The Hunt For Vulcan by Steven Levenson

And How Albert Einstein Destroyed a Planet and Deciphered the Universe

A concise historical narrative tracing the 19th-century effort to explain Mercury’s anomalous orbit by proposing a hidden planet inside its path, following predictions, reported sightings, and exhaustive searches that captivated astronomers for decades. The story culminates in the advent of general relativity, which resolves the mystery and renders the supposed planet unnecessary. Along the way, it illustrates how scientific progress is shaped by bold hypotheses, persistent error, and paradigm-shifting insights.
