Summary
According to Einstein, space-time is like a fabric stretched all over the universe. Gravity is the warping of this universal fabric by a massive object like that of a star. A planet orbits a star when it is caught in this warp space. This idea led Einstein to a prediction that when a massive object collides with another, it produces gravity waves in the fabric of space-time. Weber was the first researcher to have developed a method to detect these gravity waves. A device called interferometer can be used to measure the intensity of gravitational waves. A set of huge laboratories named as the Laser Interferometer Gravitational Wave Observatories or LIGO are working on this daunting task of measuring gravity waves.
