An enigmatic prediction of Einstein’s general theory of relativity are gravitational waves. With the observed decay in the orbit of the Hulse-Taylor binary pulsar agreeing within a fraction of a percent with the theoretically computed decay from Einstein’s theory the existence of gravitational waves was firmly established. Currently there is a worldwide effort to detect gravitational waves with...
