Longer gravitational waves from colliding black holes could help explain why galaxies grow and change.
In a historic first, astronomers have detected low-frequency gravitational waves using a galaxy-sized antenna of millisecond pulsars in the Milky Way.
The breakthrough was hailed as a major milestone that opens a new window into the universe.
Scientists from multiple countries, including the United States, India, Australia, and China, have made a groundbreaking discovery regarding gravitational waves. They have confirmed the existence of a cosmic 'background hum,' a long-theorised form of gravitational waves that permeate the universe.
