"Men are weak now, and yet they transform the Earth?s surface. In millions of years their might will increase to the extent that they will change the surface of the Earth, its oceans, the atmosphere and themselves. They will control the climate and the solar system just as they control the Earth. They will travel beyond the limits of our planetary system; they will reach other Suns and use their fresh energy instead of the energy of their dying luminary."
