Hunt for Gravitational wave. Article by: Rahul Kumar According to Einstein, we should expect to find this radiation everywhere in space. So, why is it still one of astronomy’s most elusive targets? Gravity alters the shape of space and time. Paths of light and massive bodies curve under its influence. When something Agitate space-time with enough energy – say a supernova explosion – the distortion spreads out in ripples, like a stone when dropped in a pond. Those ripples or waves are called gravitational waves. But this waves are very weak and only if the accelerating object has enough mass, it should be possible to spot them. At least, that’s what we suspect. we’ve been trying to detect them ever since. In Einstein's theory of general relativity published in the year 1916 , gravity is treated as a phenomenon resulting from the curvature of spacetime . This curvature is caused by the presence of mass . Gene...
