Einstein’s Gravitational waves using #LIGO observatory



In 1916, an amazing prediction was made by Albert Einstein, that gravitational waves exists and since then physicians were on constant hunt for gravitational waves, which ripples in the fabric of space and time. Finally, the hunt is over. Gravitational waves exist!

The Laser Interferometer Gravitational Wave Observatory (LIGO), researchers who detected these waves few months back declared it as false news, but now with final confirmation and detection of gravitational waves, they have come up with official announcement.



Gravitational waves were observed on September 14th, 2015, at 5:51 am ET by both of the LIGO detectors, located in Livingston, Louisiana, and Hanford, Washington. The source? A supermassive black hole collision that took place 1.3 billion years ago. When it occurred, about three times the mass of the sun was converted to energy in a fraction of a second.

The discovery has been accepted for publication in Physical Review Letters.

Gravitational waves are ripples in the universe caused by some of the most energetic cosmic events, from exploding stars to supermassive black hole mergers. As they propagate through space and time, gravitational waves cause tiny tremors in atoms that make up matter. While Einstein predicted them in his general theory of relativity in 1916, and their existence was indirectly demonstrated in the 1980s, it wasn’t until the LIGO detector in 2002 hunted for elusive spacetime ripples.
