Imperial Earth (1975) is a saga about the colonization of the solar system. The thematic determinants of the novel are determined by extrapolations of scientific hypotheses related to interplanetary travel, and by the SETI program.
Richard Firestone, Allen West, Simon Warwick-Smith
The book is the most readable and complete overview of the evidence that human civilization has already been nearly wiped out of the universe once – and that such cycles may repeat themselves every few tens of thousands of years.
