ESA Cast Doubts on the Discovery of Gravitational Waves

February 7, 2015 By Carol Harper

Gravitational waves: Bicep2 at the South Pole

In March 2014, a group of astronomers claimed that they had found gravitational waves from the early universe. The discovery marked a new history in the arena of science. The finding is commonly known as BICEP2.

Recently, The European Space Agency completely rebuffs the idea of BICEP2. The intergovernmental organization informs that scientists considered dust particles of Milky Way as the gravitational waves.

Marc Kamiokowski, a cosmologist at Johns Hopkins University said that scientists no longer believe that BICEP2 spotted gravitational waves.

Scientists of Planck satellite worked together with the experts of BICEP2.  They compare the data of BICEP2 telescope with the Planck satellite in order to determine the accuracy of gravitational waves.  The BICEP2 data was recorded at a frequency of 150 gigahertz. In comparison, the Planck’s data was observed at 353 GHz.  The two telescopes studied the same region of the Milky Way.

In the end, the close analysis of the data shows that polarization of Cosmic Background Radiation is dust of Milky Way. Earlier, scientists interpreted these dust particles as the gravitational waves.

Jean Loup Puget, a Planck scientist at the Institut d’Astrophysique Spatiale discussed the outcome of the research in detail. He informs that joint effort of the two teams reveals that primordial B modes are only the galactic dust.

ESA Admits: The Gravitational Waves of BICEP2 was Space Dust

In 2014, scientists claimed that they discovered strong evidence regarding primordial gravitational waves. As per the study, the universe experienced rapid growth after a few seconds of Big Bang.  Astronomers dubbed the phenomena as BICEP2.

Recently, European Space Agency (ESA) admitted that the theory of BICEP2 was a mistake. The intergovernmental organization accepted that mistake happened due to optical illusion.

The researchers of Planck satellite worked together with the team of BICEP 2. The close analysis reveals that research lacks evidence regarding the primordial gravitational waves.

Scientists utilized numerous powerful telescopes like BICEP2 and Planck in order to spot these waves. They are usually found in the background of cosmic microwave (CBM). Astronomers believe that these radiations were released nearly 14 million years ago.

The latest report of European Space Agency informs that the dust particles present in the space gives birth to these waves.  The dust of the solar system contains characteristics pretty similar to microwaves background. Hence, astronomers considered them as microwave waves.

As per the latest ESA report, The BICEP2 team believed that these signals are originated in primordial gravitational waves. They were unaware that there is another thing that can produce similar waves
