Scientists: Gravitational waves found

British physicist Stephen Hawking, who has theorized about black holes for decades, congratulated the scientists behind the first-ever detection of gravitational waves.

He said the discovery will have a profound impact on how we understand our universe. Based on the observed signals, scientists estimate the black holes that collided were about 29 and 36 times the mass of the sun. This means that when a mass moves through the universe, it creates what can be referred to as "ripples" through space-time, better known as gravitational waves.

Besides proving that Einstein had a solid idea, the findings promise to change how we study the universe. In 1974, the indirect detection of gravitational waves won scientists the Nobel Physics Prize. More than a billion years ago - LIGO estimates about 1.3 billion - the two collided at half the speed of light.

The work is relevant now in the context of the discovery and with more advanced detectors scheduled to come up in the next few years, a press note issued by IISER said. At the Indian Institute of Science Research and Education in Thiruvananthpuram, Ms Archana Pai and her team helped test the gravitational waves from the event and found that it was consistent with Einstein's theory of relativity.

There are two black holes that are 100 kilometers across.

Mirrors set up by LIGO to detect gravitational waves.

When two black holes a billion light years from Earth began spinning toward each other, energy radiated outward.

Hawking said the discovery is consistent with his predictions on black holes the celebrated physicist made back in the seventies.

The discovery of gravitational waves is like opening another of our senses, Marka told CNN's Rachel Crane: hearing the universe as well as seeing it. After long years of searching for experimental evidence, researchers at the LIGO Collaboration were finally able to confirm Einstein's claim after they have detected subtle disturbances from these gravitational waves with the use of interferometers. "The area of the final black hole is greater than the sum of the areas of the initial black holes as predicted by my black hole area theorem", he said, as reported by The Guardian.
