This volume offers a comprehensive overview of our understanding of gravity at both the experimental and the theoretical level. Critical reviews by experts cover topics ranging from astrophysics (anisotropies in the cosmic microwave background, gamma ray bursts, neutron stars and astroparticles), cosmology, the status of gravitational wave sources and detectors, verification of Newton''s law at short distances, the equivalence principle, gravito-magnetism, measurement theory, time machines and the foundations of Einstein''s theory, to string theory and loop quantum gravity.
