Last year in March, scientists claimed that they have found a pattern in the sky that could have been the proof that the universe has been created after a Big Bang, billions of years ago. Unfortunately, they overturned the claim that made the tour of the world with the speed of light. The European Space Agency was responsible to set the truth straight and release all new information to the media.
Ripples, that are small gravitational waves, have been discovered last year by a BICEP team (Clem Pryke, team leader for the BICEP/Planck analysis, John M. Kovac of the Harvard-Smithsonian Center for Astrophysics; Chao-Lin Kuo of Stanford; and Jamie Bock of Caltech). The link between them and the birth of the Universe was immediately made and the Eureka! moment had to be known and spread. The significant breakthrough was soon in every scientist’s mouth.
At present, at almost one year apart, the Planck group and the BICEP (acronym for Background Imaging of Cosmic Extragalactic Polarization) group have focused on making new researches that confirm that there were no authentic of conclusive evidence about the existence of this kind of waves or inflation. Jan Tauber, ESA project science for Planck has talked to the press about the difficulty of all these researches.
“Searching for this unique record of the very early Universe is as difficult as it is exciting, since this subtle signal is hidden in the polarization of the CMB [Cosmic Microwave Background – the legacy of light emitted only 380,000 years after the Big Bang], which itself only represents only a feeble few per cent of the total light.”
The interesting fact that has been discovered is that the interstellar dust in our Galaxy, the Milky Way, has the capacity of creating the same kind of gravitational waves about which the scientists believed that are related to the Big Bang. For this matter to happen, the BICEP group has sent a couple of telescopes at the South Pole in order to find the swirl pattern. The microwaves have been observed and studied in nine frequencies, so the dust was clearly distinguished. As a result, the waves couldn’t have been created in the first trillionth of a trillionth of a trillionth of a second after the universe has been born about 13.8 billion years ago. However, their final statement sounded a bit abstract: “gravitational waves remain elusive.”
“We’re going to have to have better data to get a definitive answer.”
