Human beings live in the solar system, a small corner of the Milky way, and have lived on the third planet revolving around the sun for more than 100,000 years. Humans established more than 200 different administrative regions (they called them "states") on this small planet (they called it "Earth") until the first thinking robot was born on Earth. With the help of robots, humans quickly mastered the technology to transform other planets and started a magnificent interstellar colonial movement. Human beings multiplied and expanded in the Milky way like locusts, boarded one desolate planet after another with their indelible ignorance and wisdom, greed and conscience, and involved the Milky way in the long interstellar warring States era, until the entire Milky way was unified. the rise of a huge empire that rules more than 25 million inhabited planets, spans 100, 000 light-years and counts trillions of people. A delicate turning point took place in 12020 after the founding of the Galactic Empire. Harry Shelton, a young mathematician who has just turned 32, pioneered Psychological History, a discipline that can accurately deduce the future of all mankind with mathematical formulas-"prophecy" has since become a trusted science.
