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.
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.

In particular, it could provide evidence for inflation, from gravitational waves emitted either by the process of inflation itself (according to some theories) [38] [39] or at the end of inflation; [40] first-order phase transitions may also produce gravitational waves. [36]
If you were worried that the first confirmed detection of gravitational waves was just a one-off result... don't be. Researchers analyzing LIGO data have verified a second instance (recorded in ...
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 finally found the gravitational wave background, ushering in Astronomy 2.0. It's literally a whole new way to look at the universe.
This framework could be used to analyze binary systems observed by gravitational-wave observatories. [225] 1995 – Hubble Deep Field image taken. [226] It is a landmark in the study of cosmology. 1998 – The first complete Einstein ring, B1938+666, discovered using the Hubble Space Telescope and MERLIN. [227] [228]
