General Relativity Tutorial (John Baez) This is bunch of interconnected web pages that serve as an informal introduction to general relativity. The goal is to demystify general relativity and get across the key ideas without big complicated calculations.
Falling into a Black Hole (Andrew Hamilton) Fall into a black hole on a real free fall orbit. All distortions of images are real, both general relativistic from the gravitational bending of light, and special relativistic from the near light speed orbit.
Lecture Notes on General Relativity Download lecture notes on special relativity, general relativity, differential geometry, and spherically symmetric space-times in postscript format.

Cosmology This page contains information about the course Cosmology and exobiology read in the fall semester 1999 at the Physics Institute of NTNU, Trondheim
Tensor Calculus and Continuum Mechanics A free downloadable textbook on introductory tensor analysis and continuum mechanics, in PDF format, from Professor John J. Heinbockel at Old Dominion University.
General Relativity and Cosmology An online notes from the University of British Columbia featuring simple explanations of cosmological phenomena.
Theory of Relativity Website for an online relativity class. Covers special relativity in depth and general relativity at a more qualitative level. Contains tutorial material, references, and links.
Cambridge Relativity Non-technical descriptions of cosmology, black holes, cosmic strings, inflation, quantum cosmology, and string theory.
Spacetime 101 (Patricia Schwarz) some basic background covering how mathematical models of space and time have evolved since ancient times, from the Pythagorean Rule to Newtonian mechanics, Special Relativity and General Relativity.
Special Relativity A set of online lecture notes for a course in special relativity from the University of Winnepeg.
Modern Relativity A set of notes outlining general relativity and its applications, including modern theories of FTL travel and wormholes.
Black Holes A very thorough introduction, studies the Schwarzschild, Reissner-Nordstrom, and Kerr solutions using a variety of coordinate systems. Additional topics include gravitational collapse, horizons, singularities, Carter-Penrose diagrams (aka conformal compactification), Hawking radiation and black hole thermodynamics
