Abstract
Schwarzschild presented his exterior and interior solutions a hundred years ago. They describe spacetime outside and inside an incompressible, spherically symmetric body. I give a review of these solutions and how they have been interpreted physically. Einstein predicted the existence of gravitational waves as a consequence of the general theory of relativity in June 1916. I briefly follow his thoughts about gravitational waves in the periods from 1016 to 1918 and from 1936 to 1938. The LIGO-detection of gravitational waves is reviewed. Consequences of this detection as investigated in later preprints are also discussed
