For the entertainment of Darnell and others who dream about Space, here is technology that no human has seen. This slide was shown to a room full of physicists and not one figured out what it is. Like Kea's drawings, it may be too simple to understand. This could be the natural development of your planet, many decades from today.
Radial lines rise from the oceans, located over the centres of population and industry. Alpha is at longitude 100 West, over the Americas. Beta is at 140 East to serve Japan, Australia and East Asia. Gamma is at 80 East near the Indian subcontinent. Delta is at 20 East over Africa and Europe. By an amazing coincidence, the configuration resembles a peace symbol with Earth at its centre. Let us hope that it inspires humans to peaceful cooperation.
In the climax of Arthur Clarke's FOUNTAINS OF PARADISE, the dying hero envisions multiple Space Elevators connected by giant bridges 36,000 km over the Earth. That would securely brace the system against oscillations, making stability problems disappear. Once the radial lines are in place, connecting them with a Ring is a comparatively simple project. If Saturn and other gas giants can be decorated with Rings, why not Earth? The Ringworld can serve as an anchorage for giant rotating Space habitats. There is room for billions of people, with easy access to the resources of Space.
The nodes are also the best locations for singularity power. Power stations could beam energy to their respective regions of Earth. If Black Hole energy is not developed, this vision could alternately be powered by the Sun. The Ringworld could be dotted with solar power stations, an indirect way of tapping Black Hole energy. As seen in our redwood forest, life tends to seek the Sun as it grows skyward.
In the forest, the growth of trees builds an entire ecosystem. The redwoods create a habitat for creatures from insects to birds. Here the driving force is humanity, the only species capable of reaching Space. Like the redwoods, humans bring other life forms with them--plants, crops, fish, pets and nearly every other creature grown on Earth. The planet itself could someday return to a natural state. Earth would be Central Park and museum in the midst of a city.
We began the week in a redwood cathedral, observing how life naturally grows toward the sky. Nearly all humans dream about flying. The desire to reach Space may be as old as life on Earth. That life began deep underground, eventually moving to the oceans, to the land, and into the sky. Now a species has developed the ability to leave the planet completely. This simple picture shows a future in which all humans, along with other forms of Earth life, can someday reach the stars.
