- Gravitational waves are minute distortions or ripples in spacetime caused by the acceleration of massive objects.
- They are produced by cataclysmic events such as the merger of binary black holes, the coalescence of binary neutron stars, supernova explosions and processes including those of the early universe shortly after the Big Bang.
- Studying them offers a new way to observe the universe, providing valuable insights into the behavior of matter under extreme conditions.
