Supermassive: Black Holes at the Beginning and End of the Universe by James Trefil and Shobita Satyapal

"This book traverses the incredible history of black holes and introduces contemporary developments and theories on still unanswered questions about the enigmatic objects. From the early work of Albert Einstein and Karl Schwarzschild to an insider look at black hole-galaxy connection research, the comprehensive book surveys an exciting and evolving branch of space science, with topics that include: visibility of black holes; quasars, the brightest objects in the universe; the black hole at the center of the Milky Way; popular theories on the origin of black holes; cosmic X rays; death of supermassives; black hole collisions; black holes in science fiction. Invisible to the naked eye and telescopes, black holes have mystified and entranced astronomers, scientists, and humanity for more than a century. The first image of a supermassive black hole was only unveiled in 2019, and new black holes are continually discovered. Supermassive illuminates what we know about black holes so far and what we have yet to uncover." — Provided by publisher. Unrated. Commercial audiobook. 2025.
