As for the whole "the science is ridiculous" argument about John Carter, yes it's unscientific, but why should that keep anyone from enjoying the story, any more than Star Wars or LOTR or Harry Potter?

Love it!
Actually, I wanted to call it "warp speed" but was afraid some would think I was a Trekkie. So many films... so many different names for it. But, shouldn't it be the speed of light is relevant; light speed is impossible. Whatever. 
OK, for homework extra credit here's a question I read in satire magazine once. It was a mock NASA astronaut test question. If a car manufacture invented an auto that could travel the speed of light, what would happen if the driver turned on the headlights? Good luck!
