Gravity Waves
[edit]The energy released by the binary as it spiralled together and merged was immense, with the energy of 3.0+0.5
−0.5 c2 solar masses (5.3+0.9
−0.8×1047 joules or 5300+900
−800 foes) in total radiated as gravitational waves, reaching a peak emission rate of about 3.6+0.5
−0.4×1049 watts – a level greater than the combined power of all light radiated by all the stars in the observable universe.[1]
