Do u know that mankind will need to venture far beyond planet Earth to ensure the long-term survival of our species, according to the world's best known scientist, Professor Stephen Hawking. http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/11/30/uhawking130.xml "The long-term survival of the human race is at risk as long as it is confined to a single planet," he said. "Sooner or later, disasters such as an asteroid collision or nuclear war could wipe us all out. But once we spread out into space and establish independent colonies, our future should be safe. There isn't anywhere like the Earth in the solar system, so we would have to go to another star."
