With this radical discovery that went against the Church, they created our contemporary world. Heaven on Earth is an intimate examination of this scientific family.

In deep caves on frozen worlds. And we dream. Of green hills. Blue skies. Golden fields. We dream of Earth. And for the first time, we have hope.

Zetetic Astronomy is the magnum opus of Samuel Rowbotham (1816-1884), a self-taught polymath, debater, faith healer, and early advocate of Utopian socialism. Drawing from a wide variety of contemporary sources, Christian scripture, and his own investigative and experimental skills, Rowbotham advocated tirelessly for his thesis that the true shape of the Earth was a plane, refuting all suggestions of rotundity. His arguments continue to captivate, persuade, and entertain up to the present day.

Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.
