Do you think human beings will ever inhabit a planet besides Earth?
Asked at Massachusetts Street on April 25, 2007
“Yes. I think if we’re given an infinite time frame, the possibilities should be infinite.”
“No. I don’t think we have enough time left on this planet to accomplish that.”
“I’m going to say yes. I think our urge to explore is an irresistible part of the human makeup.”
“No. I think people are going to destroy the world before that can happen.”
