Cordelia's Tour - Greg Egan

"The view from near, and inside, a black hole

Below are views at various distances from a black hole. These are wide-angle shots, each about 127° across (the same apparent width as a 4-metre object just 1 metre away). Distances are given in the “Schwarzschild r” coordinate — the circumference of a circle centred on the hole, divided by 2 π — and in units of “M”, which is a scale determined by the mass of the hole. For Chandrasekhar, a twelve solar-mass hole, M = 17.6 km. The event horizon lies at r = 2 M."
