Most physicists believed that they were a peculiar feature of the highly symmetric solution found by Schwarzschild, and that objects collapsing in nature would not form black holes.
The simplest type of black holes is the known as Schwarzschild black holes, named after the scientist who discovered this solution of General Relativity.
最简单的一种黑洞叫做希瓦兹凯尔德黑洞，以一个发现了广义相对论解答的科学家的名字命名。

A few months later, Karl Schwarzschild gave the solution for the gravitational field of a point mass, showing that something we now call a black hole could theoretically exist.
