Scientists are constantly striving to understand the gravitational force and are making stunning discoveries. They have witnessed the space-time distortion affected by the crash of two black holes occurred a billion light-years ago. According to the international team, the initial finding of gravitational waves would help open a new horizon in astronomy. It is the result of decades of exploration that could ultimately present an opening on the Big Bang. The journal Physical Review Letter publishes today the study report of LIGO Collaboration.
The LIGO Collaboration has several labs across the world to activate lasers through long tunnels for sensing waves on the basics of space-time. Gravitational waves mean victory for ultimate science. Anticipated signals are particularly delicate, which agitate the machine or interferometers with just a tiny proportion of the width of an atom. The back hole fusion was noticed by two widely separated LIGO centers in US.
The fusion emitted three times the mass of the Sun in untainted gravitational energy. Prof David Reitze, executive director, LIGO project disclosed in a press conference to journalists in Washington DC that they had already detected gravitational waves. He further added that it was the first occasion that the Universe conversed with them through gravitational waves, until then they were deaf.
Prof Karsten Danzmann, the European leader on the collaboration and from the Max Plank Institute for Gravitational Physics, Leibniz University, Hannover, Germany said that it was the first incident of direct discovery of gravitational waves, of black holes and a confirmation of General Relativity as the property of black holes, which are in unison what Einstein predicted nearly 100 years in advance.
