European physicists confirm primordial cosmic gravitational waves found error

According to the Nature report, the group of physicists from the European Space Agency’s Planck satellite announced by the investigation and found that the big bang gravitational waves very early indeed a mistake, an official report will be published next week. Scientists believe that the cosmic microwave background investigation BICEP2 telescope discovered B-mode polarization is not caused by cosmic primordial gravitational waves, but the Milky Way interstellar dust interference. Cosmic microwave background radiation information is old big bang era legacy, dating back up to 14 billion years.

After the very early universe, gravitational wave signal was found in the Antarctic BICEP2 telescope, the European Space Agency Planck satellite involved in the investigation, the European Space Telescope, scientists use this data found that the so-called gravitational waves original evidence is not sufficient, in order to further demonstrate this found Keck joined the identifications. While we deny the findings about the gravitational wave signals, but this result was not so surprised scientists in the field, before many scientists suspect that this conclusion is correct.

March 2014, BICEP2 telescope observations show in the Big Bang emerged during the gravitational wave signals, scientists in the investigation of cosmic microwave background radiation detection to B-mode polarization within the next for nearly a year, scientists have been determined The discovery is to be reliable. Scientists originally thought, we found very early after it was confirmed that some of the gravitational wave signal hypothesis about the origin of the universe, and reveal the mechanism of the universe after the Big Bang the accelerating expansion of space-time. However, the interstellar dust in the Milky Way memory for observing the formation of interference, and produces the wrong conclusions.

To demonstrate the effect of galactic dust interference, scientists use the Planck Space Telescope survey of background radiation, which can analyze the impact of dust generated BICEP2 project scientist John Kovacs from Harvard University, he is the first author of the study paper He thought when we first discovered this signal still use background radiation model based Galaxy dust, dust emission values ​​actually true day we observe the region are much lower, so unfortunately we have not been able to find cosmic expansion mark.
