Black Holes
Beginning of paper
Black Hole, a theoretical concept in the study of gravitation. The
gravitational field of a black hole, which is an extremely dense body, is
so strong that, if the body is large enough, nothing, including
electromagnetic radiation, can escape from its vicinity. The body is
surrounded by a spheric ....

principle, energy can be emitted from the ergosphere.
According to general relativity, gravitation severely modifies
space and time near a black hole. As the horizon is approached from
outside, time slows down relative to that of distant observers, stopping
completely on the horizon. Once a body has contracted within its
Schwarzschild radius, it would theoretically collapse to a singularity—that
is, a dimensionless object of infinite density.
