The article discusses finding of primordial gravitational waves by the astronomers using the Background Imaging of Cosmic Extragalactic Polarization2 (BICEP2) telescope at the South Pole in March 2014, and mentions other reports of researchers who showed that those were not gravitational waves. According to physicist Raphael Flauger the astronomer underestimated the fraction of polarization caused by dust in the map and these waves are not gravitational waves.
