Detection of gravitational waves , Einstein’s relativity theory proofed to be concrete     

Albert Einstein predicted the actuality of gravitational wave as part of his relativity theory in 1930’s. This Thursday, after continuing a rigorous hunt for more than a century, physicists finally proved the existence of gravitational wave. The announcement of the detection of gravitational wave has shaken the world of astronomers. Astrophysicist Szabolcs Marka from Columbia University said “Until this moment, we had our eyes on the sky and we couldn’t hear the music, the skies will never be the same.”

A team of dedicated astrophysicists instilled an upgraded $1.1-billion instrument known as the Laser Interferometer Gravitational-Wave Observatory. LIGO was in charge of measuring gravitational wave from the far distant crash of two black holes. Physicists also commented that this new invention of detecting gravitational wave is of as deeper magnitude as of the invention of subatomic Higgs boson in 2012.

The theory of general relativity was few mere equations on paper. The concept of gravitational wave also a part of these equations .Because there weren’t any concrete experimental proof, theory of relativity was extremely controversial for many years. This ongoing skepticism regarding the theory of relativity lasted for a century. Many times several group of scientists approached a series of tests on general relativity. The idea of gravitational wave was so ground breaking that even Albert Einstein had doubts twice and declared that probably gravitational wave didn’t existed. According to scientist, detecting gravitational wave will aid us in exploring the most enormous distant corners of universe. Understanding black hole and relating with the profoundness of supernova and unraveling structure of neutron stars will be far easier. The finding of gravitational waves equates our first steps into investigating the universe through the gravitational-wave spectrum.

The gravitational waves were detected in the process of merging of two black holes. These black holes had enormous mass, one had the mass of 29 suns and the other one had the equivalent of 36 suns. Each of these black holes was approximately 50 kilometers in diameter. The LIGO judged the gravitational waves to be 1.3 billion years old. LIGO estimated that these two black holes collided at half speed of light.
