A mysterious anomaly enters the solar system and prevents solar energy from reaching the earth. Human civilization retreats underground to be powered by tiny solar reactions inside tiny universes of compressed space until things return to normal. A scientist discovers that gravity has also been blocked and the sun is now out of reach. His further explorations discover that a long vanished advanced reptilian civilization had followed a similar path when a similar anomaly led to the extinction of the dinosaurs, and their superior technology can be adapted to save mankind.
