Travel back in time, make a quick stop in Egypt, and then soar deep into outer space with a pair of popular (and kinda wacky) sci-fi epics. First up is Luc Besson's The Fifth Element, which is as colorful as it is incomprehensible -- and then it's Stargate, in which a fascinating space-travel premise quickly ends up in... a big pile of sand dunes. How exactly do waves of radiation generate human tissue? How could one gun do so many things? How hard is it to decipher a 7-symbol code? And what's up with that resurrection coffin? All this and more on this goofy episode of Science vs Fiction.
