Roundtrip to Mars in One Day

I don't pretend to understand the intricacies of advanced physics, but this just seemed really cool to me. The article indicates that a couple of scientists think they can create a system that can get humans to travel places faster than light. This would allow travel to a star 11 light years away in 80 days or so. Hmmmm..... I thought Zefram Cochrane wasn't supposed to invent warp drive until 2063...
