Before black holes

Abstract

Black holes are arguably the most counter-intuitive consequence of general relativity. They are super dense objects surrounded by unidirectional membranes, each hiding a singularity inside. A black hole traps everything that enters it, including light. The history of the discovery of those enigmatic objects starts in 1916, with the first solution to Einstein’s Equations for the gravitational field of a massive spherical-symmetric dimensionless body. But the publication that introduced them appeared only in 1939. This paper presents the historical events of the initial phase of research that led to the rise of the black holes as a concept. It presents a social, philosophical, and political analysis of the subject.
