Gravitational Waves

Gravitational Waves are ripples in fabric of space-time.

Who Proposed Idea of Gravitational Waves

Idea was proposed by french Mathematician Henry Poincaré in 1905.
Albert Einstein explained behaviour of such a waves. General Theory of Relativity states energy can be transferred in the form of gravitational radiation.

When two heavy objects merges the gravitational waves are produced on the fabric of space-time as Einstein said.
It took years for scientists to accept the existence of gravity waves and gravitational waves can be detected.

Detection of Gravitational Waves

Finally in 2016 Laser Interferometer Gravitational-Wave Observatory(LIGO) detected Gravitational Waves. Which was produced by merging of two Blaack Holes. Detection made after 100 years of General Relativity.
