Newt Gingrich’s moon colony may be crowded by trespassers soon after it is settled. Two Canadian teens(!), investing about $400 and under five months of work, recently launched a small Lego man 25 km (15.5 mi) above the earth, reaching the stratosphere.A hundred years ago, spaceflight was science fiction. Fifty-five years ago, the Soviet Union shocked the world with the launch of a small, bleeping sphere into space. And now? Some high school kids from our neighbor to the north gave a Lego man a ride into near space. Next stop: the moon.
Science has made vast leaps in progress; who would have thought even a decade ago that basement experiments would put legos in space or iPhones in the stratosphere
? Yet this is also something to be wary of. If Canadian teens can put Legoman into space, what will do generations of terrorists and rogue governments do?Weapons of mass destruction still cost a lot of money. But for how long? In fifty years what will high school students and terrorists be able to do that only well-funded and innovative scientists can do today?
