Cosmic breakthrough: Physicists detect gravitational waves while studying black-hole merger, latest update

Albert Einstein’s general theory of relativity has been proved right after more than a hundred years. The geometric theory of gravitation was published by one of the most famed scientists that the world has produced in the year 1915.

After decades of apprehensions about the theory being relevant and right, it has been proved right beyond any doubt that the theory that Einstein put forward was completely true. After years of research scientists have found what Albert Einstein predicted as part of the theory: gravitational waves.

While talking about the findings regarding gravitational force David Reitze, executive director of LIGO, the Laser Interferometer Gravitational-Wave Observatory says,”We have detected gravitational waves. We did it”. Reitze made the announcement Thursday at the National Press Club in Washington surrounded by other LIGO researchers and National Science Foundation head France Cordova.

Gravitational waves detectedFor the last more than two decades the LIGO has been working without pause on this project. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment to detect gravitational waves. Cofounded in 1992 by Kip Thorne and Ronald Drever of Caltech and Rainer Weiss of MIT, LIGO is a joint project between scientists at MIT, Caltech, and many other colleges and universities. LIGO is funded by the National Science Foundation (NSF)

The LIGO director said that the gravitational waves — ripples in space-time — were created by the merging of two black holes. One black hole had the mass of 29 suns; the other was the equivalent of 36 suns. Each was perhaps 50 kilometers (30 miles) in diameter. More than a billion years ago — LIGO estimates about 1.3 billion — the two collided at half the speed of light. Gravitational waves pass through everything, so the result traveled through the universe for that time before reaching Earth.

While talking about the findings of his scientists Reitze said that the gravitational waves stretched and compressed space around Earth “like Jell-O. However, the waves are so small that it takes a detector like LIGO, capable of measuring distortions one-thousandth the size of a proton, to observe them. They were observed on September 14, 2015. Without doubt this is a ground breaking finding.
