Dr. Michio Kaku believes there is nothing stopping us from building a holodeck straight out of Star Trek. He's on a mission to create an imaginary world indistinguishable from the real thing. At Rowan University, Michio experiences total immersion virtual reality as he takes on a T-Rex. Later, he goes on a patrol with the U.S. Army as he comes to grips with their omni-directional treadmill. Seth Goldstein at Carnegie Mellon explains how programmable matter will mean objects can shapeshift at the touch of a button. The only limits to a holodeck experience will be imagination itself.
