it wrong. The team said it had identified gravitational waves that apparently rippled through space right after the Big Bang. If proven to be correctly identified, these waves—predicted in Albert Einstein’s theory of relativity—would confirm the rapid and violent growth spurt of the universe in the first fraction of a second marking its existence, 13.8 billion years ago. The apparent first direct evidence of such so-called cosmic inflation—a theory that the universe expanded by 100 trillion trillion times in barely the blink of an eye—was announced in March by experts at the Harvard-Smithsonian Center for Astrophysics. The detection was made with the help of a telescope called BICEP2, stationed at the South Pole. After weeks in which they avoided the media, the team published its work Thursdayin the US journal Physical Review Letters. Read more at: Phys.org

Objavljeno spektakularno otkriće o širenju svemira Dokazi su pronađeni pomoću teleskopa BICEP na Južnom polu, u pozadinskoj radijaciji kozmičkih mikrovalova koji se šire svemirom još i danas Znanstvenici iz Harvard-Smithsoniana po prvi puta u povijesti otkrili su izravne dokaze o širenju svemira koje se dogodilo samo djelić sekunde nakon Velikog praska prije 13,8 milijardi godina. Dokazi su pronađeni pomoću teleskopa BICEP na Južnom polu, u pozadinskoj radijaciji kozmičkih mikrovalova koji se šire svemirom još i danas. Otisak koji su ostavili u vrijeme nastanka svemira pružit će uvid u to kakav je bio netom nakon Velikog praska. "Ovo je bilo nalik traženju igle u plastu sijena, ali umjesto toga pronašli smo željeznu polugu", rekao je vođa znanstvenog tima Clem Pryke.
