[[Physics|Physicists]] describe these waves as being produced in the final fraction of a second of a collision of two [[black hole]]s merging into a single, more massive, spinning black hole. A portion of their mass is converted into the energy carried by a strong burst of gravitational waves, as given by E=mc². <br/i>
