PDF-Observation of Gravitational Waves from a Binary Black Hole Merger

In 1916 the year after the final formulation of the field equations of general relativity Albert Einstein predicted the existence of gravitational waves He found that the linearized weakfield equations had wave solutions transverse waves of spatial strain that travel at the speed of light generated by time variations of the mass quadrupole moment of the source 12 Einstein understood that gravitationalwave amplitudes would be remarkably small moreover until the Chapel Hill conference in 1957 there was significant debate about the physical reality of gravitational waves 3.
