Last March, the media echoed a far-reaching scientific news : the team at the BICEP2 telescope (Background Imaging of Cosmic Extragalactic Polarization 2) had detected wrinkles in the sky that were probably tiny gravitational waves. distortions in the echo of the big bang.
This would confirm the theory of cosmic inflation, according to which the universe experienced enormous growth shortly after birth, an explosive process that lasted less than a second.
Now, a study published by researchers from the European Space Agency (ESA) Planck mission in the journal Astronomy and Astrophysics indicates that the region of the sky analyzed by BICEP2 had more galactic dust than scientists had calculated, which he was able to blur his observations.
This calls into question the finding , already discussed by other colleagues since it was announced. We will have to wait until the end of the year to know the final result of the joint work currently being carried out by the astrophysicists of the Planck Mission and BICEP2.
