On March 17 , researchers led by John Kovac of Harvard University announced that gravitational waves from the universe had been found by a telescope at the South Pole called BICEP2 , according to the researchers was found the "smoking gun" for the theory of inflation, this would suggest that the space would have had a more rapid expansion of the speed of light in the first moments after the birth of the universe. It is considering the hypothesis that the ripples in space-time ( gravitational waves ) could be gleaned from the ashes of an exploded star . It was already known that the dust of exploded stars could affect the readings of the receiver BICEP 2 , for this reason , the telescope was pointed in a suitable place and have been used mathematical models to assess the dust in that part of the sky to estimate its effect on the polarization. According to David Spergel of Princeton University , "It 's important to consider the possibility that the galactic signal ( due to the dust of stars) could explain all of the signal seen by BICEP " . " Given its importance , the team BICEP2 needs a more convincing case . " The team leader BICEP2 did not respond to requests for comment on the new research, but the upcoming Planck observations should help to resolve the issue.Sources: arxiv.org/abs/1404.1899
