At a fraction of the cost and effort of defending the southern border of the United States, America and the rest of the world could invest in a very different large-scale infrastructure and materials science project and construct a space-elevator—a tethered counter-balance that’s anchored to the surface of the Earth by a cable and held aloft by centrifugal force above the boundary of geostationary orbit. Dispensing with the needs for conventional rockets to escape Earth’s gravity and in the absence of a teleportation device to save on production costs, a space-elevator would confer an enormous economic advantage to the first country to develop it and make space-faring a reality. As a planet, we ought to ask ourselves where our priorities and our aspirations lie.
