What did Karl Schwarzschild discover?
Karl Schwarzschild discovered the first exact solution to Einstein's field equations of general relativity, now known as the Schwarzschild metric. This solution describes the gravitational field outside a spherically symmetric non-rotating mass, such as a black hole.
WhAT feature is found with Kerr black holes but not schwarzschild black holes?

Did Albert Einstein figure out what black holes are?
No, Albert Einstein did not specifically discover black holes. His theory of general relativity laid the foundation for understanding the structure of spacetime, which contributed to our understanding of black holes when other scientists like Karl Schwarzschild and John Wheeler applied his principles to describe them.
What would be the Schwarzschild radii of black holes of 1 billion solar masses?
The Schwarzschild radius is directly proportional to the mass of the black hole. It is about 2.95 km for every solar mass.
Do black holes expand or collapse?
Black holes neither expand nor collapse in the conventional sense. Once a black hole forms, it remains the same size unless it gains mass by absorbing matter or energy. However, black holes can grow in size over time as they capture surrounding material.
