American theoretical physicist (1904–1967)
J. Robert Oppenheimer was an American theoretical physicist who served as the director of the Manhattan Project's Los Alamos Laboratory during World War II. He is often called the "father of the atomic bomb" for his role in overseeing the development of the first nuclear weapons.Source: Wikipedia (CC BY-SA)
Hartland Snyder
American physicist (1913–1962)
Hartland Sweet Snyder was an American physicist who, together with J. Robert Oppenheimer, showed how large stars would collapse to form black holes. This work modeled the gravitational collapse of a pressure-free homogeneous fluid sphere and found that it would be unable to…Source: Wikipedia (CC BY-SA)
Oppenheimer–Snyder model
Exact solution to the Einstein field equations
In general relativity, the Oppenheimer–Snyder model is a solution to the Einstein field equations based on the Schwarzschild metric describing the collapse of an object of extreme mass into a black hole. It is named after physicists J. Robert Oppenheimer and Hartland Snyder, who…Source: Wikipedia (CC BY-SA)
Black hole
Astrophysical phenomena
A black hole is a massive, compact astronomical object so dense that its gravity prevents anything from escaping, even light. Albert Einstein's theory of general relativity predicts that a sufficiently compact mass will form a black hole. The boundary of no escape is called the…Source: Wikipedia (CC BY-SA)
