Scientists and astronomers gather information about the universe by analyzing cosmic waves, specifically electromagnetic and gravitational waves, which carry information about distant objects and events. Electromagnetic waves, including visible light, X-rays, and radio waves, have been used for centuries to observe the universe, while gravitational waves, generated by the collisions of massive objects like black holes, are a more recent source of information. | Space Advances
