Gravitational Waves: 7 Interesting Facts

BENGALURU: “We have detected gravitational waves. We did it,” said David Reitze, Executive Director of the Laser Interferometer Gravitational-Wave Observatory (LIGO), at a press conference in Washington. After half a century of trial and error, and 25 years of perfecting a set of sensitive instruments to identify a distortion in space time, On February 11, a team of scientists announced that they had detected a phenomenon called gravitational waves for the first time. Some of the interesting facts of gravitational waves are as follows, reports ET.

Predicted by Einstein a Century Ago

Albert Einstein was the first person to predict gravitational waves in his general theory of relativity. The theory states that mass warps space and time, much like placing a bowling ball on a trampoline. Other objects on the surface will 'fall' towards centre—a metaphor for gravity in which the trampoline is space-time.
