Scientists Detect Gravitational Waves from Black Hole Mergers

Scientists have discovered gravitational waves that provide evidence supermassive black holes exist in merging galaxies.
The gravitational waves were detected using radio telescopes to monitor pulsars, which helped determine the slight changes in distance caused by the gravitational waves.
The discovery confirms predictions made in Einstein's theory of general relativity that gravitational waves exist and are emitted when massive objects like black holes move and collide.
The gravitational waves are primarily low frequency, created by supermassive black holes orbiting and merging at the centers of galaxies.
Studying these gravitational waves could reveal insights into the evolution of galaxies and the formation of black holes in the early universe.
