One example is black hole recoil. During the merger of binary black holes, the gravitational waves is emitted. And because of the asymmetry of gravitational radiation, the resultant black hole can gain a recoil velocity up to 4000km/s, which is enough to escape the host galaxy. This phenomenon indicated that gravitational waves can also carry momentum as well as energy.
How much energy was released by the massive merger, and what was the frequency and wavelength of the gravitational wave? First, we can estimate the energy released by calculating the energy equivalent of the missing mass after the merger. Before the merger, the total mass of both black holes was 36 + 29 solar masses, or approximately 65 solar masses. After the merger, a single black hole with a solar mass of 62 remained. What happened to the missing three solar masses? It was turned into the energy transported by the subsequent gravitational wave throughout the universe. Using Einstein’s famous equation E = mc2, where E is the energy equivalent of the missing mass and c is the speed of light, we can estimate the energy released as gravitational waves. E = mc2 = 3 × (1.989 × 1030kg)(2.99792 × 108m/sec.)2 ≈ 5.4 × 1047 kg m2/sec2 = 5.4 × 1047 joules
Gravitational Radiation is to gravity what light is to electromagnetism. It is produced when massive bodies accelerate. You can accelerate any body so as to produce such radiation, but due to the feeble strength of gravity, it is entirely undetectable except when produced by intense astrophysical sources such as supernovae, collisions of black holes, etc.
