| Sound does travel in space, evidenced by the B flat note emanating from a black hole discovered by scientists in the last couple weeks. |
| At some point after its formation, the black hole emits a flare of superheated gases, travelling at relativistic speeds. |
| Gas and dust funnel towards a black hole in an accretion disk, swirling around and into the void like water down a drain. |
| He hacked at a wall of vines, which fell and revealed a gaping, black hole. |
| But before this material is permanently captured, it gathers into a swirling accretion disk that surrounds the black hole and radiates intensely. |
| At those rates, each galaxy could easily have formed the quasar and its black hole power source in just a few hundred million years. |
