Dyson Spheres

The mathematician Freeman Dyson, of the Institute for Advanced Study, offers a scheme in which the planet Jupiter is broken down piece by piece, transported to the distance of the Earth from the Sun, and reconstructed into a spherical shell – a swarm of individual fragments revolving about the Sun. The advantage of Dyson's proposal is that all of the sunlight now wasted by not falling upon an inhabited planet could then be gainfully employed; and a population greatly in excess of that which...

 Evidence of Global Warming in Just the Past 12 Months

Is the climate crisis real? Yes, of course it is. Pause for a moment to consider these events of just the past 12 months: • Heat. According to NASA, 2010 was tied with 2005 as the hottest year measured since instruments were first used systematically in the 1880s.
