Details the events surrounding Roy P. Kerr's discovery of the solution for Albert Einstein's Theory of Relativity in 1963, and discusses how his accomplishment has impacted the work of later scientists--including Kip Thorne and Stephen Hawking--in their efforts to better understand black holes.

Looks at what modern scientific research, some conducted with the help of space-based facilities such as the Hubble Space Telescope and the Chandra X-ray Observatory, have revealed about black holes and their role in the formation of the universe.

Looks at what scientists have learned about black holes, focusing on the black hole known as Sagittarius A believed to exist at the center of the Milky Way, and discusses the possibility of being able to observe, and thus prove the existence of black holes with the use of technology already in development.
