Sketch of a black hole showing the two parts: the
central Singularity that contains all the mass; and the surrounding
Event Horizon that is the boundary between our universe and oblivion.
real black hole in Cygnus A lies within the white dot in the center,
which is the accretion disk. Two jets emanate from its north and south
magnetic poles and span 3,000,000,000,000,000,000 miles.

The black hole is surrounded by an accretion disk and has jets shooting
out along its magnetic poles.
Sir Roger Penrose's plan to extract
unlimited clean energy from a
rotating black hole. An orbiting society sends a rocket that loops
around the black hole and dumps their trash at the event horizon. The
rocket returns with more kinetic energy than it began with, which is
easily converted to useful work energy.
