Einstein didn't come up with the idea of black holes. Laplace did; before General Relativity for that matter. Meanwhile, Laplace gets to speculate about such things without being considered a goofball because he invented big chunks of mathematics, optics and physics. In fact, nobody in the physics community spoke of black holes at all until the 1960s when they began converting agricultural colleges into warehouses for people who speculate on untestable things.
