If you have a free hour or ten, check out some of the learned, mind expanding answers to this year’s edge.org question, which is “What game-changing scientific ideas and developments do you expect to live to see?”
I am going to try and cover some of the more interesting responses over the next few days. I’ll start with John Gottman’s anticipation of earthlike colonies:
The technological changes were small at first. In 2007 a telescope was developed that could search for planets in the Milky Way within 100 light years of Earth. The next version of the telescope in 2008 did not have to block out the light of the new star to see the planets. It could directly see the reflected light of the planets closest to every star. That made it possible to do spectroscopic analysis of reflected light and search for blue planets like Earth. Within a decade, 100 Earth-like planets had been identified within 100 light years. In the next two centuries that number increased to 50,000 blue planets.
Within the next two centuries the seemingly impossible technical problems of space travel began to be solved. Problems of foil sails were solved. Designs emerged for ships that could get up to 85% of the speed of light within 2 years, using acceleration from starts and from harnessing the creative energy of empty space itself. The Moon, Europa and Mars were colonized. Terra-forming technologies developed. Many designs emerged for the spinning complete 2-mile Earth-habitat ship that produced a 1-g environment. Thousands of people wanted to make the trips.
