In 1915, Albert Einstein, the German physicist gave birth to the idea of a 'gravitational wave' in his general relativism theory. The idea was an evolutionary thought of that time and till now exists. The wave was not identified by scientists for decades. After a time Einstein started to lose hope. But after a century the door of uncertainities has opened. Researchers of LIGO-VIRGO stated that they identified gravitational wave from the clashes of 2 blackholes which are 30 times heavier than sun. They also stated that the discovery will open the door of mystery of the universe and black holes.
