Gravitational waves are ripples in the fabric of spacetime caused by some of the most violent and energetic processes in the Universe. Albert Einstein first predicted their existence in 1916 based on his theory of general relativity, which describes gravity as the curvature of spacetime caused by mass. Gravitational waves are generated by specific types of movement between massive objects, such as the spiraling and merging of neutron stars or black holes. These waves travel at the speed of light and carry information about their origins, as well as about the nature of gravity itself.
Recent research indicates that simple forms of matter from the early universe might be detectable through gravitational waves, which could also explain the nature of…
