Is The Alcubierre Warp Drive Possible?

Season 2 Episode 6

Inspired by Gene Roddenberry’s Star Trek, physicist Miguel Alcubierre set out to transform one of the cornerstones of science fiction iconography, the Warp Drive, into reality. But is it even possible? Can we "warp" the fabric of reality so that we can break the speed of light? And why is NASA actually exploring this potentiality?
