“Gravitational waves are distortions or ‘ripples’ in the fabric of space-time caused by some of the most violent and energetic processes in the Universe”. Albert Einstein was the first person who predicted the existence of gravitational waves. In his general theory of relativity. Einstein mathematically predicted that massive accelerating objects such as neutron stars or black holes circle each other and collide to create gravitational waves which disrupts space-time in such a way that waves of distorted space would radiate from the source. Also it is said that the gravitational waves would travel at the speed of light through the Universe. These waves carry with them information about their origins, as well as invaluable clues to the nature of gravity itself.
Although the presence of gravitational waves was predicted in 1916 there was no concrete evidence or proof of their existence. As the ripples of water, the ripples of the waves gets smaller as they move away. This makes them extremely hard to detect. In September 14 2015, LIGO Laser Inferometer Gravitational Wave Observatory heard a ripple. The event that created this ripple is estimated to have happened 1.3 bn years ago by collision of two black holes of 30 times the mass of our sun, moving at half the speed of light at the colliding movement. This collision created gravitational waves through the universe the speed of light. However the reverberations that LIGO sensed were tiny about 1/1000 diameter of a proton. These ripples matched the supercomputer models of gravitational waves predicted using the “theory of relativity”. This discovery finally proves the Einstein’s theory of relativity.
The proof of existence of gravitational waves will stimulate space agencies to plan more space programs to study gravitational waves. The study of gravitational waves is believed to be instrumental in better understanding the black holes supernovas and other massive space events and possibly the fundamental laws of the universe.
