Non-technical descriptions of cosmology, black holes, cosmic strings, inflation, quantum cosmology, and string theory.

This site contains the posts of a time taveler who was online between Nov 2000 and March 2001.

Profile of Albert Einstein, with additional teaching resources, Shockwave demonstrations, and animations of relativity concepts.

Research and discussion of time travel, quantum physicals and temporal displacement.

Gravity Probe B is the relativity gyroscope experiment being developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein`s general theory of relativity.

A peer-refereed, solely online physics journal publishing invited reviews covering all areas of relativity research. Published by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Potsdam, Germany.

Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull

An overview of black holes and information on current research from Cambridge

Simple explanation, black hole containment device, mathematics, energy equation, chaos and super string theories, power of the crystal, FAQ and links.

From the University of Illinois. Educational sequence suitable for high school students.

A brief history of the development of general relativity with hyperlinks to biographies of each contributor.

Presentation of new mathematical formulations for both the Special and General Theories of Relativity.

a multimedia introduction to the theory of relativity

A short overview of special relativity, filled with relativistic ray traced images. Explains relativistic effects using a theoretical spaceship.

The Laser Interferometer Gravitational-Wave Observatory (LIGO) project is a pioneering effort to design and construct a novel scientific facility - a gravitational-wave observatory - that will open a new observational window on the universe.

A complete online course in tensors and relativity

A brief overview of the theory of special relativity, and how it pertains to particles at SLAC (Stanford Linear Accelerator)

Special relativity, understanding, space phenomena, black holes, wormholes, cosmic strings and problems.

A modular manageable high-performance 3D tool for Numerical Relativity.

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.
