Astronomers see a Hint of the Gravitational Wave Background to the Universe – Universe Today
Astronomers have found evidence of faint gravitational waves using an array of pulsars in our galaxy.
Gravitational-wave astronomy is still in its infancy. LIGO and other observatories have opened a new window on the universe, but their gravitational view of the cosmos is limited. To widen our view, we have the North American Nanohertz Observatory for Gravitational Waves (NANOGrav).
Gravitational waves are created by the motion of massive objects. Most of the gravitational waves we’ve detected come from the merger of black holes. In their last moments, binary black holes orbit each other very quickly,…
