Just before W.W.I.I., a young, soviet physicist makes an astounding leap of intuition that will revolutionize physics and the whole concept of space travel. Einstein's Relativity, by it's limits to speeds in space, locks man into the confines of our small solar system . . . until we become extinct. Population . . . at four times each century, will reach 24 billion by 2100 and 100 billion by 2200. By then Earth will be a dying planet and the four horsemen of the apocalypse will be riding hard. They are already riding. The only way to survive is to develop a true space-faring capability. This will only happen if someone can control the lives of hundreds of millions of people . . . and is willing to waste every one of them to develop and gain control of this technology. Einstein must be wrong or we are all dead. This technology will not only give us true space, but will supersede H-bombs and A-bombs, and it's almost ready. This is cold, hard fact. What will save us can also kill us. And a mad dictator is ready to do both. Two men may pay the ultimate price. But it's the only hope for mankind.
