"The world is changing," said futurist John L. Petersen in his appearance on Tuesday night's show. "If we don't figure out how to deal with [our] problems in new ways, then they're going to run over the top of us," he cautioned.

Petersen went on to discuss quantum computing, time travel, nanotechnology, rapid climate change, melting of the polar ice caps, and other possibilities that would vastly alter our daily experience.

Despite the scenarios, our future doesn't have to be grim. Petersen believes, "If we learn how to adjust to and adapt to these kinds of things, it could precipitate a whole new kind of world--a whole new way of living."
