Testing General Relativity with Gravitational Waves from Black Hole Merger

Gravitational waves detected from a black hole merger event, known as GW190521, suggest that the resulting black hole is larger than previously estimated. The waves indicate that the black hole settled into a stable, spherical shape and has a mass of around 250 times that of the sun, rather than the initially predicted 142 solar masses. These findings could provide valuable insights for testing Albert Einstein's theory of general relativity and further our understanding of gravitational waves and black holes.
