The recent research of American scientists has claimed for the existence of gravitational waves . Which will help for the understanding of the universe. According to the Albert Einstein’s predicted General theory of relativity, “Gravitational waves are produced by moving masses, and like electromagnetic waves moving with the velocity of the light”. Gravitational waves predicted by Albert Einstein’s general theory of relativity have been detected directly at last.
Gravitational waves emitted by the merger of two black holes have been detected, setting the course for a new era of observational astrophysics. The waves, which can be described as oscillating distortions in the geometry of spacetime, were first predicted to exist by Einstein in 1916, but they have never been observed directly. Now, in an extraordinary paper, scientists report that they have detected the waves at the Laser Interferometer Gravitational-wave Observatory (LIGO). From an analysis of the signal, researchers from LIGO in the US, and their collaborators from the Virgo interferometer in Italy, infer that the gravitational waves were produced by the inspiral and merger of two black holes (Fig. 1st), each with a mass that is more than 25 times greater than that of our Sun. Their finding provides the first observational evidence that black hole binary systems can form and merge in the Universe. 
Violent events, such as the collision of two black holes, are thought to be able to create ripples in space-time known as gravitational waves. The Laser Interferometer Gravitational Wave Observatory (LIGO) is currently searching for the first signs of these tell-tale indicators.
In 2014, scientists announced that they had detected gravitational waves left over from the Big Bang using the Background Imaging of Cosmic Extragalactic Polarization (BICEP2) telescope in Antarctica. Such waves are thought to be embedded in the cosmic microwave background. However, further research revealed that their data was contaminated by dust in the line of sight.
