Answer:
When material falls under gravity, it releases energy. When dust and gas fall in the extremely strong gravity around a black hole, enourmous amounts of energy are liberated. ... While no energy can escape from beyond the event horizon around the black hole, energy is released from the material as it falls in and if two black holes collide in the vacuum of space, do they make a sound? Sound waves can't travel in the almost perfect vacuum of space – no one can hear you scream, as the tagline from Alien goes. But electromagnetic and gravitational waves can, and a new album has turned these signals from space into musical tracks.
