Updated throughout with recent developments and additional illustrations

Reveals how solar outbursts caused the end of the last ice age, unleashed catastrophe upon ancient advanced civilizations, and led to six millennia of a Solar-Induced Dark Age

Includes evidence from solar science, geology, oceanic circulation patterns, the Sphinx, the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Gbekli Tepe complex in Turkey

In this newly revised and expanded edition, updated throughout with recent developments, geologist Robert Schoch builds upon his revolutionary theory that the origins of the Sphinx date back much further than 2500 BCE and examines scientific evidence of the catastrophe that destroyed early high culture nearly 12,000 years ago.

Combining evidence from multiple scientific disciplines, Schoch makes the case that the abrupt end of the last ice age, circa 9700 BCE, was due to an agitated Sun. Solar outbursts unleashed electrical/plasma discharges upon Earth, triggering dramatic climate change as well as increased earthquake and volcanic activity, fires, high radiation levels, and massive floods. Schoch explains how these events impacted the civilizations of the time, set humanity back thousands of years, and led to six millennia of a Solar-Induced Dark Age (SIDA). Applying the SIDA framework to ancient history, he explores how many megalithic monuments, petroglyphs, indigenous traditions, and legends fall logically into place, including the underground cities of Cappadocia, the Easter Island rongorongo glyphs, and the Gbekli Tepe complex in Turkey. He also reveals that our Sun is a much more unstable star than previously believed, suggesting that history could repeat itself with a solar outburst powerful enough to devastate modern society.

Weaving together a new view of the origins and antiquity of civilization and the dynamics of the planet we live on, Schoch maintains we must heed the megalithic warning of the past and collectively prepare for future events.
