Ground breaking discovery claimed as LIGO detects gravitational waves

  • Scientists at the Laser Interferometer Gravitational Wave Observatory (LIGO) in the U.S have detected signals of gravitational waves emanating from two merging black holes which are 1.3 billion light years away, arriving at the instrument on Earth. The ripples were being searched for a decade now in space time which was predicted by Albert Einstein 100 years ago precisely. These gravitational waves are ripples in space time which dash across the entire universe with the speed of light. The LIGO experiment has a four kilometer long tunnel and uses laser to measure the changes in the distance between the ends. As GW enters the tunnel it stretches space and direction while dispersing space in another direction. The announcement was beamed across all the laboratories of the world which participate in the LIGO Science Collaboration (LSC) which comprises 1000 scientists from 16 countries.
