Astronomers have published a new catalog of gravitational-wave detections that nearly doubles the total number of confirmed signals from black hole mergers. These gravitational waves are ripples in spacetime produced when massive objects like black holes spiral together and collide. The expanded dataset represents a significant milestone in gravitational-wave astronomy, which only began detecting these signals in 2015.
Why it matters
The growing catalog of gravitational-wave events allows scientists to better understand black hole populations, test Einstein's theory of general relativity under extreme conditions, and study the evolution of massive stars. This accumulation of data is essential for using gravitational waves as a new tool to explore the universe's most violent and energetic phenomena.
Astronomers have released the newest list of gravitational-wave detections, almost doubling the number of known signals from colliding black holes.
