This program explores the complex landscape of time travel theory. Starting with Newton’s conclusions that time is fixed and events predetermined, then explaining Einstein’s eradication of those notions, the program focuses on exotic speculation begun in the latter part of the 20th century. Interviews with renowned theorists—including Dr. Frank Tipler, who proposes time travel via spinning structures in space, and Dr. Richard Gott, leading advocate of cosmic strings as time travel hubs—create an engaging tapestry of possibilities, among them the likelihood that reality may be a Newtonian puppet show after all.
