Einstein’s Prediction Comes True After 100 Years


Scientists have for the first time ever observed the phenomenon called as gravitation waves. These are ripples or disturbances caused in the fabric of space time, which reach our planet as a result of a cataclysmic event in some distant part of our universe. This rare phenomenon has further confirmed the General Theory of Relativity, put forth by Albert Einstein in 1915. This has further opened a new avenue of exploration into our cosmos.

The unique feature of these gravitational waves is that they carry information on their origins and the very nature of gravitational forces of the place where they originated from. Physicists claim that the current gravitational waves that were observed, originated during the final second of the union of two black holes. This led to the formation of one huge fast spinning black hole. The theory that two black holes can collide has been in existence for a long time. But this is the first time that scientists are able to observe this rare phenomenon.

The gravitational waves were observed on 14th September 2015, at 9.51 UTC by the twin Laser Interferometers located at Hanford, Washington and Livingston, Louisiana. Based on the signals that were observed, scientists at LIGO predict that the black holes that generated these gravitational waves would have mass more that 29 and 36 times of the sun, respectively. The event must have occurred around 1.3 billions of years ago. The gravitational waves had mass nearly thrice that of the sun. They also claim that the source of this rare event must have been situated in the Southern Hemisphere.

The presence of gravitational waves was first studies by Joseph Taylor Jr. and his team in the 1970s and 1980s. Scientists are hoping that this first observation of gravitational waves will increase the funding and construction of a global network of detectors that can then pool in their resources to observe further such rare events.
