Abstract
Black holes are now real physical objects with a mass, length, and lifetime. They are at the very frontier of modern cosmology. The discovery of black holes took a hundred years of theoretical investigations until gravitational waves were found. We explore the long journey in this scientific drama and recall the inspiring thought of Descartes: There is nothing so far removed from us as to be beyond our reach, or so hidden that we cannot discover it.
