Movie Takes Scientific Leaps

Jumper, the new movie starring Hayden Christensen, in which his character is able to teleport himself anywhere, opens today. Last month, Christensen, along with the movie's director, Doug Liman, and Massachusetts Institute of Technology physics professors Edward Farhi, an expert in quantum computers, and Max Tegmark, a cosmologist and scientific director of the Foundational Questions Institute, joined up for a panel discussion about the science behind the film—and real physics. —Heather Wax
