" "Starting from Einstein's theory of general relativity, Oppenheimer and Snyder found solutions... that described what happens to a massive star when it has exhausted its supplies of nuclear energy. The star collapses gravitationally and disappears from the visible universe, leaving behind only an intense gravitational field to mark its presence. The star remains in a state of permanent free fall, collapsing endlessly inward into the gravitational pit without ever reaching the bottom. ... In my opinion, the black hole is incomparably the most exciting and the most important consequence of general relativity. But Einstein ... was actively hostile to the idea of black holes. ... Oddly enough, Oppenheimer too in later life was uninterested in black holes, although... they were his most important contribution to science. ... Oppenheimer in his later years believed that the only problem worthy of attention of a serious theoretical physicist was the discovery of fundamental equations of physics. Einstein certainly felt the same way.

Black holes were invented by J. Robert Oppenheimer and Hartland Snyder in 1939. Starting from Einstein's theory of general relativity, Oppenheimer and Snyder found solutions of Einstein's equations that described what happens to a massive star when it has exhausted its supplies of nuclear energy. The star collapses gravitationally and disappears from the visible universe, leaving behind only an intense gravitational field to mark its presence. The star remains in a state of permanent free fall, collapsing endlessly inward into the gravitational pit without ever reaching the bottom. This solution of Einstein's equations was profoundly novel. It has had enormous impact on the later development of astrophysics.
Additional quotes by Freeman Dyson
Rutherford did not pretend to understand quantum mechanics, but he understood that the Gamow formula would give his accelerator a crucial advantage. Even particles accelerated at much lower energies ... would be able to penetrate into nuclei. Rutherford invited Gamow to Cambridge in January 1929 ... [They] became firm friends and Gamow's insight gave Rutherford the impetus to go full steam ahead with the building of his accelerator.
The progress of science requires the growth of understanding in both directions, downward from the whole to the parts and upward from the parts to the whole. A reductionist philosophy, arbitrarily proclaiming that the growth of understanding must go only in one direction, makes no scientific sense. Indeed, dogmatic philosophical beliefs of any kind have no place in science.
