Profiting on Asteroids

Some of the first questions which come up in any practical discussion of space colonization are questions of economics. Suppose we go out and settle on a convenient asteroid with our little spaceship, what do we do when we get there? How do we make a living? What can we expect to export in order to pay for necessary imports? If space colonization makes any sense at all, these questions must have sensible answers. Unfortunately, we cannot hope to answer questions of economics until the asteroi...

 Nature Doesn't Need Our Help to Destroy the Earth

It had in the past sent glaciers down from the North Pole to grind up major portions of Asia, Europe, a...

 The Success of Zoos
