The first indirect evidence for the existence of gravitational waves came in 1974 from the observed orbital decay of the Hulse–Taylor binary pulsar, which matched the decay predicted by general relativity as energy is lost to gravitational radiation.
Evidence of gravitational waves was first deduced in 1974 through the motion of the double neutron star system PSR B1913+16, in which one of the stars is a pulsar that emits electro-magnetic pulses at radio frequencies at precise, regular intervals as it rotates.
Einstein in 1916 proposed the existence of gravitational waves as an outgrowth of his ground-breaking general theory of relativity, which depicted gravity as a distortion of space and time ...

Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are permeating the universe at low ...
Scientists have observed for the first time the faint ripples caused by the motion of black holes that are gently stretching and squeezing everything in the universe. “It’s really the first ...
Each further limited the gravitational wave background and, in the second case, techniques to precisely determine the barycenter of the solar system were refined. In 2020, the collaboration presented the first evidence of gravitational wave background within the 12.5-year data release, taking the shape of a noise consistent with the ...
The blue lines are gravitational waves, ripples in time and space, which is how astronomers detected the merger, and orange and red areas indicate parts of the neutron star being stripped away.
