Unveiling the Enigmatic Symphony of the Universe: Mysterious Ripples, Gravitational Waves, and the Humming of Ancient Black Holes

Astronomers have detected a constant hum of gravitational waves throughout the universe, possibly caused by pairs of supermassive black holes merging together. Using 67 pulsars, the NANOGrav research team discovered these gravitational waves, which fluctuate and may take years or decades to oscillate. The waves confirm Einstein's predictions and provide insights into the evolution of massive objects in the universe.
