Stephen Hawking may be wrong

Last week British theoretical physicist Stephen Hawking suggested that humans should colonize outer space to escape the problems we have helped create on Earth.

"It is important for the human species to spread out into space for the survival of the species," said Hawking at a news conference in Hong Kong. "Life on Earth is at the ever-increasing risk of being wiped out by a disaster, such as sudden global warming, nuclear war, a genetically engineered virus or other dangers we have not yet thought of."

While Hawking may be one of the most respected and preeminent scientists in the world, his comments taken at face value seem off base, since at worst, they suggest that instead of addressing problems here on Earth, we should start over on another planet, essentially discarding our planet like a used candy wrapper or soda can.

Hawking, who has long pushed for space exploration and has performed groundbreaking research on black holes and the origins of the universe, believes that we could have a permanent base on the moon in 20 years and a colony on Mars in the next 40 years. However, the cost of such an endeavor would surely extend in the trillion dollar range. Imagine what that money could do on this planet if applied to non-polluting energy technologies, human health, or biodiversity preservation.

There is no question that Hawking is concerned for the fate of humanity -- on Friday, in an online forum, Hawking asked, "In a world that is in chaos politically, socially and environmentally, how can the human race sustain another 100 years?" -- but is spending a fortune on space exploration necessarily the best solution at the present time?
