Black Holes Made Simple Einstein developed the general theory of relativity, Karl Schwarzschild found a solution for the equations of general relativity in empty space. He started by assuming only that the solution was SPHERICALLY SYMMETRIC. This means that no matter how the system...A site explaining the Schwarzschild solution and how it leads to black holes.

black holes and event horizons ghosts of stars Formed when a massive star collapses from its own gravity, a black hole has such a strong pull of gravity that not even light or other stars can escape from it.

This presentation also addresses the questions: "Can we see inside a black hole?" and "Can a falling observer cross the singularity without being crushed?"

We review the observational evidence for black holes, and briefly discuss some of their properties. We also describe some recent developments involving cosmic censorship and the statistical origin of black hole entropy

It has been recently pointed out that black holes of constant curvature with a "chronological singularity" can be constructed in any spacetime dimension. In this paper, a brief summary of these new black holes is given.

Non-perturbative quantum general relativity provides a possible framework to analyze issues related to black hole thermodynamics from a fundamental perspective.

The aim of these notes is both to review the standard understanding of the Hawking effect. The fundamentals of the Unruh effect are reviewed, and then the Hawking effect is explained as a ``gravitational Unruh effect".

This article presents in a pictorial way the basic concepts of black hole's theory, as well as a description of the astronomical sites where black holes are suspected to lie.

This article gives an elementary review of gravitational collapse and the cosmic censorship hypothesis. Known models of collapse resulting in the formation of black holes and naked singularities are summarized.
