This expansive Web site features the Max Planck Institute for Gravitational Physics' research dealing primarily with geometric analysis and gravitation, astrophysical relativity, quantum gravity and unified theories, and laser interferometry and gravitational wave astronomy. After learning about the Institute's origins in 1995, researchers can find out about the institute's intense efforts and hardships in developing a consistent theory of quantum gravity as well as its investigation in gravitational radiation and causal structures. The site provides visitors with downloads to many published articles as well as links to two free access electronic review journals: _Living Reviews in Relativity_ and _Living Reviews in Solar Physics_. While some content is not in English, all visitors can find valuable information about research in gravitational physics.
