#GWGreatestHits It took us a hundred years to detect gravitational waves, predicted by Albert Einstein in 1915 in his General Theory of Relativity (GR). This theory redefined the concept of gravity not as a force like Isaac Newton had described it, but rather as the bending of space-time surrounding massive cosmic objects. But is GR the ultimate theory of gravity, or can there be undiscovered physics beyond it? According to GR, gravitational waves are ripples in this space-time, produced during quakes or collisions of massive objects such as black hole and neutron stars. So detection of gravitational waves can help us to answer this intriguing puzzle.
