Character mistake: Early in the story Dr. Gibbs rationalises the story to come by using two cars traveling the road at greatly different speeds to illustrate "Einstein's theory of relativity". He basically says that the slower moving car seems to stand still as seen from the much faster car's point of view. But in real Einsteinian relativity, just the opposite happens. When two reference frames are traveling with respect to each other, each sees the other's time advancing more quickly.
